+HISTORY for LPeg 0.12
+
+* Changes from version 0.11 to 0.12
+  ---------------------------------
+  + no "unsigned short" limit for pattern sizes
+  + mathtime captures considered nullable
+  + some bugs fixed
+
+* Changes from version 0.10 to 0.11
+  -------------------------------  
+  + complete reimplementation of the code generator
+  + new syntax for table captures
+  + new functions in module 're'
+  + other small improvements
+
+* Changes from version 0.9 to 0.10
+  -------------------------------  
+  + backtrack stack has configurable size
+  + better error messages
+  + Notation for non-terminals in 're' back to A instead o <A>
+  + experimental look-behind pattern
+  + support for external extensions
+  + works with Lua 5.2
+  + consumes less C stack
+
+  - "and" predicates do not keep captures
+
+* Changes from version 0.8 to 0.9
+  -------------------------------  
+  + The accumulator capture was replaced by a fold capture;
+    programs that used the old 'lpeg.Ca' will need small changes.
+  + Some support for character classes from old C locales.
+  + A new named-group capture.
+
+* Changes from version 0.7 to 0.8
+  -------------------------------  
+  + New "match-time" capture.
+  + New "argument capture" that allows passing arguments into the pattern.
+  + Better documentation for 're'.
+  + Several small improvements for 're'.
+  + The 're' module has an incompatibility with previous versions: 
+    now, any use of a non-terminal must be enclosed in angle brackets 
+    (like <B>).
+
+* Changes from version 0.6 to 0.7
+  -------------------------------  
+  + Several improvements in module 're':
+    - better documentation;
+    - support for most captures (all but accumulator);
+    - limited repetitions p{n,m}.
+  + Small improvements in efficiency.
+  + Several small bugs corrected (special thanks to Hans Hagen 
+    and Taco Hoekwater).
+
+* Changes from version 0.5 to 0.6
+  -------------------------------  
+  + Support for non-numeric indices in grammars.
+  + Some bug fixes (thanks to the luatex team).
+  + Some new optimizations; (thanks to Mike Pall).
+  + A new page layout (thanks to Andre Carregal).
+  + Minimal documentation for module 're'.
+
+* Changes from version 0.4 to 0.5
+  -------------------------------  
+  + Several optimizations.
+  + lpeg.P now accepts booleans.
+  + Some new examples.
+  + A proper license.
+  + Several small improvements.
+
+* Changes from version 0.3 to 0.4
+  -------------------------------  
+  + Static check for loops in repetitions and grammars.
+  + Removed label option in captures.
+  + The implementation of captures uses less memory.
+
+* Changes from version 0.2 to 0.3
+  -------------------------------  
+  + User-defined patterns in Lua.
+  + Several new captures.
+
+* Changes from version 0.1 to 0.2
+  -------------------------------  
+  + Several small corrections.
+  + Handles embedded zeros like any other character.
+  + Capture "name" can be any Lua value.
+  + Unlimited number of captures.
+  + Match gets an optional initial position.

+<h2><a name="basic"></a>The <code>re</code> Module</h2>
+
+<p>
+The <code>re</code> module
+(provided by file <code>re.lua</code> in the distribution)
+supports a somewhat conventional regex syntax
+for pattern usage within <a href="lpeg.html">LPeg</a>.
+</p>
+
+<p>
+The next table summarizes <code>re</code>'s syntax.
+A <code>p</code> represents an arbitrary pattern;
+<code>num</code> represents a number (<code>[0-9]+</code>);
+<code>name</code> represents an identifier
+(<code>[a-zA-Z][a-zA-Z0-9_]*</code>).
+Constructions are listed in order of decreasing precedence.
+<table border="1">
+<tbody><tr><td><b>Syntax</b></td><td><b>Description</b></td></tr>
+<tr><td><code>( p )</code></td> <td>grouping</td></tr>
+<tr><td><code>'string'</code></td> <td>literal string</td></tr>

+<p>
+Any space appearing in a syntax description can be
+replaced by zero or more space characters and Lua-style comments
+(<code>--</code> until end of line).
+</p>
+
+<p>
+Character classes define sets of characters.
+An initial <code>^</code> complements the resulting set.
+A range <em>x</em><code>-</code><em>y</em> includes in the set
+all characters with codes between the codes of <em>x</em> and <em>y</em>.
+A pre-defined class <code>%</code><em>name</em> includes all
+characters of that class.
+A simple character includes itself in the set.
+The only special characters inside a class are <code>^</code>
+(special only if it is the first character);
+<code>]</code>
+(can be included in the set as the first character,
+after the optional <code>^</code>);
+<code>%</code> (special only if followed by a letter);
+and <code>-</code>
+(can be included in the set as the first or the last character).
+</p>
+
+<p>
+Currently the pre-defined classes are similar to those from the
+Lua's string library
+(<code>%a</code> for letters,
+<code>%A</code> for non letters, etc.).
+There is also a class <code>%nl</code>
+containing only the newline character,
+which is particularly handy for grammars written inside long strings,
+as long strings do not interpret escape sequences like <code>\n</code>.
+</p>
+
+
+<h2><a name="func">Functions</a></h2>
+
+<h3><code>re.compile (string, [, defs])</code></h3>
+<p>
+Compiles the given string and
+returns an equivalent LPeg pattern.
+The given string may define either an expression or a grammar.
+The optional <code>defs</code> table provides extra Lua values
+to be used by the pattern.
