-The second argument, \type {operatortable}, should be a \LUA\ table where the

-by you) that are used to process those operators. The functions are called
-whenever the scanner finds one of these \PDF\ operators in the content stream(s).

-Internally, \type {pdfscanner.scan} loops over the \PDF\ operators in the

-operator. If that \PDF\ operator's name exists in \type {operatortable}, then the
-associated function is executed. After the function has run (or when there is no
-function to execute) the internal operand stack is cleared in preparation for the
-next operator, and processing continues.
+The \type {pdfe} library replaces the \type {epdf} library and provides an
+interface to \PDF\ files. It uses the same code as is used for \PDF\ image
+inclusion. The \type {pplib} library by Paweł Jackowski replaces the \type
+{poppler} (derived from \type {xpdf}) library.
-The \type {scanner} argument to the processing functions is needed because it
-offers various methods to get the actual operands from the internal operand
-stack.
+A \PDF\ file is basically a tree of objects and one descends into the tree via

+\startsubsection[title={\type {get[catalog|trailer|info]}}]
-The \type {epdf} library provides \LUA\ bindings to many \PDF\ access functions
-that are defined by the poppler \PDF\ viewer library (written in C$+{}+$ by
-Kristian H\o gsberg, based on xpdf by Derek Noonburg). Within \LUATEX\ xpdf
-functionality is being used since long time to embed \PDF\ files. The \type
-{epdf} library allows to scrutinize an external \PDF\ file. It gives access to
-its document structure: catalog, cross|-|reference table, individual pages,
-objects, annotations, info, and metadata. The \type {epdf} library only provides
-read|-|only access. At some point we might decide to limit the interface to a
-reasonable subset.
+\libindex {getcatalog}
+\libindex {gettrailer}
+\libindex {getinfo}
-For a start, a \PDF\ file is opened by \type {epdf.open()} with file name, e.g.:
+For accessing the document structure you start with the so called catalog, a
+dictionary:
\starttyping
-doc = epdf.open("foo.pdf")
+<pdfe dictionary> = pdfe.getcatalog(<pdfe document>)
\stoptyping
-This normally returns a \type {PDFDoc} userdata variable; but if the file could
-not be opened successfully, instead of a fatal error just the value \type {nil} is
-returned.
-
-All \LUA\ functions in the \type {epdf} library are named after the poppler
-functions listed in the poppler header files for the various classes, e.g., files
-\type {PDFDoc.h}, \type {Dict.h}, and \type {Array.h}. These files can be found
-in the poppler subdirectory within the \LUATEX\ sources. Which functions are
-already implemented in the \type {epdf} library can be found in the \LUATEX\
-source file \type {lepdflib.cc}. For using the \type {epdf} library, knowledge of
-the \PDF\ file architecture is indispensable.
-
-There are many different userdata types defined by the \type {epdf} library,
-currently these are \type {AnnotBorderStyle}, \type {AnnotBorder}, \type
-{Annots}, \type {Annot}, \type {Array}, \type {Attribute}, \type {Catalog}, \type
-{Dict}, \type {EmbFile}, \type {GString}, \type {LinkDest}, \type {Links}, \type
-{Link}, \type {ObjectStream}, \type {Object}, \type {PDFDoc}, \type
-{PDFRectangle}, \type {Page}, \type {Ref}, \type {Stream}, \type {StructElement},
-\type {StructTreeRoot} \type {TextSpan}, \type {XRefEntry} and \type {XRef}.
-
-All these userdata names and the \LUA\ access functions closely resemble the
-classes naming from the poppler header files, including the choice of mixed upper
-and lower case letters. The \LUA\ function calls use object|-|oriented syntax,
-e.g., the following calls return the \type {Page} object for page~1:
+The other two root dictionaries are accessed with:
\starttyping
-pageref = doc:getCatalog():getPageRef(1)
-pageobj = doc:getXRef():fetch(pageref.num, pageref.gen)
+<pdfe dictionary> = pdfe.gettrailer(<pdfe document>)
+<pdfe dictionary> = pdfe.getinfo(<pdfe document>)
\stoptyping
-But writing such chained calls is risky, as an intermediate function may return
-\type {nil} on error. Therefore between function calls there should be \LUA\ type
-checks (e.g., against \type {nil}) done. If a non|-|object item is requested (for
-instance a \type {Dict} item by calling \type {page:getPieceInfo()}, cf.~\type
-{Page.h}) but not available, the \LUA\ functions return \type {nil} (without
-error). If a function should return an \type {Object}, but it's not existing, a
-\type {Null} object is returned instead, also without error. This is in|-|line
-with poppler behavior.
+\stopsubsection
-All library objects have a \type {__gc} metamethod for garbage collection. The
-\type {__tostring} metamethod gives the type name for each object.

+\startsection[title={The \type {pdfscanner} library}][library=pdfscanner]
+
+\topicindex{\PDF+scanner}
+
+\libindex {scan}
+
+The \type {pdfscanner} library allows interpretation of \PDF\ content streams and
+\type {/ToUnicode} (cmap) streams. You can get those streams from the \type
+{pdfe} library, as explained in an earlier section. There is only a single
+top|-|level function in this library:
+
+\startfunctioncall
+pdfscanner.scan (<pdfe stream>, <table> operatortable, <table> info)
+pdfscanner.scan (<pdfe array>, <table> operatortable, <table> info)
+pdfscanner.scan (<string>, <table> operatortable, <table> info)
+\stopfunctioncall
+
+The first argument should be a \LUA\ string or a stream or array onject coming
+from the \type {pdfe} library. The second argument, \type {operatortable}, should
+be a \LUA\ table where the keys are \PDF\ operator name strings and the values
+are \LUA\ functions (defined by you) that are used to process those operators.
+The functions are called whenever the scanner finds one of these \PDF\ operators
+in the content stream(s). The functions are called with two arguments: the \type
+{scanner} object itself, and the \type {info} table that was passed are the third
+argument to \type {pdfscanner.scan}.
+
+Internally, \type {pdfscanner.scan} loops over the \PDF\ operators in the
+stream(s), collecting operands on an internal stack until it finds a \PDF\
+operator. If that \PDF\ operator's name exists in \type {operatortable}, then the
+associated function is executed. After the function has run (or when there is no
+function to execute) the internal operand stack is cleared in preparation for the
+next operator, and processing continues.
+
+The \type {scanner} argument to the processing functions is needed because it
+offers various methods to get the actual operands from the internal operand
+stack.
+
+A simple example of processing a \PDF's document stream could look like this:
+
+\starttyping
+local operatortable = { }
+
+operatortable.Do = function(scanner,info)
+ local resources = info.resources
+ if resources then
+ local val = scanner:pop()
+ local name = val[2]
+ local xobject = resources.XObject
+ print(info.space .. "Uses XObject " .. name)
+ local resources = xobject.Resources
+ if resources then
+ local newinfo = {
+ space = info.space .. " ",
+ resources = resources,
+ }
+ pdfscanner.scan(entry, operatortable, newinfo)
+ end
+ end
+end
+
+local function Analyze(filename)
+ local doc = pdfe.open(filename)
+ if doc then
+ local pages = doc.Pages
+ for i=1,#pages do
+ local page = pages[i]
+ local info = {
+ space = " " ,
+ resources = page.Resources,
+ }
+ print("Page " .. i)
+ -- pdfscanner.scan(page.Contents,operatortable,info)
+ pdfscanner.scan(page.Contents(),operatortable,info)
+ end
+ end
+end
+
+Analyze("foo.pdf")
+\stoptyping
+
+This example iterates over all the actual content in the \PDF, and prints out the
+found \type {XObject} names. While the code demonstrates quite some of the \type
+{pdfe} functions, let's focus on the type \type {pdfscanner} specific code
+instead.
+
+From the bottom up, the following line runs the scanner with the \PDF\ page's
+top|-|level content given in the first argument.
+
+The third argument, \type {info}, contains two entries: \type {space} is used to
+indent the printed output, and \type {resources} is needed so that embedded \type
+{XForms} can find their own content.
+
+The second argument, \type {operatortable} defines a processing function for a
+single \PDF\ operator, \type {Do}.
+
+The function \type {Do} prints the name of the current \type {XObject}, and then
+starts a new scanner for that object's content stream, under the condition that
+the \type {XObject} is in fact a \type {/Form}. That nested scanner is called
+with new \type {info} argument with an updated \type {space} value so that the
+indentation of the output nicely nests, and with a new \type {resources} field
+to help the next iteration down to properly process any other, embedded \type
+{XObject}s.
+
+Of course, this is not a very useful example in practice, but for the purpose of
+demonstrating \type {pdfscanner}, it is just long enough. It makes use of only
+one \type {scanner} method: \type {scanner:pop()}. That function pops the top
+operand of the internal stack, and returns a \LUA\ table where the object at index
+one is a string representing the type of the operand, and object two is its
+value.
+
+The list of possible operand types and associated \LUA\ value types is:
+
+\starttabulate[|l|l|]

+\NC \type{integer} \NC <number> \NC \NR

+\NC \type{string} \NC <string> \NC \NR
+\NC \type{array} \NC <table> \NC \NR
+\NC \type{dict} \NC <table> \NC \NR
+\LL
+\stoptabulate
+
+In case of \type {integer} or \type {real}, the value is always a \LUA\ (floating
+point) number. In case of \type {name}, the leading slash is always stripped.
+
+In case of \type {string}, please bear in mind that \PDF\ actually supports
+different types of strings (with different encodings) in different parts of the
+\PDF\ document, so you may need to reencode some of the results; \type {pdfscanner}
+always outputs the byte stream without reencoding anything. \type {pdfscanner}
+does not differentiate between literal strings and hexadecimal strings (the
+hexadecimal values are decoded), and it treats the stream data for inline images
+as a string that is the single operand for \type {EI}.
+
+In case of \type {array}, the table content is a list of \type {pop} return
+values and in case of \type {dict}, the table keys are \PDF\ name strings and the
+values are \type {pop} return values.
+

+\libindex{popname}
+\libindex{popstring}
+\libindex{poparray}
+\libindex{popdictionary}
+\libindex{popboolean}

+
+There are a few more methods defined that you can ask \type {scanner}:

+\NC \type{done} \NC abort further processing of this \type {scan()} call \NC \NR
+\LL
+\stoptabulate
+
+The \type {pop*} are convenience functions, and come in handy when you know the
+type of the operands beforehand (which you usually do, in \PDF). For example, the
+\type {Do} function could have used \type {local name = scanner:popname()}
+instead, because the single operand to the \type {Do} operator is always a \PDF\
+name object.
+
+The \type {done} function allows you to abort processing of a stream once you
+have learned everything you want to learn. This comes in handy while parsing
+\type {/ToUnicode}, because there usually is trailing garbage that you are not
+interested in. Without \type {done}, processing only ends at the end of the
+stream, possibly wasting \CPU\ cycles.
+
+{\em We keep the older names \type {popNumber}, \type {popName}, \type
+{popString}, \type {popArray}, \type {popDict} and \type {popBool} around.}

-integer. For the first two (\lpr {Umathcharnum} and \lpr {Umathcodenum}), the

-class, and the family data is kept in the topmost bits This means that the values
-for math families 128--255 are actually negative. For \lpr {Udelcodenum} there
-is no math class. The math family information is stored in the bits directly on

+\libindex{flush_properties_table}
+\libindex{get_properties_table}
+\libindex{set_properties_mode}
+
+Attributes are a convenient way to relate extra information to a node. You can
+assign them at the \TEX\ end as well as at the \LUA\ end and and consult them at
+the \LUA\ end. One big advantage is that they obey grouping. They are linked
+lists and normally checking for them is pretty efficient, even if you use a lot
+of them. A macro package has to provide some way to manage these attributes at the
+\TEX\ end because otherwise clashes in their usage can occur.
+
+Each node also can have a properties table and you can assign values to this
+table using the \type {setproperty} function and get properties using the \type
+{getproperty} function. Managing properties is way more demanding than managing
+attributes.
+
+Take the following example:
+
+\starttyping
+\directlua {
+ local n = node.new("glyph")
+
+ node.setproperty(n,"foo")
+ print(node.getproperty(n))
+
+ node.setproperty(n,"bar")
+ print(node.getproperty(n))
+
+ node.free(n)
+}
+\stoptyping
+
+This will print \type {foo} and \type {bar} which in itself is not that useful
+when multiple mechanisms want to use this feature. A variant is:
+
+\starttyping
+\directlua {
+ local n = node.new("glyph")
+
+ node.setproperty(n,{ one = "foo", two = "bar" })
+ print(node.getproperty(n).one)
+ print(node.getproperty(n).two)
+
+ node.free(n)
+}
+\stoptyping
+
+This time we store two properties with the node. It really makes sense to have a
+table as property because that way we can store more. But in order for that to
+work well you need to do it this way:
+
+\starttyping
+\directlua {
+ local n = node.new("glyph")
+
+ local t = node.getproperty(n)
+
+ if not t then
+ t = { }
+ node.setproperty(n,t)
+ end
+ t.one = "foo"
+ t.two = "bar"
+
+ print(node.getproperty(n).one)
+ print(node.getproperty(n).two)
+
+ node.free(n)
+}
+\stoptyping
+
+Here our own properties will not overwrite other users properties unless of
+course they use the same keys. So, eventually you will end up with something:
+
+\starttyping
+\directlua {
+ local n = node.new("glyph")
+
+ local t = node.getproperty(n)
+
+ if not t then
+ t = { }
+ node.setproperty(n,t)
+ end
+ t.myself = { one = "foo", two = "bar" }
+
+ print(node.getproperty(n).myself.one)
+ print(node.getproperty(n).myself.two)
+
+ node.free(n)
+}
+\stoptyping
+
+This assumes that only you use \type {myself} as subtable. The possibilities are
+endless but care is needed. For instance, the generic font handler that ships
+with \CONTEXT\ uses the \type {injections} subtable and you should not mess with
+that one!
+
+There are a few helper functions that you normally should not touch as user: \typ
+{flush_properties_table} will wipe the table (normally a bad idea), \typ
+{get_properties_table} and will give the table that stores properties (using
+direct entries) and you can best not mess too much with that one either because
+\LUATEX\ itself will make sure that entries related to nodes will get wiped when
+nodes get freed, so that the \LUA\ garbage collector can do its job. In fact, the
+main reason why we have this mechanism is that it saves the user (or macro
+package) some work. One can easily write a property mechanism in \LUA\ where
+after a shipout properties gets cleaned up but it's not entirely trivial to make
+sure that with each freed node also its properties get freed, due to the fact
+that there can be nodes left over for a next page. And having a callback bound to
+the node deallocator would add way to much overhead.
+
+Managing properties in the node (de)allocator functions is disabled by default
+and is enabled by:
+
+\starttyping
+node.set_properties_mode(true)
+\stoptyping
+
+When we copy a node list that has a table as property, there are several possibilities: we do the same as
+a new node, we copy the entry to the table in properties (a reference), we do
+a deep copy of a table in the properties, we create a new table and give it
+the original one as a metatable. After some experiments (that also included
+timing) with these scenarios we decided that a deep copy made no sense, nor
+did nilling. In the end both the shallow copy and the metatable variant were
+both ok, although the second one is slower. The most important aspect to keep
+in mind is that references to other nodes in properties no longer can be
+valid for that copy. We could use two tables (one unique and one shared) or
+metatables but that only complicates matters.
+
+When defining a new node, we could already allocate a table but it is rather easy
+to do that at the lua end e.g.\ using a metatable \type {__index} method. That
+way it is under macro package control. When deleting a node, we could keep the
+slot (e.g. setting it to false) but it could make memory consumption raise
+unneeded when we have temporary large node lists and after that only small lists.
+Both are not done.
+
+So in the end this is what happens now: when a node is copied, and it has a table
+as property, the new node will share that table. If the second argument of \typ
+{set_properties_mode} is \type {true} then a metatable approach is chosen: the
+copy gets its own table with the original table as metatable. If you use the
+generic font loader the mode is enabled that way.
+
+A few more xperiments were done. For instance: copy attributes to the properties
+so that we have fast access at the \LUA\ end. In the end the overhead is not
+compensated by speed and convenience, in fact, attributes are not that slow when
+it comes to accessing them. So this was rejected.
+
+Another experiment concerned a bitset in the node but again the gain compared to
+attributes was neglectable and given the small amount of available bits it also
+demands a pretty strong agreement over what bit represents what, and this is
+unlikely to succeed in the \TEX\ community. It doesn't pay off.
+
+Just in case one wonders why properties make sense: it is not so much speed that
+we gain, but more convenience: storing all kind of (temporary) data in attributes
+is no fun and this mechanism makes sure that properties are cleaned up when a
+node is freed. Also, the advantage of a more or less global properties table is
+that we stay at the \LUA\ end. An alternative is to store a reference in the node
+itself but that is complicated by the fact that the register has some limitations
+(no numeric keys) and we also don't want to mess with it too much.

+Although this needs to be used with care, you can also pass token or node
+userdata objects. These get injected into the stream. Tokens had best be valid
+tokens, while nodes need to be around when they get injected. Therefore it is
+important to realize the following:
+
+\startitemize
+\startitem
+ When you inject a token, you need to pass a valid token userdata object. This
+ object will be collected by \LUA\ when it no longer is referenced. When it gets
+ printed to \TEX\ the token itself gets copied so there is no interference with the
+ \LUA\ garbage collection. You manage the object yourself. Because tokens are
+ actually just numbers, there is no real extra overhead at the \TEX\ end.
+\stopitem
+\startitem
+ When you inject a node, you need to pass a valid node userdata object. The
+ node related to the object will not be collected by \LUA\ when it no longer
+ is referenced. It lives on at the \TEX\ end in its own memory space. When it
+ gets printed to \TEX\ the node reference is used assuming that node stays
+ around. There is no \LUA\ garbage collection involved. Again, you manage the
+ object yourself. The node itself is freed when \TEX\ is done with it.
+\stopitem
+\stopitemize
+
+If you consider the last remark you might realize that we have a problem when a
+printed mix of strings, tokens and nodes is reused. Inside \TEX\ the sequence
+becomes a linked list of input buffers. So, \type {"123"} or \type {"\foo{123}"}
+gets read and parsed on the fly, while \typ {<token userdata>} already is
+tokenized and effectively is a token list now. A \typ {<node userdata>} is also
+tokenized into a token list but it has a reference to a real node. Normally this
+goes fine. But now assume that you store the whole lot in a macro: in that case
+the tokenized node can be flushed many times. But, after the first such flush the
+node is used and its memory freed. You can prevent this by using copies which is
+controlled by setting \lpr {luacopyinputnodes} to a non|-|zero value. This is one

+These two functions start the interpretations and force its end. A runs normally
+boils down to \TEX\ entering the so called main loop. A token is fetched and
+depending on it current meaning some actions takes place. Sometimes that actions
+comes immediately, sometimes more scanning is needed. Quite often tokens get
+pushed back into the input. This all means that the \TEX\ scanner is constantly
+pushing and popping input states, but in the end after all the action is done
+returns to the main loop.
+
+Because of the fact that \TEX\ is in a complex dance of expanding, dealing with
+fonts, typesetting paragraphs, messing around with boxes, building pages, and so
+on, you cannot easily run a nested \TEX\ run (read nested main loop). However,
+there is an option to force a local run with \type {runtoks}. The content of the
+given token list register gets expanded locally after which we return to where we
+triggered this expansion, at the \LUA\ end. Instead a function can get passed
+that does some work. You have to make sure that at the end \TEX\ is in a sane

+An example of a (possible error triggering) complication is that \TEX\ expects to

-Changes since the last public release (1.6.34):
-
- Restored 21 of the contrib/pngsuite/i*.png, which do not cause test
- failures. Placed the remainder in contrib/pngsuite/interlaced/i*.png.
- Added calls to png_set_*() transforms commonly used by browsers to
- the fuzzer.
- Removed some unnecessary brackets in pngrtran.c
- Fixed miscellaneous typos (Patch by github user "luzpaz").
- Change "ASM C" to "C ASM" in CMakeLists.txt
- Fixed incorrect handling of bKGD chunk in sub-8-bit files (Cosmin)
- Added hardware optimization directories to zip and 7z distributions.
- Fixed incorrect bitmask for options.
- Fixed many spelling typos.
- Make png_get_iCCP consistent with man page (allow compression-type argument
- to be NULL, bug report by Lenard Szolnoki).
- Replaced the remaining uses of png_size_t with size_t (Cosmin)
- Fixed the calculation of row_factor in png_check_chunk_length
- (reported by Thuan Pham in SourceForge issue #278)
- Added missing parentheses to a macro definition
- (suggested by "irwir" in GitHub issue #216)

+IMPORTANT licensing update: libpng license v2
+---------------------------------------------
+
+The new libpng license comprises the terms and conditions from the zlib
+license, and the disclaimer from the Boost license.
+
+The legacy libpng license, used until libpng-1.6.35, is appended to the
+new license, following the precedent established in the Python Software
+Foundation License version 2.
-Glenn R-P
+From now on, the list of contributing authors shall be maintained in a
+separate AUTHORS file. The lists of previous contributing authors,
+mentioned in the legacy libpng license and considered to be an integral
+part of that license, are kept intact, with no further updates.
+
+
+Changes since the previous public release (version 1.6.35)
+----------------------------------------------------------
+
+ * Optimized png_do_expand_palette for ARM processors.
+ Improved performance by around 10-22% on a recent ARM Chromebook.
+ (Contributed by Richard Townsend, ARM Holdings)
+ * Fixed manipulation of machine-specific optimization options.
+ (Contributed by Vicki Pfau)
+ * Used memcpy instead of manual pointer arithmetic on Intel SSE2.
+ (Contributed by Samuel Williams)
+ * Fixed build errors with MSVC on ARM64.
+ (Contributed by Zhijie Liang)
+ * Fixed detection of libm in CMakeLists.
+ (Contributed by Cameron Cawley)
+ * Fixed incorrect creation of pkg-config file in CMakeLists.

+ * Fixed a build warning on OpenBSD.
+ (Contributed by Theo Buehler)
+ * Fixed various typos in comments.
+ (Contributed by "luz.paz")
+ * Raised the minimum required CMake version from 3.0.2 to 3.1.
+ * Removed yet more of the vestigial support for pre-ANSI C compilers.
+ * Removed ancient makefiles for ancient systems that have been broken
+ across all previous libpng-1.6.x versions.
+ * Removed the Y2K compliance statement and the export control
+ information.
+ * Applied various code style and documentation fixes.

TODO - list of things to do for libpng:
-Final bug fixes.
-Better C++ wrapper/full C++ implementation?
-Fix problem with C++ and EXTERN "C".
-cHRM transformation.
-Remove setjmp/longjmp usage in favor of returning error codes. As a start on
- this, minimize the use of png_error(), replacing them with
- png_warning(); return(0); or similar.
-Palette creation.
-Add "grayscale->palette" transformation and "palette->grayscale" detection.
-Improved dithering.
-Multi-lingual error and warning message support.
-Complete sRGB transformation (presently it simply uses gamma=0.45455).
-Man pages for function calls.
-Better documentation.
-Better filter selection
- (counting huffman bits/precompression? filter inertia? filter costs?).
-Histogram creation.
-Text conversion between different code pages (Latin-1 -> Mac and DOS).
-Avoid building gamma tables whenever possible.
-Use greater precision when changing to linear gamma for compositing against
- background and doing rgb-to-gray transformation.
-Investigate pre-incremented loop counters and other loop constructions.
-Add interpolated method of handling interlacing.
-Extend pngvalid.c to validate more of the libpng transformations.
-Refactor preprocessor conditionals to compile entire statements

-XVI. Y2K Compliance in libpng
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.6.35 are Y2K compliant. It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has two year fields. One is a 2-byte unsigned integer
-that will hold years up to 65535. The other, which is deprecated,
-holds the date in text format, and will hold years up to 9999.
-
-The integer is
- "png_uint_16 year" in png_time_struct.
-
-The string is
- "char time_buffer[29]" in png_struct. This is no longer used
-in libpng-1.6.x and will be removed from libpng-1.7.0.
-
-There are seven time-related functions:
-
- png_convert_to_rfc_1123_buffer() in png.c
- (formerly png_convert_to_rfc_1152() in error, and
- also formerly png_convert_to_rfc_1123())
- png_convert_from_struct_tm() in pngwrite.c, called
- in pngwrite.c
- png_convert_from_time_t() in pngwrite.c
- png_get_tIME() in pngget.c
- png_handle_tIME() in pngrutil.c, called in pngread.c
- png_set_tIME() in pngset.c
- png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment. The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year. There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control. The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant. It contains
-no date-related code.

-.SH XVI. Y2K Compliance in libpng
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.6.35 are Y2K compliant. It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has two year fields. One is a 2-byte unsigned integer
-that will hold years up to 65535. The other, which is deprecated,
-holds the date in text format, and will hold years up to 9999.
-
-The integer is
- "png_uint_16 year" in png_time_struct.
-
-The string is
- "char time_buffer[29]" in png_struct. This is no longer used
-in libpng-1.6.x and will be removed from libpng-1.7.0.
-
-There are seven time-related functions:
-
- png_convert_to_rfc_1123_buffer() in png.c
- (formerly png_convert_to_rfc_1152() in error, and
- also formerly png_convert_to_rfc_1123())
- png_convert_from_struct_tm() in pngwrite.c, called
- in pngwrite.c
- png_convert_from_time_t() in pngwrite.c
- png_get_tIME() in pngget.c
- png_handle_tIME() in pngrutil.c, called in pngread.c
- png_set_tIME() in pngset.c
- png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment. The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year. There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control. The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant. It contains
-no date-related code.

- * Y2K compliance in libpng:
- * =========================
- *
- * July 15, 2018
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.6.35 are Y2K compliant. It is my belief that
- * earlier versions were also Y2K compliant.
- *
- * Libpng only has two year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other, which is deprecated,
- * holds the date in text format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The string is
- * "char time_buffer[29]" in png_struct. This is no longer used
- * in libpng-1.6.x and will be removed from libpng-1.7.0.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123_buffer() in png.c
- * (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
- * png_convert_to_rfc_1152() in error prior to libpng-0.98)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system
- * clock time, which returns (year - 1900), which we properly convert to
- * the full 4-digit year. There is a possibility that libpng applications
- * are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
- * function, or that they are incorrectly passing only a 2-digit year
- * instead of "year - 1900" into the png_convert_from_struct_tm() function,
- * but this is not under our control. The libpng documentation has always
- * stated that it works with 4-digit years, and the APIs have been
- * documented as such.
- *
- * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
- * integer to hold the year, and can hold years as large as 65535.
- *
- * zlib, upon which libpng depends, is also Y2K compliant. It contains
- * no date-related code.

+You must enter some information in zlib.props before attempting to
+build with this 'solution'. Please read and edit zlib.props first.
+You will probably not be familiar with the contents of zlib.props -
+do not worry, it is mostly harmless.
This is all you need to do to build the 'release' and 'release library'
configurations.
Debugging
-=========
+---------
The release configurations default to /Ox optimization. Full debugging
-information is produced (in the .pdb), but if you encounter a problem the
-optimization may make it difficult to debug. Simply rebuild with a lower
-optimization level (e.g. /Od.)

