-#ifndef _PCRECPP_H
-#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.

+//
+// -----------------------------------------------------------------------
+// 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.
