+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+                   RECURSION IN THE match() FUNCTION
+
+The match() function is highly recursive, though not every recursive call
+increases the recursive depth. Nevertheless, some regular expressions can cause
+it to recurse to a great depth. I was writing for Unix, so I just let it call
+itself recursively. This uses the stack for saving everything that has to be
+saved for a recursive call. On Unix, the stack can be large, and this works
+fine.
+
+It turns out that on some non-Unix-like systems there are problems with
+programs that use a lot of stack. (This despite the fact that every last chip
+has oodles of memory these days, and techniques for extending the stack have
+been known for decades.) So....
+
+There is a fudge, triggered by defining NO_RECURSE, which avoids recursive
+calls by keeping local variables that need to be preserved in blocks of memory
+obtained from malloc() instead instead of on the stack. Macros are used to
+achieve this so that the actual code doesn't look very different to what it
+always used to.
+
+The original heap-recursive code used longjmp(). However, it seems that this
+can be very slow on some operating systems. Following a suggestion from Stan
+Switzer, the use of longjmp() has been abolished, at the cost of having to
+provide a unique number for each call to RMATCH. There is no way of generating
+a sequence of numbers at compile time in C. I have given them names, to make
+them stand out more clearly.
+
+Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
+FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
+tests. Furthermore, not using longjmp() means that local dynamic variables
+don't have indeterminate values; this has meant that the frame size can be
+reduced because the result can be "passed back" by straight setting of the
+variable instead of being passed in the frame.

+/* This function is called recursively in many circumstances. Whenever it
+returns a negative (error) response, the outer incarnation must also return the

+
+Performance note: It might be tempting to extract commonly used fields from the
+md structure (e.g. utf8, end_subject) into individual variables to improve
+performance. Tests using gcc on a SPARC disproved this; in the first case, it
+made performance worse.
+
+Arguments:
+   eptr        pointer to current character in subject
+   ecode       pointer to current position in compiled code
+   mstart      pointer to the current match start position (can be modified
+                 by encountering \K)
+   offset_top  current top pointer
+   md          pointer to "static" info for the match
+   ims         current /i, /m, and /s options
+   eptrb       pointer to chain of blocks containing eptr at start of
+                 brackets - for testing for empty matches
+   flags       can contain
+                 match_condassert - this is an assertion condition
+                 match_cbegroup - this is the start of an unlimited repeat
+                   group that can match an empty string
+   rdepth      the recursion depth
+
+Returns:       MATCH_MATCH if matched            )  these values are >= 0
+               MATCH_NOMATCH if failed to match  )
+               a negative PCRE_ERROR_xxx value if aborted by an error condition

+/* When compiling a DLL for Windows, the exported symbols have to be declared
+using some MS magic. I found some useful information on this web page:
+http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
+information there, using __declspec(dllexport) without "extern" we have a
+definition; with "extern" we have a declaration. The settings here override the
+setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
+which is all that is needed for applications (they just import the symbols). We
+use:
+
+  PCRE_EXP_DECL       for declarations
+  PCRE_EXP_DEFN       for definitions of exported functions
+  PCRE_EXP_DATA_DEFN  for definitions of exported variables
+
+The reason for the two DEFN macros is that in non-Windows environments, one
+does not want to have "extern" before variable definitions because it leads to
+compiler warnings. So we distinguish between functions and variables. In
+Windows, the two should always be the same.
+
+The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
+which is an application, but needs to import this file in order to "peek" at
+internals, can #include pcre.h first to get an application's-eye view.
+
+In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
+special-purpose environments) might want to stick other stuff in front of
+exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
+PCRE_EXP_DATA_DEFN only if they are not already set. */