Linking your application
-========================
-Normally you should link against the 'release' configuration. This builds a
-DLL for libpng with the default runtime options used by Visual Studio 2010.
-In particular the runtime library is the "MultiThreaded DLL" version.
-If you use Visual Studio defaults to build your application you will have no
-problems.
-
-If you don't use the Visual Studio defaults your application must still be
-built with the default runtime option (/MD). If, for some reason, it is not
-then your application will crash inside libpng16.dll as soon as libpng
-tries to read from a file handle you pass in.
-
-If you do not want to use the DLL, for example for a very small application,
-the 'release library' configuration may be more appropriate. This is built
-with a non-standard runtime library - the "MultiThreaded" version. When you
-build your application it must be compiled with this option (/MT), otherwise
-it will not build (if you are lucky) or crash (if you are not.) See the
-WARNING file that is distributed along with this readme.txt.

-=================
+-----------------
You have enough information to build a working application.
Debug versions have limited support
-===================================
-This solution includes limited support for debug versions of libpng. You
-do not need these unless your own solution itself uses debug builds (it is
-far more effective to debug on the release builds, there is no point building
-a special debug build unless you have heap corruption problems that you can't
-track down.)

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- LT_SYS_LIBRARY_PATH
- User-defined run-time library search path.
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-.SH NAME
-lua \- Lua interpreter
-.SH SYNOPSIS
-.B lua
-[
-.I options
-]
-[
-.I script
-[
-.I args
-]
-]
-.SH DESCRIPTION
-.B lua
-is the standalone Lua interpreter.
-It loads and executes Lua programs,
-either in textual source form or
-in precompiled binary form.
-(Precompiled binaries are output by
-.BR luac ,
-the Lua compiler.)
-.B lua
-can be used as a batch interpreter and also interactively.
-.LP
-The given
-.I options
-are handled in order and then
-the Lua program in file
-.I script
-is loaded and executed.
-The given
-.I args
-are available to
-.I script
-as strings in a global table named
-.BR arg .
-If no options or arguments are given,
-then
-.B "\-v \-i"
-is assumed when the standard input is a terminal;
-otherwise,
-.B "\-"
-is assumed.
-.LP
-In interactive mode,
-.B lua
-prompts the user,
-reads lines from the standard input,
-and executes them as they are read.
-If a line does not contain a complete statement,
-then a secondary prompt is displayed and
-lines are read until a complete statement is formed or
-a syntax error is found.
-If a line starts with
-.BR '=' ,
-then
-.B lua
-evaluates and displays
-the values of the expressions in the remainder of the line.
-.LP
-At the very start,
-before even handling the command line,
-.B lua
-checks the contents of the environment variables
-.B LUA_INIT_5_2
-or
-.BR LUA_INIT ,
-in that order.
-If the contents is of the form
-.RI '@ filename ',
-then
-.I filename
-is executed.
-Otherwise, the string is assumed to be a Lua statement and is executed.
-.SH OPTIONS
-.TP
-.BI \-e " stat"
-execute statement
-.IR stat .
-.TP
-.B \-i
-enter interactive mode after executing
-.IR script .
-.TP
-.BI \-l " name"
-execute the equivalent of
-.IB name =require(' name ')
-before executing
-.IR script .
-.TP
-.B \-v
-show version information.
-.TP
-.B \-E
-ignore environment variables.
-.TP
-.B \-\-
-stop handling options.
-.TP
-.B \-
-stop handling options and execute the standard input as a file.

-.TH LUAC 1 "$Date: 2011/11/16 13:53:40 $"
-.SH NAME
-luac \- Lua compiler
-.SH SYNOPSIS
-.B luac
-[
-.I options
-] [
-.I filenames
-]
-.SH DESCRIPTION
-.B luac
-is the Lua compiler.
-It translates programs written in the Lua programming language
-into binary files containing precompiled chunks
-that can be later loaded and executed.
-.LP
-The main advantages of precompiling chunks are:
-faster loading,
-protecting source code from accidental user changes,
-and
-off-line syntax checking.
-Precompiling does not imply faster execution
-because in Lua chunks are always compiled into bytecodes before being executed.
-.B luac
-simply allows those bytecodes to be saved in a file for later execution.
-Precompiled chunks are not necessarily smaller than the corresponding source.
-The main goal in precompiling is faster loading.
-.LP
-In the command line,
-you can mix
-text files containing Lua source and
-binary files containing precompiled chunks.
-.B luac
-produces a single output file containing the combined bytecodes
-for all files given.
-Executing the combined file is equivalent to executing the given files.
-By default,
-the output file is named
-.BR luac.out ,
-but you can change this with the
-.B \-o
-option.
-.LP
-Precompiled chunks are
-.I not
-portable across different architectures.
-Moreover,
-the internal format of precompiled chunks
-is likely to change when a new version of Lua is released.
-Make sure you save the source files of all Lua programs that you precompile.
-.LP
-.SH OPTIONS
-.TP
-.B \-l
-produce a listing of the compiled bytecode for Lua's virtual machine.
-Listing bytecodes is useful to learn about Lua's virtual machine.
-If no files are given, then
-.B luac
-loads
-.B luac.out
-and lists its contents.
-Use
-.B \-l \-l
-for a full listing.
-.TP
-.BI \-o " file"
-output to
-.IR file ,
-instead of the default
-.BR luac.out .
-(You can use
-.B "'\-'"
-for standard output,
-but not on platforms that open standard output in text mode.)
-The output file may be one of the given files because
-all files are loaded before the output file is written.
-Be careful not to overwrite precious files.
-.TP
-.B \-p
-load files but do not generate any output file.
-Used mainly for syntax checking and for testing precompiled chunks:
-corrupted files will probably generate errors when loaded.
-If no files are given, then
-.B luac
-loads
-.B luac.out
-and tests its contents.
-No messages are displayed if the file loads without errors.
-.TP
-.B \-s
-strip debug information before writing the output file.
-This saves some space in very large chunks,
-but if errors occur when running a stripped chunk,
-then the error messages may not contain the full information they usually do.
-In particular,
-line numbers and names of local variables are lost.
-.TP
-.B \-v
-show version information.
-.TP
-.B \-\-
-stop handling options.
-.TP
-.B \-
-stop handling options and process standard input.
-.SH "SEE ALSO"

-<h1>1 – <a name="1">Introduction</a></h1>
-
-<p>
-Lua is an extension programming language designed to support
-general procedural programming with data description
-facilities.
-It also offers good support for object-oriented programming,
-functional programming, and data-driven programming.
-Lua is intended to be used as a powerful, lightweight,
-embeddable scripting language for any program that needs one.
-Lua is implemented as a library, written in <em>clean C</em>,
-the common subset of Standard C and C++.
-
-
-<p>
-Being an extension language, Lua has no notion of a "main" program:
-it only works <em>embedded</em> in a host client,
-called the <em>embedding program</em> or simply the <em>host</em>.
-The host program can invoke functions to execute a piece of Lua code,
-can write and read Lua variables,
-and can register C functions to be called by Lua code.
-Through the use of C functions, Lua can be augmented to cope with
-a wide range of different domains,
-thus creating customized programming languages sharing a syntactical framework.
-The Lua distribution includes a sample host program called <code>lua</code>,
-which uses the Lua library to offer a complete, standalone Lua interpreter,
-for interactive or batch use.
-
-
-<p>
-Lua is free software,
-and is provided as usual with no guarantees,
-as stated in its license.
-The implementation described in this manual is available
-at Lua's official web site, <code>www.lua.org</code>.
-
-
-<p>
-Like any other reference manual,
-this document is dry in places.
-For a discussion of the decisions behind the design of Lua,
-see the technical papers available at Lua's web site.
-For a detailed introduction to programming in Lua,
-see Roberto's book, <em>Programming in Lua</em>.
-
-
-
-<h1>2 – <a name="2">Basic Concepts</a></h1>
-
-<p>
-This section describes the basic concepts of the language.
-
-
-
-<h2>2.1 – <a name="2.1">Values and Types</a></h2>
-
-<p>
-Lua is a <em>dynamically typed language</em>.
-This means that
-variables do not have types; only values do.
-There are no type definitions in the language.
-All values carry their own type.
-
-
-<p>
-All values in Lua are <em>first-class values</em>.
-This means that all values can be stored in variables,
-passed as arguments to other functions, and returned as results.
-
-
-<p>
-There are eight basic types in Lua:
-<em>nil</em>, <em>boolean</em>, <em>number</em>,
-<em>string</em>, <em>function</em>, <em>userdata</em>,
-<em>thread</em>, and <em>table</em>.
-<em>Nil</em> is the type of the value <b>nil</b>,
-whose main property is to be different from any other value;
-it usually represents the absence of a useful value.
-<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>.
-Both <b>nil</b> and <b>false</b> make a condition false;
-any other value makes it true.
-<em>Number</em> represents real (double-precision floating-point) numbers.
-Operations on numbers follow the same rules of
-the underlying C implementation,
-which, in turn, usually follows the IEEE 754 standard.
-(It is easy to build Lua interpreters that use other
-internal representations for numbers,
-such as single-precision floats or long integers;
-see file <code>luaconf.h</code>.)
-<em>String</em> represents immutable sequences of bytes.
-
-Lua is 8-bit clean:
-strings can contain any 8-bit value,
-including embedded zeros ('<code>\0</code>').
-
-
-<p>
-Lua can call (and manipulate) functions written in Lua and
-functions written in C
-(see <a href="#3.4.9">§3.4.9</a>).
-
-
-<p>
-The type <em>userdata</em> is provided to allow arbitrary C data to
-be stored in Lua variables.
-A userdata value is a pointer to a block of raw memory.
-There are two kinds of userdata:
-full userdata, where the block of memory is managed by Lua,
-and light userdata, where the block of memory is managed by the host.
-Userdata has no predefined operations in Lua,
-except assignment and identity test.
-By using <em>metatables</em>,
-the programmer can define operations for full userdata values
-(see <a href="#2.4">§2.4</a>).
-Userdata values cannot be created or modified in Lua,
-only through the C API.
-This guarantees the integrity of data owned by the host program.
-
-
-<p>
-The type <em>thread</em> represents independent threads of execution
-and it is used to implement coroutines (see <a href="#2.6">§2.6</a>).
-Do not confuse Lua threads with operating-system threads.
-Lua supports coroutines on all systems,
-even those that do not support threads.
-
-
-<p>
-The type <em>table</em> implements associative arrays,
-that is, arrays that can be indexed not only with numbers,
-but with any Lua value except <b>nil</b> and NaN
-(<em>Not a Number</em>, a special numeric value used to represent
-undefined or unrepresentable results, such as <code>0/0</code>).
-Tables can be <em>heterogeneous</em>;
-that is, they can contain values of all types (except <b>nil</b>).
-Any key with value <b>nil</b> is not considered part of the table.
-Conversely, any key that is not part of a table has
-an associated value <b>nil</b>.
-
-
-<p>
-Tables are the sole data structuring mechanism in Lua;
-they can be used to represent ordinary arrays, sequences,
-symbol tables, sets, records, graphs, trees, etc.
-To represent records, Lua uses the field name as an index.
-The language supports this representation by
-providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
-There are several convenient ways to create tables in Lua
-(see <a href="#3.4.8">§3.4.8</a>).
-
-
-<p>
-We use the term <em>sequence</em> to denote a table where
-the set of all positive numeric keys is equal to <em>{1..n}</em>
-for some integer <em>n</em>,
-which is called the length of the sequence (see <a href="#3.4.6">§3.4.6</a>).
-
-
-<p>
-Like indices,
-the values of table fields can be of any type.
-In particular,
-because functions are first-class values,
-table fields can contain functions.
-Thus tables can also carry <em>methods</em> (see <a href="#3.4.10">§3.4.10</a>).
-
-
-<p>
-The indexing of tables follows
-the definition of raw equality in the language.
-The expressions <code>a[i]</code> and <code>a[j]</code>
-denote the same table element
-if and only if <code>i</code> and <code>j</code> are raw equal
-(that is, equal without metamethods).
-
-
-<p>
-Tables, functions, threads, and (full) userdata values are <em>objects</em>:
-variables do not actually <em>contain</em> these values,
-only <em>references</em> to them.
-Assignment, parameter passing, and function returns
-always manipulate references to such values;
-these operations do not imply any kind of copy.
-
-
-<p>
-The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
-of a given value (see <a href="#6.1">§6.1</a>).

-<h2>2.2 – <a name="2.2">Environments and the Global Environment</a></h2>
-
-<p>
-As will be discussed in <a href="#3.2">§3.2</a> and <a href="#3.3.3">§3.3.3</a>,
-any reference to a global name <code>var</code> is syntactically translated
-to <code>_ENV.var</code>.
-Moreover, every chunk is compiled in the scope of
-an external local variable called <code>_ENV</code> (see <a href="#3.3.2">§3.3.2</a>),
-so <code>_ENV</code> itself is never a global name in a chunk.
-
-
-<p>
-Despite the existence of this external <code>_ENV</code> variable and
-the translation of global names,
-<code>_ENV</code> is a completely regular name.
-In particular,
-you can define new variables and parameters with that name.
-Each reference to a global name uses the <code>_ENV</code> that is
-visible at that point in the program,
-following the usual visibility rules of Lua (see <a href="#3.5">§3.5</a>).
-
-
-<p>
-Any table used as the value of <code>_ENV</code> is called an <em>environment</em>.
-
-
-<p>
-Lua keeps a distinguished environment called the <em>global environment</em>.
-This value is kept at a special index in the C registry (see <a href="#4.5">§4.5</a>).
-In Lua, the variable <a href="#pdf-_G"><code>_G</code></a> is initialized with this same value.
-
-
-<p>
-When Lua compiles a chunk,
-it initializes the value of its <code>_ENV</code> upvalue
-with the global environment (see <a href="#pdf-load"><code>load</code></a>).
-Therefore, by default,
-global variables in Lua code refer to entries in the global environment.
-Moreover, all standard libraries are loaded in the global environment
-and several functions there operate on that environment.
-You can use <a href="#pdf-load"><code>load</code></a> (or <a href="#pdf-loadfile"><code>loadfile</code></a>)
-to load a chunk with a different environment.
-(In C, you have to load the chunk and then change the value
-of its first upvalue.)
-
-
-<p>
-If you change the global environment in the registry
-(through C code or the debug library),
-all chunks loaded after the change will get the new environment.
-Previously loaded chunks are not affected, however,
-as each has its own reference to the environment in its <code>_ENV</code> variable.
-Moreover, the variable <a href="#pdf-_G"><code>_G</code></a>
-(which is stored in the original global environment)
-is never updated by Lua.
-
-
-
-
-
-<h2>2.3 – <a name="2.3">Error Handling</a></h2>
-
-<p>
-Because Lua is an embedded extension language,
-all Lua actions start from C code in the host program
-calling a function from the Lua library (see <a href="#lua_pcall"><code>lua_pcall</code></a>).
-Whenever an error occurs during
-the compilation or execution of a Lua chunk,
-control returns to the host,
-which can take appropriate measures
-(such as printing an error message).
-
-
-<p>
-Lua code can explicitly generate an error by calling the
-<a href="#pdf-error"><code>error</code></a> function.
-If you need to catch errors in Lua,
-you can use <a href="#pdf-pcall"><code>pcall</code></a> or <a href="#pdf-xpcall"><code>xpcall</code></a>
-to call a given function in <em>protected mode</em>.
-
-
-<p>
-Whenever there is an error,
-an <em>error object</em> (also called an <em>error message</em>)
-is propagated with information about the error.
-Lua itself only generates errors where the error object is a string,
-but programs may generate errors with
-any value for the error object.
-
-
-<p>
-When you use <a href="#pdf-xpcall"><code>xpcall</code></a> or <a href="#lua_pcall"><code>lua_pcall</code></a>,
-you may give a <em>message handler</em>
-to be called in case of errors.
-This function is called with the original error message
-and returns a new error message.
-It is called before the error unwinds the stack,
-so that it can gather more information about the error,
-for instance by inspecting the stack and creating a stack traceback.
-This message handler is still protected by the protected call;
-so, an error inside the message handler
-will call the message handler again.
-If this loop goes on, Lua breaks it and returns an appropriate message.
-
-
-
-
-
-<h2>2.4 – <a name="2.4">Metatables and Metamethods</a></h2>
-
-<p>
-Every value in Lua can have a <em>metatable</em>.
-This <em>metatable</em> is an ordinary Lua table
-that defines the behavior of the original value
-under certain special operations.
-You can change several aspects of the behavior
-of operations over a value by setting specific fields in its metatable.
-For instance, when a non-numeric value is the operand of an addition,
-Lua checks for a function in the field "<code>__add</code>" of the value's metatable.
-If it finds one,
-Lua calls this function to perform the addition.
-
-
-<p>
-The keys in a metatable are derived from the <em>event</em> names;
-the corresponding values are called <em>metamethods</em>.
-In the previous example, the event is <code>"add"</code>
-and the metamethod is the function that performs the addition.
-
-
-<p>
-You can query the metatable of any value
-using the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
-
-
-<p>
-You can replace the metatable of tables
-using the <a href="#pdf-setmetatable"><code>setmetatable</code></a> function.
-You cannot change the metatable of other types from Lua
-(except by using the debug library);
-you must use the C API for that.
-
-
-<p>
-Tables and full userdata have individual metatables
-(although multiple tables and userdata can share their metatables).
-Values of all other types share one single metatable per type;
-that is, there is one single metatable for all numbers,
-one for all strings, etc.
-By default, a value has no metatable,
-but the string library sets a metatable for the string type (see <a href="#6.4">§6.4</a>).
-
-
-<p>
-A metatable controls how an object behaves in arithmetic operations,
-order comparisons, concatenation, length operation, and indexing.
-A metatable also can define a function to be called
-when a userdata or a table is garbage collected.
-When Lua performs one of these operations over a value,
-it checks whether this value has a metatable with the corresponding event.
-If so, the value associated with that key (the metamethod)
-controls how Lua will perform the operation.
-
-
-<p>
-Metatables control the operations listed next.
-Each operation is identified by its corresponding name.
-The key for each operation is a string with its name prefixed by
-two underscores, '<code>__</code>';
-for instance, the key for operation "add" is the
-string "<code>__add</code>".
-
-
-<p>
-The semantics of these operations is better explained by a Lua function
-describing how the interpreter executes the operation.
-The code shown here in Lua is only illustrative;
-the real behavior is hard coded in the interpreter
-and it is much more efficient than this simulation.
-All functions used in these descriptions
-(<a href="#pdf-rawget"><code>rawget</code></a>, <a href="#pdf-tonumber"><code>tonumber</code></a>, etc.)
-are described in <a href="#6.1">§6.1</a>.
-In particular, to retrieve the metamethod of a given object,
-we use the expression
-
-<pre>
- metatable(obj)[event]
-</pre><p>
-This should be read as
-
-<pre>
- rawget(getmetatable(obj) or {}, event)
-</pre><p>
-This means that the access to a metamethod does not invoke other metamethods,
-and access to objects with no metatables does not fail
-(it simply results in <b>nil</b>).
-
-
-<p>
-For the unary <code>-</code> and <code>#</code> operators,
-the metamethod is called with a dummy second argument.
-This extra argument is only to simplify Lua's internals;
-it may be removed in future versions and therefore it is not present
-in the following code.
-(For most uses this extra argument is irrelevant.)

-<h2>2.5 – <a name="2.5">Garbage Collection</a></h2>
-
-<p>
-Lua performs automatic memory management.
-This means that
-you have to worry neither about allocating memory for new objects
-nor about freeing it when the objects are no longer needed.
-Lua manages memory automatically by running
-a <em>garbage collector</em> to collect all <em>dead objects</em>
-(that is, objects that are no longer accessible from Lua).
-All memory used by Lua is subject to automatic management:
-strings, tables, userdata, functions, threads, internal structures, etc.
-
-
-<p>
-Lua implements an incremental mark-and-sweep collector.
-It uses two numbers to control its garbage-collection cycles:
-the <em>garbage-collector pause</em> and
-the <em>garbage-collector step multiplier</em>.
-Both use percentage points as units
-(e.g., a value of 100 means an internal value of 1).
-
-
-<p>
-The garbage-collector pause
-controls how long the collector waits before starting a new cycle.
-Larger values make the collector less aggressive.
-Values smaller than 100 mean the collector will not wait to
-start a new cycle.
-A value of 200 means that the collector waits for the total memory in use
-to double before starting a new cycle.
-
-
-<p>
-The garbage-collector step multiplier
-controls the relative speed of the collector relative to
-memory allocation.
-Larger values make the collector more aggressive but also increase
-the size of each incremental step.
-Values smaller than 100 make the collector too slow and
-can result in the collector never finishing a cycle.
-The default is 200,
-which means that the collector runs at "twice"
-the speed of memory allocation.
-
-
-<p>
-If you set the step multiplier to a very large number
-(larger than 10% of the maximum number of
-bytes that the program may use),
-the collector behaves like a stop-the-world collector.
-If you then set the pause to 200,
-the collector behaves as in old Lua versions,
-doing a complete collection every time Lua doubles its
-memory usage.
-
-
-<p>
-You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C
-or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
-You can also use these functions to control
-the collector directly (e.g., stop and restart it).
-
-
-<p>
-As an experimental feature in Lua 5.2,
-you can change the collector's operation mode
-from incremental to <em>generational</em>.
-A <em>generational collector</em> assumes that most objects die young,
-and therefore it traverses only young (recently created) objects.
-This behavior can reduce the time used by the collector,
-but also increases memory usage (as old dead objects may accumulate).
-To mitigate this second problem,
-from time to time the generational collector performs a full collection.
-Remember that this is an experimental feature;
-you are welcome to try it,
-but check your gains.
-
-
-
-<h3>2.5.1 – <a name="2.5.1">Garbage-Collection Metamethods</a></h3>
-
-<p>
-You can set garbage-collector metamethods for tables
-and, using the C API,
-for full userdata (see <a href="#2.4">§2.4</a>).
-These metamethods are also called <em>finalizers</em>.
-Finalizers allow you to coordinate Lua's garbage collection
-with external resource management
-(such as closing files, network or database connections,
-or freeing your own memory).
-
-
-<p>
-For an object (table or userdata) to be finalized when collected,
-you must <em>mark</em> it for finalization.
-
-You mark an object for finalization when you set its metatable
-and the metatable has a field indexed by the string "<code>__gc</code>".
-Note that if you set a metatable without a <code>__gc</code> field
-and later create that field in the metatable,
-the object will not be marked for finalization.
-However, after an object is marked,
-you can freely change the <code>__gc</code> field of its metatable.
-
-
-<p>
-When a marked object becomes garbage,
-it is not collected immediately by the garbage collector.
-Instead, Lua puts it in a list.
-After the collection,
-Lua does the equivalent of the following function
-for each object in that list:
-
-<pre>
- function gc_event (obj)
- local h = metatable(obj).__gc
- if type(h) == "function" then
- h(obj)
- end
- end
-</pre>
-
-<p>
-At the end of each garbage-collection cycle,
-the finalizers for objects are called in
-the reverse order that they were marked for collection,
-among those collected in that cycle;
-that is, the first finalizer to be called is the one associated
-with the object marked last in the program.
-The execution of each finalizer may occur at any point during
-the execution of the regular code.
-
-
-<p>
-Because the object being collected must still be used by the finalizer,
-it (and other objects accessible only through it)
-must be <em>resurrected</em> by Lua.
-Usually, this resurrection is transient,
-and the object memory is freed in the next garbage-collection cycle.
-However, if the finalizer stores the object in some global place
-(e.g., a global variable),
-then there is a permanent resurrection.
-In any case,
-the object memory is freed only when it becomes completely inaccessible;
-its finalizer will never be called twice.
-
-
-<p>
-When you close a state (see <a href="#lua_close"><code>lua_close</code></a>),
-Lua calls the finalizers of all objects marked for finalization,
-following the reverse order that they were marked.
-If any finalizer marks new objects for collection during that phase,
-these new objects will not be finalized.
-
-
-
-
-
-<h3>2.5.2 – <a name="2.5.2">Weak Tables</a></h3>
-
-<p>
-A <em>weak table</em> is a table whose elements are
-<em>weak references</em>.
-A weak reference is ignored by the garbage collector.
-In other words,
-if the only references to an object are weak references,
-then the garbage collector will collect that object.
-
-
-<p>
-A weak table can have weak keys, weak values, or both.
-A table with weak keys allows the collection of its keys,
-but prevents the collection of its values.
-A table with both weak keys and weak values allows the collection of
-both keys and values.
-In any case, if either the key or the value is collected,
-the whole pair is removed from the table.
-The weakness of a table is controlled by the
-<code>__mode</code> field of its metatable.
-If the <code>__mode</code> field is a string containing the character '<code>k</code>',
-the keys in the table are weak.
-If <code>__mode</code> contains '<code>v</code>',
-the values in the table are weak.
-
-
-<p>
-A table with weak keys and strong values
-is also called an <em>ephemeron table</em>.
-In an ephemeron table,
-a value is considered reachable only if its key is reachable.
-In particular,
-if the only reference to a key comes through its value,
-the pair is removed.
-
-
-<p>
-Any change in the weakness of a table may take effect only
-at the next collect cycle.
-In particular, if you change the weakness to a stronger mode,
-Lua may still collect some items from that table
-before the change takes effect.
-
-
-<p>
-Only objects that have an explicit construction
-are removed from weak tables.
-Values, such as numbers and light C functions,
-are not subject to garbage collection,
-and therefore are not removed from weak tables
-(unless its associated value is collected).
-Although strings are subject to garbage collection,
-they do not have an explicit construction,
-and therefore are not removed from weak tables.
-
-
-<p>
-Resurrected objects
-(that is, objects being finalized
-and objects accessible only through objects being finalized)
-have a special behavior in weak tables.
-They are removed from weak values before running their finalizers,
-but are removed from weak keys only in the next collection
-after running their finalizers, when such objects are actually freed.
-This behavior allows the finalizer to access properties
-associated with the object through weak tables.
-
-
-<p>
-If a weak table is among the resurrected objects in a collection cycle,
-it may not be properly cleared until the next cycle.
-
-
-
-
-
-
-
-<h2>2.6 – <a name="2.6">Coroutines</a></h2>
-
-<p>
-Lua supports coroutines,
-also called <em>collaborative multithreading</em>.
-A coroutine in Lua represents an independent thread of execution.
-Unlike threads in multithread systems, however,
-a coroutine only suspends its execution by explicitly calling
-a yield function.
-
-
-<p>
-You create a coroutine by calling <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
-Its sole argument is a function
-that is the main function of the coroutine.
-The <code>create</code> function only creates a new coroutine and
-returns a handle to it (an object of type <em>thread</em>);
-it does not start the coroutine.
-
-
-<p>
-You execute a coroutine by calling <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-passing as its first argument
-a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the coroutine starts its execution,
-at the first line of its main function.
-Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed on
-to the coroutine main function.
-After the coroutine starts running,
-it runs until it terminates or <em>yields</em>.
-
-
-<p>
-A coroutine can terminate its execution in two ways:
-normally, when its main function returns
-(explicitly or implicitly, after the last instruction);
-and abnormally, if there is an unprotected error.
-In the first case, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
-plus any values returned by the coroutine main function.
-In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
-plus an error message.
-
-
-<p>
-A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-When a coroutine yields,
-the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
-even if the yield happens inside nested function calls
-(that is, not in the main function,
-but in a function directly or indirectly called by the main function).
-In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
-plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-The next time you resume the same coroutine,
-it continues its execution from the point where it yielded,
-with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
-arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-
-
-<p>
-Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
-but instead of returning the coroutine itself,
-it returns a function that, when called, resumes the coroutine.
-Any arguments passed to this function
-go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-except the first one (the boolean error code).
-Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors;
-any error is propagated to the caller.
-
-
-<p>
-As an example of how coroutines work,
-consider the following code:
-
-<pre>
- function foo (a)
- print("foo", a)
- return coroutine.yield(2*a)
- end
-
- co = coroutine.create(function (a,b)
- print("co-body", a, b)
- local r = foo(a+1)
- print("co-body", r)
- local r, s = coroutine.yield(a+b, a-b)
- print("co-body", r, s)
- return b, "end"
- end)
-
- print("main", coroutine.resume(co, 1, 10))
- print("main", coroutine.resume(co, "r"))
- print("main", coroutine.resume(co, "x", "y"))
- print("main", coroutine.resume(co, "x", "y"))
-</pre><p>
-When you run it, it produces the following output:
-
-<pre>
- co-body 1 10
- foo 2
- main true 4
- co-body r
- main true 11 -9
- co-body x y
- main true 10 end
- main false cannot resume dead coroutine
-</pre>
-
-<p>
-You can also create and manipulate coroutines through the C API:
-see functions <a href="#lua_newthread"><code>lua_newthread</code></a>, <a href="#lua_resume"><code>lua_resume</code></a>,
-and <a href="#lua_yield"><code>lua_yield</code></a>.