+</p>
+
+<h3><code>re.find (subject, pattern [, init])</code></h3>
+<p>
+Searches the given pattern in the given subject.
+If it finds a match,
+returns the index where this occurrence starts and
+the index where it ends.
+Otherwise, returns nil.
+</p>
+
+<p>
+An optional numeric argument <code>init</code> makes the search
+starts at that position in the subject string.
+As usual in Lua libraries,
+a negative value counts from the end.
+</p>
+
+<h3><code>re.gsub (subject, pattern, replacement)</code></h3>
+<p>
+Does a <em>global substitution</em>,
+replacing all occurrences of <code>pattern</code>
+in the given <code>subject</code> by <code>replacement</code>.
+
+<h3><code>re.match (subject, pattern)</code></h3>
+<p>
+Matches the given pattern against the given subject,
+returning all captures.
+</p>
+
+<h3><code>re.updatelocale ()</code></h3>
+<p>
+Updates the pre-defined character classes to the current locale.
+</p>
+
+
+<h2><a name="ex">Some Examples</a></h2>
+
+<h3>A complete simple program</h3>
+<p>
+The next code shows a simple complete Lua program using
+the <code>re</code> module:
+</p>
+<pre class="example">
+local re = require"re"
+
+-- find the position of the first numeral in a string
+print(re.find("the number 423 is odd", "[0-9]+"))  --&gt; 12    14
+
+-- returns all words in a string
+print(re.match("the number 423 is odd", "({%a+} / .)*"))
+--&gt; the    number    is    odd
+
+-- returns the first numeral in a string
+print(re.match("the number 423 is odd", "s <- {%d+} / . s"))
+--&gt; 423
+
+print(re.gsub("hello World", "[aeiou]", "."))
+--&gt; h.ll. W.rld
+</pre>
+
+
+<h3>Balanced parentheses</h3>
+<p>
+The following call will produce the same pattern produced by the
+Lua expression in the
+<a href="lpeg.html#balanced">balanced parentheses</a> example:
+</p>
+<pre class="example">
+b = re.compile[[  balanced &lt;- "(" ([^()] / balanced)* ")"  ]]
+</pre>
+
+<h3>String reversal</h3>
+<p>
+The next example reverses a string:
+</p>
+<pre class="example">
+rev = re.compile[[ R &lt;- (!.) -&gt; '' / ({.} R) -&gt; '%2%1']]
+print(rev:match"0123456789")   --&gt; 9876543210
+</pre>
+
+<h3>CSV decoder</h3>
+<p>
+The next example replicates the <a href="lpeg.html#CSV">CSV decoder</a>:
+</p>
+<pre class="example">
+record = re.compile[[
+  record &lt;- {| field (',' field)* |} (%nl / !.)
+  field &lt;- escaped / nonescaped
+  nonescaped &lt;- { [^,"%nl]* }
+  escaped &lt;- '"' {~ ([^"] / '""' -&gt; '"')* ~} '"'
+]]
+</pre>
+
+<h3>Lua's long strings</h3>
+<p>
+The next example matches Lua long strings:
+</p>
+<pre class="example">
+c = re.compile([[
+  longstring &lt;- ('[' {:eq: '='* :} '[' close)
+  close &lt;- ']' =eq ']' / . close
+]])
+
+print(c:match'[==[]]===]]]]==]===[]')   --&gt; 17
+</pre>
+
+<h3>Abstract Syntax Trees</h3>
+<p>
+This example shows a simple way to build an
+abstract syntax tree (AST) for a given grammar.
+To keep our example simple,
+let us consider the following grammar
+for lists of names:
+</p>
+<pre class="example">
+p = re.compile[[
+      listname &lt;- (name s)*
+      name &lt;- [a-z][a-z]*
+      s &lt;- %s*
+]]
+</pre>
+<p>
+Now, we will add captures to build a corresponding AST.
+As a first step, the pattern will build a table to
+represent each non terminal;
+terminals will be represented by their corresponding strings:
+</p>
+<pre class="example">
+c = re.compile[[
+      listname &lt;- {| (name s)* |}
+      name &lt;- {| {[a-z][a-z]*} |}
+      s &lt;- %s*
+]]
+</pre>
+<p>
+Now, a match against <code>"hi hello bye"</code>
+results in the table
+<code>{{"hi"}, {"hello"}, {"bye"}}</code>.
+</p>
+<p>
+For such a simple grammar,
+this AST is more than enough;
+actually, the tables around each single name
+are already overkilling.
+More complex grammars,
+however, may need some more structure.
+Specifically,
+it would be useful if each table had
+a <code>tag</code> field telling what non terminal
+that table represents.