+#define _PCRECPP_H
+
+// C++ interface to the pcre regular-expression library.  RE supports
+// Perl-style regular expressions (with extensions like \d, \w, \s,
+// ...).
+//
+// -----------------------------------------------------------------------
+// REGEXP SYNTAX:
+//
+// This module is part of the pcre library and hence supports its syntax
+// for regular expressions.
+//
+// The syntax is pretty similar to Perl's.  For those not familiar
+// with Perl's regular expressions, here are some examples of the most
+// commonly used extensions:
+//
+//   "hello (\\w+) world"  -- \w matches a "word" character
+//   "version (\\d+)"      -- \d matches a digit
+//   "hello\\s+world"      -- \s matches any whitespace character
+//   "\\b(\\w+)\\b"        -- \b matches empty string at a word boundary
+//   "(?i)hello"           -- (?i) turns on case-insensitive matching
+//   "/\\*(.*?)\\*/"       -- .*? matches . minimum no. of times possible
+//
+// -----------------------------------------------------------------------
+// MATCHING INTERFACE:
+//
+// The "FullMatch" operation checks that supplied text matches a
+// supplied pattern exactly.
+//
+// Example: successful match
+//    pcrecpp::RE re("h.*o");
+//    re.FullMatch("hello");
+//
+// Example: unsuccessful match (requires full match):
+//    pcrecpp::RE re("e");
+//    !re.FullMatch("hello");
+//
+// Example: creating a temporary RE object:
+//    pcrecpp::RE("h.*o").FullMatch("hello");
+//
+// You can pass in a "const char*" or a "string" for "text".  The
+// examples below tend to use a const char*.
+//
+// You can, as in the different examples above, store the RE object
+// explicitly in a variable or use a temporary RE object.  The
+// examples below use one mode or the other arbitrarily.  Either
+// could correctly be used for any of these examples.
+//
+// -----------------------------------------------------------------------
+// MATCHING WITH SUB-STRING EXTRACTION:
+//
+// You can supply extra pointer arguments to extract matched subpieces.
+//
+// Example: extracts "ruby" into "s" and 1234 into "i"
+//    int i;
+//    string s;
+//    pcrecpp::RE re("(\\w+):(\\d+)");
+//    re.FullMatch("ruby:1234", &s, &i);
+//
+// Example: does not try to extract any extra sub-patterns
+//    re.FullMatch("ruby:1234", &s);
+//
+// Example: does not try to extract into NULL
+//    re.FullMatch("ruby:1234", NULL, &i);
+//
+// Example: integer overflow causes failure
+//    !re.FullMatch("ruby:1234567891234", NULL, &i);
+//
+// Example: fails because there aren't enough sub-patterns:
+//    !pcrecpp::RE("\\w+:\\d+").FullMatch("ruby:1234", &s);
+//
+// Example: fails because string cannot be stored in integer
+//    !pcrecpp::RE("(.*)").FullMatch("ruby", &i);
+//
+// The provided pointer arguments can be pointers to any scalar numeric
+// type, or one of
+//    string        (matched piece is copied to string)
+//    StringPiece   (StringPiece is mutated to point to matched piece)
+//    T             (where "bool T::ParseFrom(const char*, int)" exists)
+//    NULL          (the corresponding matched sub-pattern is not copied)
+//
+// CAVEAT: An optional sub-pattern that does not exist in the matched
+// string is assigned the empty string.  Therefore, the following will
+// return false (because the empty string is not a valid number):
+//    int number;
+//    pcrecpp::RE::FullMatch("abc", "[a-z]+(\\d+)?", &number);
+//
+// -----------------------------------------------------------------------
+// DO_MATCH
+//
+// The matching interface supports at most 16 arguments per call.
+// If you need more, consider using the more general interface
+// pcrecpp::RE::DoMatch().  See pcrecpp.h for the signature for DoMatch.
+//
+// -----------------------------------------------------------------------
+// PARTIAL MATCHES
+//
+// You can use the "PartialMatch" operation when you want the pattern
+// to match any substring of the text.
+//
+// Example: simple search for a string:
+//    pcrecpp::RE("ell").PartialMatch("hello");
+//
+// Example: find first number in a string:
+//    int number;
+//    pcrecpp::RE re("(\\d+)");
+//    re.PartialMatch("x*100 + 20", &number);
+//    assert(number == 100);
+//
+// -----------------------------------------------------------------------
+// UTF-8 AND THE MATCHING INTERFACE:
+//
+// By default, pattern and text are plain text, one byte per character.
+// The UTF8 flag, passed to the constructor, causes both pattern
+// and string to be treated as UTF-8 text, still a byte stream but
+// potentially multiple bytes per character. In practice, the text
+// is likelier to be UTF-8 than the pattern, but the match returned
+// may depend on the UTF8 flag, so always use it when matching
+// UTF8 text.  E.g., "." will match one byte normally but with UTF8
+// set may match up to three bytes of a multi-byte character.
+//
+// Example:
+//    pcrecpp::RE_Options options;
+//    options.set_utf8();
+//    pcrecpp::RE re(utf8_pattern, options);
+//    re.FullMatch(utf8_string);
+//
+// Example: using the convenience function UTF8():
+//    pcrecpp::RE re(utf8_pattern, pcrecpp::UTF8());
+//    re.FullMatch(utf8_string);
+//
+// NOTE: The UTF8 option is ignored if pcre was not configured with the
+//       --enable-utf8 flag.
+//
+// -----------------------------------------------------------------------
+// PASSING MODIFIERS TO THE REGULAR EXPRESSION ENGINE
+//
+// PCRE defines some modifiers to change the behavior of the regular
+// expression engine.
+// The C++ wrapper defines an auxiliary class, RE_Options, as a vehicle
+// to pass such modifiers to a RE class.
+//
+// Currently, the following modifiers are supported
+//
+//    modifier              description               Perl corresponding
+//
+//    PCRE_CASELESS         case insensitive match    /i
+//    PCRE_MULTILINE        multiple lines match      /m
+//    PCRE_DOTALL           dot matches newlines      /s
+//    PCRE_DOLLAR_ENDONLY   $ matches only at end     N/A
+//    PCRE_EXTRA            strict escape parsing     N/A
+//    PCRE_EXTENDED         ignore whitespaces        /x
+//    PCRE_UTF8             handles UTF8 chars        built-in
+//    PCRE_UNGREEDY         reverses * and *?         N/A
+//    PCRE_NO_AUTO_CAPTURE  disables matching parens  N/A (*)
+//
+// (For a full account on how each modifier works, please check the