-<h1>3 – <a name="3">The Language</a></h1>
-
-<p>
-This section describes the lexis, the syntax, and the semantics of Lua.
-In other words,
-this section describes
-which tokens are valid,
-how they can be combined,
-and what their combinations mean.
-
-
-<p>
-Language constructs will be explained using the usual extended BNF notation,
-in which
-{<em>a</em>} means 0 or more <em>a</em>'s, and
-[<em>a</em>] means an optional <em>a</em>.
-Non-terminals are shown like non-terminal,
-keywords are shown like <b>kword</b>,
-and other terminal symbols are shown like ‘<b>=</b>’.
-The complete syntax of Lua can be found in <a href="#9">§9</a>
-at the end of this manual.
-
-
-
-<h2>3.1 – <a name="3.1">Lexical Conventions</a></h2>
-
-<p>
-Lua is a free-form language.
-It ignores spaces (including new lines) and comments
-between lexical elements (tokens),
-except as delimiters between names and keywords.
-
-
-<p>
-<em>Names</em>
-(also called <em>identifiers</em>)
-in Lua can be any string of letters,
-digits, and underscores,
-not beginning with a digit.
-Identifiers are used to name variables, table fields, and labels.
-
-
-<p>
-The following <em>keywords</em> are reserved
-and cannot be used as names:
-
-
-<pre>
- and break do else elseif end
- false for function goto if in
- local nil not or repeat return
- then true until while
-</pre>
-
-<p>
-Lua is a case-sensitive language:
-<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
-are two different, valid names.
-As a convention, names starting with an underscore followed by
-uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>)
-are reserved for variables used by Lua.
-
-
-<p>
-The following strings denote other tokens:
-
-<pre>
- + - * / % ^ #
- == ~= <= >= < > =
- ( ) { } [ ] ::
- ; : , . .. ...
-</pre>
-
-<p>
-<em>Literal strings</em>
-can be delimited by matching single or double quotes,
-and can contain the following C-like escape sequences:
-'<code>\a</code>' (bell),
-'<code>\b</code>' (backspace),
-'<code>\f</code>' (form feed),
-'<code>\n</code>' (newline),
-'<code>\r</code>' (carriage return),
-'<code>\t</code>' (horizontal tab),
-'<code>\v</code>' (vertical tab),
-'<code>\\</code>' (backslash),
-'<code>\"</code>' (quotation mark [double quote]),
-and '<code>\'</code>' (apostrophe [single quote]).
-A backslash followed by a real newline
-results in a newline in the string.
-The escape sequence '<code>\z</code>' skips the following span
-of white-space characters,
-including line breaks;
-it is particularly useful to break and indent a long literal string
-into multiple lines without adding the newlines and spaces
-into the string contents.
-
-
-<p>
-A byte in a literal string can also be specified by its numerical value.
-This can be done with the escape sequence <code>\x<em>XX</em></code>,
-where <em>XX</em> is a sequence of exactly two hexadecimal digits,
-or with the escape sequence <code>\<em>ddd</em></code>,
-where <em>ddd</em> is a sequence of up to three decimal digits.
-(Note that if a decimal escape is to be followed by a digit,
-it must be expressed using exactly three digits.)
-Strings in Lua can contain any 8-bit value, including embedded zeros,
-which can be specified as '<code>\0</code>'.
-
-
-<p>
-Literal strings can also be defined using a long format
-enclosed by <em>long brackets</em>.
-We define an <em>opening long bracket of level <em>n</em></em> as an opening
-square bracket followed by <em>n</em> equal signs followed by another
-opening square bracket.
-So, an opening long bracket of level 0 is written as <code>[[</code>,
-an opening long bracket of level 1 is written as <code>[=[</code>,
-and so on.
-A <em>closing long bracket</em> is defined similarly;
-for instance, a closing long bracket of level 4 is written as <code>]====]</code>.
-A <em>long literal</em> starts with an opening long bracket of any level and
-ends at the first closing long bracket of the same level.
-It can contain any text except a closing bracket of the proper level.
-Literals in this bracketed form can run for several lines,
-do not interpret any escape sequences,
-and ignore long brackets of any other level.
-Any kind of end-of-line sequence
-(carriage return, newline, carriage return followed by newline,
-or newline followed by carriage return)
-is converted to a simple newline.
-
-
-<p>
-Any byte in a literal string not
-explicitly affected by the previous rules represents itself.
-However, Lua opens files for parsing in text mode,
-and the system file functions may have problems with
-some control characters.
-So, it is safer to represent
-non-text data as a quoted literal with
-explicit escape sequences for non-text characters.
-
-
-<p>
-For convenience,
-when the opening long bracket is immediately followed by a newline,
-the newline is not included in the string.
-As an example, in a system using ASCII
-(in which '<code>a</code>' is coded as 97,
-newline is coded as 10, and '<code>1</code>' is coded as 49),
-the five literal strings below denote the same string:
-
-<pre>
- a = 'alo\n123"'
- a = "alo\n123\""
- a = '\97lo\10\04923"'
- a = [[alo
- 123"]]
- a = [==[
- alo
- 123"]==]
-</pre>
-
-<p>
-A <em>numerical constant</em> can be written with an optional fractional part
-and an optional decimal exponent,
-marked by a letter '<code>e</code>' or '<code>E</code>'.
-Lua also accepts hexadecimal constants,
-which start with <code>0x</code> or <code>0X</code>.
-Hexadecimal constants also accept an optional fractional part
-plus an optional binary exponent,
-marked by a letter '<code>p</code>' or '<code>P</code>'.
-Examples of valid numerical constants are
-
-<pre>
- 3 3.0 3.1416 314.16e-2 0.31416E1
- 0xff 0x0.1E 0xA23p-4 0X1.921FB54442D18P+1
-</pre>
-
-<p>
-A <em>comment</em> starts with a double hyphen (<code>--</code>)
-anywhere outside a string.
-If the text immediately after <code>--</code> is not an opening long bracket,
-the comment is a <em>short comment</em>,
-which runs until the end of the line.
-Otherwise, it is a <em>long comment</em>,
-which runs until the corresponding closing long bracket.
-Long comments are frequently used to disable code temporarily.
-
-
-
-
-
-<h2>3.2 – <a name="3.2">Variables</a></h2>
-
-<p>
-Variables are places that store values.
-There are three kinds of variables in Lua:
-global variables, local variables, and table fields.
-
-
-<p>
-A single name can denote a global variable or a local variable
-(or a function's formal parameter,
-which is a particular kind of local variable):
-
-<pre>
- var ::= Name
-</pre><p>
-Name denotes identifiers, as defined in <a href="#3.1">§3.1</a>.
-
-
-<p>
-Any variable name is assumed to be global unless explicitly declared
-as a local (see <a href="#3.3.7">§3.3.7</a>).
-Local variables are <em>lexically scoped</em>:
-local variables can be freely accessed by functions
-defined inside their scope (see <a href="#3.5">§3.5</a>).
-
-
-<p>
-Before the first assignment to a variable, its value is <b>nil</b>.
-
-
-<p>
-Square brackets are used to index a table:
-
-<pre>
- var ::= prefixexp ‘<b>[</b>’ exp ‘<b>]</b>’
-</pre><p>
-The meaning of accesses to table fields can be changed via metatables.
-An access to an indexed variable <code>t[i]</code> is equivalent to
-a call <code>gettable_event(t,i)</code>.
-(See <a href="#2.4">§2.4</a> for a complete description of the
-<code>gettable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-The syntax <code>var.Name</code> is just syntactic sugar for
-<code>var["Name"]</code>:
-
-<pre>
- var ::= prefixexp ‘<b>.</b>’ Name
-</pre>
-
-<p>
-An access to a global variable <code>x</code>
-is equivalent to <code>_ENV.x</code>.
-Due to the way that chunks are compiled,
-<code>_ENV</code> is never a global name (see <a href="#2.2">§2.2</a>).
-
-
-
-
-
-<h2>3.3 – <a name="3.3">Statements</a></h2>
-
-<p>
-Lua supports an almost conventional set of statements,
-similar to those in Pascal or C.
-This set includes
-assignments, control structures, function calls,
-and variable declarations.
-
-
-
-<h3>3.3.1 – <a name="3.3.1">Blocks</a></h3>
-
-<p>
-A block is a list of statements,
-which are executed sequentially:
-
-<pre>
- block ::= {stat}
-</pre><p>
-Lua has <em>empty statements</em>
-that allow you to separate statements with semicolons,
-start a block with a semicolon
-or write two semicolons in sequence:
-
-<pre>
- stat ::= ‘<b>;</b>’
-</pre>
-
-<p>
-Function calls and assignments
-can start with an open parenthesis.
-This possibility leads to an ambiguity in Lua's grammar.
-Consider the following fragment:
-
-<pre>
- a = b + c
- (print or io.write)('done')
-</pre><p>
-The grammar could see it in two ways:
-
-<pre>
- a = b + c(print or io.write)('done')
-
- a = b + c; (print or io.write)('done')
-</pre><p>
-The current parser always sees such constructions
-in the first way,
-interpreting the open parenthesis
-as the start of the arguments to a call.
-To avoid this ambiguity,
-it is a good practice to always precede with a semicolon
-statements that start with a parenthesis:
-
-<pre>
- ;(print or io.write)('done')
-</pre>
-
-<p>
-A block can be explicitly delimited to produce a single statement:
-
-<pre>
- stat ::= <b>do</b> block <b>end</b>
-</pre><p>
-Explicit blocks are useful
-to control the scope of variable declarations.
-Explicit blocks are also sometimes used to
-add a <b>return</b> statement in the middle
-of another block (see <a href="#3.3.4">§3.3.4</a>).
-
-
-
-
-
-<h3>3.3.2 – <a name="3.3.2">Chunks</a></h3>
-
-<p>
-The unit of compilation of Lua is called a <em>chunk</em>.
-Syntactically,
-a chunk is simply a block:
-
-<pre>
- chunk ::= block
-</pre>
-
-<p>
-Lua handles a chunk as the body of an anonymous function
-with a variable number of arguments
-(see <a href="#3.4.10">§3.4.10</a>).
-As such, chunks can define local variables,
-receive arguments, and return values.
-Moreover, such anonymous function is compiled as in the
-scope of an external local variable called <code>_ENV</code> (see <a href="#2.2">§2.2</a>).
-The resulting function always has <code>_ENV</code> as its only upvalue,
-even if it does not use that variable.
-
-
-<p>
-A chunk can be stored in a file or in a string inside the host program.
-To execute a chunk,
-Lua first precompiles the chunk into instructions for a virtual machine,
-and then it executes the compiled code
-with an interpreter for the virtual machine.
-
-
-<p>
-Chunks can also be precompiled into binary form;
-see program <code>luac</code> for details.
-Programs in source and compiled forms are interchangeable;
-Lua automatically detects the file type and acts accordingly.
-
-
-
-
-
-
-<h3>3.3.3 – <a name="3.3.3">Assignment</a></h3>
-
-<p>
-Lua allows multiple assignments.
-Therefore, the syntax for assignment
-defines a list of variables on the left side
-and a list of expressions on the right side.
-The elements in both lists are separated by commas:
-
-<pre>
- stat ::= varlist ‘<b>=</b>’ explist
- varlist ::= var {‘<b>,</b>’ var}
- explist ::= exp {‘<b>,</b>’ exp}
-</pre><p>
-Expressions are discussed in <a href="#3.4">§3.4</a>.
-
-
-<p>
-Before the assignment,
-the list of values is <em>adjusted</em> to the length of
-the list of variables.
-If there are more values than needed,
-the excess values are thrown away.
-If there are fewer values than needed,
-the list is extended with as many <b>nil</b>'s as needed.
-If the list of expressions ends with a function call,
-then all values returned by that call enter the list of values,
-before the adjustment
-(except when the call is enclosed in parentheses; see <a href="#3.4">§3.4</a>).
-
-
-<p>
-The assignment statement first evaluates all its expressions
-and only then are the assignments performed.
-Thus the code
-
-<pre>
- i = 3
- i, a[i] = i+1, 20
-</pre><p>
-sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
-because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
-before it is assigned 4.
-Similarly, the line
-
-<pre>
- x, y = y, x
-</pre><p>
-exchanges the values of <code>x</code> and <code>y</code>,
-and
-
-<pre>
- x, y, z = y, z, x
-</pre><p>
-cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>.
-
-
-<p>
-The meaning of assignments to global variables
-and table fields can be changed via metatables.
-An assignment to an indexed variable <code>t[i] = val</code> is equivalent to
-<code>settable_event(t,i,val)</code>.
-(See <a href="#2.4">§2.4</a> for a complete description of the
-<code>settable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-An assignment to a global variable <code>x = val</code>
-is equivalent to the assignment
-<code>_ENV.x = val</code> (see <a href="#2.2">§2.2</a>).
-
-
-
-
-
-<h3>3.3.4 – <a name="3.3.4">Control Structures</a></h3><p>
-The control structures
-<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
-familiar syntax:
-
-
-
-
-<pre>
- stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
- stat ::= <b>repeat</b> block <b>until</b> exp
- stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
-</pre><p>
-Lua also has a <b>for</b> statement, in two flavors (see <a href="#3.3.5">§3.3.5</a>).
-
-
-<p>
-The condition expression of a
-control structure can return any value.
-Both <b>false</b> and <b>nil</b> are considered false.
-All values different from <b>nil</b> and <b>false</b> are considered true
-(in particular, the number 0 and the empty string are also true).
-
-
-<p>
-In the <b>repeat</b>–<b>until</b> loop,
-the inner block does not end at the <b>until</b> keyword,
-but only after the condition.
-So, the condition can refer to local variables
-declared inside the loop block.
-
-
-<p>
-The <b>goto</b> statement transfers the program control to a label.
-For syntactical reasons,
-labels in Lua are considered statements too:
-
-
-
-<pre>
- stat ::= <b>goto</b> Name
- stat ::= label
- label ::= ‘<b>::</b>’ Name ‘<b>::</b>’
-</pre>
-
-<p>
-A label is visible in the entire block where it is defined,
-except
-inside nested blocks where a label with the same name is defined and
-inside nested functions.
-A goto may jump to any visible label as long as it does not
-enter into the scope of a local variable.
-
-
-<p>
-Labels and empty statements are called <em>void statements</em>,
-as they perform no actions.
-
-
-<p>
-The <b>break</b> statement terminates the execution of a
-<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
-skipping to the next statement after the loop:
-
-
-<pre>
- stat ::= <b>break</b>
-</pre><p>
-A <b>break</b> ends the innermost enclosing loop.
-
-
-<p>
-The <b>return</b> statement is used to return values
-from a function or a chunk (which is a function in disguise).
-
-Functions can return more than one value,
-so the syntax for the <b>return</b> statement is
-
-<pre>
- stat ::= <b>return</b> [explist] [‘<b>;</b>’]
-</pre>
-
-<p>
-The <b>return</b> statement can only be written
-as the last statement of a block.
-If it is really necessary to <b>return</b> in the middle of a block,
-then an explicit inner block can be used,
-as in the idiom <code>do return end</code>,
-because now <b>return</b> is the last statement in its (inner) block.
-
-
-
-
-
-<h3>3.3.5 – <a name="3.3.5">For Statement</a></h3>
-
-<p>
-
-The <b>for</b> statement has two forms:
-one numeric and one generic.
-
-
-<p>
-The numeric <b>for</b> loop repeats a block of code while a
-control variable runs through an arithmetic progression.
-It has the following syntax:
-
-<pre>
- stat ::= <b>for</b> Name ‘<b>=</b>’ exp ‘<b>,</b>’ exp [‘<b>,</b>’ exp] <b>do</b> block <b>end</b>
-</pre><p>
-The <em>block</em> is repeated for <em>name</em> starting at the value of
-the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the
-third <em>exp</em>.
-More precisely, a <b>for</b> statement like
-
-<pre>
- for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
- do
- local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>)
- if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end
- while (<em>step</em> > 0 and <em>var</em> <= <em>limit</em>) or (<em>step</em> <= 0 and <em>var</em> >= <em>limit</em>) do
- local v = <em>var</em>
- <em>block</em>
- <em>var</em> = <em>var</em> + <em>step</em>
- end
- end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-All three control expressions are evaluated only once,
-before the loop starts.
-They must all result in numbers.
-</li>
-
-<li>
-<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables.
-The names shown here are for explanatory purposes only.
-</li>
-
-<li>
-If the third expression (the step) is absent,
-then a step of 1 is used.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variable <code>v</code> is local to the loop;
-you cannot use its value after the <b>for</b> ends or is broken.
-If you need this value,
-assign it to another variable before breaking or exiting the loop.
-</li>
-
-</ul>
-
-<p>
-The generic <b>for</b> statement works over functions,
-called <em>iterators</em>.
-On each iteration, the iterator function is called to produce a new value,
-stopping when this new value is <b>nil</b>.
-The generic <b>for</b> loop has the following syntax:
-
-<pre>
- stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
- namelist ::= Name {‘<b>,</b>’ Name}
-</pre><p>
-A <b>for</b> statement like
-
-<pre>
- for <em>var_1</em>, ···, <em>var_n</em> in <em>explist</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
- do
- local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em>
- while true do
- local <em>var_1</em>, ···, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>)
- if <em>var_1</em> == nil then break end
- <em>var</em> = <em>var_1</em>
- <em>block</em>
- end
- end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-<code><em>explist</em></code> is evaluated only once.
-Its results are an <em>iterator</em> function,
-a <em>state</em>,
-and an initial value for the first <em>iterator variable</em>.
-</li>
-
-<li>
-<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables.
-The names are here for explanatory purposes only.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variables <code><em>var_i</em></code> are local to the loop;
-you cannot use their values after the <b>for</b> ends.
-If you need these values,
-then assign them to other variables before breaking or exiting the loop.