+We can add such a tag using
+<a href="lpeg.html/#cap-g">named group captures</a>:
+</p>
+<pre class="example">
+x = re.compile[[
+      listname <- {| {:tag: '' -> 'list':} (name s)* |}
+      name <- {| {:tag: '' -> 'id':} {[a-z][a-z]*} |}
+      s <- ' '*
+]]
+</pre>
+<p>
+With these group captures,
+a match against <code>"hi hello bye"</code>
+results in the following table:
+</p>
+<pre class="example">
+{tag="list",
+  {tag="id", "hi"},
+  {tag="id", "hello"},
+  {tag="id", "bye"}
+}
+</pre>
+
+
+<h3>Indented blocks</h3>
+<p>
+This example breaks indented blocks into tables,
+respecting the indentation:
+</p>
+<pre class="example">
+p = re.compile[[
+  block &lt;- {| {:ident:' '*:} line
+           ((=ident !' ' line) / &(=ident ' ') block)* |}
+  line &lt;- {[^%nl]*} %nl
+]]
+</pre>
+<p>
+As an example,
+consider the following text:
+</p>
+<pre class="example">
+t = p:match[[
+first line
+  subline 1
+  subline 2
+second line
+third line
+  subline 3.1
+    subline 3.1.1
+  subline 3.2
+]]
+</pre>
+<p>
+The resulting table <code>t</code> will be like this:
+</p>
+<pre class="example">
+   {'first line'; {'subline 1'; 'subline 2'; ident = '  '};
+    'second line';
+    'third line'; { 'subline 3.1'; {'subline 3.1.1'; ident = '    '};
+                    'subline 3.2'; ident = '  '};
+    ident = ''}
+</pre>
+
+<h3>Macro expander</h3>
+<p>
+This example implements a simple macro expander.
+Macros must be defined as part of the pattern,
+following some simple rules:
+</p>
+<pre class="example">
+p = re.compile[[
+      text &lt;- {~ item* ~}
+      item &lt;- macro / [^()] / '(' item* ')'
+      arg &lt;- ' '* {~ (!',' item)* ~}
+      args &lt;- '(' arg (',' arg)* ')'
+      -- now we define some macros
+      macro &lt;- ('apply' args) -&gt; '%1(%2)'
+             / ('add' args) -&gt; '%1 + %2'
+             / ('mul' args) -&gt; '%1 * %2'
+]]
+
+print(p:match"add(mul(a,b), apply(f,x))")   --&gt; a * b + f(x)
+</pre>
+<p>
+A <code>text</code> is a sequence of items,
+wherein we apply a substitution capture to expand any macros.
+An <code>item</code> is either a macro,
+any character different from parentheses,
+or a parenthesized expression.
+A macro argument (<code>arg</code>) is a sequence
+of items different from a comma.
+(Note that a comma may appear inside an item,
+e.g., inside a parenthesized expression.)
+Again we do a substitution capture to expand any macro
+in the argument before expanding the outer macro.
+<code>args</code> is a list of arguments separated by commas.
+Finally we define the macros.
+Each macro is a string substitution;
+it replaces the macro name and its arguments by its corresponding string,
+with each <code>%</code><em>n</em> replaced by the <em>n</em>-th argument.
+</p>
+
+<h3>Patterns</h3>
+<p>
+This example shows the complete syntax
+of patterns accepted by <code>re</code>.
+</p>
+<pre class="example">
+p = [=[
+
+pattern         &lt;- exp !.
+exp             &lt;- S (alternative / grammar)
+
+alternative     &lt;- seq ('/' S seq)*
+seq             &lt;- prefix*
+prefix          &lt;- '&amp;' S prefix / '!' S prefix / suffix
+suffix          &lt;- primary S (([+*?]
+                            / '^' [+-]? num
+                            / '-&gt;' S (string / '{}' / name)

-Mark Pulford <mark@kyne.com.au>
-:revdate: 1st March 2012
-
-Overview
---------
-
-The Lua CJSON module provides JSON support for Lua.
-
-*Features*::
-- Fast, standards compliant encoding/parsing routines
-- Full support for JSON with UTF-8, including decoding surrogate pairs
-- Optional run-time support for common exceptions to the JSON
-  specification (infinity, NaN,..)
-- No dependencies on other libraries
-
-*Caveats*::
-- UTF-16 and UTF-32 are not supported
-
-Lua CJSON is covered by the MIT license. Review the file +LICENSE+ for
-details.
-
-The latest version of this software is available from the
-http://www.kyne.com.au/%7Emark/software/lua-cjson.php[Lua CJSON website].
-
-Feel free to email me if you have any patches, suggestions, or comments.
-
-
-Installation
-------------
-
-Lua CJSON requires either http://www.lua.org[Lua] 5.1, Lua 5.2, or
-http://www.luajit.org[LuaJIT] to build.
-
-The build method can be selected from 4 options:
-
-Make:: Unix (including Linux, BSD, Mac OSX & Solaris), Windows
-CMake:: Unix, Windows
-RPM:: Linux
-LuaRocks:: Unix, Windows
-
-
-Make
-~~~~
-
-The included +Makefile+ has generic settings.
-
-First, review and update the included makefile to suit your platform (if
-required).
-
-Next, build and install the module:
-
-[source,sh]
-make install
-
-Or install manually into your Lua module directory:
-
-[source,sh]
-make
-cp cjson.so $LUA_MODULE_DIRECTORY
-
-
-CMake
-~~~~~
-
-http://www.cmake.org[CMake] can generate build configuration for many
-different platforms (including Unix and Windows).
-
-First, generate the makefile for your platform using CMake. If CMake is
-unable to find Lua, manually set the +LUA_DIR+ environment variable to
-the base prefix of your Lua 5.1 installation.
-
-While +cmake+ is used in the example below, +ccmake+ or +cmake-gui+ may
-be used to present an interface for changing the default build options.
-
-[source,sh]
-mkdir build
-cd build
-# Optional: export LUA_DIR=$LUA51_PREFIX
-cmake ..