+// PCRE API reference manual).
+//
+// (*) Both Perl and PCRE allow non matching parentheses by means of the
+// "?:" modifier within the pattern itself. e.g. (?:ab|cd) does not
+// capture, while (ab|cd) does.
+//
+// For each modifier, there are two member functions whose name is made
+// out of the modifier in lowercase, without the "PCRE_" prefix. For
+// instance, PCRE_CASELESS is handled by
+//    bool caseless(),
+// which returns true if the modifier is set, and
+//    RE_Options & set_caseless(bool),
+// which sets or unsets the modifier.
+//
+// Moreover, PCRE_EXTRA_MATCH_LIMIT can be accessed through the
+// set_match_limit() and match_limit() member functions.
+// Setting match_limit to a non-zero value will limit the executation of
+// pcre to keep it from doing bad things like blowing the stack or taking
+// an eternity to return a result.  A value of 5000 is good enough to stop
+// stack blowup in a 2MB thread stack.  Setting match_limit to zero will
+// disable match limiting.  Alternately, you can set match_limit_recursion()
+// which uses PCRE_EXTRA_MATCH_LIMIT_RECURSION to limit how much pcre
+// recurses.  match_limit() caps the number of matches pcre does;
+// match_limit_recrusion() caps the depth of recursion.
+//
+// Normally, to pass one or more modifiers to a RE class, you declare
+// a RE_Options object, set the appropriate options, and pass this
+// object to a RE constructor. Example:
+//
+//    RE_options opt;
+//    opt.set_caseless(true);
+//
+//    if (RE("HELLO", opt).PartialMatch("hello world")) ...
+//
+// RE_options has two constructors. The default constructor takes no
+// arguments and creates a set of flags that are off by default.
+//
+// The optional parameter 'option_flags' is to facilitate transfer
+// of legacy code from C programs.  This lets you do
+//    RE(pattern, RE_Options(PCRE_CASELESS|PCRE_MULTILINE)).PartialMatch(str);
+//
+// But new code is better off doing
+//    RE(pattern,
+//      RE_Options().set_caseless(true).set_multiline(true)).PartialMatch(str);
+// (See below)
+//
+// If you are going to pass one of the most used modifiers, there are some
+// convenience functions that return a RE_Options class with the
+// appropriate modifier already set:
+// CASELESS(), UTF8(), MULTILINE(), DOTALL(), EXTENDED()
+//
+// If you need to set several options at once, and you don't want to go
+// through the pains of declaring a RE_Options object and setting several
+// options, there is a parallel method that give you such ability on the
+// fly. You can concatenate several set_xxxxx member functions, since each
+// of them returns a reference to its class object.  e.g.: to pass
+// PCRE_CASELESS, PCRE_EXTENDED, and PCRE_MULTILINE to a RE with one
+// statement, you may write
+//
+//    RE(" ^ xyz \\s+ .* blah$", RE_Options()
+//                            .set_caseless(true)
+//                            .set_extended(true)
+//                            .set_multiline(true)).PartialMatch(sometext);
+//
+// -----------------------------------------------------------------------
+// SCANNING TEXT INCREMENTALLY
+//
+// The "Consume" operation may be useful if you want to repeatedly
+// match regular expressions at the front of a string and skip over
+// them as they match.  This requires use of the "StringPiece" type,
+// which represents a sub-range of a real string.  Like RE, StringPiece
+// is defined in the pcrecpp namespace.
+//
+// Example: read lines of the form "var = value" from a string.
+//    string contents = ...;                 // Fill string somehow
+//    pcrecpp::StringPiece input(contents);  // Wrap in a StringPiece
+//
+//    string var;
+//    int value;
+//    pcrecpp::RE re("(\\w+) = (\\d+)\n");
+//    while (re.Consume(&input, &var, &value)) {
+//      ...;
+//    }
+//
+// Each successful call to "Consume" will set "var/value", and also
+// advance "input" so it points past the matched text.
+//
+// The "FindAndConsume" operation is similar to "Consume" but does not
+// anchor your match at the beginning of the string.  For example, you
+// could extract all words from a string by repeatedly calling
+//     pcrecpp::RE("(\\w+)").FindAndConsume(&input, &word)
+//
+// -----------------------------------------------------------------------
+// PARSING HEX/OCTAL/C-RADIX NUMBERS
+//
+// By default, if you pass a pointer to a numeric value, the
+// corresponding text is interpreted as a base-10 number.  You can
+// instead wrap the pointer with a call to one of the operators Hex(),
+// Octal(), or CRadix() to interpret the text in another base.  The
+// CRadix operator interprets C-style "0" (base-8) and "0x" (base-16)
+// prefixes, but defaults to base-10.
+//
+// Example:
+//   int a, b, c, d;
+//   pcrecpp::RE re("(.*) (.*) (.*) (.*)");
+//   re.FullMatch("100 40 0100 0x40",
+//                pcrecpp::Octal(&a), pcrecpp::Hex(&b),
+//                pcrecpp::CRadix(&c), pcrecpp::CRadix(&d));
+// will leave 64 in a, b, c, and d.
+//
+// -----------------------------------------------------------------------
+// REPLACING PARTS OF STRINGS
+//
+// You can replace the first match of "pattern" in "str" with
+// "rewrite".  Within "rewrite", backslash-escaped digits (\1 to \9)
+// can be used to insert text matching corresponding parenthesized
+// group from the pattern.  \0 in "rewrite" refers to the entire
+// matching text.  E.g.,
+//
+//   string s = "yabba dabba doo";
+//   pcrecpp::RE("b+").Replace("d", &s);
+//
+// will leave "s" containing "yada dabba doo".  The result is true if
+// the pattern matches and a replacement occurs, or false otherwise.
+//
+// GlobalReplace() is like Replace(), except that it replaces all
+// occurrences of the pattern in the string with the rewrite.
+// Replacements are not subject to re-matching.  E.g.,
+//
+//   string s = "yabba dabba doo";
+//   pcrecpp::RE("b+").GlobalReplace("d", &s);
+//
+// will leave "s" containing "yada dada doo".  It returns the number
+// of replacements made.
+//
+// Extract() is like Replace(), except that if the pattern matches,
+// "rewrite" is copied into "out" (an additional argument) with
+// substitutions.  The non-matching portions of "text" are ignored.
+// Returns true iff a match occurred and the extraction happened
+// successfully.  If no match occurs, the string is left unaffected.