-<h3>3.3.6 – <a name="3.3.6">Function Calls as Statements</a></h3><p>
-To allow possible side-effects,
-function calls can be executed as statements:
-
-<pre>
- stat ::= functioncall
-</pre><p>
-In this case, all returned values are thrown away.
-Function calls are explained in <a href="#3.4.9">§3.4.9</a>.
-
-
-
-
-
-<h3>3.3.7 – <a name="3.3.7">Local Declarations</a></h3><p>
-Local variables can be declared anywhere inside a block.
-The declaration can include an initial assignment:
-
-<pre>
- stat ::= <b>local</b> namelist [‘<b>=</b>’ explist]
-</pre><p>
-If present, an initial assignment has the same semantics
-of a multiple assignment (see <a href="#3.3.3">§3.3.3</a>).
-Otherwise, all variables are initialized with <b>nil</b>.
-
-
-<p>
-A chunk is also a block (see <a href="#3.3.2">§3.3.2</a>),
-and so local variables can be declared in a chunk outside any explicit block.
-
-
-<p>
-The visibility rules for local variables are explained in <a href="#3.5">§3.5</a>.
-
-
-
-
-
-
-
-<h2>3.4 – <a name="3.4">Expressions</a></h2>
-
-<p>
-The basic expressions in Lua are the following:
-
-<pre>
- exp ::= prefixexp
- exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
- exp ::= Number
- exp ::= String
- exp ::= functiondef
- exp ::= tableconstructor
- exp ::= ‘<b>...</b>’
- exp ::= exp binop exp
- exp ::= unop exp
- prefixexp ::= var | functioncall | ‘<b>(</b>’ exp ‘<b>)</b>’
-</pre>
-
-<p>
-Numbers and literal strings are explained in <a href="#3.1">§3.1</a>;
-variables are explained in <a href="#3.2">§3.2</a>;
-function definitions are explained in <a href="#3.4.10">§3.4.10</a>;
-function calls are explained in <a href="#3.4.9">§3.4.9</a>;
-table constructors are explained in <a href="#3.4.8">§3.4.8</a>.
-Vararg expressions,
-denoted by three dots ('<code>...</code>'), can only be used when
-directly inside a vararg function;
-they are explained in <a href="#3.4.10">§3.4.10</a>.
-
-
-<p>
-Binary operators comprise arithmetic operators (see <a href="#3.4.1">§3.4.1</a>),
-relational operators (see <a href="#3.4.3">§3.4.3</a>), logical operators (see <a href="#3.4.4">§3.4.4</a>),
-and the concatenation operator (see <a href="#3.4.5">§3.4.5</a>).
-Unary operators comprise the unary minus (see <a href="#3.4.1">§3.4.1</a>),
-the unary <b>not</b> (see <a href="#3.4.4">§3.4.4</a>),
-and the unary <em>length operator</em> (see <a href="#3.4.6">§3.4.6</a>).
-
-
-<p>
-Both function calls and vararg expressions can result in multiple values.
-If a function call is used as a statement (see <a href="#3.3.6">§3.3.6</a>),
-then its return list is adjusted to zero elements,
-thus discarding all returned values.
-If an expression is used as the last (or the only) element
-of a list of expressions,
-then no adjustment is made
-(unless the expression is enclosed in parentheses).
-In all other contexts,
-Lua adjusts the result list to one element,
-either discarding all values except the first one
-or adding a single <b>nil</b> if there are no values.
-
-
-<p>
-Here are some examples:
-
-<pre>
- f() -- adjusted to 0 results
- g(f(), x) -- f() is adjusted to 1 result
- g(x, f()) -- g gets x plus all results from f()
- a,b,c = f(), x -- f() is adjusted to 1 result (c gets nil)
- a,b = ... -- a gets the first vararg parameter, b gets
- -- the second (both a and b can get nil if there
- -- is no corresponding vararg parameter)
-
- a,b,c = x, f() -- f() is adjusted to 2 results
- a,b,c = f() -- f() is adjusted to 3 results
- return f() -- returns all results from f()
- return ... -- returns all received vararg parameters
- return x,y,f() -- returns x, y, and all results from f()
- {f()} -- creates a list with all results from f()
- {...} -- creates a list with all vararg parameters
- {f(), nil} -- f() is adjusted to 1 result
-</pre>
-
-<p>
-Any expression enclosed in parentheses always results in only one value.
-Thus,
-<code>(f(x,y,z))</code> is always a single value,
-even if <code>f</code> returns several values.
-(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code>
-or <b>nil</b> if <code>f</code> does not return any values.)
-
-
-
-<h3>3.4.1 – <a name="3.4.1">Arithmetic Operators</a></h3><p>
-Lua supports the usual arithmetic operators:
-the binary <code>+</code> (addition),
-<code>-</code> (subtraction), <code>*</code> (multiplication),
-<code>/</code> (division), <code>%</code> (modulo), and <code>^</code> (exponentiation);
-and unary <code>-</code> (mathematical negation).
-If the operands are numbers, or strings that can be converted to
-numbers (see <a href="#3.4.2">§3.4.2</a>),
-then all operations have the usual meaning.
-Exponentiation works for any exponent.
-For instance, <code>x^(-0.5)</code> computes the inverse of the square root of <code>x</code>.
-Modulo is defined as
-
-<pre>
- a % b == a - math.floor(a/b)*b
-</pre><p>
-That is, it is the remainder of a division that rounds
-the quotient towards minus infinity.
-
-
-
-
-
-<h3>3.4.2 – <a name="3.4.2">Coercion</a></h3>
-
-<p>
-Lua provides automatic conversion between
-string and number values at run time.
-Any arithmetic operation applied to a string tries to convert
-this string to a number, following the rules of the Lua lexer.
-(The string may have leading and trailing spaces and a sign.)
-Conversely, whenever a number is used where a string is expected,
-the number is converted to a string, in a reasonable format.
-For complete control over how numbers are converted to strings,
-use the <code>format</code> function from the string library
-(see <a href="#pdf-string.format"><code>string.format</code></a>).
-
-
-
-
-
-<h3>3.4.3 – <a name="3.4.3">Relational Operators</a></h3><p>
-The relational operators in Lua are
-
-<pre>
- == ~= < > <= >=
-</pre><p>
-These operators always result in <b>false</b> or <b>true</b>.
-
-
-<p>
-Equality (<code>==</code>) first compares the type of its operands.
-If the types are different, then the result is <b>false</b>.
-Otherwise, the values of the operands are compared.
-Numbers and strings are compared in the usual way.
-Tables, userdata, and threads
-are compared by reference:
-two objects are considered equal only if they are the same object.
-Every time you create a new object
-(a table, userdata, or thread),
-this new object is different from any previously existing object.
-Closures with the same reference are always equal.
-Closures with any detectable difference
-(different behavior, different definition) are always different.
-
-
-<p>
-You can change the way that Lua compares tables and userdata
-by using the "eq" metamethod (see <a href="#2.4">§2.4</a>).
-
-
-<p>
-The conversion rules of <a href="#3.4.2">§3.4.2</a>
-do not apply to equality comparisons.
-Thus, <code>"0"==0</code> evaluates to <b>false</b>,
-and <code>t[0]</code> and <code>t["0"]</code> denote different
-entries in a table.
-
-
-<p>
-The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
-
-
-<p>
-The order operators work as follows.
-If both arguments are numbers, then they are compared as such.
-Otherwise, if both arguments are strings,
-then their values are compared according to the current locale.
-Otherwise, Lua tries to call the "lt" or the "le"
-metamethod (see <a href="#2.4">§2.4</a>).
-A comparison <code>a > b</code> is translated to <code>b < a</code>
-and <code>a >= b</code> is translated to <code>b <= a</code>.
-
-
-
-
-
-<h3>3.4.4 – <a name="3.4.4">Logical Operators</a></h3><p>
-The logical operators in Lua are
-<b>and</b>, <b>or</b>, and <b>not</b>.
-Like the control structures (see <a href="#3.3.4">§3.3.4</a>),
-all logical operators consider both <b>false</b> and <b>nil</b> as false
-and anything else as true.
-
-
-<p>
-The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
-The conjunction operator <b>and</b> returns its first argument
-if this value is <b>false</b> or <b>nil</b>;
-otherwise, <b>and</b> returns its second argument.
-The disjunction operator <b>or</b> returns its first argument
-if this value is different from <b>nil</b> and <b>false</b>;
-otherwise, <b>or</b> returns its second argument.
-Both <b>and</b> and <b>or</b> use short-cut evaluation;
-that is,
-the second operand is evaluated only if necessary.
-Here are some examples:
-
-<pre>
- 10 or 20 --> 10
- 10 or error() --> 10
- nil or "a" --> "a"
- nil and 10 --> nil
- false and error() --> false
- false and nil --> false
- false or nil --> nil
- 10 and 20 --> 20
-</pre><p>
-(In this manual,
-<code>--></code> indicates the result of the preceding expression.)
-
-
-
-
-
-<h3>3.4.5 – <a name="3.4.5">Concatenation</a></h3><p>
-The string concatenation operator in Lua is
-denoted by two dots ('<code>..</code>').
-If both operands are strings or numbers, then they are converted to
-strings according to the rules mentioned in <a href="#3.4.2">§3.4.2</a>.
-Otherwise, the <code>__concat</code> metamethod is called (see <a href="#2.4">§2.4</a>).
-
-
-
-
-
-<h3>3.4.6 – <a name="3.4.6">The Length Operator</a></h3>
-
-<p>
-The length operator is denoted by the unary prefix operator <code>#</code>.
-The length of a string is its number of bytes
-(that is, the usual meaning of string length when each
-character is one byte).
-
-
-<p>
-A program can modify the behavior of the length operator for
-any value but strings through the <code>__len</code> metamethod (see <a href="#2.4">§2.4</a>).
-
-
-<p>
-Unless a <code>__len</code> metamethod is given,
-the length of a table <code>t</code> is only defined if the
-table is a <em>sequence</em>,
-that is,
-the set of its positive numeric keys is equal to <em>{1..n}</em>
-for some non-negative integer <em>n</em>.
-In that case, <em>n</em> is its length.
-Note that a table like
-
-<pre>
- {10, 20, nil, 40}
-</pre><p>
-is not a sequence, because it has the key <code>4</code>
-but does not have the key <code>3</code>.
-(So, there is no <em>n</em> such that the set <em>{1..n}</em> is equal
-to the set of positive numeric keys of that table.)
-Note, however, that non-numeric keys do not interfere
-with whether a table is a sequence.
-
-
-
-
-
-<h3>3.4.7 – <a name="3.4.7">Precedence</a></h3><p>
-Operator precedence in Lua follows the table below,
-from lower to higher priority:
-
-<pre>
- or
- and
- < > <= >= ~= ==
- ..
- + -
- * / %
- not # - (unary)
- ^
-</pre><p>
-As usual,
-you can use parentheses to change the precedences of an expression.
-The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
-operators are right associative.
-All other binary operators are left associative.
-
-
-
-
-
-<h3>3.4.8 – <a name="3.4.8">Table Constructors</a></h3><p>
-Table constructors are expressions that create tables.
-Every time a constructor is evaluated, a new table is created.
-A constructor can be used to create an empty table
-or to create a table and initialize some of its fields.
-The general syntax for constructors is
-
-<pre>
- tableconstructor ::= ‘<b>{</b>’ [fieldlist] ‘<b>}</b>’
- fieldlist ::= field {fieldsep field} [fieldsep]
- field ::= ‘<b>[</b>’ exp ‘<b>]</b>’ ‘<b>=</b>’ exp | Name ‘<b>=</b>’ exp | exp
- fieldsep ::= ‘<b>,</b>’ | ‘<b>;</b>’
-</pre>
-
-<p>
-Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
-with key <code>exp1</code> and value <code>exp2</code>.
-A field of the form <code>name = exp</code> is equivalent to
-<code>["name"] = exp</code>.
-Finally, fields of the form <code>exp</code> are equivalent to
-<code>[i] = exp</code>, where <code>i</code> are consecutive numerical integers,
-starting with 1.
-Fields in the other formats do not affect this counting.
-For example,
-
-<pre>
- a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
-</pre><p>
-is equivalent to
-
-<pre>
- do
- local t = {}
- t[f(1)] = g
- t[1] = "x" -- 1st exp
- t[2] = "y" -- 2nd exp
- t.x = 1 -- t["x"] = 1
- t[3] = f(x) -- 3rd exp
- t[30] = 23
- t[4] = 45 -- 4th exp
- a = t
- end
-</pre>
-
-<p>
-If the last field in the list has the form <code>exp</code>
-and the expression is a function call or a vararg expression,
-then all values returned by this expression enter the list consecutively
-(see <a href="#3.4.9">§3.4.9</a>).
-
-
-<p>
-The field list can have an optional trailing separator,
-as a convenience for machine-generated code.
-
-
-
-
-
-<h3>3.4.9 – <a name="3.4.9">Function Calls</a></h3><p>
-A function call in Lua has the following syntax:
-
-<pre>
- functioncall ::= prefixexp args
-</pre><p>
-In a function call,
-first prefixexp and args are evaluated.
-If the value of prefixexp has type <em>function</em>,
-then this function is called
-with the given arguments.
-Otherwise, the prefixexp "call" metamethod is called,
-having as first parameter the value of prefixexp,
-followed by the original call arguments
-(see <a href="#2.4">§2.4</a>).
-
-
-<p>
-The form
-
-<pre>
- functioncall ::= prefixexp ‘<b>:</b>’ Name args
-</pre><p>
-can be used to call "methods".
-A call <code>v:name(<em>args</em>)</code>
-is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
-except that <code>v</code> is evaluated only once.
-
-
-<p>
-Arguments have the following syntax:
-
-<pre>
- args ::= ‘<b>(</b>’ [explist] ‘<b>)</b>’
- args ::= tableconstructor
- args ::= String
-</pre><p>
-All argument expressions are evaluated before the call.
-A call of the form <code>f{<em>fields</em>}</code> is
-syntactic sugar for <code>f({<em>fields</em>})</code>;
-that is, the argument list is a single new table.
-A call of the form <code>f'<em>string</em>'</code>
-(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
-is syntactic sugar for <code>f('<em>string</em>')</code>;
-that is, the argument list is a single literal string.
-
-
-<p>
-A call of the form <code>return <em>functioncall</em></code> is called
-a <em>tail call</em>.
-Lua implements <em>proper tail calls</em>
-(or <em>proper tail recursion</em>):
-in a tail call,
-the called function reuses the stack entry of the calling function.
-Therefore, there is no limit on the number of nested tail calls that
-a program can execute.
-However, a tail call erases any debug information about the
-calling function.
-Note that a tail call only happens with a particular syntax,
-where the <b>return</b> has one single function call as argument;
-this syntax makes the calling function return exactly
-the returns of the called function.
-So, none of the following examples are tail calls:
-
-<pre>
- return (f(x)) -- results adjusted to 1
- return 2 * f(x)
- return x, f(x) -- additional results
- f(x); return -- results discarded
- return x or f(x) -- results adjusted to 1
-</pre>
-
-
-
-
-<h3>3.4.10 – <a name="3.4.10">Function Definitions</a></h3>
-
-<p>
-The syntax for function definition is
-
-<pre>
- functiondef ::= <b>function</b> funcbody
- funcbody ::= ‘<b>(</b>’ [parlist] ‘<b>)</b>’ block <b>end</b>
-</pre>
-
-<p>
-The following syntactic sugar simplifies function definitions:
-
-<pre>
- stat ::= <b>function</b> funcname funcbody
- stat ::= <b>local</b> <b>function</b> Name funcbody
- funcname ::= Name {‘<b>.</b>’ Name} [‘<b>:</b>’ Name]
-</pre><p>
-The statement
-
-<pre>
- function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
- f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
- function t.a.b.c.f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
- t.a.b.c.f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
- local function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
- local f; f = function () <em>body</em> end
-</pre><p>
-not to
-
-<pre>
- local f = function () <em>body</em> end
-</pre><p>
-(This only makes a difference when the body of the function
-contains references to <code>f</code>.)
-
-
-<p>
-A function definition is an executable expression,
-whose value has type <em>function</em>.
-When Lua precompiles a chunk,
-all its function bodies are precompiled too.
-Then, whenever Lua executes the function definition,
-the function is <em>instantiated</em> (or <em>closed</em>).
-This function instance (or <em>closure</em>)
-is the final value of the expression.
-
-
-<p>
-Parameters act as local variables that are
-initialized with the argument values:
-
-<pre>
- parlist ::= namelist [‘<b>,</b>’ ‘<b>...</b>’] | ‘<b>...</b>’
-</pre><p>
-When a function is called,
-the list of arguments is adjusted to
-the length of the list of parameters,
-unless the function is a <em>vararg function</em>,
-which is indicated by three dots ('<code>...</code>')
-at the end of its parameter list.
-A vararg function does not adjust its argument list;
-instead, it collects all extra arguments and supplies them
-to the function through a <em>vararg expression</em>,
-which is also written as three dots.
-The value of this expression is a list of all actual extra arguments,
-similar to a function with multiple results.
-If a vararg expression is used inside another expression
-or in the middle of a list of expressions,
-then its return list is adjusted to one element.
-If the expression is used as the last element of a list of expressions,
-then no adjustment is made
-(unless that last expression is enclosed in parentheses).
-
-
-<p>
-As an example, consider the following definitions:
-
-<pre>
- function f(a, b) end
- function g(a, b, ...) end
- function r() return 1,2,3 end
-</pre><p>
-Then, we have the following mapping from arguments to parameters and
-to the vararg expression:
-
-<pre>
- CALL PARAMETERS
-
- f(3) a=3, b=nil
- f(3, 4) a=3, b=4
- f(3, 4, 5) a=3, b=4
- f(r(), 10) a=1, b=10
- f(r()) a=1, b=2
-
- g(3) a=3, b=nil, ... --> (nothing)
- g(3, 4) a=3, b=4, ... --> (nothing)
- g(3, 4, 5, 8) a=3, b=4, ... --> 5 8
- g(5, r()) a=5, b=1, ... --> 2 3
-</pre>
-
-<p>
-Results are returned using the <b>return</b> statement (see <a href="#3.3.4">§3.3.4</a>).
-If control reaches the end of a function
-without encountering a <b>return</b> statement,
-then the function returns with no results.
-
-
-<p>
-
-There is a system-dependent limit on the number of values
-that a function may return.
-This limit is guaranteed to be larger than 1000.
-
-
-<p>
-The <em>colon</em> syntax
-is used for defining <em>methods</em>,
-that is, functions that have an implicit extra parameter <code>self</code>.
-Thus, the statement
-
-<pre>
- function t.a.b.c:f (<em>params</em>) <em>body</em> end
-</pre><p>
-is syntactic sugar for
-
-<pre>
- t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
-</pre>
-
-
-
-
-
-
-<h2>3.5 – <a name="3.5">Visibility Rules</a></h2>
-
-<p>
-
-Lua is a lexically scoped language.
-The scope of a local variable begins at the first statement after
-its declaration and lasts until the last non-void statement
-of the innermost block that includes the declaration.
-Consider the following example:
-
-<pre>
- x = 10 -- global variable
- do -- new block
- local x = x -- new 'x', with value 10
- print(x) --> 10
- x = x+1
- do -- another block
- local x = x+1 -- another 'x'
- print(x) --> 12
- end
- print(x) --> 11
- end
- print(x) --> 10 (the global one)
-</pre>
-
-<p>
-Notice that, in a declaration like <code>local x = x</code>,
-the new <code>x</code> being declared is not in scope yet,
-and so the second <code>x</code> refers to the outside variable.
-
-
-<p>
-Because of the lexical scoping rules,
-local variables can be freely accessed by functions
-defined inside their scope.
-A local variable used by an inner function is called
-an <em>upvalue</em>, or <em>external local variable</em>,
-inside the inner function.
-
-
-<p>
-Notice that each execution of a <b>local</b> statement
-defines new local variables.
-Consider the following example:
-
-<pre>
- a = {}
- local x = 20
- for i=1,10 do
- local y = 0
- a[i] = function () y=y+1; return x+y end
- end
-</pre><p>
-The loop creates ten closures
-(that is, ten instances of the anonymous function).
-Each of these closures uses a different <code>y</code> variable,
-while all of them share the same <code>x</code>.
-
-
-
-
-
-<h1>4 – <a name="4">The Application Program Interface</a></h1>
-
-<p>
-
-This section describes the C API for Lua, that is,
-the set of C functions available to the host program to communicate
-with Lua.
-All API functions and related types and constants
-are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
-
-
-<p>
-Even when we use the term "function",
-any facility in the API may be provided as a macro instead.
-Except where stated otherwise,
-all such macros use each of their arguments exactly once
-(except for the first argument, which is always a Lua state),
-and so do not generate any hidden side-effects.
-
-
-<p>
-As in most C libraries,
-the Lua API functions do not check their arguments for validity or consistency.
-However, you can change this behavior by compiling Lua
-with the macro <a name="pdf-LUA_USE_APICHECK"><code>LUA_USE_APICHECK</code></a> defined.
-
-
-
-<h2>4.1 – <a name="4.1">The Stack</a></h2>
-
-<p>
-Lua uses a <em>virtual stack</em> to pass values to and from C.
-Each element in this stack represents a Lua value
-(<b>nil</b>, number, string, etc.).
-
-
-<p>
-Whenever Lua calls C, the called function gets a new stack,
-which is independent of previous stacks and of stacks of
-C functions that are still active.
-This stack initially contains any arguments to the C function
-and it is where the C function pushes its results
-to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
-
-
-<p>
-For convenience,
-most query operations in the API do not follow a strict stack discipline.
-Instead, they can refer to any element in the stack
-by using an <em>index</em>:
-A positive index represents an absolute stack position
-(starting at 1);
-a negative index represents an offset relative to the top of the stack.
-More specifically, if the stack has <em>n</em> elements,
-then index 1 represents the first element
-(that is, the element that was pushed onto the stack first)
-and
-index <em>n</em> represents the last element;
-index -1 also represents the last element
-(that is, the element at the top)
-and index <em>-n</em> represents the first element.
-
-
-
-
-
-<h2>4.2 – <a name="4.2">Stack Size</a></h2>
-
-<p>
-When you interact with the Lua API,
-you are responsible for ensuring consistency.
-In particular,
-<em>you are responsible for controlling stack overflow</em>.
-You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
-to ensure that the stack has extra slots when pushing new elements.
-
-
-<p>
-Whenever Lua calls C,
-it ensures that the stack has at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> extra slots.
-<code>LUA_MINSTACK</code> is defined as 20,
-so that usually you do not have to worry about stack space
-unless your code has loops pushing elements onto the stack.
-
-
-<p>
-When you call a Lua function
-without a fixed number of results (see <a href="#lua_call"><code>lua_call</code></a>),
-Lua ensures that the stack has enough size for all results,
-but it does not ensure any extra space.
-So, before pushing anything in the stack after such a call
-you should use <a href="#lua_checkstack"><code>lua_checkstack</code></a>.

-
-<h2>4.3 – <a name="4.3">Valid and Acceptable Indices</a></h2>
-
-<p>
-Any function in the API that receives stack indices
-works only with <em>valid indices</em> or <em>acceptable indices</em>.
-
-
-<p>
-A <em>valid index</em> is an index that refers to a
-real position within the stack, that is,
-its position lies between 1 and the stack top
-(<code>1 ≤ abs(index) ≤ top</code>).
-
-Usually, functions that can modify the value at an index
-require valid indices.
-
-
-<p>
-Unless otherwise noted,
-any function that accepts valid indices also accepts <em>pseudo-indices</em>,
-which represent some Lua values that are accessible to C code
-but which are not in the stack.
-Pseudo-indices are used to access the registry
-and the upvalues of a C function (see <a href="#4.4">§4.4</a>).
-
-
-<p>
-Functions that do not need a specific stack position,
-but only a value in the stack (e.g., query functions),
-can be called with acceptable indices.
-An <em>acceptable index</em> can be any valid index,
-including the pseudo-indices,
-but it also can be any positive index after the stack top
-within the space allocated for the stack,
-that is, indices up to the stack size.
-(Note that 0 is never an acceptable index.)
-Except when noted otherwise,
-functions in the API work with acceptable indices.
-
-
-<p>
-Acceptable indices serve to avoid extra tests
-against the stack top when querying the stack.
-For instance, a C function can query its third argument
-without the need to first check whether there is a third argument,
-that is, without the need to check whether 3 is a valid index.
-
-
-<p>
-For functions that can be called with acceptable indices,
-any non-valid index is treated as if it
-contains a value of a virtual type <a name="pdf-LUA_TNONE"><code>LUA_TNONE</code></a>,
-which behaves like a nil value.
-
-
-
-
-
-<h2>4.4 – <a name="4.4">C Closures</a></h2>
-
-<p>
-When a C function is created,
-it is possible to associate some values with it,
-thus creating a <em>C closure</em>
-(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>);
-these values are called <em>upvalues</em> and are
-accessible to the function whenever it is called.
-
-
-<p>
-Whenever a C function is called,
-its upvalues are located at specific pseudo-indices.
-These pseudo-indices are produced by the macro
-<a href="#lua_upvalueindex"><code>lua_upvalueindex</code></a>.
-The first value associated with a function is at position
-<code>lua_upvalueindex(1)</code>, and so on.
-Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
-where <em>n</em> is greater than the number of upvalues of the
-current function (but not greater than 256),
-produces an acceptable but invalid index.
-
-
-
-
-
-<h2>4.5 – <a name="4.5">Registry</a></h2>
-
-<p>
-Lua provides a <em>registry</em>,
-a predefined table that can be used by any C code to
-store whatever Lua values it needs to store.
-The registry table is always located at pseudo-index
-<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>,
-which is a valid index.
-Any C library can store data into this table,
-but it should take care to choose keys
-that are different from those used
-by other libraries, to avoid collisions.
-Typically, you should use as key a string containing your library name,
-or a light userdata with the address of a C object in your code,
-or any Lua object created by your code.
-As with global names,
-string keys starting with an underscore followed by
-uppercase letters are reserved for Lua.
-
-
-<p>
-The integer keys in the registry are used by the reference mechanism,
-implemented by the auxiliary library,
-and by some predefined values.
-Therefore, integer keys should not be used for other purposes.
-
-
-<p>
-When you create a new Lua state,
-its registry comes with some predefined values.
-These predefined values are indexed with integer keys
-defined as constants in <code>lua.h</code>.
-The following constants are defined:
-
-<ul>
-<li><b><a name="pdf-LUA_RIDX_MAINTHREAD"><code>LUA_RIDX_MAINTHREAD</code></a>: </b> At this index the registry has
-the main thread of the state.
-(The main thread is the one created together with the state.)
-</li>
-
-<li><b><a name="pdf-LUA_RIDX_GLOBALS"><code>LUA_RIDX_GLOBALS</code></a>: </b> At this index the registry has
-the global environment.
-</li>
-</ul>
-
-
-
-
-<h2>4.6 – <a name="4.6">Error Handling in C</a></h2>
-
-<p>
-Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
-(You can also choose to use exceptions if you compile Lua as C++;
-search for <code>LUAI_THROW</code> in the source code.)
-When Lua faces any error
-(such as a memory allocation error, type errors, syntax errors,
-and runtime errors)
-it <em>raises</em> an error;
-that is, it does a long jump.
-A <em>protected environment</em> uses <code>setjmp</code>
-to set a recovery point;
-any error jumps to the most recent active recovery point.
-
-
-<p>
-If an error happens outside any protected environment,
-Lua calls a <em>panic function</em> (see <a href="#lua_atpanic"><code>lua_atpanic</code></a>)
-and then calls <code>abort</code>,
-thus exiting the host application.
-Your panic function can avoid this exit by
-never returning
-(e.g., doing a long jump to your own recovery point outside Lua).
-
-
-<p>
-The panic function runs as if it were a message handler (see <a href="#2.3">§2.3</a>);
-in particular, the error message is at the top of the stack.
-However, there is no guarantees about stack space.
-To push anything on the stack,
-the panic function should first check the available space (see <a href="#4.2">§4.2</a>).
-
-
-<p>
-Most functions in the API can throw an error,
-for instance due to a memory allocation error.
-The documentation for each function indicates whether
-it can throw errors.
-
-
-<p>
-Inside a C function you can throw an error by calling <a href="#lua_error"><code>lua_error</code></a>.
-
-
-
-
-
-<h2>4.7 – <a name="4.7">Handling Yields in C</a></h2>
-
-<p>
-Internally, Lua uses the C <code>longjmp</code> facility to yield a coroutine.
-Therefore, if a function <code>foo</code> calls an API function
-and this API function yields
-(directly or indirectly by calling another function that yields),
-Lua cannot return to <code>foo</code> any more,
-because the <code>longjmp</code> removes its frame from the C stack.
-
-
-<p>
-To avoid this kind of problem,
-Lua raises an error whenever it tries to yield across an API call,
-except for three functions:
-<a href="#lua_yieldk"><code>lua_yieldk</code></a>, <a href="#lua_callk"><code>lua_callk</code></a>, and <a href="#lua_pcallk"><code>lua_pcallk</code></a>.
-All those functions receive a <em>continuation function</em>
-(as a parameter called <code>k</code>) to continue execution after a yield.
-
-
-<p>
-We need to set some terminology to explain continuations.
-We have a C function called from Lua which we will call
-the <em>original function</em>.
-This original function then calls one of those three functions in the C API,
-which we will call the <em>callee function</em>,
-that then yields the current thread.
-(This can happen when the callee function is <a href="#lua_yieldk"><code>lua_yieldk</code></a>,
-or when the callee function is either <a href="#lua_callk"><code>lua_callk</code></a> or <a href="#lua_pcallk"><code>lua_pcallk</code></a>
-and the function called by them yields.)
-
-
-<p>
-Suppose the running thread yields while executing the callee function.
-After the thread resumes,
-it eventually will finish running the callee function.
-However,
-the callee function cannot return to the original function,
-because its frame in the C stack was destroyed by the yield.
-Instead, Lua calls a <em>continuation function</em>,
-which was given as an argument to the callee function.
-As the name implies,
-the continuation function should continue the task
-of the original function.
-
-
-<p>
-Lua treats the continuation function as if it were the original function.
-The continuation function receives the same Lua stack
-from the original function,
-in the same state it would be if the callee function had returned.
-(For instance,
-after a <a href="#lua_callk"><code>lua_callk</code></a> the function and its arguments are
-removed from the stack and replaced by the results from the call.)
-It also has the same upvalues.
-Whatever it returns is handled by Lua as if it were the return
-of the original function.
-
-
-<p>
-The only difference in the Lua state between the original function
-and its continuation is the result of a call to <a href="#lua_getctx"><code>lua_getctx</code></a>.
-
-
-
-
-
-<h2>4.8 – <a name="4.8">Functions and Types</a></h2>
-
-<p>
-Here we list all functions and types from the C API in
-alphabetical order.
-Each function has an indicator like this:
-<span class="apii">[-o, +p, <em>x</em>]</span>
-
-
-<p>
-The first field, <code>o</code>,
-is how many elements the function pops from the stack.
-The second field, <code>p</code>,
-is how many elements the function pushes onto the stack.
-(Any function always pushes its results after popping its arguments.)
-A field in the form <code>x|y</code> means the function can push (or pop)
-<code>x</code> or <code>y</code> elements,
-depending on the situation;
-an interrogation mark '<code>?</code>' means that
-we cannot know how many elements the function pops/pushes
-by looking only at its arguments
-(e.g., they may depend on what is on the stack).
-The third field, <code>x</code>,
-tells whether the function may throw errors:
-'<code>-</code>' means the function never throws any error;
-'<code>e</code>' means the function may throw errors;
-'<code>v</code>' means the function may throw an error on purpose.

-<pre>int lua_absindex (lua_State *L, int idx);</pre>

-<pre>typedef void * (*lua_Alloc) (void *ud,
- void *ptr,

-
-<p>
-The type of the memory-allocation function used by Lua states.
-The allocator function must provide a
-functionality similar to <code>realloc</code>,
-but not exactly the same.
-Its arguments are
-<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
-<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
-<code>osize</code>, the original size of the block or some code about what
-is being allocated;
-<code>nsize</code>, the new size of the block.
-
-
-<p>
-When <code>ptr</code> is not <code>NULL</code>,
-<code>osize</code> is the size of the block pointed by <code>ptr</code>,
-that is, the size given when it was allocated or reallocated.
-
-
-<p>
-When <code>ptr</code> is <code>NULL</code>,
-<code>osize</code> encodes the kind of object that Lua is allocating.
-<code>osize</code> is any of
-<a href="#pdf-LUA_TSTRING"><code>LUA_TSTRING</code></a>, <a href="#pdf-LUA_TTABLE"><code>LUA_TTABLE</code></a>, <a href="#pdf-LUA_TFUNCTION"><code>LUA_TFUNCTION</code></a>,
-<a href="#pdf-LUA_TUSERDATA"><code>LUA_TUSERDATA</code></a>, or <a href="#pdf-LUA_TTHREAD"><code>LUA_TTHREAD</code></a> when (and only when)
-Lua is creating a new object of that type.
-When <code>osize</code> is some other value,
-Lua is allocating memory for something else.
-
-
-<p>
-Lua assumes the following behavior from the allocator function:
-
-
-<p>
-When <code>nsize</code> is zero,
-the allocator should behave like <code>free</code>
-and return <code>NULL</code>.
-
-
-<p>
-When <code>nsize</code> is not zero,
-the allocator should behave like <code>realloc</code>.
-The allocator returns <code>NULL</code>
-if and only if it cannot fulfill the request.
-Lua assumes that the allocator never fails when
-<code>osize >= nsize</code>.
-
-
-<p>
-Here is a simple implementation for the allocator function.
-It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
-
-<pre>
- static void *l_alloc (void *ud, void *ptr, size_t osize,
- size_t nsize) {
- (void)ud; (void)osize; /* not used */
- if (nsize == 0) {
- free(ptr);
- return NULL;
- }
- else
- return realloc(ptr, nsize);
- }
-</pre><p>
-Note that Standard C ensures
-that <code>free(NULL)</code> has no effect and that
-<code>realloc(NULL, size)</code> is equivalent to <code>malloc(size)</code>.
-This code assumes that <code>realloc</code> does not fail when shrinking a block.
-(Although Standard C does not ensure this behavior,
-it seems to be a safe assumption.)