-
-Next, build and install the module:
-
-[source,sh]
-make install
-# Or:
-make
-cp cjson.so $LUA_MODULE_DIRECTORY
-
-Review the
-http://www.cmake.org/cmake/help/documentation.html[CMake documentation]
-for further details.
-
-
-RPM
-~~~
-
-Linux distributions using http://rpm.org[RPM] can create a package via
-the included RPM spec file. Ensure the +rpm-build+ package (or similar)
-has been installed.
-
-Build and install the module via RPM:
-
-[source,sh]
-rpmbuild -tb lua-cjson-2.1.0.tar.gz
-rpm -Uvh $LUA_CJSON_RPM
-
-
-LuaRocks
-~~~~~~~~
-
-http://luarocks.org[LuaRocks] can be used to install and manage Lua
-modules on a wide range of platforms (including Windows).
-
-First, extract the Lua CJSON source package.
-
-Next, install the module:
-
-[source,sh]
-cd lua-cjson-2.1.0
-luarocks make
-
-[NOTE]
-LuaRocks does not support platform specific configuration for Solaris.
-On Solaris, you may need to manually uncomment +USE_INTERNAL_ISINF+ in
-the rockspec before building this module.
-
-Review the http://luarocks.org/en/Documentation[LuaRocks documentation]
-for further details.
-
-
-[[build_options]]
-Build Options (#define)
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Lua CJSON offers several +#define+ build options to address portability
-issues, and enable non-default features. Some build methods may
-automatically set platform specific options if required. Other features
-should be enabled manually.
-
-USE_INTERNAL_ISINF:: Workaround for Solaris platforms missing +isinf+.
-DISABLE_INVALID_NUMBERS:: Recommended on platforms where +strtod+ /
-  +sprintf+ are not POSIX compliant (eg, Windows MinGW). Prevents
-  +cjson.encode_invalid_numbers+ and +cjson.decode_invalid_numbers+ from
-  being enabled. However, +cjson.encode_invalid_numbers+ may still be
-  set to +"null"+. When using the Lua CJSON built-in floating point
-  conversion this option is unnecessary and is ignored.
-
-
-Built-in floating point conversion
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Lua CJSON may be built with David Gay's
-http://www.netlib.org/fp/[floating point conversion routines]. This can
-increase overall performance by up to 50% on some platforms when
-converting a large amount of numeric data. However, this option reduces
-portability and is disabled by default.
-
-USE_INTERNAL_FPCONV:: Enable internal number conversion routines.
-IEEE_BIG_ENDIAN:: Must be set on big endian architectures.
-MULTIPLE_THREADS:: Must be set if Lua CJSON may be used in a
-  multi-threaded application. Requires the _pthreads_ library.
-

-Synopsis
-~~~~~~~~
-
-[source,lua]
-------------
--- Module instantiation
-local cjson = require "cjson"
-local cjson2 = cjson.new()
-local cjson_safe = require "cjson.safe"
-
--- Translate Lua value to/from JSON
-text = cjson.encode(value)
-value = cjson.decode(text)
-
--- Get and/or set Lua CJSON configuration
-setting = cjson.decode_invalid_numbers([setting])
-setting = cjson.encode_invalid_numbers([setting])
-keep = cjson.encode_keep_buffer([keep])
-depth = cjson.encode_max_depth([depth])
-depth = cjson.decode_max_depth([depth])
-convert, ratio, safe = cjson.encode_sparse_array([convert[, ratio[, safe]]])
-------------
-
-
-Module Instantiation
-~~~~~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-local cjson = require "cjson"
-local cjson2 = cjson.new()
-local cjson_safe = require "cjson.safe"
-------------
-
-Import Lua CJSON via the Lua +require+ function. Lua CJSON does not
-register a global module table.
-
-The +cjson+ module will throw an error during JSON conversion if any
-invalid data is encountered. Refer to <<cjson_encode,+cjson.encode+>>
-and <<cjson_decode,+cjson.decode+>> for details.
-
-The +cjson.safe+ module behaves identically to the +cjson+ module,
-except when errors are encountered during JSON conversion. On error, the
-+cjson_safe.encode+ and +cjson_safe.decode+ functions will return
-+nil+ followed by the error message.
-
-+cjson.new+ can be used to instantiate an independent copy of the Lua
-CJSON module. The new module has a separate persistent encoding buffer,
-and default settings.
-
-Lua CJSON can support Lua implementations using multiple preemptive
-threads within a single Lua state provided the persistent encoding
-buffer is not shared. This can be achieved by one of the following
-methods:
-
-- Disabling the persistent encoding buffer with
-  <<encode_keep_buffer,+cjson.encode_keep_buffer+>>
-- Ensuring each thread calls <<encode,+cjson.encode+>> separately (ie,
-  treat +cjson.encode+ as non-reentrant).
-- Using a separate +cjson+ module table per preemptive thread
-  (+cjson.new+)
-
-[NOTE]
-Lua CJSON uses +strtod+ and +snprintf+ to perform numeric conversion as
-they are usually well supported, fast and bug free. However, these
-functions require a workaround for JSON encoding/parsing under locales
-using a comma decimal separator. Lua CJSON detects the current locale
-during instantiation to determine and automatically implement the
-workaround if required. Lua CJSON should be reinitialised via
-+cjson.new+ if the locale of the current process changes. Using a
-different locale per thread is not supported.