+* What happens is as follows:                                            *
+*                                                                        *
+* If the previous match was NOT for an empty string, we can just start   *
+* the next match at the end of the previous one.                         *
+*                                                                        *
+* If the previous match WAS for an empty string, we can't do that, as it *
+* would lead to an infinite loop. Instead, a special call of pcre_exec() *
+* is made with the PCRE_NOTEMPTY and PCRE_ANCHORED flags set. The first  *
+* of these tells PCRE that an empty string is not a valid match; other   *
+* possibilities must be tried. The second flag restricts PCRE to one     *
+* match attempt at the initial string position. If this match succeeds,  *
+* an alternative to the empty string match has been found, and we can    *
+* proceed round the loop.                                                *

+
+     (4) The 0x001fffff bits contain the code point. No Unicode code point will
+         ever be greater than 0x0010ffff, so this should be OK for ever.
+
+(f1) (1) The 0xfc000000 bits contain the character type number. The numbers are
+         defined by an enum in ucp.h.
+
+     (2) The 0x03ff0000 bits are spare.
+
+     (3) The 0x0000ffff bits contain EITHER the unsigned offset to the top of
+         range if this entry defines a range, OR the *signed* offset to the
+         character's "other case" partner if this entry defines a single
+         character. There is no partner if the value is zero.

+
+The upper/lower casing information is set only for characters that come in
+pairs. The non-one-to-one mappings in the Unicode data are ignored.
+
+When searching the data, proceed as follows:
+
+(1) Set up for a binary chop search.
+
+(2) If the top is not greater than the bottom, the character is not in the
+    table. Its type must therefore be "Cn" ("Undefined").
+
+(3) Find the middle vector element.
+
+(4) Extract the code point and compare. If equal, we are done.
+
+(5) If the test character is smaller, set the top to the current point, and
+    goto (2).
+
+(6) If the current entry defines a range, compute the last character by adding
+    the offset, and see if the test character is within the range. If it is,
+    we are done.
+
+(7) Otherwise, set the bottom to one element past the current point and goto
+    (2).