-<pre>void lua_call (lua_State *L, int nargs, int nresults);</pre>
-
-<p>
-Calls a function.
-
-
-<p>
-To call a function you must use the following protocol:
-first, the function to be called is pushed onto the stack;
-then, the arguments to the function are pushed
-in direct order;
-that is, the first argument is pushed first.
-Finally you call <a href="#lua_call"><code>lua_call</code></a>;
-<code>nargs</code> is the number of arguments that you pushed onto the stack.
-All arguments and the function value are popped from the stack
-when the function is called.
-The function results are pushed onto the stack when the function returns.
-The number of results is adjusted to <code>nresults</code>,
-unless <code>nresults</code> is <a name="pdf-LUA_MULTRET"><code>LUA_MULTRET</code></a>.
-In this case, all results from the function are pushed.
-Lua takes care that the returned values fit into the stack space.
-The function results are pushed onto the stack in direct order
-(the first result is pushed first),
-so that after the call the last result is on the top of the stack.
-
-
-<p>
-Any error inside the called function is propagated upwards
-(with a <code>longjmp</code>).
-
-
-<p>
-The following example shows how the host program can do the
-equivalent to this Lua code:
-
-<pre>
- a = f("how", t.x, 14)
-</pre><p>
-Here it is in C:
-
-<pre>
- lua_getglobal(L, "f"); /* function to be called */
- lua_pushstring(L, "how"); /* 1st argument */
- lua_getglobal(L, "t"); /* table to be indexed */
- lua_getfield(L, -1, "x"); /* push result of t.x (2nd arg) */
- lua_remove(L, -2); /* remove 't' from the stack */
- lua_pushinteger(L, 14); /* 3rd argument */
- lua_call(L, 3, 1); /* call 'f' with 3 arguments and 1 result */
- lua_setglobal(L, "a"); /* set global 'a' */
-</pre><p>
-Note that the code above is "balanced":
-at its end, the stack is back to its original configuration.
-This is considered good programming practice.

-
-
-<p>
-In order to communicate properly with Lua,
-a C function must use the following protocol,
-which defines the way parameters and results are passed:
-a C function receives its arguments from Lua in its stack
-in direct order (the first argument is pushed first).
-So, when the function starts,
-<code>lua_gettop(L)</code> returns the number of arguments received by the function.
-The first argument (if any) is at index 1
-and its last argument is at index <code>lua_gettop(L)</code>.
-To return values to Lua, a C function just pushes them onto the stack,
-in direct order (the first result is pushed first),
-and returns the number of results.
-Any other value in the stack below the results will be properly
-discarded by Lua.
-Like a Lua function, a C function called by Lua can also return
-many results.
-
-
-<p>
-As an example, the following function receives a variable number

-<pre>void lua_pushcclosure (lua_State *L, lua_CFunction fn, int n);</pre>
-
-<p>
-Pushes a new C closure onto the stack.
-
-
-<p>
-When a C function is created,
-it is possible to associate some values with it,
-thus creating a C closure (see <a href="#4.4">§4.4</a>);
-these values are then accessible to the function whenever it is called.
-To associate values with a C function,
-first these values should be pushed onto the stack
-(when there are multiple values, the first value is pushed first).
-Then <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>
-is called to create and push the C function onto the stack,
-with the argument <code>n</code> telling how many values should be
-associated with the function.
-<a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a> also pops these values from the stack.
-
-
-<p>
-The maximum value for <code>n</code> is 255.
-
-
-<p>
-When <code>n</code> is zero,
-this function creates a <em>light C function</em>,
-which is just a pointer to the C function.
-In that case, it never throws a memory error.

-
-<p>
-Pushes a C function onto the stack.
-This function receives a pointer to a C function
-and pushes onto the stack a Lua value of type <code>function</code> that,
-when called, invokes the corresponding C function.
-
-
-<p>
-Any function to be registered in Lua must
-follow the correct protocol to receive its parameters
-and return its results (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).

-<pre>const char *lua_pushfstring (lua_State *L, const char *fmt, ...);</pre>
-
-<p>
-Pushes onto the stack a formatted string
-and returns a pointer to this string.
-It is similar to the ISO C function <code>sprintf</code>,
-but has some important differences:
-
-<ul>
-
-<li>
-You do not have to allocate space for the result:
-the result is a Lua string and Lua takes care of memory allocation
-(and deallocation, through garbage collection).
-</li>
-
-<li>
-The conversion specifiers are quite restricted.
-There are no flags, widths, or precisions.
-The conversion specifiers can only be
-'<code>%%</code>' (inserts a '<code>%</code>' in the string),
-'<code>%s</code>' (inserts a zero-terminated string, with no size restrictions),
-'<code>%f</code>' (inserts a <a href="#lua_Number"><code>lua_Number</code></a>),
-'<code>%p</code>' (inserts a pointer as a hexadecimal numeral),
-'<code>%d</code>' (inserts an <code>int</code>), and

-Converts the Lua value at the given index to a C string.

-The Lua value must be a string or a number;
-otherwise, the function returns <code>NULL</code>.

-This string always has a zero ('<code>\0</code>')

-The fields of <a href="#lua_Debug"><code>lua_Debug</code></a> have the following meaning:
-
-<ul>
-
-<li><b><code>source</code>: </b>
-the source of the chunk that created the function.
-If <code>source</code> starts with a '<code>@</code>',
-it means that the function was defined in a file where
-the file name follows the '<code>@</code>'.
-If <code>source</code> starts with a '<code>=</code>',
-the remainder of its contents describe the source in a user-dependent manner.
-Otherwise,
-the function was defined in a string where

-<code>"C"</code> if it is a C function,
-<code>"main"</code> if it is the main part of a chunk.
-</li>
-
-<li><b><code>currentline</code>: </b>
-the current line where the given function is executing.
-When no line information is available,
-<code>currentline</code> is set to -1.
-</li>
-
-<li><b><code>name</code>: </b>
-a reasonable name for the given function.
-Because functions in Lua are first-class values,
-they do not have a fixed name:
-some functions can be the value of multiple global variables,
-while others can be stored only in a table field.
-The <code>lua_getinfo</code> function checks how the function was
-called to find a suitable name.
-If it cannot find a name,
-then <code>name</code> is set to <code>NULL</code>.
-</li>
-
-<li><b><code>namewhat</code>: </b>
-explains the <code>name</code> field.
-The value of <code>namewhat</code> can be
-<code>"global"</code>, <code>"local"</code>, <code>"method"</code>,
-<code>"field"</code>, <code>"upvalue"</code>, or <code>""</code> (the empty string),
-according to how the function was called.
-(Lua uses the empty string when no other option seems to apply.)
-</li>
-
-<li><b><code>istailcall</code>: </b>
-true if this function invocation was called by a tail call.
-In this case, the caller of this level is not in the stack.
-</li>
-
-<li><b><code>nups</code>: </b>
-the number of upvalues of the function.

-Gets information about a closure's upvalue.
-(For Lua functions,
-upvalues are the external local variables that the function uses,
-and that are consequently included in its closure.)
-<a href="#lua_getupvalue"><code>lua_getupvalue</code></a> gets the index <code>n</code> of an upvalue,
-pushes the upvalue's value onto the stack,

-<code>funcindex</code> points to the closure in the stack.
-(Upvalues have no particular order,
-as they are active through the whole function.
-So, they are numbered in an arbitrary order.)
-
-
-<p>
-Returns <code>NULL</code> (and pushes nothing)

-<pre>typedef void (*lua_Hook) (lua_State *L, lua_Debug *ar);</pre>
-
-<p>
-Type for debugging hook functions.
-
-
-<p>
-Whenever a hook is called, its <code>ar</code> argument has its field
-<code>event</code> set to the specific event that triggered the hook.
-Lua identifies these events with the following constants:
-<a name="pdf-LUA_HOOKCALL"><code>LUA_HOOKCALL</code></a>, <a name="pdf-LUA_HOOKRET"><code>LUA_HOOKRET</code></a>,
-<a name="pdf-LUA_HOOKTAILCALL"><code>LUA_HOOKTAILCALL</code></a>, <a name="pdf-LUA_HOOKLINE"><code>LUA_HOOKLINE</code></a>,
-and <a name="pdf-LUA_HOOKCOUNT"><code>LUA_HOOKCOUNT</code></a>.
-Moreover, for line events, the field <code>currentline</code> is also set.
-To get the value of any other field in <code>ar</code>,
-the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-
-
-<p>
-For call events, <code>event</code> can be <code>LUA_HOOKCALL</code>,
-the normal value, or <code>LUA_HOOKTAILCALL</code>, for a tail call;
-in this case, there will be no corresponding return event.
-
-
-<p>
-While Lua is running a hook, it disables other calls to hooks.
-Therefore, if a hook calls back Lua to execute a function or a chunk,
-this execution occurs without any calls to hooks.
-
-
-<p>
-Hook functions cannot have continuations,
-that is, they cannot call <a href="#lua_yieldk"><code>lua_yieldk</code></a>,
-<a href="#lua_pcallk"><code>lua_pcallk</code></a>, or <a href="#lua_callk"><code>lua_callk</code></a> with a non-null <code>k</code>.

-Argument <code>f</code> is the hook function.
-<code>mask</code> specifies on which events the hook will be called:

-The <code>count</code> argument is only meaningful when the mask
-includes <code>LUA_MASKCOUNT</code>.
-For each event, the hook is called as explained below:
-
-<ul>
-
-<li><b>The call hook: </b> is called when the interpreter calls a function.
-The hook is called just after Lua enters the new function,
-before the function gets its arguments.
-</li>
-
-<li><b>The return hook: </b> is called when the interpreter returns from a function.
-The hook is called just before Lua leaves the function.
-There is no standard way to access the values
-to be returned by the function.
-</li>
-
-<li><b>The line hook: </b> is called when the interpreter is about to
-start the execution of a new line of code,
-or when it jumps back in the code (even to the same line).
-(This event only happens while Lua is executing a Lua function.)

-<h1>5 – <a name="5">The Auxiliary Library</a></h1>
-
-<p>
-
-The <em>auxiliary library</em> provides several convenient functions
-to interface C with Lua.
-While the basic API provides the primitive functions for all
-interactions between C and Lua,
-the auxiliary library provides higher-level functions for some
-common tasks.
-
-
-<p>
-All functions and types from the auxiliary library
-are defined in header file <code>lauxlib.h</code> and
-have a prefix <code>luaL_</code>.
-
-
-<p>
-All functions in the auxiliary library are built on
-top of the basic API,
-and so they provide nothing that cannot be done with that API.
-Nevertheless, the use of the auxiliary library ensures
-more consistency to your code.
-
-
-<p>
-Several functions in the auxiliary library use internally some
-extra stack slots.
-When a function in the auxiliary library uses less than five slots,
-it does not check the stack size;
-it simply assumes that there are enough slots.
-
-
-<p>
-Several functions in the auxiliary library are used to
-check C function arguments.
-Because the error message is formatted for arguments
-(e.g., "<code>bad argument #1</code>"),
-you should not use these functions for other stack values.
-
-
-<p>
-Functions called <code>luaL_check*</code>
-always throw an error if the check is not satisfied.
-
-
-
-<h2>5.1 – <a name="5.1">Functions and Types</a></h2>

-<hr><h3><a name="luaL_Buffer"><code>luaL_Buffer</code></a></h3>
-<pre>typedef struct luaL_Buffer luaL_Buffer;</pre>
-
-<p>
-Type for a <em>string buffer</em>.
-
-
-<p>
-A string buffer allows C code to build Lua strings piecemeal.
-Its pattern of use is as follows:
-
-<ul>
-
-<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
-
-<li>Then initialize it with a call <code>luaL_buffinit(L, &b)</code>.</li>
-
-<li>
-Then add string pieces to the buffer calling any of
-the <code>luaL_add*</code> functions.
-</li>
-
-<li>
-Finish by calling <code>luaL_pushresult(&b)</code>.
-This call leaves the final string on the top of the stack.
-</li>
-
-</ul>
-
-<p>
-If you know beforehand the total size of the resulting string,
-you can use the buffer like this:
-
-<ul>
-
-<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
-
-<li>Then initialize it and preallocate a space of
-size <code>sz</code> with a call <code>luaL_buffinitsize(L, &b, sz)</code>.</li>
-
-<li>Then copy the string into that space.</li>
-
-<li>
-Finish by calling <code>luaL_pushresultsize(&b, sz)</code>,
-where <code>sz</code> is the total size of the resulting string
-copied into that space.
-</li>
-
-</ul>
-
-<p>
-During its normal operation,
-a string buffer uses a variable number of stack slots.
-So, while using a buffer, you cannot assume that you know where
-the top of the stack is.
-You can use the stack between successive calls to buffer operations
-as long as that use is balanced;
-that is,
-when you call a buffer operation,
-the stack is at the same level
-it was immediately after the previous buffer operation.
-(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
-After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a> the stack is back to its
-level when the buffer was initialized,
-plus the final string on its top.

-<p>
-Calls a metamethod.

-
-<p>
-If the object at index <code>obj</code> has a metatable and this
-metatable has a field <code>e</code>,
-this function calls this field passing the object as its only argument.

-<h1>6 – <a name="6">Standard Libraries</a></h1>
-
-<p>
-The standard Lua libraries provide useful functions
-that are implemented directly through the C API.
-Some of these functions provide essential services to the language
-(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
-others provide access to "outside" services (e.g., I/O);
-and others could be implemented in Lua itself,
-but are quite useful or have critical performance requirements that
-deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
-
-
-<p>
-All libraries are implemented through the official C API
-and are provided as separate C modules.
-Currently, Lua has the following standard libraries:
-
-<ul>
-
-<li>basic library (<a href="#6.1">§6.1</a>);</li>
-
-<li>coroutine library (<a href="#6.2">§6.2</a>);</li>
-
-<li>package library (<a href="#6.3">§6.3</a>);</li>
-
-<li>string manipulation (<a href="#6.4">§6.4</a>);</li>
-
-<li>table manipulation (<a href="#6.5">§6.5</a>);</li>
-
-<li>mathematical functions (<a href="#6.6">§6.6</a>) (sin, log, etc.);</li>
-
-<li>bitwise operations (<a href="#6.7">§6.7</a>);</li>
-
-<li>input and output (<a href="#6.8">§6.8</a>);</li>
-
-<li>operating system facilities (<a href="#6.9">§6.9</a>);</li>
-
-<li>debug facilities (<a href="#6.10">§6.10</a>).</li>
-
-</ul><p>
-Except for the basic and the package libraries,
-each library provides all its functions as fields of a global table
-or as methods of its objects.
-
-
-<p>
-To have access to these libraries,
-the C host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
-which opens all standard libraries.
-Alternatively,
-the host program can open them individually by using
-<a href="#luaL_requiref"><code>luaL_requiref</code></a> to call
-<a name="pdf-luaopen_base"><code>luaopen_base</code></a> (for the basic library),
-<a name="pdf-luaopen_package"><code>luaopen_package</code></a> (for the package library),
-<a name="pdf-luaopen_coroutine"><code>luaopen_coroutine</code></a> (for the coroutine library),
-<a name="pdf-luaopen_string"><code>luaopen_string</code></a> (for the string library),

-<h2>6.1 – <a name="6.1">Basic Functions</a></h2>
-
-<p>
-The basic library provides core functions to Lua.
-If you do not include this library in your application,
-you should check carefully whether you need to provide
-implementations for some of its facilities.
-
-
-<p>
-<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
-Issues an error when
-the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
-otherwise, returns all its arguments.
-<code>message</code> is an error message;
-when absent, it defaults to "assertion failed!"
-
-
-
-
-<p>
-<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage ([opt [, arg]])</code></a></h3>
-
-
-<p>
-This function is a generic interface to the garbage collector.
-It performs different functions according to its first argument, <code>opt</code>:
-
-<ul>
-
-<li><b>"<code>collect</code>": </b>
-performs a full garbage-collection cycle.
-This is the default option.
-</li>
-
-<li><b>"<code>stop</code>": </b>
-stops automatic execution of the garbage collector.
-The collector will run only when explicitly invoked,
-until a call to restart it.
-</li>
-
-<li><b>"<code>restart</code>": </b>
-restarts automatic execution of the garbage collector.
-</li>
-
-<li><b>"<code>count</code>": </b>
-returns the total memory in use by Lua (in Kbytes) and
-a second value with the total memory in bytes modulo 1024.
-The first value has a fractional part,
-so the following equality is always true:
-
-<pre>
- k, b = collectgarbage("count")
- assert(k*1024 == math.floor(k)*1024 + b)
-</pre><p>
-(The second result is useful when Lua is compiled
-with a non floating-point type for numbers.)
-</li>
-
-<li><b>"<code>step</code>": </b>
-performs a garbage-collection step.
-The step "size" is controlled by <code>arg</code>
-(larger values mean more steps) in a non-specified way.
-If you want to control the step size
-you must experimentally tune the value of <code>arg</code>.
-Returns <b>true</b> if the step finished a collection cycle.
-</li>
-
-<li><b>"<code>setpause</code>": </b>
-sets <code>arg</code> as the new value for the <em>pause</em> of
-the collector (see <a href="#2.5">§2.5</a>).
-Returns the previous value for <em>pause</em>.
-</li>
-
-<li><b>"<code>setstepmul</code>": </b>
-sets <code>arg</code> as the new value for the <em>step multiplier</em> of
-the collector (see <a href="#2.5">§2.5</a>).
-Returns the previous value for <em>step</em>.
-</li>
-
-<li><b>"<code>isrunning</code>": </b>
-returns a boolean that tells whether the collector is running
-(i.e., not stopped).
-</li>
-
-<li><b>"<code>generational</code>": </b>
-changes the collector to generational mode.
-This is an experimental feature (see <a href="#2.5">§2.5</a>).
-</li>
-
-<li><b>"<code>incremental</code>": </b>
-changes the collector to incremental mode.
-This is the default mode.
-</li>
-
-</ul>

-<hr><h3><a name="pdf-dofile"><code>dofile ([filename])</code></a></h3>
-Opens the named file and executes its contents as a Lua chunk.
-When called without arguments,
-<code>dofile</code> executes the contents of the standard input (<code>stdin</code>).
-Returns all values returned by the chunk.
-In case of errors, <code>dofile</code> propagates the error
-to its caller (that is, <code>dofile</code> does not run in protected mode).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
-Terminates the last protected function called
-and returns <code>message</code> as the error message.
-Function <code>error</code> never returns.
-
-
-<p>
-Usually, <code>error</code> adds some information about the error position
-at the beginning of the message, if the message is a string.
-The <code>level</code> argument specifies how to get the error position.
-With level 1 (the default), the error position is where the
-<code>error</code> function was called.
-Level 2 points the error to where the function
-that called <code>error</code> was called; and so on.
-Passing a level 0 avoids the addition of error position information
-to the message.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
-A global variable (not a function) that
-holds the global environment (see <a href="#2.2">§2.2</a>).
-Lua itself does not use this variable;
-changing its value does not affect any environment,
-nor vice-versa.

-<hr><h3><a name="pdf-getmetatable"><code>getmetatable (object)</code></a></h3>
-
-
-<p>
-If <code>object</code> does not have a metatable, returns <b>nil</b>.
-Otherwise,
-if the object's metatable has a <code>"__metatable"</code> field,
-returns the associated value.
-Otherwise, returns the metatable of the given object.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
-
-
-<p>
-If <code>t</code> has a metamethod <code>__ipairs</code>,
-calls it with <code>t</code> as argument and returns the first three
-results from the call.
-
-
-<p>
-Otherwise,
-returns three values: an iterator function, the table <code>t</code>, and 0,
-so that the construction
-
-<pre>
- for i,v in ipairs(t) do <em>body</em> end
-</pre><p>
-will iterate over the pairs (<code>1,t[1]</code>), (<code>2,t[2]</code>), ...,
-up to the first integer key absent from the table.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-load"><code>load (ld [, source [, mode [, env]]])</code></a></h3>
-
-
-<p>
-Loads a chunk.
-
-
-<p>
-If <code>ld</code> is a string, the chunk is this string.
-If <code>ld</code> is a function,
-<code>load</code> calls it repeatedly to get the chunk pieces.
-Each call to <code>ld</code> must return a string that concatenates
-with previous results.
-A return of an empty string, <b>nil</b>, or no value signals the end of the chunk.
-
-
-<p>
-If there are no syntactic errors,
-returns the compiled chunk as a function;
-otherwise, returns <b>nil</b> plus the error message.
-
-
-<p>
-If the resulting function has upvalues,
-the first upvalue is set to the value of <code>env</code>,
-if that parameter is given,
-or to the value of the global environment.
-(When you load a main chunk,
-the resulting function will always have exactly one upvalue,
-the <code>_ENV</code> variable (see <a href="#2.2">§2.2</a>).
-When you load a binary chunk created from a function (see <a href="#pdf-string.dump"><code>string.dump</code></a>),
-the resulting function can have arbitrary upvalues.)
-
-
-<p>
-<code>source</code> is used as the source of the chunk for error messages
-and debug information (see <a href="#4.9">§4.9</a>).
-When absent,
-it defaults to <code>ld</code>, if <code>ld</code> is a string,
-or to "<code>=(load)</code>" otherwise.
-
-
-<p>
-The string <code>mode</code> controls whether the chunk can be text or binary
-(that is, a precompiled chunk).
-It may be the string "<code>b</code>" (only binary chunks),
-"<code>t</code>" (only text chunks),
-or "<code>bt</code>" (both binary and text).
-The default is "<code>bt</code>".

-<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
-
-
-<p>
-Allows a program to traverse all fields of a table.
-Its first argument is a table and its second argument
-is an index in this table.
-<code>next</code> returns the next index of the table
-and its associated value.
-When called with <b>nil</b> as its second argument,
-<code>next</code> returns an initial index
-and its associated value.
-When called with the last index,
-or with <b>nil</b> in an empty table,
-<code>next</code> returns <b>nil</b>.
-If the second argument is absent, then it is interpreted as <b>nil</b>.
-In particular,
-you can use <code>next(t)</code> to check whether a table is empty.
-
-
-<p>
-The order in which the indices are enumerated is not specified,
-<em>even for numeric indices</em>.
-(To traverse a table in numeric order,
-use a numerical <b>for</b>.)
-
-
-<p>
-The behavior of <code>next</code> is undefined if,
-during the traversal,
-you assign any value to a non-existent field in the table.
-You may however modify existing fields.
-In particular, you may clear existing fields.

-<hr><h3><a name="pdf-pcall"><code>pcall (f [, arg1, ···])</code></a></h3>
-
-
-<p>
-Calls function <code>f</code> with
-the given arguments in <em>protected mode</em>.
-This means that any error inside <code>f</code> is not propagated;
-instead, <code>pcall</code> catches the error
-and returns a status code.
-Its first result is the status code (a boolean),
-which is true if the call succeeds without errors.
-In such case, <code>pcall</code> also returns all results from the call,
-after this first result.
-In case of any error, <code>pcall</code> returns <b>false</b> plus the error message.

-
-<h2>6.3 – <a name="6.3">Modules</a></h2>
-
-<p>
-The package library provides basic
-facilities for loading modules in Lua.
-It exports one function directly in the global environment:
-<a href="#pdf-require"><code>require</code></a>.
-Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
-
-
-<p>
-<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
-
-
-<p>
-Loads the given module.
-The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
-to determine whether <code>modname</code> is already loaded.
-If it is, then <code>require</code> returns the value stored
-at <code>package.loaded[modname]</code>.
-Otherwise, it tries to find a <em>loader</em> for the module.
-
-
-<p>
-To find a loader,
-<code>require</code> is guided by the <a href="#pdf-package.searchers"><code>package.searchers</code></a> sequence.
-By changing this sequence,
-we can change how <code>require</code> looks for a module.
-The following explanation is based on the default configuration
-for <a href="#pdf-package.searchers"><code>package.searchers</code></a>.
-
-
-<p>
-First <code>require</code> queries <code>package.preload[modname]</code>.
-If it has a value,
-this value (which should be a function) is the loader.
-Otherwise <code>require</code> searches for a Lua loader using the
-path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
-If that also fails, it searches for a C loader using the
-path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-If that also fails,
-it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.searchers"><code>package.searchers</code></a>).
-
-
-<p>
-Once a loader is found,
-<code>require</code> calls the loader with two arguments:
-<code>modname</code> and an extra value dependent on how it got the loader.
-(If the loader came from a file,
-this extra value is the file name.)
-If the loader returns any non-nil value,
-<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
-If the loader does not return a non-nil value and
-has not assigned any value to <code>package.loaded[modname]</code>,
-then <code>require</code> assigns <b>true</b> to this entry.
-In any case, <code>require</code> returns the
-final value of <code>package.loaded[modname]</code>.
-
-
-<p>
-If there is any error loading or running the module,
-or if it cannot find any loader for the module,
-then <code>require</code> raises an error.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.config"><code>package.config</code></a></h3>
-
-
-<p>
-A string describing some compile-time configurations for packages.
-This string is a sequence of lines:
-
-<ul>
-
-<li>The first line is the directory separator string.
-Default is '<code>\</code>' for Windows and '<code>/</code>' for all other systems.</li>
-
-<li>The second line is the character that separates templates in a path.
-Default is '<code>;</code>'.</li>
-
-<li>The third line is the string that marks the
-substitution points in a template.
-Default is '<code>?</code>'.</li>
-
-<li>The fourth line is a string that, in a path in Windows,
-is replaced by the executable's directory.
-Default is '<code>!</code>'.</li>
-
-<li>The fifth line is a mark to ignore all text before it
-when building the <code>luaopen_</code> function name.
-Default is '<code>-</code>'.</li>
-
-</ul>
-
-
-
-<p>
-<hr><h3><a name="pdf-package.cpath"><code>package.cpath</code></a></h3>
-
-
-<p>
-The path used by <a href="#pdf-require"><code>require</code></a> to search for a C loader.
-
-
-<p>
-Lua initializes the C path <a href="#pdf-package.cpath"><code>package.cpath</code></a> in the same way
-it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,
-using the environment variable <a name="pdf-LUA_CPATH_5_2"><code>LUA_CPATH_5_2</code></a>
-or the environment variable <a name="pdf-LUA_CPATH"><code>LUA_CPATH</code></a>
-or a default path defined in <code>luaconf.h</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loaded"><code>package.loaded</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control which
-modules are already loaded.
-When you require a module <code>modname</code> and
-<code>package.loaded[modname]</code> is not false,
-<a href="#pdf-require"><code>require</code></a> simply returns the value stored there.
-
-
-<p>
-This variable is only a reference to the real table;
-assignments to this variable do not change the
-table used by <a href="#pdf-require"><code>require</code></a>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>
-
-
-<p>
-Dynamically links the host program with the C library <code>libname</code>.
-
-
-<p>
-If <code>funcname</code> is "<code>*</code>",
-then it only links with the library,
-making the symbols exported by the library
-available to other dynamically linked libraries.
-Otherwise,
-it looks for a function <code>funcname</code> inside the library
-and returns this function as a C function.
-So, <code>funcname</code> must follow the <a href="#lua_CFunction"><code>lua_CFunction</code></a> prototype
-(see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
-
-
-<p>
-This is a low-level function.
-It completely bypasses the package and module system.
-Unlike <a href="#pdf-require"><code>require</code></a>,
-it does not perform any path searching and
-does not automatically adds extensions.
-<code>libname</code> must be the complete file name of the C library,
-including if necessary a path and an extension.
-<code>funcname</code> must be the exact name exported by the C library
-(which may depend on the C compiler and linker used).
-
-
-<p>
-This function is not supported by Standard C.
-As such, it is only available on some platforms
-(Windows, Linux, Mac OS X, Solaris, BSD,
-plus other Unix systems that support the <code>dlfcn</code> standard).