-
-
-decode
-~~~~~~
-
-[source,lua]
-------------
-value = cjson.decode(json_text)
-------------
-
-+cjson.decode+ will deserialise any UTF-8 JSON string into a Lua value
-or table.
-
-UTF-16 and UTF-32 JSON strings are not supported.
-
-+cjson.decode+ requires that any NULL (ASCII 0) and double quote (ASCII
-34) characters are escaped within strings. All escape codes will be
-decoded and other bytes will be passed transparently. UTF-8 characters
-are not validated during decoding and should be checked elsewhere if
-required.
-
-JSON +null+ will be converted to a NULL +lightuserdata+ value. This can
-be compared with +cjson.null+ for convenience.
-
-By default, numbers incompatible with the JSON specification (infinity,
-NaN, hexadecimal) can be decoded. This default can be changed with
-<<decode_invalid_numbers,+cjson.decode_invalid_numbers+>>.
-
-.Example: Decoding
-[source,lua]
-json_text = '[ true, { "foo": "bar" } ]'
-value = cjson.decode(json_text)
--- Returns: { true, { foo = "bar" } }
-
-[CAUTION]
-Care must be taken after decoding JSON objects with numeric keys. Each
-numeric key will be stored as a Lua +string+. Any subsequent code
-assuming type +number+ may break.
-
-
-[[decode_invalid_numbers]]
-decode_invalid_numbers
-~~~~~~~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-setting = cjson.decode_invalid_numbers([setting])
--- "setting" must be a boolean. Default: true.
-------------
-
-Lua CJSON may generate an error when trying to decode numbers not
-supported by the JSON specification. _Invalid numbers_ are defined as:
-
-- infinity
-- not-a-number (NaN)
-- hexadecimal
-
-Available settings:
-
-+true+:: Accept and decode _invalid numbers_. This is the default
-  setting.
-+false+:: Throw an error when _invalid numbers_ are encountered.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-
-[[decode_max_depth]]
-decode_max_depth
-~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-depth = cjson.decode_max_depth([depth])
--- "depth" must be a positive integer. Default: 1000.
-------------
-
-Lua CJSON will generate an error when parsing deeply nested JSON once
-the maximum array/object depth has been exceeded. This check prevents
-unnecessarily complicated JSON from slowing down the application, or
-crashing the application due to lack of process stack space.
-
-An error may be generated before the depth limit is hit if Lua is unable
-to allocate more objects on the Lua stack.
-
-By default, Lua CJSON will reject JSON with arrays and/or objects nested
-more than 1000 levels deep.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-
-[[encode]]
-encode
-~~~~~~
-
-[source,lua]
-------------
-json_text = cjson.encode(value)
-------------
-
-+cjson.encode+ will serialise a Lua value into a string containing the
-JSON representation.
-
-+cjson.encode+ supports the following types:
-
-- +boolean+
-- +lightuserdata+ (NULL value only)
-- +nil+
-- +number+
-- +string+
-- +table+
-
-The remaining Lua types will generate an error:
-
-- +function+
-- +lightuserdata+ (non-NULL values)
-- +thread+
-- +userdata+
-
-By default, numbers are encoded with 14 significant digits. Refer to
-<<encode_number_precision,+cjson.encode_number_precision+>> for details.
-
-Lua CJSON will escape the following characters within each UTF-8 string:
-
-- Control characters (ASCII 0 - 31)
-- Double quote (ASCII 34)
-- Forward slash (ASCII 47)
-- Blackslash (ASCII 92)
-- Delete (ASCII 127)
-
-All other bytes are passed transparently.
-
-[CAUTION]
-=========
-Lua CJSON will successfully encode/decode binary strings, but this is
-technically not supported by JSON and may not be compatible with other
-JSON libraries. To ensure the output is valid JSON, applications should
-ensure all Lua strings passed to +cjson.encode+ are UTF-8.
-
-Base64 is commonly used to encode binary data as the most efficient
-encoding under UTF-8 can only reduce the encoded size by a further
-&#126;8%. Lua Base64 routines can be found in the
-http://w3.impa.br/%7Ediego/software/luasocket/[LuaSocket] and
-http://www.tecgraf.puc-rio.br/%7Elhf/ftp/lua/#lbase64[lbase64] packages.
-=========
-
-Lua CJSON uses a heuristic to determine whether to encode a Lua table as
-a JSON array or an object. A Lua table with only positive integer keys
-of type +number+ will be encoded as a JSON array. All other tables will
-be encoded as a JSON object.
-
-Lua CJSON does not use metamethods when serialising tables.
-
-- +rawget+ is used to iterate over Lua arrays
-- +next+ is used to iterate over Lua objects
-
-Lua arrays with missing entries (_sparse arrays_) may optionally be
-encoded in several different ways. Refer to
-<<encode_sparse_array,+cjson.encode_sparse_array+>> for details.
-
-JSON object keys are always strings. Hence +cjson.encode+ only supports
-table keys which are type +number+ or +string+. All other types will
-generate an error.
-
-[NOTE]
-Standards compliant JSON must be encapsulated in either an object (+{}+)
-or an array (+[]+). If strictly standards compliant JSON is desired, a
-table must be passed to +cjson.encode+.
-
-By default, encoding the following Lua values will generate errors:
-
-- Numbers incompatible with the JSON specification (infinity, NaN)
-- Tables nested more than 1000 levels deep
-- Excessively sparse Lua arrays
-
-These defaults can be changed with:
-
-- <<encode_invalid_numbers,+cjson.encode_invalid_numbers+>>
-- <<encode_max_depth,+cjson.encode_max_depth+>>
-- <<encode_sparse_array,+cjson.encode_sparse_array+>>
-
-.Example: Encoding
-[source,lua]
-value = { true, { foo = "bar" } }
-json_text = cjson.encode(value)
--- Returns: '[true,{"foo":"bar"}]'
-
-
-[[encode_invalid_numbers]]
-encode_invalid_numbers
-~~~~~~~~~~~~~~~~~~~~~~
-[source,lua]
-------------
-setting = cjson.encode_invalid_numbers([setting])
--- "setting" must a boolean or "null". Default: false.
-------------
-
-Lua CJSON may generate an error when encoding floating point numbers not
-supported by the JSON specification (_invalid numbers_):
-
-- infinity
-- not-a-number (NaN)
-
-Available settings:
-
-+true+:: Allow _invalid numbers_ to be encoded. This will generate
-  non-standard JSON, but this output is supported by some libraries.
-+"null"+:: Encode _invalid numbers_ as a JSON +null+ value. This allows
-  infinity and NaN to be encoded into valid JSON.
-+false+:: Throw an error when attempting to encode _invalid numbers_.
-  This is the default setting.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-
-[[encode_keep_buffer]]
-encode_keep_buffer
-~~~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-keep = cjson.encode_keep_buffer([keep])
--- "keep" must be a boolean. Default: true.
-------------
-
-Lua CJSON can reuse the JSON encoding buffer to improve performance.
-
-Available settings:
-
-+true+:: The buffer will grow to the largest size required and is not
-  freed until the Lua CJSON module is garbage collected. This is the
-  default setting.
-+false+:: Free the encode buffer after each call to +cjson.encode+.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-
-[[encode_max_depth]]
-encode_max_depth
-~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-depth = cjson.encode_max_depth([depth])
--- "depth" must be a positive integer. Default: 1000.
-------------
-
-Once the maximum table depth has been exceeded Lua CJSON will generate
-an error. This prevents a deeply nested or recursive data structure from
-crashing the application.
-
-By default, Lua CJSON will generate an error when trying to encode data
-structures with more than 1000 nested tables.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-.Example: Recursive Lua table
-[source,lua]
-a = {}; a[1] = a
-
-
-[[encode_number_precision]]
-encode_number_precision
-~~~~~~~~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-precision = cjson.encode_number_precision([precision])
--- "precision" must be an integer between 1 and 14. Default: 14.
-------------
-
-The amount of significant digits returned by Lua CJSON when encoding
-numbers can be changed to balance accuracy versus performance. For data
-structures containing many numbers, setting
-+cjson.encode_number_precision+ to a smaller integer, for example +3+,
-can improve encoding performance by up to 50%.
-
-By default, Lua CJSON will output 14 significant digits when converting
-a number to text.
-
-The current setting is always returned, and is only updated when an
-argument is provided.
-
-
-[[encode_sparse_array]]
-encode_sparse_array
-~~~~~~~~~~~~~~~~~~~
-
-[source,lua]
-------------
-convert, ratio, safe = cjson.encode_sparse_array([convert[, ratio[, safe]]])
--- "convert" must be a boolean. Default: false.
--- "ratio" must be a positive integer. Default: 2.
--- "safe" must be a positive integer. Default: 10.
-------------
-
-Lua CJSON classifies a Lua table into one of three kinds when encoding a
-JSON array. This is determined by the number of values missing from the
-Lua array as follows:
-
-Normal:: All values are available.
-Sparse:: At least 1 value is missing.
-Excessively sparse:: The number of values missing exceeds the configured
-  ratio.
-
-Lua CJSON encodes sparse Lua arrays as JSON arrays using JSON +null+ for
-the missing entries.
-
-An array is excessively sparse when all the following conditions are
-met:
-
-- +ratio+ > +0+
-- _maximum_index_ > +safe+
-- _maximum_index_ > _item_count_ * +ratio+
-
-Lua CJSON will never consider an array to be _excessively sparse_ when
-+ratio+ = +0+. The +safe+ limit ensures that small Lua arrays are always
-encoded as sparse arrays.
-
-By default, attempting to encode an _excessively sparse_ array will
-generate an error. If +convert+ is set to +true+, _excessively sparse_
-arrays will be converted to a JSON object.
-
-The current settings are always returned. A particular setting is only
-changed when the argument is provided (non-++nil++).
-
-.Example: Encoding a sparse array
-[source,lua]
-cjson.encode({ [3] = "data" })
--- Returns: '[null,null,"data"]'
-
-.Example: Enabling conversion to a JSON object
-[source,lua]
-cjson.encode_sparse_array(true)
-cjson.encode({ [1000] = "excessively sparse" })
--- Returns: '{"1000":"excessively sparse"}'
-
-
-API (Variables)
----------------
-
-_NAME
-~~~~~
-
-The name of the Lua CJSON module (+"cjson"+).
-
-
-_VERSION
-~~~~~~~~
-
-The version number of the Lua CJSON module (+"2.1.0"+).
-
-
-null
-~~~~
-
-Lua CJSON decodes JSON +null+ as a Lua +lightuserdata+ NULL pointer.
-+cjson.null+ is provided for comparison.

-JSON module performance comparison under Lua
-============================================
-Mark Pulford <mark@kyne.com.au>
-:revdate: January 22, 2012
-
-This performance comparison aims to provide a guide of relative
-performance between several fast and popular JSON modules.