-<p>
-<hr><h3><a name="pdf-package.path"><code>package.path</code></a></h3>
-
-
-<p>
-The path used by <a href="#pdf-require"><code>require</code></a> to search for a Lua loader.
-
-
-<p>
-At start-up, Lua initializes this variable with
-the value of the environment variable <a name="pdf-LUA_PATH_5_2"><code>LUA_PATH_5_2</code></a> or
-the environment variable <a name="pdf-LUA_PATH"><code>LUA_PATH</code></a> or
-with a default path defined in <code>luaconf.h</code>,
-if those environment variables are not defined.
-Any "<code>;;</code>" in the value of the environment variable
-is replaced by the default path.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.preload"><code>package.preload</code></a></h3>
-
-
-<p>
-A table to store loaders for specific modules
-(see <a href="#pdf-require"><code>require</code></a>).
-
-
-<p>
-This variable is only a reference to the real table;
-assignments to this variable do not change the
-table used by <a href="#pdf-require"><code>require</code></a>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.searchers"><code>package.searchers</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
-
-
-<p>
-Each entry in this table is a <em>searcher function</em>.
-When looking for a module,
-<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
-with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
-sole parameter.
-The function can return another function (the module <em>loader</em>)
-plus an extra value that will be passed to that loader,
-or a string explaining why it did not find that module
-(or <b>nil</b> if it has nothing to say).
-
-
-<p>
-Lua initializes this table with four searcher functions.
-
-
-<p>
-The first searcher simply looks for a loader in the
-<a href="#pdf-package.preload"><code>package.preload</code></a> table.
-
-
-<p>
-The second searcher looks for a loader as a Lua library,
-using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
-The search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-
-
-<p>
-The third searcher looks for a loader as a C library,
-using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-Again,
-the search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-For instance,
-if the C path is the string
-
-<pre>
- "./?.so;./?.dll;/usr/local/?/init.so"
-</pre><p>
-the searcher for module <code>foo</code>
-will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
-and <code>/usr/local/foo/init.so</code>, in that order.
-Once it finds a C library,
-this searcher first uses a dynamic link facility to link the
-application with the library.
-Then it tries to find a C function inside the library to
-be used as the loader.
-The name of this C function is the string "<code>luaopen_</code>"
-concatenated with a copy of the module name where each dot
-is replaced by an underscore.
-Moreover, if the module name has a hyphen,
-its prefix up to (and including) the first hyphen is removed.
-For instance, if the module name is <code>a.v1-b.c</code>,
-the function name will be <code>luaopen_b_c</code>.
-
-
-<p>
-The fourth searcher tries an <em>all-in-one loader</em>.
-It searches the C path for a library for
-the root name of the given module.
-For instance, when requiring <code>a.b.c</code>,
-it will search for a C library for <code>a</code>.
-If found, it looks into it for an open function for
-the submodule;
-in our example, that would be <code>luaopen_a_b_c</code>.
-With this facility, a package can pack several C submodules
-into one single library,
-with each submodule keeping its original open function.
-
-
-<p>
-All searchers except the first one (preload) return as the extra value
-the file name where the module was found,
-as returned by <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
-The first searcher returns no extra value.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.searchpath"><code>package.searchpath (name, path [, sep [, rep]])</code></a></h3>
-
-
-<p>
-Searches for the given <code>name</code> in the given <code>path</code>.
-
-
-<p>
-A path is a string containing a sequence of
-<em>templates</em> separated by semicolons.
-For each template,
-the function replaces each interrogation mark (if any)
-in the template with a copy of <code>name</code>
-wherein all occurrences of <code>sep</code>
-(a dot, by default)
-were replaced by <code>rep</code>
-(the system's directory separator, by default),
-and then tries to open the resulting file name.
-
-
-<p>
-For instance, if the path is the string
-
-<pre>
- "./?.lua;./?.lc;/usr/local/?/init.lua"
-</pre><p>
-the search for the name <code>foo.a</code>
-will try to open the files
-<code>./foo/a.lua</code>, <code>./foo/a.lc</code>, and
-<code>/usr/local/foo/a/init.lua</code>, in that order.
-
-
-<p>
-Returns the resulting name of the first file that it can
-open in read mode (after closing the file),
-or <b>nil</b> plus an error message if none succeeds.
-(This error message lists all file names it tried to open.)
-
-
-
-
-
-
-
-<h2>6.4 – <a name="6.4">String Manipulation</a></h2>
-
-<p>
-This library provides generic functions for string manipulation,
-such as finding and extracting substrings, and pattern matching.
-When indexing a string in Lua, the first character is at position 1
-(not at 0, as in C).
-Indices are allowed to be negative and are interpreted as indexing backwards,
-from the end of the string.
-Thus, the last character is at position -1, and so on.
-
-
-<p>
-The string library provides all its functions inside the table
-<a name="pdf-string"><code>string</code></a>.
-It also sets a metatable for strings
-where the <code>__index</code> field points to the <code>string</code> table.
-Therefore, you can use the string functions in object-oriented style.
-For instance, <code>string.byte(s,i)</code>
-can be written as <code>s:byte(i)</code>.
-
-
-<p>
-The string library assumes one-byte character encodings.
-
-
-<p>
-<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
-Returns the internal numerical codes of the characters <code>s[i]</code>,
-<code>s[i+1]</code>, ..., <code>s[j]</code>.
-The default value for <code>i</code> is 1;
-the default value for <code>j</code> is <code>i</code>.
-These indices are corrected
-following the same rules of function <a href="#pdf-string.sub"><code>string.sub</code></a>.
-
-
-<p>
-Numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.char"><code>string.char (···)</code></a></h3>
-Receives zero or more integers.
-Returns a string with length equal to the number of arguments,
-in which each character has the internal numerical code equal
-to its corresponding argument.
-
-
-<p>
-Numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.dump"><code>string.dump (function)</code></a></h3>
-
-
-<p>
-Returns a string containing a binary representation of the given function,
-so that a later <a href="#pdf-load"><code>load</code></a> on this string returns
-a copy of the function (but with new upvalues).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
-
-
-<p>
-Looks for the first match of
-<code>pattern</code> in the string <code>s</code>.
-If it finds a match, then <code>find</code> returns the indices of <code>s</code>
-where this occurrence starts and ends;
-otherwise, it returns <b>nil</b>.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is 1 and can be negative.
-A value of <b>true</b> as a fourth, optional argument <code>plain</code>
-turns off the pattern matching facilities,
-so the function does a plain "find substring" operation,
-with no characters in <code>pattern</code> being considered magic.
-Note that if <code>plain</code> is given, then <code>init</code> must be given as well.
-
-
-<p>
-If the pattern has captures,
-then in a successful match
-the captured values are also returned,
-after the two indices.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, ···)</code></a></h3>
-
-
-<p>
-Returns a formatted version of its variable number of arguments
-following the description given in its first argument (which must be a string).
-The format string follows the same rules as the ISO C function <code>sprintf</code>.
-The only differences are that the options/modifiers
-<code>*</code>, <code>h</code>, <code>L</code>, <code>l</code>, <code>n</code>,
-and <code>p</code> are not supported
-and that there is an extra option, <code>q</code>.
-The <code>q</code> option formats a string between double quotes,
-using escape sequences when necessary to ensure that
-it can safely be read back by the Lua interpreter.
-For instance, the call
-
-<pre>
- string.format('%q', 'a string with "quotes" and \n new line')
-</pre><p>
-may produce the string:
-
-<pre>
- "a string with \"quotes\" and \
- new line"
-</pre>
-
-<p>
-Options
-<code>A</code> and <code>a</code> (when available),
-<code>E</code>, <code>e</code>, <code>f</code>,
-<code>G</code>, and <code>g</code> all expect a number as argument.
-Options <code>c</code>, <code>d</code>,
-<code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code>
-also expect a number,
-but the range of that number may be limited by
-the underlying C implementation.
-For options <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code>,
-the number cannot be negative.
-Option <code>q</code> expects a string;
-option <code>s</code> expects a string without embedded zeros.
-If the argument to option <code>s</code> is not a string,
-it is converted to one following the same rules of <a href="#pdf-tostring"><code>tostring</code></a>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern)</code></a></h3>
-Returns an iterator function that,
-each time it is called,
-returns the next captures from <code>pattern</code> over the string <code>s</code>.
-If <code>pattern</code> specifies no captures,
-then the whole match is produced in each call.
-
-
-<p>
-As an example, the following loop
-will iterate over all the words from string <code>s</code>,
-printing one per line:
-
-<pre>
- s = "hello world from Lua"
- for w in string.gmatch(s, "%a+") do
- print(w)
- end
-</pre><p>
-The next example collects all pairs <code>key=value</code> from the
-given string into a table:
-
-<pre>
- t = {}
- s = "from=world, to=Lua"
- for k, v in string.gmatch(s, "(%w+)=(%w+)") do
- t[k] = v
- end
-</pre>
-
-<p>
-For this function, a caret '<code>^</code>' at the start of a pattern does not
-work as an anchor, as this would prevent the iteration.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
-Returns a copy of <code>s</code>
-in which all (or the first <code>n</code>, if given)
-occurrences of the <code>pattern</code> have been
-replaced by a replacement string specified by <code>repl</code>,
-which can be a string, a table, or a function.
-<code>gsub</code> also returns, as its second value,
-the total number of matches that occurred.
-The name <code>gsub</code> comes from <em>Global SUBstitution</em>.
-
-
-<p>
-If <code>repl</code> is a string, then its value is used for replacement.
-The character <code>%</code> works as an escape character:
-any sequence in <code>repl</code> of the form <code>%<em>d</em></code>,
-with <em>d</em> between 1 and 9,
-stands for the value of the <em>d</em>-th captured substring.
-The sequence <code>%0</code> stands for the whole match.
-The sequence <code>%%</code> stands for a single <code>%</code>.
-
-
-<p>
-If <code>repl</code> is a table, then the table is queried for every match,
-using the first capture as the key.
-
-
-<p>
-If <code>repl</code> is a function, then this function is called every time a
-match occurs, with all captured substrings passed as arguments,
-in order.
-
-
-<p>
-In any case,
-if the pattern specifies no captures,
-then it behaves as if the whole pattern was inside a capture.
-
-
-<p>
-If the value returned by the table query or by the function call
-is a string or a number,
-then it is used as the replacement string;
-otherwise, if it is <b>false</b> or <b>nil</b>,
-then there is no replacement
-(that is, the original match is kept in the string).
-
-
-<p>
-Here are some examples:
-
-<pre>
- x = string.gsub("hello world", "(%w+)", "%1 %1")
- --> x="hello hello world world"
-
- x = string.gsub("hello world", "%w+", "%0 %0", 1)
- --> x="hello hello world"
-
- x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
- --> x="world hello Lua from"
-
- x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
- --> x="home = /home/roberto, user = roberto"
-
- x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
- return load(s)()
- end)
- --> x="4+5 = 9"
-
- local t = {name="lua", version="5.2"}
- x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
- --> x="lua-5.2.tar.gz"
-</pre>
-
-
-
-<p>
-<hr><h3><a name="pdf-string.len"><code>string.len (s)</code></a></h3>
-Receives a string and returns its length.
-The empty string <code>""</code> has length 0.
-Embedded zeros are counted,
-so <code>"a\000bc\000"</code> has length 5.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.lower"><code>string.lower (s)</code></a></h3>
-Receives a string and returns a copy of this string with all
-uppercase letters changed to lowercase.
-All other characters are left unchanged.
-The definition of what an uppercase letter is depends on the current locale.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.match"><code>string.match (s, pattern [, init])</code></a></h3>
-Looks for the first <em>match</em> of
-<code>pattern</code> in the string <code>s</code>.
-If it finds one, then <code>match</code> returns
-the captures from the pattern;
-otherwise it returns <b>nil</b>.
-If <code>pattern</code> specifies no captures,
-then the whole match is returned.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is 1 and can be negative.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.rep"><code>string.rep (s, n [, sep])</code></a></h3>
-Returns a string that is the concatenation of <code>n</code> copies of
-the string <code>s</code> separated by the string <code>sep</code>.
-The default value for <code>sep</code> is the empty string
-(that is, no separator).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.reverse"><code>string.reverse (s)</code></a></h3>
-Returns a string that is the string <code>s</code> reversed.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.sub"><code>string.sub (s, i [, j])</code></a></h3>
-Returns the substring of <code>s</code> that
-starts at <code>i</code> and continues until <code>j</code>;
-<code>i</code> and <code>j</code> can be negative.
-If <code>j</code> is absent, then it is assumed to be equal to -1
-(which is the same as the string length).
-In particular,
-the call <code>string.sub(s,1,j)</code> returns a prefix of <code>s</code>
-with length <code>j</code>,
-and <code>string.sub(s, -i)</code> returns a suffix of <code>s</code>
-with length <code>i</code>.
-
-
-<p>
-If, after the translation of negative indices,
-<code>i</code> is less than 1,
-it is corrected to 1.
-If <code>j</code> is greater than the string length,
-it is corrected to that length.
-If, after these corrections,
-<code>i</code> is greater than <code>j</code>,
-the function returns the empty string.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.upper"><code>string.upper (s)</code></a></h3>
-Receives a string and returns a copy of this string with all
-lowercase letters changed to uppercase.
-All other characters are left unchanged.
-The definition of what a lowercase letter is depends on the current locale.
-
-
-
-<h3>6.4.1 – <a name="6.4.1">Patterns</a></h3>
-
-
-<h4>Character Class:</h4><p>
-A <em>character class</em> is used to represent a set of characters.
-The following combinations are allowed in describing a character class:
-
-<ul>
-
-<li><b><em>x</em>: </b>
-(where <em>x</em> is not one of the <em>magic characters</em>
-<code>^$()%.[]*+-?</code>)
-represents the character <em>x</em> itself.
-</li>
-
-<li><b><code>.</code>: </b> (a dot) represents all characters.</li>
-
-<li><b><code>%a</code>: </b> represents all letters.</li>
-
-<li><b><code>%c</code>: </b> represents all control characters.</li>
-
-<li><b><code>%d</code>: </b> represents all digits.</li>
-
-<li><b><code>%g</code>: </b> represents all printable characters except space.</li>
-
-<li><b><code>%l</code>: </b> represents all lowercase letters.</li>
-
-<li><b><code>%p</code>: </b> represents all punctuation characters.</li>
-
-<li><b><code>%s</code>: </b> represents all space characters.</li>
-
-<li><b><code>%u</code>: </b> represents all uppercase letters.</li>
-
-<li><b><code>%w</code>: </b> represents all alphanumeric characters.</li>
-
-<li><b><code>%x</code>: </b> represents all hexadecimal digits.</li>
-
-<li><b><code>%<em>x</em></code>: </b> (where <em>x</em> is any non-alphanumeric character)
-represents the character <em>x</em>.
-This is the standard way to escape the magic characters.
-Any punctuation character (even the non magic)
-can be preceded by a '<code>%</code>'
-when used to represent itself in a pattern.
-</li>
-
-<li><b><code>[<em>set</em>]</code>: </b>
-represents the class which is the union of all
-characters in <em>set</em>.
-A range of characters can be specified by
-separating the end characters of the range,
-in ascending order, with a '<code>-</code>',
-All classes <code>%</code><em>x</em> described above can also be used as
-components in <em>set</em>.
-All other characters in <em>set</em> represent themselves.
-For example, <code>[%w_]</code> (or <code>[_%w]</code>)
-represents all alphanumeric characters plus the underscore,
-<code>[0-7]</code> represents the octal digits,
-and <code>[0-7%l%-]</code> represents the octal digits plus
-the lowercase letters plus the '<code>-</code>' character.
-
-
-<p>
-The interaction between ranges and classes is not defined.
-Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
-have no meaning.
-</li>
-
-<li><b><code>[^<em>set</em>]</code>: </b>
-represents the complement of <em>set</em>,
-where <em>set</em> is interpreted as above.
-</li>
-
-</ul><p>
-For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
-the corresponding uppercase letter represents the complement of the class.
-For instance, <code>%S</code> represents all non-space characters.
-
-
-<p>
-The definitions of letter, space, and other character groups
-depend on the current locale.
-In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
-
-
-
-
-
-<h4>Pattern Item:</h4><p>
-A <em>pattern item</em> can be
-
-<ul>
-
-<li>
-a single character class,
-which matches any single character in the class;
-</li>
-
-<li>
-a single character class followed by '<code>*</code>',
-which matches 0 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>+</code>',
-which matches 1 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>-</code>',
-which also matches 0 or more repetitions of characters in the class.
-Unlike '<code>*</code>',
-these repetition items will always match the shortest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>?</code>',
-which matches 0 or 1 occurrence of a character in the class;
-</li>
-
-<li>
-<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
-such item matches a substring equal to the <em>n</em>-th captured string
-(see below);
-</li>
-
-<li>
-<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
-such item matches strings that start with <em>x</em>, end with <em>y</em>,
-and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
-This means that, if one reads the string from left to right,
-counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
-the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
-For instance, the item <code>%b()</code> matches expressions with
-balanced parentheses.
-</li>
-
-<li>
-<code>%f[<em>set</em>]</code>, a <em>frontier pattern</em>;
-such item matches an empty string at any position such that
-the next character belongs to <em>set</em>
-and the previous character does not belong to <em>set</em>.
-The set <em>set</em> is interpreted as previously described.
-The beginning and the end of the subject are handled as if
-they were the character '<code>\0</code>'.
-</li>
-
-</ul>
-
-
-
-
-<h4>Pattern:</h4><p>
-A <em>pattern</em> is a sequence of pattern items.
-A caret '<code>^</code>' at the beginning of a pattern anchors the match at the
-beginning of the subject string.
-A '<code>$</code>' at the end of a pattern anchors the match at the
-end of the subject string.
-At other positions,
-'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
-
-
-
-
-
-<h4>Captures:</h4><p>
-A pattern can contain sub-patterns enclosed in parentheses;
-they describe <em>captures</em>.
-When a match succeeds, the substrings of the subject string
-that match captures are stored (<em>captured</em>) for future use.
-Captures are numbered according to their left parentheses.
-For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
-the part of the string matching <code>"a*(.)%w(%s*)"</code> is
-stored as the first capture (and therefore has number 1);
-the character matching "<code>.</code>" is captured with number 2,
-and the part matching "<code>%s*</code>" has number 3.
-
-
-<p>
-As a special case, the empty capture <code>()</code> captures
-the current string position (a number).
-For instance, if we apply the pattern <code>"()aa()"</code> on the
-string <code>"flaaap"</code>, there will be two captures: 3 and 5.

-<h2>6.5 – <a name="6.5">Table Manipulation</a></h2>
-
-<p>
-This library provides generic functions for table manipulation.
-It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
-
-
-<p>
-Remember that, whenever an operation needs the length of a table,
-the table should be a proper sequence
-or have a <code>__len</code> metamethod (see <a href="#3.4.6">§3.4.6</a>).
-All functions ignore non-numeric keys
-in tables given as arguments.
-
-
-<p>
-For performance reasons,
-all table accesses (get/set) performed by these functions are raw.
-
-
-<p>
-<hr><h3><a name="pdf-table.concat"><code>table.concat (list [, sep [, i [, j]]])</code></a></h3>
-
-
-<p>
-Given a list where all elements are strings or numbers,
-returns the string <code>list[i]..sep..list[i+1] ··· sep..list[j]</code>.
-The default value for <code>sep</code> is the empty string,
-the default for <code>i</code> is 1,
-and the default for <code>j</code> is <code>#list</code>.
-If <code>i</code> is greater than <code>j</code>, returns the empty string.

-<h2>6.8 – <a name="6.8">Input and Output Facilities</a></h2>
-
-<p>
-The I/O library provides two different styles for file manipulation.
-The first one uses implicit file descriptors;
-that is, there are operations to set a default input file and a
-default output file,
-and all input/output operations are over these default files.
-The second style uses explicit file descriptors.
-
-
-<p>
-When using implicit file descriptors,
-all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
-When using explicit file descriptors,
-the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file descriptor
-and then all operations are supplied as methods of the file descriptor.
-
-
-<p>
-The table <code>io</code> also provides
-three predefined file descriptors with their usual meanings from C:
-<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
-The I/O library never closes these files.
-
-
-<p>
-Unless otherwise stated,
-all I/O functions return <b>nil</b> on failure
-(plus an error message as a second result and
-a system-dependent error code as a third result)
-and some value different from <b>nil</b> on success.
-On non-Posix systems,
-the computation of the error message and error code
-in case of errors
-may be not thread safe,
-because they rely on the global C variable <code>errno</code>.
-
-
-<p>
-<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
-
-
-<p>
-Equivalent to <code>file:close()</code>.

-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
-
-

-Equivalent to <code>io.output():flush()</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
-
-
-<p>
-When called with a file name, it opens the named file (in text mode),
-and sets its handle as the default input file.
-When called with a file handle,
-it simply sets this file handle as the default input file.
-When called without parameters,
-it returns the current default input file.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename ···])</code></a></h3>
-
-
-<p>
-Opens the given file name in read mode
-and returns an iterator function that
-works like <code>file:lines(···)</code> over the opened file.
-When the iterator function detects the end of file,
-it returns <b>nil</b> (to finish the loop) and automatically closes the file.
-
-
-<p>
-The call <code>io.lines()</code> (with no file name) is equivalent
-to <code>io.input():lines()</code>;
-that is, it iterates over the lines of the default input file.
-In this case it does not close the file when the loop ends.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.open"><code>io.open (filename [, mode])</code></a></h3>
-
-
-<p>
-This function opens a file,
-in the mode specified in the string <code>mode</code>.
-It returns a new file handle,
-or, in case of errors, <b>nil</b> plus an error message.
-
-
-<p>
-The <code>mode</code> string can be any of the following:
-
-<ul>
-<li><b>"<code>r</code>": </b> read mode (the default);</li>
-<li><b>"<code>w</code>": </b> write mode;</li>
-<li><b>"<code>a</code>": </b> append mode;</li>
-<li><b>"<code>r+</code>": </b> update mode, all previous data is preserved;</li>
-<li><b>"<code>w+</code>": </b> update mode, all previous data is erased;</li>
-<li><b>"<code>a+</code>": </b> append update mode, previous data is preserved,
- writing is only allowed at the end of file.</li>
-</ul><p>
-The <code>mode</code> string can also have a '<code>b</code>' at the end,
-which is needed in some systems to open the file in binary mode.

-<p>
-Closes <code>file</code>.
-Note that files are automatically closed when

-
-
-<p>
-When closing a file handle created with <a href="#pdf-io.popen"><code>io.popen</code></a>,
-<a href="#pdf-file:close"><code>file:close</code></a> returns the same values

-<hr><h3><a name="pdf-file:read"><code>file:read (···)</code></a></h3>
-
-
-<p>
-Reads the file <code>file</code>,
-according to the given formats, which specify what to read.
-For each format,
-the function returns a string (or a number) with the characters read,
-or <b>nil</b> if it cannot read data with the specified format.
-When called without formats,
-it uses a default format that reads the next line
-(see below).
-
-
-<p>
-The available formats are
-
-<ul>
-
-<li><b>"<code>*n</code>": </b>
-reads a number;
-this is the only format that returns a number instead of a string.
-</li>
-
-<li><b>"<code>*a</code>": </b>
-reads the whole file, starting at the current position.
-On end of file, it returns the empty string.
-</li>
-
-<li><b>"<code>*l</code>": </b>
-reads the next line skipping the end of line,
-returning <b>nil</b> on end of file.
-This is the default format.
-</li>
-
-<li><b>"<code>*L</code>": </b>
-reads the next line keeping the end of line (if present),
-returning <b>nil</b> on end of file.
-</li>
-
-<li><b><em>number</em>: </b>
-reads a string with up to this number of bytes,
-returning <b>nil</b> on end of file.
-If number is zero,
-it reads nothing and returns an empty string,
-or <b>nil</b> on end of file.
-</li>
-
-</ul>
-
-
-
-<p>
-<hr><h3><a name="pdf-file:seek"><code>file:seek ([whence [, offset]])</code></a></h3>
-
-
-<p>
-Sets and gets the file position,
-measured from the beginning of the file,
-to the position given by <code>offset</code> plus a base
-specified by the string <code>whence</code>, as follows:
-
-<ul>
-<li><b>"<code>set</code>": </b> base is position 0 (beginning of the file);</li>
-<li><b>"<code>cur</code>": </b> base is current position;</li>
-<li><b>"<code>end</code>": </b> base is end of file;</li>
-</ul><p>
-In case of success, <code>seek</code> returns the final file position,
-measured in bytes from the beginning of the file.
-If <code>seek</code> fails, it returns <b>nil</b>,
-plus a string describing the error.
-
-
-<p>
-The default value for <code>whence</code> is <code>"cur"</code>,
-and for <code>offset</code> is 0.
-Therefore, the call <code>file:seek()</code> returns the current
-file position, without changing it;
-the call <code>file:seek("set")</code> sets the position to the
-beginning of the file (and returns 0);
-and the call <code>file:seek("end")</code> sets the position to the
-end of the file, and returns its size.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:setvbuf"><code>file:setvbuf (mode [, size])</code></a></h3>
-
-
-<p>
-Sets the buffering mode for an output file.
-There are three available modes:
-
-<ul>
-
-<li><b>"<code>no</code>": </b>
-no buffering; the result of any output operation appears immediately.
-</li>
-
-<li><b>"<code>full</code>": </b>
-full buffering; output operation is performed only
-when the buffer is full or when
-you explicitly <code>flush</code> the file (see <a href="#pdf-io.flush"><code>io.flush</code></a>).
-</li>
-
-<li><b>"<code>line</code>": </b>
-line buffering; output is buffered until a newline is output
-or there is any input from some special files
-(such as a terminal device).
-</li>
-
-</ul><p>
-For the last two cases, <code>size</code>
-specifies the size of the buffer, in bytes.
-The default is an appropriate size.
-

-<hr><h3><a name="pdf-file:write"><code>file:write (···)</code></a></h3>
-
-
-<p>
-Writes the value of each of its arguments to <code>file</code>.
-The arguments must be strings or numbers.
-
-
-<p>
-In case of success, this function returns <code>file</code>.
-Otherwise it returns <b>nil</b> plus a string describing the error.

-
-<p>
-<hr><h3><a name="pdf-os.date"><code>os.date ([format [, time]])</code></a></h3>
-
-
-<p>
-Returns a string or a table containing date and time,
-formatted according to the given string <code>format</code>.
-
-
-<p>
-If the <code>time</code> argument is present,
-this is the time to be formatted
-(see the <a href="#pdf-os.time"><code>os.time</code></a> function for a description of this value).
-Otherwise, <code>date</code> formats the current time.
-
-
-<p>
-If <code>format</code> starts with '<code>!</code>',
-then the date is formatted in Coordinated Universal Time.
-After this optional character,
-if <code>format</code> is the string "<code>*t</code>",
-then <code>date</code> returns a table with the following fields:
-<code>year</code> (four digits), <code>month</code> (1–12), <code>day</code> (1–31),
-<code>hour</code> (0–23), <code>min</code> (0–59), <code>sec</code> (0–61),
-<code>wday</code> (weekday, Sunday is 1),
-<code>yday</code> (day of the year),
-and <code>isdst</code> (daylight saving flag, a boolean).
-This last field may be absent
-if the information is not available.
-
-
-<p>
-If <code>format</code> is not "<code>*t</code>",
-then <code>date</code> returns the date as a string,
-formatted according to the same rules as the ISO C function <code>strftime</code>.
-
-
-<p>
-When called without arguments,
-<code>date</code> returns a reasonable date and time representation that depends on
-the host system and on the current locale
-(that is, <code>os.date()</code> is equivalent to <code>os.date("%c")</code>).
-
-
-<p>
-On non-Posix systems,

-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.execute"><code>os.execute ([command])</code></a></h3>
-
-
-<p>
-This function is equivalent to the ISO C function <code>system</code>.
-It passes <code>command</code> to be executed by an operating system shell.
-Its first result is <b>true</b>
-if the command terminated successfully,
-or <b>nil</b> otherwise.
-After this first result
-the function returns a string and a number,
-as follows:
-
-<ul>
-
-<li><b>"<code>exit</code>": </b>
-the command terminated normally;
-the following number is the exit status of the command.
-</li>
-
-<li><b>"<code>signal</code>": </b>
-the command was terminated by a signal;
-the following number is the signal that terminated the command.
-</li>
-
-</ul>
-
-<p>
-When called without a <code>command</code>,
-<code>os.execute</code> returns a boolean that is true if a shell is available.

-Calls the ISO C function <code>exit</code> to terminate the host program.
-If <code>code</code> is <b>true</b>,
-the returned status is <code>EXIT_SUCCESS</code>;
-if <code>code</code> is <b>false</b>,
-the returned status is <code>EXIT_FAILURE</code>;
-if <code>code</code> is a number,
-the returned status is this number.
-The default value for <code>code</code> is <b>true</b>.

-<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
-
-
-<p>
-Sets the current locale of the program.
-<code>locale</code> is a system-dependent string specifying a locale;
-<code>category</code> is an optional string describing which category to change:
-<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
-<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
-the default category is <code>"all"</code>.
-The function returns the name of the new locale,
-or <b>nil</b> if the request cannot be honored.
-
-
-<p>
-If <code>locale</code> is the empty string,
-the current locale is set to an implementation-defined native locale.
-If <code>locale</code> is the string "<code>C</code>",
-the current locale is set to the standard C locale.
-
-
-<p>
-When called with <b>nil</b> as the first argument,
-this function only returns the name of the current locale
-for the given category.
-
-
-<p>
-This function may be not thread safe
-because of its reliance on C function <code>setlocale</code>.
-

-<p>
-<hr><h3><a name="pdf-os.time"><code>os.time ([table])</code></a></h3>
-
-
-<p>
-Returns the current time when called without arguments,
-or a time representing the date and time specified by the given table.
-This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
-and may have fields
-<code>hour</code> (default is 12),
-<code>min</code> (default is 0),
-<code>sec</code> (default is 0),
-and <code>isdst</code> (default is <b>nil</b>).
-For a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function.
-
-
-<p>
-The returned value is a number, whose meaning depends on your system.
-In POSIX, Windows, and some other systems,
-this number counts the number
-of seconds since some given start time (the "epoch").
-In other systems, the meaning is not specified,
-and the number returned by <code>time</code> can be used only as an argument to
-<a href="#pdf-os.date"><code>os.date</code></a> and <a href="#pdf-os.difftime"><code>os.difftime</code></a>.

-<hr><h3><a name="pdf-os.tmpname"><code>os.tmpname ()</code></a></h3>
-
-
-<p>
-Returns a string with a file name that can
-be used for a temporary file.
-The file must be explicitly opened before its use
-and explicitly removed when no longer needed.
-
-
-<p>
-On POSIX systems,
-this function also creates a file with that name,
-to avoid security risks.
-(Someone else might create the file with wrong permissions
-in the time between getting the name and creating the file.)
-You still have to open the file to use it
-and to remove it (even if you do not use it).
-
-
-<p>
-When possible,
-you may prefer to use <a href="#pdf-io.tmpfile"><code>io.tmpfile</code></a>,

-<h2>6.10 – <a name="6.10">The Debug Library</a></h2>
-
-<p>
-This library provides
-the functionality of the debug interface (<a href="#4.9">§4.9</a>) to Lua programs.
-You should exert care when using this library.
-Several of its functions
-violate basic assumptions about Lua code
-(e.g., that variables local to a function
-cannot be accessed from outside;
-that userdata metatables cannot be changed by Lua code;
-that Lua programs do not crash)
-and therefore can compromise otherwise secure code.
-Moreover, some functions in this library may be slow.
-
-
-<p>
-All functions in this library are provided
-inside the <a name="pdf-debug"><code>debug</code></a> table.
-All functions that operate over a thread
-have an optional first argument which is the
-thread to operate over.
-The default is always the current thread.
-
-
-<p>
-<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
-
-
-<p>
-Enters an interactive mode with the user,
-running each string that the user enters.
-Using simple commands and other debug facilities,
-the user can inspect global and local variables,
-change their values, evaluate expressions, and so on.
-A line containing only the word <code>cont</code> finishes this function,
-so that the caller continues its execution.
-
-
-<p>
-Note that commands for <code>debug.debug</code> are not lexically nested
-within any function and so have no direct access to local variables.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
-
-
-<p>
-Returns the current hook settings of the thread, as three values:
-the current hook function, the current hook mask,
-and the current hook count
-(as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] f [, what])</code></a></h3>
-
-
-<p>
-Returns a table with information about a function.
-You can give the function directly
-or you can give a number as the value of <code>f</code>,
-which means the function running at level <code>f</code> of the call stack
-of the given thread:
-level 0 is the current function (<code>getinfo</code> itself);
-level 1 is the function that called <code>getinfo</code>
-(except for tail calls, which do not count on the stack);
-and so on.
-If <code>f</code> is a number larger than the number of active functions,
-then <code>getinfo</code> returns <b>nil</b>.
-
-
-<p>
-The returned table can contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
-with the string <code>what</code> describing which fields to fill in.
-The default for <code>what</code> is to get all information available,
-except the table of valid lines.
-If present,
-the option '<code>f</code>'
-adds a field named <code>func</code> with the function itself.
-If present,
-the option '<code>L</code>'
-adds a field named <code>activelines</code> with the table of
-valid lines.
-
-
-<p>
-For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
-a table with a name for the current function,
-if a reasonable name can be found,
-and the expression <code>debug.getinfo(print)</code>
-returns a table with all available information
-about the <a href="#pdf-print"><code>print</code></a> function.

-<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] f, local)</code></a></h3>
-
-
-<p>
-This function returns the name and the value of the local variable
-with index <code>local</code> of the function at level <code>f</code> of the stack.
-This function accesses not only explicit local variables,
-but also parameters, temporaries, etc.
-
-
-<p>
-The first parameter or local variable has index 1, and so on,
-until the last active variable.
-Negative indices refer to vararg parameters;
--1 is the first vararg parameter.
-The function returns <b>nil</b> if there is no variable with the given index,
-and raises an error when called with a level out of range.
-(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
-
-
-<p>
-Variable names starting with '<code>(</code>' (open parenthesis)
-represent internal variables
-(loop control variables, temporaries, varargs, and C function locals).
-
-
-<p>
-The parameter <code>f</code> may also be a function.
-In that case, <code>getlocal</code> returns only the name of function parameters.

-<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
-
-
-<p>
-Sets the given function as a hook.
-The string <code>mask</code> and the number <code>count</code> describe
-when the hook will be called.
-The string mask may have any combination of the following characters,
-with the given meaning:
-
-<ul>
-<li><b>'<code>c</code>': </b> the hook is called every time Lua calls a function;</li>
-<li><b>'<code>r</code>': </b> the hook is called every time Lua returns from a function;</li>
-<li><b>'<code>l</code>': </b> the hook is called every time Lua enters a new line of code.</li>
-</ul><p>
-Moreover,
-with a <code>count</code> different from zero,
-the hook is called also after every <code>count</code> instructions.
-
-
-<p>
-When called without arguments,
-<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
-
-
-<p>
-When the hook is called, its first parameter is a string
-describing the event that has triggered its call:
-<code>"call"</code> (or <code>"tail call"</code>),
-<code>"return"</code>,
-<code>"line"</code>, and <code>"count"</code>.
-For line events,
-the hook also gets the new line number as its second parameter.
-Inside a hook,
-you can call <code>getinfo</code> with level 2 to get more information about
-the running function
-(level 0 is the <code>getinfo</code> function,
-and level 1 is the hook function).

-<h1>7 – <a name="7">Lua Standalone</a></h1>
-
-<p>
-Although Lua has been designed as an extension language,
-to be embedded in a host C program,
-it is also frequently used as a standalone language.
-An interpreter for Lua as a standalone language,
-called simply <code>lua</code>,
-is provided with the standard distribution.
-The standalone interpreter includes
-all standard libraries, including the debug library.
-Its usage is:
-
-<pre>
- lua [options] [script [args]]
-</pre><p>
-The options are:
-
-<ul>
-<li><b><code>-e <em>stat</em></code>: </b> executes string <em>stat</em>;</li>
-<li><b><code>-l <em>mod</em></code>: </b> "requires" <em>mod</em>;</li>
-<li><b><code>-i</code>: </b> enters interactive mode after running <em>script</em>;</li>
-<li><b><code>-v</code>: </b> prints version information;</li>
-<li><b><code>-E</code>: </b> ignores environment variables;</li>
-<li><b><code>--</code>: </b> stops handling options;</li>
-<li><b><code>-</code>: </b> executes <code>stdin</code> as a file and stops handling options.</li>
-</ul><p>
-After handling its options, <code>lua</code> runs the given <em>script</em>,
-passing to it the given <em>args</em> as string arguments.
-When called without arguments,
-<code>lua</code> behaves as <code>lua -v -i</code>
-when the standard input (<code>stdin</code>) is a terminal,
-and as <code>lua -</code> otherwise.
-
-
-<p>
-When called without option <code>-E</code>,
-the interpreter checks for an environment variable <a name="pdf-LUA_INIT_5_2"><code>LUA_INIT_5_2</code></a>
-(or <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a> if it is not defined)
-before running any argument.
-If the variable content has the format <code>@<em>filename</em></code>,
-then <code>lua</code> executes the file.
-Otherwise, <code>lua</code> executes the string itself.
-
-
-<p>
-When called with option <code>-E</code>,
-besides ignoring <code>LUA_INIT</code>,
-Lua also ignores
-the values of <code>LUA_PATH</code> and <code>LUA_CPATH</code>,
-setting the values of
-<a href="#pdf-package.path"><code>package.path</code></a> and <a href="#pdf-package.cpath"><code>package.cpath</code></a>
-with the default paths defined in <code>luaconf.h</code>.
-
-
-<p>
-All options are handled in order, except <code>-i</code> and <code>-E</code>.
-For instance, an invocation like
-
-<pre>
- $ lua -e'a=1' -e 'print(a)' script.lua
-</pre><p>
-will first set <code>a</code> to 1, then print the value of <code>a</code>,
-and finally run the file <code>script.lua</code> with no arguments.
-(Here <code>$</code> is the shell prompt. Your prompt may be different.)
-
-
-<p>
-Before starting to run the script,
-<code>lua</code> collects all arguments in the command line
-in a global table called <code>arg</code>.
-The script name is stored at index 0,
-the first argument after the script name goes to index 1,
-and so on.
-Any arguments before the script name
-(that is, the interpreter name plus the options)
-go to negative indices.
-For instance, in the call
-
-<pre>
- $ lua -la b.lua t1 t2
-</pre><p>
-the interpreter first runs the file <code>a.lua</code>,
-then creates a table
-
-<pre>
- arg = { [-2] = "lua", [-1] = "-la",
- [0] = "b.lua",
- [1] = "t1", [2] = "t2" }
-</pre><p>
-and finally runs the file <code>b.lua</code>.
-The script is called with <code>arg[1]</code>, <code>arg[2]</code>, ...
-as arguments;
-it can also access these arguments with the vararg expression '<code>...</code>'.
-
-
-<p>
-In interactive mode,
-if you write an incomplete statement,
-the interpreter waits for its completion
-by issuing a different prompt.
-
-
-<p>
-In case of unprotected errors in the script,
-the interpreter reports the error to the standard error stream.
-If the error object is a string,
-the interpreter adds a stack traceback to it.
-Otherwise, if the error object has a metamethod <code>__tostring</code>,
-the interpreter calls this metamethod to produce the final message.
-Finally, if the error object is <b>nil</b>,
-the interpreter does not report the error.
-
-
-<p>
-When finishing normally,
-the interpreter closes its main Lua state
-(see <a href="#lua_close"><code>lua_close</code></a>).
-The script can avoid this step by
-calling <a href="#pdf-os.exit"><code>os.exit</code></a> to terminate.
-
-
-<p>
-To allow the use of Lua as a
-script interpreter in Unix systems,
-the standalone interpreter skips
-the first line of a chunk if it starts with <code>#</code>.
-Therefore, Lua scripts can be made into executable programs
-by using <code>chmod +x</code> and the <code>#!</code> form,
-as in
-
-<pre>
- #!/usr/local/bin/lua
-</pre><p>
-(Of course,
-the location of the Lua interpreter may be different in your machine.
-If <code>lua</code> is in your <code>PATH</code>,
-then
-
-<pre>
- #!/usr/bin/env lua
-</pre><p>
-is a more portable solution.)

-<h1>8 – <a name="8">Incompatibilities with the Previous Version</a></h1>
-
-<p>
-Here we list the incompatibilities that you may find when moving a program
-from Lua 5.1 to Lua 5.2.
-You can avoid some incompatibilities by compiling Lua with
-appropriate options (see file <code>luaconf.h</code>).
-However,
-all these compatibility options will be removed in the next version of Lua.
-Similarly,
-all features marked as deprecated in Lua 5.1
-have been removed in Lua 5.2.
-
-
-
-<h2>8.1 – <a name="8.1">Changes in the Language</a></h2>
-<ul>
-
-<li>
-The concept of <em>environment</em> changed.
-Only Lua functions have environments.
-To set the environment of a Lua function,
-use the variable <code>_ENV</code> or the function <a href="#pdf-load"><code>load</code></a>.
-
-
-<p>
-C functions no longer have environments.
-Use an upvalue with a shared table if you need to keep
-shared state among several C functions.
-(You may use <a href="#luaL_setfuncs"><code>luaL_setfuncs</code></a> to open a C library
-with all functions sharing a common upvalue.)
-
-
-<p>
-To manipulate the "environment" of a userdata
-(which is now called user value),
-use the new functions
-<a href="#lua_getuservalue"><code>lua_getuservalue</code></a> and <a href="#lua_setuservalue"><code>lua_setuservalue</code></a>.
-</li>
-
-<li>
-Lua identifiers cannot use locale-dependent letters.
-</li>
-
-<li>
-Doing a step or a full collection in the garbage collector
-does not restart the collector if it has been stopped.
-</li>
-
-<li>
-Weak tables with weak keys now perform like <em>ephemeron tables</em>.
-</li>
-
-<li>
-The event <em>tail return</em> in debug hooks was removed.
-Instead, tail calls generate a special new event,
-<em>tail call</em>, so that the debugger can know that
-there will not be a corresponding return event.
-</li>
-
-<li>
-Equality between function values has changed.
-Now, a function definition may not create a new value;
-it may reuse some previous value if there is no
-observable difference to the new function.
-</li>
-
-</ul>
-
-
-
-
-<h2>8.2 – <a name="8.2">Changes in the Libraries</a></h2>
-<ul>
-
-<li>
-Function <code>module</code> is deprecated.
-It is easy to set up a module with regular Lua code.
-Modules are not expected to set global variables.
-</li>
-
-<li>
-Functions <code>setfenv</code> and <code>getfenv</code> were removed,
-because of the changes in environments.
-</li>
-
-<li>
-Function <code>math.log10</code> is deprecated.
-Use <a href="#pdf-math.log"><code>math.log</code></a> with 10 as its second argument, instead.
-</li>
-
-<li>
-Function <code>loadstring</code> is deprecated.
-Use <code>load</code> instead; it now accepts string arguments
-and are exactly equivalent to <code>loadstring</code>.
-</li>
-
-<li>
-Function <code>table.maxn</code> is deprecated.
-Write it in Lua if you really need it.
-</li>
-
-<li>
-Function <code>os.execute</code> now returns <b>true</b> when command
-terminates successfully and <b>nil</b> plus error information
-otherwise.
-</li>
-
-<li>
-Function <code>unpack</code> was moved into the table library
-and therefore must be called as <a href="#pdf-table.unpack"><code>table.unpack</code></a>.
-</li>
-
-<li>
-Character class <code>%z</code> in patterns is deprecated,
-as now patterns may contain '<code>\0</code>' as a regular character.
-</li>
-
-<li>
-The table <code>package.loaders</code> was renamed <code>package.searchers</code>.
-</li>
-
-<li>
-Lua does not have bytecode verification anymore.
-So, all functions that load code
-(<a href="#pdf-load"><code>load</code></a> and <a href="#pdf-loadfile"><code>loadfile</code></a>)
-are potentially insecure when loading untrusted binary data.
-(Actually, those functions were already insecure because
-of flaws in the verification algorithm.)
-When in doubt,
-use the <code>mode</code> argument of those functions
-to restrict them to loading textual chunks.
-</li>
-
-<li>
-The standard paths in the official distribution may
-change between versions.
-</li>
-
-</ul>
-
-
-
-
-<h2>8.3 – <a name="8.3">Changes in the API</a></h2>
-<ul>
-
-<li>
-Pseudoindex <code>LUA_GLOBALSINDEX</code> was removed.
-You must get the global environment from the registry
-(see <a href="#4.5">§4.5</a>).
-</li>
-
-<li>
-Pseudoindex <code>LUA_ENVIRONINDEX</code>
-and functions <code>lua_getfenv</code>/<code>lua_setfenv</code>
-were removed,
-as C functions no longer have environments.
-</li>
-
-<li>
-Function <code>luaL_register</code> is deprecated.
-Use <a href="#luaL_setfuncs"><code>luaL_setfuncs</code></a> so that your module does not create globals.
-(Modules are not expected to set global variables anymore.)
-</li>
-
-<li>
-The <code>osize</code> argument to the allocation function
-may not be zero when creating a new block,
-that is, when <code>ptr</code> is <code>NULL</code>
-(see <a href="#lua_Alloc"><code>lua_Alloc</code></a>).
-Use only the test <code>ptr == NULL</code> to check whether
-the block is new.
-</li>
-
-<li>
-Finalizers (<code>__gc</code> metamethods) for userdata are called in the
-reverse order that they were marked for finalization,
-not that they were created (see <a href="#2.5.1">§2.5.1</a>).
-(Most userdata are marked immediately after they are created.)
-Moreover,
-if the metatable does not have a <code>__gc</code> field when set,
-the finalizer will not be called,
-even if it is set later.
-</li>
-
-<li>
-<code>luaL_typerror</code> was removed.
-Write your own version if you need it.
-</li>
-
-<li>
-Function <code>lua_cpcall</code> is deprecated.
-You can simply push the function with <a href="#lua_pushcfunction"><code>lua_pushcfunction</code></a>
-and call it with <a href="#lua_pcall"><code>lua_pcall</code></a>.
-</li>
-
-<li>
-Functions <code>lua_equal</code> and <code>lua_lessthan</code> are deprecated.
-Use the new <a href="#lua_compare"><code>lua_compare</code></a> with appropriate options instead.
-</li>
-
-<li>
-Function <code>lua_objlen</code> was renamed <a href="#lua_rawlen"><code>lua_rawlen</code></a>.
-</li>
-
-<li>
-Function <a href="#lua_load"><code>lua_load</code></a> has an extra parameter, <code>mode</code>.
-Pass <code>NULL</code> to simulate the old behavior.
-</li>
-
-<li>
-Function <a href="#lua_resume"><code>lua_resume</code></a> has an extra parameter, <code>from</code>.
-Pass <code>NULL</code> or the thread doing the call.
-</li>
-
-</ul>

-<H2><A NAME="about">About Lua</A></H2>
-
-<P>
-Lua is a powerful, fast, lightweight, embeddable scripting language
-developed by a
-<A HREF="http://www.lua.org/authors.html">team</A>
-at
-<A HREF="http://www.puc-rio.br/">PUC-Rio</A>,
-the Pontifical Catholic University of Rio de Janeiro in Brazil.
-Lua is
-<A HREF="#license">free software</A>
-used in many products and projects around the world.
-
-<P>
-Lua's
-<A HREF="http://www.lua.org/">official web site</A>
-provides complete information
-about Lua,
-including
-an
-<A HREF="http://www.lua.org/about.html">executive summary</A>
-and
-updated
-<A HREF="http://www.lua.org/docs.html">documentation</A>,
-especially the
-<A HREF="http://www.lua.org/manual/5.2/">reference manual</A>,
-which may differ slightly from the
-<A HREF="contents.html">local copy</A>
-distributed in this package.
-
-<H2><A NAME="install">Installing Lua</A></H2>
-
-<P>
-Lua is distributed in
-<A HREF="http://www.lua.org/ftp/">source</A>
-form.
-You need to build it before using it.
-Building Lua should be straightforward
-because
-Lua is implemented in pure ANSI C and compiles unmodified in all known
-platforms that have an ANSI C compiler.
-Lua also compiles unmodified as C++.
-The instructions given below for building Lua are for Unix-like platforms.
-See also
-<A HREF="#other">instructions for other systems</A>
-and
-<A HREF="#customization">customization options</A>.
-
-<P>
-If you don't have the time or the inclination to compile Lua yourself,
-get a binary from
-<A HREF="http://lua-users.org/wiki/LuaBinaries">LuaBinaries</A>.
-Try also
-<A HREF="http://luadist.org/">LuaDist</A>,
-a multi-platform distribution of Lua that includes batteries.
-
-<H3>Building Lua</H3>
-
-<P>
-In most Unix-like platforms, simply do "<KBD>make</KBD>" with a suitable target.
-Here are the details.
-
-<OL>
-<LI>
-Open a terminal window and move to
-the top-level directory, which is named <TT>lua-5.2.x</TT>.
-The <TT>Makefile</TT> there controls both the build process and the installation process.
-<P>
-<LI>
- Do "<KBD>make</KBD>" and see if your platform is listed.
- The platforms currently supported are:
-<P>
-<P CLASS="display">
- aix ansi bsd freebsd generic linux macosx mingw posix solaris
-</P>
-<P>
- If your platform is listed, just do "<KBD>make xxx</KBD>", where xxx
- is your platform name.
-<P>
- If your platform is not listed, try the closest one or posix, generic,
- ansi, in this order.
-<P>
-<LI>
-The compilation takes only a few moments
-and produces three files in the <TT>src</TT> directory:
-lua (the interpreter),
-luac (the compiler),
-and liblua.a (the library).
-<P>
-<LI>
- To check that Lua has been built correctly, do "<KBD>make test</KBD>"
- after building Lua. This will run the interpreter and print its version.
-</OL>
-<P>
-If you're running Linux and get compilation errors,
-make sure you have installed the <TT>readline</TT> development package
-(which is probably named <TT>libreadline-dev</TT> or <TT>readline-devel</TT>).
-If you get link errors after that,
-then try "<KBD>make linux MYLIBS=-ltermcap</KBD>".
-
-<H3>Installing Lua</H3>
-<P>
- Once you have built Lua, you may want to install it in an official
- place in your system. In this case, do "<KBD>make install</KBD>". The official
- place and the way to install files are defined in the <TT>Makefile</TT>. You'll
- probably need the right permissions to install files.
-
-<P>
- To build and install Lua in one step, do "<KBD>make xxx install</KBD>",
- where xxx is your platform name.
-
-<P>
- To install Lua locally, do "<KBD>make local</KBD>".
- This will create a directory <TT>install</TT> with subdirectories
- <TT>bin</TT>, <TT>include</TT>, <TT>lib</TT>, <TT>man</TT>, <TT>share</TT>,
- and install Lua as listed below.
-
- To install Lua locally, but in some other directory, do
- "<KBD>make install INSTALL_TOP=xxx</KBD>", where xxx is your chosen directory.
- The installation starts in the <TT>src</TT> and <TT>doc</TT> directories,
- so take care if <TT>INSTALL_TOP</TT> is not an absolute path.
-
-<DL CLASS="display">
-<DT>
- bin:
-<DD>
- lua luac
-<DT>
- include:
-<DD>
- lua.h luaconf.h lualib.h lauxlib.h lua.hpp
-<DT>
- lib:
-<DD>
- liblua.a
-<DT>
- man/man1:
-<DD>
- lua.1 luac.1
-</DL>
-
-<P>
- These are the only directories you need for development.
- If you only want to run Lua programs,
- you only need the files in <TT>bin</TT> and <TT>man</TT>.
- The files in <TT>include</TT> and <TT>lib</TT> are needed for
- embedding Lua in C or C++ programs.
-
-<H3><A NAME="customization">Customization</A></H3>
-<P>
- Three kinds of things can be customized by editing a file:
-<UL>
- <LI> Where and how to install Lua — edit <TT>Makefile</TT>.
- <LI> How to build Lua — edit <TT>src/Makefile</TT>.
- <LI> Lua features — edit <TT>src/luaconf.h</TT>.
-</UL>
-
-<P>
- You don't actually need to edit the Makefiles because you may set the
- relevant variables in the command line when invoking make.
- Nevertheless, it's probably best to edit and save the Makefiles to
- record the changes you've made.
-
-<P>
- On the other hand, if you need to customize some Lua features, you'll need
- to edit <TT>src/luaconf.h</TT> before building and installing Lua.
- The edited file will be the one installed, and
- it will be used by any Lua clients that you build, to ensure consistency.
- Further customization is available to experts by editing the Lua sources.
-
-<P>
- We strongly recommend that you enable dynamic loading in <TT>src/luaconf.h</TT>.
- This is done automatically for all platforms listed above that have
- this feature and also for Windows.
-
-<H3><A NAME="other">Building Lua on other systems</A></H3>
-
-<P>
- If you're not using the usual Unix tools, then the instructions for
- building Lua depend on the compiler you use. You'll need to create
- projects (or whatever your compiler uses) for building the library,
- the interpreter, and the compiler, as follows:
-
-<DL CLASS="display">
-<DT>
-library:
-<DD>
-lapi.c lcode.c lctype.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
-lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c
-ltm.c lundump.c lvm.c lzio.c
-lauxlib.c lbaselib.c lbitlib.c lcorolib.c ldblib.c liolib.c
-lmathlib.c loslib.c lstrlib.c ltablib.c loadlib.c linit.c
-<DT>
-interpreter:
-<DD>
- library, lua.c
-<DT>
-compiler:
-<DD>
- library, luac.c
-</DL>
-
-<P>
- To use Lua as a library in your own programs you'll need to know how to
- create and use libraries with your compiler. Moreover, to dynamically load
- C libraries for Lua you'll need to know how to create dynamic libraries
- and you'll need to make sure that the Lua API functions are accessible to
- those dynamic libraries — but <EM>don't</EM> link the Lua library
- into each dynamic library. For Unix, we recommend that the Lua library
- be linked statically into the host program and its symbols exported for
- dynamic linking; <TT>src/Makefile</TT> does this for the Lua interpreter.
- For Windows, we recommend that the Lua library be a DLL.
- In all cases, the compiler luac should be linked statically.
-
-<P>
- As mentioned above, you may edit <TT>src/luaconf.h</TT> to customize
- some features before building Lua.
-
-<H2><A NAME="changes">Changes since Lua 5.1</A></H2>

-** Open upvalues are not subject to independent garbage collection. They

-** when traversing the respective threads, but the thread may already be
-** dead, while the upvalue is still accessible through closures.)
-**
-** Objects with finalizers are kept in the list g->finobj.