-
-The examples used in this comparison were mostly sourced from the
-http://json.org[JSON website] and
-http://tools.ietf.org/html/rfc4627[RFC 4627].
-
-Performance will vary widely between platforms and data sets. These
-results should only be used as an approximation.
-
-
-Modules
--------
-
-The following JSON modules for Lua were tested:
-
-http://chiselapp.com/user/dhkolf/repository/dkjson/[DKJSON 2.1]::
-  - Lua implementation with no dependencies on other libraries
-  - Supports LPeg to improve decode performance
-
-https://github.com/brimworks/lua-yajl[Lua YAJL 2.0]::
-  - C wrapper for the YAJL library
-
-http://www.kyne.com.au/%7Emark/software/lua-cjson.php[Lua CSJON 2.0.0]::
-  - C implementation with no dependencies on other libraries
-
-
-Summary
--------
-
-All modules were built and tested as follows:
-
-DKJSON:: Tested with/without LPeg 10.2.
-Lua YAJL:: Tested with YAJL 2.0.4.
-Lua CJSON:: Tested with Libc and internal floating point conversion
-  routines.
-
-The following Lua implementations were used for this comparison:
-
-- http://www.lua.org[Lua 5.1.4] (_Lua_)
-- http://www.luajit.org[LuaJIT 2.0.0-beta9] (_JIT_)
-
-These results show the number of JSON operations per second sustained by
-each module. All results have been normalised against the pure Lua
-DKJSON implementation.

-Abstract
-
-   JavaScript Object Notation (JSON) is a lightweight, text-based,
-   language-independent data interchange format.  It was derived from
-   the ECMAScript Programming Language Standard.  JSON defines a small
-   set of formatting rules for the portable representation of structured
-   data.
-
-1.  Introduction
-
-   JavaScript Object Notation (JSON) is a text format for the
-   serialization of structured data.  It is derived from the object
-   literals of JavaScript, as defined in the ECMAScript Programming
-   Language Standard, Third Edition [ECMA].
-
-   JSON can represent four primitive types (strings, numbers, booleans,
-   and null) and two structured types (objects and arrays).
-
-   A string is a sequence of zero or more Unicode characters [UNICODE].
-
-   An object is an unordered collection of zero or more name/value
-   pairs, where a name is a string and a value is a string, number,
-   boolean, null, object, or array.
-
-   An array is an ordered sequence of zero or more values.
-
-   The terms "object" and "array" come from the conventions of
-   JavaScript.
-
-   JSON's design goals were for it to be minimal, portable, textual, and
-   a subset of JavaScript.

-1.1.  Conventions Used in This Document
-
-   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
-   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
-   document are to be interpreted as described in [RFC2119].
-
-   The grammatical rules in this document are to be interpreted as
-   described in [RFC4234].
-
-2.  JSON Grammar
-
-   A JSON text is a sequence of tokens.  The set of tokens includes six
-   structural characters, strings, numbers, and three literal names.
-
-   A JSON text is a serialized object or array.
-
-      JSON-text = object / array
-
-   These are the six structural characters:
-
-      begin-array     = ws %x5B ws  ; [ left square bracket
-
-      begin-object    = ws %x7B ws  ; { left curly bracket
-
-      end-array       = ws %x5D ws  ; ] right square bracket
-
-      end-object      = ws %x7D ws  ; } right curly bracket
-
-      name-separator  = ws %x3A ws  ; : colon
-
-      value-separator = ws %x2C ws  ; , comma
-
-   Insignificant whitespace is allowed before or after any of the six
-   structural characters.
-
-      ws = *(
-                %x20 /              ; Space
-                %x09 /              ; Horizontal tab
-                %x0A /              ; Line feed or New line
-                %x0D                ; Carriage return
-            )
-
-2.1.  Values
-
-   A JSON value MUST be an object, array, number, or string, or one of
-   the following three literal names:
-
-      false null true
-
-
-
-Crockford                    Informational                      [Page 2]

-RFC 4627                          JSON                         July 2006
-
-
-   The literal names MUST be lowercase.  No other literal names are
-   allowed.
-
-         value = false / null / true / object / array / number / string
-
-         false = %x66.61.6c.73.65   ; false
-
-         null  = %x6e.75.6c.6c      ; null
-
-         true  = %x74.72.75.65      ; true
-
-2.2.  Objects
-
-   An object structure is represented as a pair of curly brackets
-   surrounding zero or more name/value pairs (or members).  A name is a
-   string.  A single colon comes after each name, separating the name
-   from the value.  A single comma separates a value from a following
-   name.  The names within an object SHOULD be unique.
-
-      object = begin-object [ member *( value-separator member ) ]
-      end-object
-
-      member = string name-separator value
-
-2.3.  Arrays
-
-   An array structure is represented as square brackets surrounding zero
-   or more values (or elements).  Elements are separated by commas.
-
-      array = begin-array [ value *( value-separator value ) ] end-array
-
-2.4.  Numbers
-
-   The representation of numbers is similar to that used in most
-   programming languages.  A number contains an integer component that
-   may be prefixed with an optional minus sign, which may be followed by
-   a fraction part and/or an exponent part.
-
-   Octal and hex forms are not allowed.  Leading zeros are not allowed.
-
-   A fraction part is a decimal point followed by one or more digits.
-
-   An exponent part begins with the letter E in upper or lowercase,
-   which may be followed by a plus or minus sign.  The E and optional
-   sign are followed by one or more digits.
-
-   Numeric values that cannot be represented as sequences of digits
-   (such as Infinity and NaN) are not permitted.

-
-
-         number = [ minus ] int [ frac ] [ exp ]
-
-         decimal-point = %x2E       ; .
-
-         digit1-9 = %x31-39         ; 1-9

-
-         minus = %x2D               ; -
-

-
-         zero = %x30                ; 0
-
-2.5.  Strings
-
-   The representation of strings is similar to conventions used in the C
-   family of programming languages.  A string begins and ends with
-   quotation marks.  All Unicode characters may be placed within the
-   quotation marks except for the characters that must be escaped:
-   quotation mark, reverse solidus, and the control characters (U+0000
-   through U+001F).
-
-   Any character may be escaped.  If the character is in the Basic
-   Multilingual Plane (U+0000 through U+FFFF), then it may be
-   represented as a six-character sequence: a reverse solidus, followed
-   by the lowercase letter u, followed by four hexadecimal digits that
-   encode the character's code point.  The hexadecimal letters A though
-   F can be upper or lowercase.  So, for example, a string containing
-   only a single reverse solidus character may be represented as
-   "\u005C".
-
-   Alternatively, there are two-character sequence escape
-   representations of some popular characters.  So, for example, a
-   string containing only a single reverse solidus character may be
-   represented more compactly as "\\".
-
-   To escape an extended character that is not in the Basic Multilingual
-   Plane, the character is represented as a twelve-character sequence,
-   encoding the UTF-16 surrogate pair.  So, for example, a string
-   containing only the G clef character (U+1D11E) may be represented as
-   "\uD834\uDD1E".

-
-         unescaped = %x20-21 / %x23-5B / %x5D-10FFFF
-
-3.  Encoding
-
-   JSON text SHALL be encoded in Unicode.  The default encoding is
-   UTF-8.
-
-   Since the first two characters of a JSON text will always be ASCII
-   characters [RFC0020], it is possible to determine whether an octet
-   stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking
-   at the pattern of nulls in the first four octets.
-
-           00 00 00 xx  UTF-32BE
-           00 xx 00 xx  UTF-16BE
-           xx 00 00 00  UTF-32LE
-           xx 00 xx 00  UTF-16LE
-           xx xx xx xx  UTF-8
-
-4.  Parsers
-
-   A JSON parser transforms a JSON text into another representation.  A
-   JSON parser MUST accept all texts that conform to the JSON grammar.
-   A JSON parser MAY accept non-JSON forms or extensions.
-
-   An implementation may set limits on the size of texts that it
-   accepts.  An implementation may set limits on the maximum depth of
-   nesting.  An implementation may set limits on the range of numbers.
-   An implementation may set limits on the length and character contents
-   of strings.

-
-
-5. Generators
-
-   A JSON generator produces JSON text.  The resulting text MUST
-   strictly conform to the JSON grammar.
-
-6. IANA Considerations
-
-   The MIME media type for JSON text is application/json.
-
-   Type name: application
-
-   Subtype name: json
-
-   Required parameters: n/a
-
-   Optional parameters: n/a
-
-   Encoding considerations: 8bit if UTF-8; binary if UTF-16 or UTF-32
-
-      JSON may be represented using UTF-8, UTF-16, or UTF-32.  When JSON
-      is written in UTF-8, JSON is 8bit compatible.  When JSON is
-      written in UTF-16 or UTF-32, the binary content-transfer-encoding
-      must be used.
-
-   Security considerations:
-
-   Generally there are security issues with scripting languages.  JSON
-   is a subset of JavaScript, but it is a safe subset that excludes
-   assignment and invocation.
-
-   A JSON text can be safely passed into JavaScript's eval() function
-   (which compiles and executes a string) if all the characters not
-   enclosed in strings are in the set of characters that form JSON
-   tokens.  This can be quickly determined in JavaScript with two
-   regular expressions and calls to the test and replace methods.
-
-      var my_JSON_object = !(/[^,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]/.test(
-             text.replace(/"(\\.|[^"\\])*"/g, ''))) &&
-         eval('(' + text + ')');
-
-   Interoperability considerations: n/a
-
-   Published specification: RFC 4627

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public	Domain
+
+-----------------
+Modified 7/98
+By James H.	Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a	problem	which generated	improper hash values on	16 bit machines
+Routine	SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned	char* data,	unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned	char* data,	unsigned
+long len)
+
+The	'len' parameter	was	declared an	int	which works	fine on	32 bit machines.
+However, on	16 bit machines	an int is too small	for	the	shifts being done
+against
+it.	 This caused the hash function to generate incorrect values	if len was
+greater	than 8191 (8K -	1) due to the 'len << 3' on	line 3 of SHA1Update().
+
+Since the file IO in main()	reads 16K at a time, any file 8K or	larger would
+be guaranteed to generate the wrong	hash (e.g. Test	Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables	i &	j in SHA1Update	to
+unsigned long from unsigned	int	for	the	same reason.
+
+These changes should make no difference	to any 32 bit implementations since
+an
+int	and	a long are the same	size in	those environments.
+
+--
+I also corrected a few compiler	warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0)	at end of main.
+
+ALL	changes	I made can be located by searching for comments	containing 'JHB'