+an input is treated as a bits stream. Every input byte is "buffered" in a larger integer, as its lower bits (from right).
Every output value is taken from its higher (left) bits. In a special case of bits-per-component equal 1, we buffer all
pixel bits and use XOR to compute bits difference between pixels. I've excerpted that trick from poppler, but I'm not
really sure if it works any better, especially when the number of components per pixel is 1. In that case we do a hard
bit-by-bit work anyway.
-Predictor codecs state keeps a notion of surrounding pixels. PNG predictors uses left, up and upleft
-pixel data, while TIFF predictor (2) only needs the previous (left) pixel. Important to note that PNG
-predictors always work on bytes, no matter of color-depth (bits per component), while TIFF predictor
-works on pixel components, which not necessarily fits into a complete byte. However, for PNG predictor
-the size of a pixel still matters, because 'left' and 'upleft' refers to a corresponding pixel byte,
-not necessarily previous byte.

In PNG prediction, we record every pixel byte (in decoded form) in state->rowsave. At the end of a scanline
we copy state->rowsave to state->rowup, so that in the next scanline we can access up-pixel byte.
Left pixel byte is accessed as state->rowsave (the byte recently stored or virtual left edge byte \0).

+% tangle.ch for C compilation with web2c.
+%
+% 10/9/82 (HT) Original version
+% 11/29 (HT) New version, with conversion to lowercase handled properly
+% Also, new control sequence:
+% @=...text...@> Put ...text... verbatim on a line
+% by itself in the Pascal output.
+% (argument must fit on one line)
+% This control sequence facilitates putting #include "gcons.h"
+% (for example) in files meant for the pc compiler.
+% Also, changed command line usage, so that the absence of a
+% change file implies no change file, rather than one with the
+% same name as the web file, with .ch at the end.
+% 1/15/83 (HT) Changed to work with version 1.2, which incorporates the
+% above change (though unbundling the output line breaking),
+% so mainly had to remove stuff.
+% 2/17 (HT) Fixed bug that caused 0-9 in identifiers to be converted to
+% Q-Y on output.
+% 3/18 (HT) Brought up to work with Version 1.5. Added -r command line
+% flag to cause a .rpl file to be written with all the lines
+% of the .web file that were replaced because of the .ch file
+% (useful for comparing with previous .rpl files, to see if a
+% change file will still work with a new version of a .web file)
+% Also, made it write a newline just before exit.
+% 4/12 (PC) Merged with Pavel's version, including adding a call to exit()
+% at the end depending upon the value of history.
+% 4/16 (PC) Brought up to date with version 1.5 released April, 1983.
+% 6/28 (HWT) Brought up to date with version 1.7 released June, 1983.
+% With new change file format, the -r option is now unnecessary.
+% 7/17 (HWT) Brought up to date with version 2.0 released July, 1983.
+% 12/18/83 (ETM) Brought up to date with version 2.5 released November, 1983.
+% 11/07/84 (ETM) Brought up to date with version 2.6.
+% 12/15/85 (ETM) Brought up to date with version 2.8.
+% 03/07/88 (ETM) Converted for use with WEB2C
+% 01/02/89 (PAM) Cosmetic upgrade to version 2.9
+% 11/30/89 (KB) Version 4.

+@* Introduction.
+This program converts a \.{WEB} file to a \PASCAL\ file. It was written
+by D. E. Knuth in September, 1981; a somewhat similar {\mc SAIL} program had
+been developed in March, 1979. Since this program describes itself, a
+bootstrapping process involving hand-translation had to be used to get started.
+
+For large \.{WEB} files one should have a large memory, since \.{TANGLE} keeps
+all the \PASCAL\ text in memory (in an abbreviated form). The program uses
+a few features of the local \PASCAL\ compiler that may need to be changed in
+other installations:
+
+\yskip\item{1)} Case statements have a default.
+\item{2)} Input-output routines may need to be adapted for use with a particular
+character set and/or for printing messages on the user's terminal.
+
+\yskip\noindent
+These features are also present in the \PASCAL\ version of \TeX, where they
+are used in a similar (but more complex) way. System-dependent portions
+of \.{TANGLE} can be identified by looking at the entries for `system
+dependencies' in the index below.
+@!@^system dependencies@>
+
+The ``banner line'' defined here should be changed whenever \.{TANGLE}
+is modified.
+
+@d banner=='This is TANGLE, Version 4.5'
+
+@ The program begins with a fairly normal header, made up of pieces that
+@^system dependencies@>
+will mostly be filled in later. The \.{WEB} input comes from files |web_file|
+and |change_file|, the \PASCAL\ output goes to file |Pascal_file|,
+and the string pool output goes to file |pool|.
+
+If it is necessary to abort the job because of a fatal error, the program
+calls the `|jump_out|' procedure, which goes to the label |end_of_TANGLE|.

+
+@ The \PASCAL\ compiler used to develop this system has ``compiler
+directives'' that can appear in comments whose first character is a dollar sign.
+In production versions of \.{TANGLE} these directives tell the compiler that
+@^system dependencies@>
+it is safe to avoid range checks and to leave out the extra code it inserts
+for the \PASCAL\ debugger's benefit, although interrupts will occur if
+there is arithmetic overflow.

+
+@ Labels are given symbolic names by the following definitions. We insert
+the label `|exit|:' just before the `\ignorespaces|end|\unskip' of a
+procedure in which we have used the `|return|' statement defined below;
+the label `|restart|' is occasionally used at the very beginning of a
+procedure; and the label `|reswitch|' is occasionally used just prior to
+a \&{case} statement in which some cases change the conditions and we wish to
+branch to the newly applicable case.
+Loops that are set up with the \&{loop} construction defined below are
+commonly exited by going to `|done|' or to `|found|' or to `|not_found|',
+and they are sometimes repeated by going to `|continue|'.
+
+@d exit=10 {go here to leave a procedure}
+@d restart=20 {go here to start a procedure again}
+@d reswitch=21 {go here to start a case statement again}
+@d continue=22 {go here to resume a loop}
+@d done=30 {go here to exit a loop}
+@d found=31 {go here when you've found it}
+@d not_found=32 {go here when you've found something else}
+
+@ Here are some macros for common programming idioms.
+
+@d incr(#) == #:=#+1 {increase a variable by unity}
+@d decr(#) == #:=#-1 {decrease a variable by unity}
+@d loop == @+ while true do@+ {repeat over and over until a |goto| happens}
+@d do_nothing == {empty statement}
+@d return == goto exit {terminate a procedure call}
+@f return == nil
+@f loop == xclause
+
+@ We assume that |case| statements may include a default case that applies
+if no matching label is found. Thus, we shall use constructions like

+|endcases|\cr}}$$
+since most \PASCAL\ compilers have plugged this hole in the language by
+incorporating some sort of default mechanism. For example, the compiler
+used to develop \.{WEB} and \TeX\ allows `|others|:' as a default label,
+and other \PASCAL s allow syntaxes like `\ignorespaces|else|\unskip' or
+`\&{otherwise}' or `\\{otherwise}:', etc. The definitions of |othercases|
+and |endcases| should be changed to agree with local conventions. (Of
+course, if no default mechanism is available, the |case| statements of
+this program must be extended by listing all remaining cases. The author
+would have taken the trouble to modify \.{TANGLE} so that such extensions
+were done automatically, if he had not wanted to encourage \PASCAL\
+compiler writers to make this important change in \PASCAL, where it belongs.)

+at least one error was found; |fatal_message| means that the program

+
+@* The character set.
+One of the main goals in the design of \.{WEB} has been to make it readily
+portable between a wide variety of computers. Yet \.{WEB} by its very
+nature must use a greater variety of characters than most computer
+programs deal with, and character encoding is one of the areas in which
+existing machines differ most widely from each other.
+
+To resolve this problem, all input to \.{WEAVE} and \.{TANGLE} is converted
+to an internal eight-bit code that is essentially standard ASCII, the ``American
+Standard Code for Information Interchange.'' The conversion is done
+immediately when each character is read in. Conversely, characters are
+converted from ASCII to the user's external representation just before
+they are output. (The original ASCII code was seven bits only; \.{WEB} now

+@ The original \PASCAL\ compiler was designed in the late 60s, when six-bit
+character sets were common, so it did not make provision for lowercase
+letters. Nowadays, of course, we need to deal with both capital and small
+letters in a convenient way, so \.{WEB} assumes that it is being used
+with a \PASCAL\ whose character set contains at least the characters of
+standard ASCII as listed above. Some \PASCAL\ compilers use the original
+name |char| for the data type associated with the characters in text files,
+while other \PASCAL s consider |char| to be a 64-element subrange of a larger
+data type that has some other name.
+
+In order to accommodate this difference, we shall use the name |text_char|
+to stand for the data type of the characters in the input and output
+files. We shall also assume that |text_char| consists of the elements
+|chr(first_text_char)| through |chr(last_text_char)|, inclusive. The

+character \.A in the external (|char|) code. Note that it would be quite
+incorrect to say \.{xchr[@@\'101]:="A"}, because |"A"| is a constant of

+here, giving an |xchr| equivalent to whatever characters the users of
+\.{WEB} are allowed to have in their input files, provided that unsuitable
+characters do not correspond to special codes like |carriage_return|
+that are listed above.
+
+(The present file \.{TANGLE.WEB} does not contain any of the non-ASCII
+characters, because it is intended to be used with all implementations of

+@* Data structures.
+Most of the user's \PASCAL\ code is packed into eight-bit integers
+in two large arrays called |byte_mem| and |tok_mem|.
+The |byte_mem| array holds the names of identifiers, strings, and modules;
+the |tok_mem| array holds the replacement texts
+for macros and modules. Allocation is sequential, since things are deleted only
+during Phase II, and only in a last-in-first-out manner.
+
+Auxiliary arrays |byte_start| and |tok_start| are used as directories to
+|byte_mem| and |tok_mem|, and the |link|, |ilk|, |equiv|, and |text_link|
+arrays give further information about names. These auxiliary arrays
+consist of sixteen-bit items.
+
+@<Types...@>=
+@!eight_bits=0..255; {unsigned one-byte quantity}
+@!sixteen_bits=0..65535; {unsigned two-byte quantity}
+
+@ \.{TANGLE} has been designed to avoid the need for indices that are more
+than sixteen bits wide, so that it can be used on most computers. But
+there are programs that need more than 65536 tokens, and some programs
+even need more than 65536 bytes; \TeX\ is one of these. To get around
+this problem, a slight complication has been added to the data structures:
+|byte_mem| and |tok_mem| are two-dimensional arrays, whose first index is
+either 0 or 1. (For generality, the first index is actually allowed to run
+between 0 and |ww-1| in |byte_mem|, or between 0 and |zz-1| in |tok_mem|,
+where |ww| and |zz| are set to 2 and~3; the program will work for any
+positive values of |ww| and |zz|, and it can be simplified in obvious ways
+if |ww=1| or |zz=1|.)
+
+@d ww=2 {we multiply the byte capacity by approximately this amount}
+@d zz=3 {we multiply the token capacity by approximately this amount}
+
+@<Globals...@>=
+@!byte_mem: packed array [0..ww-1,0..max_bytes] of ASCII_code;
+ {characters of names}
+@!tok_mem: packed array [0..zz-1,0..max_toks] of eight_bits; {tokens}
+@!byte_start: array [0..max_names] of sixteen_bits; {directory into |byte_mem|}
+@!tok_start: array [0..max_texts] of sixteen_bits; {directory into |tok_mem|}
+@!link: array [0..max_names] of sixteen_bits; {hash table or tree links}
+@!ilk: array [0..max_names] of sixteen_bits; {type codes or tree links}
+@!equiv: array [0..max_names] of sixteen_bits; {info corresponding to names}
+@!text_link: array [0..max_texts] of sixteen_bits; {relates replacement texts}
+
+@ The names of identifiers are found by computing a hash address |h| and
+then looking at strings of bytes signified by |hash[h]|, |link[hash[h]]|,
+|link[link[hash[h]]]|, \dots, until either finding the desired name
+or encountering a zero.
+
+A `|name_pointer|' variable, which signifies a name, is an index into
+|byte_start|. The actual sequence of characters in the name pointed to by
+|p| appears in positions |byte_start[p]| to |byte_start[p+ww]-1|, inclusive,
+in the segment of |byte_mem| whose first index is |p mod ww|. Thus, when
+|ww=2| the even-numbered name bytes appear in |byte_mem[0,@t$*$@>]|
+and the odd-numbered ones appear in |byte_mem[1,@t$*$@>]|.
+The pointer 0 is used for undefined module names; we don't
+want to use it for the names of identifiers, since 0 stands for a null
+pointer in a linked list.
+
+Strings are treated like identifiers; the first character (a double-quote)
+distinguishes a string from an alphabetic name, but for \.{TANGLE}'s purposes
+strings behave like numeric macros. (A `string' here refers to the
+strings delimited by double-quotes that \.{TANGLE} processes. \PASCAL\
+string constants delimited by single-quote marks are not given such special
+treatment; they simply appear as sequences of characters in the \PASCAL\
+texts.) The total number of strings in the string

+@ Replacement texts are stored in |tok_mem|, using similar conventions.
+A `|text_pointer|' variable is an index into |tok_start|, and the
+replacement text that corresponds to |p| runs from positions
+|tok_start[p]| to |tok_start[p+zz]-1|, inclusive, in the segment of
+|tok_mem| whose first index is |p mod zz|. Thus, when |zz=2| the
+even-numbered replacement texts appear in |tok_mem[0,@t$*$@>]| and the
+odd-numbered ones appear in |tok_mem[1,@t$*$@>]|. Furthermore,
+|text_link[p]| is used to connect pieces of text that have the same name,
+as we shall see later. The pointer 0 is used for undefined replacement
+texts.
+
+The first position of |tok_mem[z,@t$*$@>]| that is unoccupied by
+replacement text is called |tok_ptr[z]|, and the first unused location of
+|tok_start| is called |text_ptr|. We usually have the identity

+is used to check whether any two of them agree in their first |unambig_length|
+characters after underline symbols are removed and lowercase letters are
+changed to uppercase.
+
+\yskip\hang |numeric| identifiers have been defined to be numeric macros;
+their |equiv| value contains the corresponding numeric value plus $2^{15}$.
+Strings are treated as numeric macros.
+
+\yskip\hang |simple| identifiers have been defined to be simple macros;
+their |equiv| value points to the corresponding replacement text.
+
+\yskip\hang |parametric| identifiers have been defined to be parametric macros;
+like simple identifiers, their |equiv| value points to the replacement text.
+

+@d numeric=1 {numeric macros and strings have |numeric| ilk}
+@d simple=2 {simple macros have |simple| ilk}
+@d parametric=3 {parametric macros have |parametric| ilk}
+
+@ The names of modules are stored in |byte_mem| together
+with the identifier names, but a hash table is not used for them because
+\.{TANGLE} needs to be able to recognize a module name when given a prefix of
+that name. A conventional binary seach tree is used to retrieve module names,
+with fields called |llink| and |rlink| in place of |link| and |ilk|. The
+root of this tree is |rlink[0]|. If |p| is a pointer to a module name,
+|equiv[p]| points to its replacement text, just as in simple and parametric
+macros, unless this replacement text has not yet been defined (in which case
+|equiv[p]=0|).

+end;
+
+@* Searching for identifiers.
+The hash table described above is updated by the |id_lookup| procedure,
+which finds a given identifier and returns a pointer to its index in
+|byte_start|. If the identifier was not already present, it is inserted with
+a given |ilk| code; and an error message is printed if the identifier is being
+doubly defined.
+
+Because of the way \.{TANGLE}'s scanning mechanism works, it is most convenient
+to let |id_lookup| search for an identifier that is present in the |buffer|
+array. Two other global variables specify its position in the buffer: the
+first character is |buffer[id_first]|, and the last is |buffer[id_loc-1]|.
+Furthermore, if the identifier is really a string, the global variable
+|double_chars| tells how many of the characters in the buffer appear
+twice (namely \.{@@@@} and \.{""}), since this additional information makes
+it easy to calculate the true length of the string. The final double-quote
+of the string is not included in its ``identifier,'' but the first one is,
+so the string length is |id_loc-id_first-double_chars-1|.
+
+We have mentioned that |normal| identifiers belong to two hash tables,
+one for their true names as they appear in the \.{WEB} file and the other
+when they have been reduced to their first |unambig_length| characters.
+The hash tables are kept by the method of simple chaining, where the
+heads of the individual lists appear in the |hash| and |chop_hash| arrays.
+If |h| is a hash code, the primary hash table list starts at |hash[h]| and
+proceeds through |link| pointers; the secondary hash table list starts at
+|chop_hash[h]| and proceeds through |equiv| pointers. Of course, the same
+identifier will probably have two different values of |h|.
+
+The |id_lookup| procedure uses an auxiliary array called |chopped_id| to
+contain up to |unambig_length| characters of the current identifier, if
+it is necessary to compute the secondary hash code. (This array could be
+declared local to |id_lookup|, but in general we are making all array
+declarations global in this program, because some compilers and some machine
+architectures make dynamic array allocation inefficient.)

+@* Stacks for output.
+Let's make sure that our data structures contain enough information to
+produce the entire \PASCAL\ program as desired, by working next on the
+algorithms that actually do produce that program.
+
+@ The output process uses a stack to keep track of what is going on at
+different ``levels'' as the macros are being expanded.
+Entries on this stack have five parts:
+
+\yskip\hang |end_field| is the |tok_mem| location where the replacement
+text of a particular level will end;
+
+\hang |byte_field| is the |tok_mem| location from which the next token
+on a particular level will be read;
+
+\hang |name_field| points to the name corresponding to a particular level;
+
+\hang |repl_field| points to the replacement text currently being read
+at a particular level;
+
+\hang |mod_field| is the module number, or zero if this is a macro.
+
+\yskip\noindent The current values of these five quantities are referred to
+quite frequently, so they are stored in a separate place instead of in
+the |stack| array. We call the current values |cur_end|, |cur_byte|,
+|cur_name|, |cur_repl|, and |cur_mod|.
+
+The global variable |stack_ptr| tells how many levels of output are
+currently in progress. The end of all output occurs when the stack is
+empty, i.e., when |stack_ptr=0|.

+@* Producing the output.
+The |get_output| routine above handles most of the complexity of output
+generation, but there are two further considerations that have a nontrivial
+effect on \.{TANGLE}'s algorithms.
+
+First, we want to make sure that the output is broken into lines not
+exceeding |line_length| characters per line, where these breaks occur at
+valid places (e.g., not in the middle of a string or a constant or an
+identifier, not between `\.<' and `\.>', not at a `\.{@@\&}' position
+where quantities are being joined together). Therefore we assemble the
+output into a buffer before deciding where the line breaks will appear.
+However, we make very little attempt to make ``logical'' line breaks that
+would enhance the readability of the output; people are supposed to read
+the input of \.{TANGLE} or the \TeX ed output of \.{WEAVE}, but not the
+tangled-up output. The only concession to readability is that a break after
+a semicolon will be made if possible, since commonly used ``pretty
+printing'' routines give better results in such cases.
+
+Second, we want to decimalize non-decimal constants, and to combine integer
+quantities that are added or subtracted, because \PASCAL\ doesn't allow
+constant expressions in subrange types or in case labels. This means we
+want to have a procedure that treats a construction like \.{(E-15+17)}
+as equivalent to `\.{(E+2)}', while also leaving `\.{(1E-15+17)}' and
+`\.{(E-15+17*y)}' untouched. Consider also `\.{-15+17.5}' versus
+`\.{-15+17..5}'. We shall not combine integers preceding or following
+\.*, \./, \.{div}, \.{mod}, or \.{@@\&}. Note that if |y| has been defined
+to equal $-2$, we must expand `\.{x*y}' into `\.{x*(-2)}'; but `\.{x-y}'
+can expand into `\.{x+2}' and we can even change `\.{x - y mod z}' to
+@^mod@>
+`\.{x + 2 mod z}' because \PASCAL\ has a nonstandard \&{mod} operation!
+
+The following solution to these problems has been adopted: An array
+|out_buf| contains characters that have been generated but not yet output,
+and there are three pointers into this array. One of these, |out_ptr|, is
+the number of characters currently in the buffer, and we will have
+|1<=out_ptr<=line_length| most of the time. The second is |break_ptr|,
+which is the largest value |<=out_ptr| such that we are definitely entitled
+to end a line by outputting the characters |out_buf[1..(break_ptr-1)]|;
+we will always have |break_ptr<=line_length|. Finally, |semi_ptr| is either
+zero or the largest known value of a legal break after a semicolon or comment
+on the current line; we will always have |semi_ptr<=break_ptr|.
+
+@<Globals...@>=
+@!out_buf: array [0..out_buf_size] of ASCII_code; {assembled characters}
+@!out_ptr: 0..out_buf_size; {first available place in |out_buf|}
+@!break_ptr: 0..out_buf_size; {last breaking place in |out_buf|}
+@!semi_ptr: 0..out_buf_size; {last semicolon breaking place in |out_buf|}
+
+@ Besides having those three pointers,
+the output process is in one of several states:
+
+\yskip\hang |num_or_id| means that the last item in the buffer is a number or
+identifier, hence a blank space or line break must be inserted if the next
+item is also a number or identifier.
+
+\yskip\hang |unbreakable| means that the last item in the buffer was followed
+by the \.{@@\&} operation that inhibits spaces between it and the next item.
+
+\yskip\hang |sign| means that the last item in the buffer is to be followed
+by \.+ or \.-, depending on whether |out_app| is positive or negative.
+
+\yskip\hang |sign_val| means that the decimal equivalent of
+$\vert|out_val|\vert$ should be appended to the buffer. If |out_val<0|,
+or if |out_val=0| and |last_sign<0|, the number should be preceded by a minus
+sign. Otherwise it should be preceded by the character |out_sign| unless
+|out_sign=0|; the |out_sign| variable is either 0 or \.{"\ "} or \.{"+"}.
+
+\yskip\hang |sign_val_sign| is like |sign_val|, but also append \.+ or \.-
+afterwards, depending on whether |out_app| is positive or negative.
+
+\yskip\hang |sign_val_val| is like |sign_val|, but also append the decimal
+equivalent of |out_app| including its sign, using |last_sign| in case
+|out_app=0|.
+
+\yskip\hang |misc| means none of the above.
+
+\yskip\noindent
+For example, the output buffer and output state run through the following
+sequence as we generate characters from `\.{(x-15+19-2)}':
+$$\vbox{\halign{$\hfil#\hfil$\quad&#\hfil&\quad\hfil#\hfil&\quad
+\hfil#\hfil&\quad\hfil#\hfil&\quad\hfil#\hfil\quad&\hfil#\hfil\cr
+output&|out_buf|&|out_state|&|out_sign|&|out_val|&|out_app|&|last_sign|\cr
+\noalign{\vskip 3pt}
+(&\.(&|misc|\cr
+x&\.{(x}&|num_or_id|\cr
+-&\.{(x}&|sign|&&&$-1$&$-1$\cr
+15&\.{(x}&|sign_val|&\.{"+"}&$-15$&&$-15$\cr

+-&\.{(x}&|sign_val_sign|&\.{"+"}&$+4$&$-1$&$-1$\cr
+2&\.{(x}&|sign_val_val|&\.{"+"}&$+4$&$-2$&$-2$\cr
+)&\.{(x+2)}&|misc|\cr}}$$
+At each stage we have put as much into the buffer as possible without
+knowing what is coming next. Examples like `\.{x-0.1}' indicate why
+|last_sign| is needed to associate the proper sign with an output of zero.
+
+In states |num_or_id|, |unbreakable|, and |misc| the last item in the buffer
+lies between |break_ptr| and |out_ptr-1|, inclusive; in the other states we
+have |break_ptr=out_ptr|.
+
+The numeric values assigned to |num_or_id|, etc., have been chosen to

+the fact that |sign+2=sign_val_sign|.

+as we write it out.
+
+There are three main input routines. The most interesting is the one that gets
+the next token of a \PASCAL\ text; the other two are used to scan rapidly past
+\TeX\ text in the \.{WEB} source code. One of the latter routines will jump to
+the next token that starts with `\.{@@}', and the other skips to the end
+of a \PASCAL\ comment.
+

+The rules for generating the replacement texts corresponding to simple
+macros, parametric macros, and \PASCAL\ texts of a module are almost
+identical, so a single procedure is used for all three cases. The
+differences are that
+
+\yskip\item{a)} The sign |#| denotes a parameter only when it appears
+outside of strings in a parametric macro; otherwise it stands for the
+ASCII character |#|. (This is not used in standard \PASCAL, but some
+\PASCAL s allow, for example, `\.{/\#}' after a certain kind of file name.)
+
+\item{b)}Module names are not allowed in simple macros or parametric macros;
+in fact, the appearance of a module name terminates such macros and denotes
+the name of the current module.
+
+\item{c)}The symbols \.{@@d} and \.{@@f} and \.{@@p} are not allowed after
+module names, while they terminate macro definitions.
+
+@ Therefore there is a procedure |scan_repl| whose parameter |t| specifies
+either |simple| or |parametric| or |module_name|. After |scan_repl| has

+
+@* Debugging.
+The \PASCAL\ debugger with which \.{TANGLE} was developed allows breakpoints
+to be set, and variables can be read and changed, but procedures cannot be
+executed. Therefore a `|debug_help|' procedure has been inserted in the main
+loops of each phase of the program; when |ddt| and |dd| are set to appropriate
+values, symbolic printouts of various tables will appear.
+
+The idea is to set a breakpoint inside the |debug_help| routine, at the
+place of `\ignorespaces|breakpoint:|\unskip' below. Then when
+|debug_help| is to be activated, set |trouble_shooting| equal to |true|.
+The |debug_help| routine will prompt you for values of |ddt| and |dd|,
+discontinuing this when |ddt<=0|; thus you type $2n+1$ integers, ending
+with zero or a negative number. Then control either passes to the
+breakpoint, allowing you to look at and/or change variables (if you typed
+zero), or to exit the routine (if you typed a negative value).
+
+Another global variable, |debug_cycle|, can be used to skip silently
+past calls on |debug_help|. If you set |debug_cycle>1|, the program stops
+only every |debug_cycle| times |debug_help| is called; however,
+any error stop will set |debug_cycle| to zero.
+

+will be consistent with the printed program. More extensive changes,
+which introduce new modules, can be inserted here; then only the index

+@* Index.
+Here is a cross-reference table for the \.{TANGLE} processor.
+All modules in which an identifier is
+used are listed with that identifier, except that reserved words are
+indexed only when they appear in format definitions, and the appearances
+of identifiers in module names are not indexed. Underlined entries
+correspond to where the identifier was declared. Error messages and
+a few other things like ``ASCII code'' are indexed here too.
