{-# LANGUAGE TypeApplications #-} -- | Copyright : Will Thompson and Iñaki García Etxebarria -- License : LGPL-2.1 -- Maintainer : Iñaki García Etxebarria -- -- A @GRegex@ is a compiled form of a regular expression. -- -- After instantiating a @GRegex@, you can use its methods to find matches -- in a string, replace matches within a string, or split the string at matches. -- -- @GRegex@ implements regular expression pattern matching using syntax and -- semantics (such as character classes, quantifiers, and capture groups) -- similar to Perl regular expression. See the -- <http://developer.gnome.org/glib/stable/man:pcre2pattern(3 PCRE documentation>) for details. -- -- A typical scenario for regex pattern matching is to check if a string -- matches a pattern. The following statements implement this scenario. -- -- -- === /{ .c } code/ -- >const char *regex_pattern = ".*GLib.*"; -- >const char *string_to_search = "You will love the GLib implementation of regex"; -- >g_autoptr(GMatchInfo) match_info = NULL; -- >g_autoptr(GRegex) regex = NULL; -- > -- >regex = g_regex_new (regex_pattern, G_REGEX_DEFAULT, G_REGEX_MATCH_DEFAULT, NULL); -- >g_assert (regex != NULL); -- > -- >if (g_regex_match (regex, string_to_search, G_REGEX_MATCH_DEFAULT, &match_info)) -- > { -- > int start_pos, end_pos; -- > g_match_info_fetch_pos (match_info, 0, &start_pos, &end_pos); -- > g_print ("Match successful! Overall pattern matches bytes %d to %d\n", start_pos, end_pos); -- > } -- >else -- > { -- > g_print ("No match!\n"); -- > } -- -- -- The constructor for @GRegex@ includes two sets of bitmapped flags: -- -- * [flags/@gLib@/.RegexCompileFlags]—These flags -- control how GLib compiles the regex. There are options for case -- sensitivity, multiline, ignoring whitespace, etc. -- * [flags/@gLib@/.RegexMatchFlags]—These flags control -- @GRegex@’s matching behavior, such as anchoring and customizing definitions -- for newline characters. -- -- Some regex patterns include backslash assertions, such as @\\d@ (digit) or -- @\\D@ (non-digit). The regex pattern must escape those backslashes. For -- example, the pattern @\"\\\\d\\\\D\"@ matches a digit followed by a non-digit. -- -- GLib’s implementation of pattern matching includes a @start_position@ -- argument for some of the match, replace, and split methods. Specifying -- a start position provides flexibility when you want to ignore the first -- _n_ characters of a string, but want to incorporate backslash assertions -- at character _n_ - 1. For example, a database field contains inconsistent -- spelling for a job title: @healthcare provider@ and @health-care provider@. -- The database manager wants to make the spelling consistent by adding a -- hyphen when it is missing. The following regex pattern tests for the string -- @care@ preceded by a non-word boundary character (instead of a hyphen) -- and followed by a space. -- -- -- === /{ .c } code/ -- >const char *regex_pattern = "\\Bcare\\s"; -- -- -- An efficient way to match with this pattern is to start examining at -- @start_position@ 6 in the string @healthcare@ or @health-care@. -- -- -- === /{ .c } code/ -- >const char *regex_pattern = "\\Bcare\\s"; -- >const char *string_to_search = "healthcare provider"; -- >g_autoptr(GMatchInfo) match_info = NULL; -- >g_autoptr(GRegex) regex = NULL; -- > -- >regex = g_regex_new ( -- > regex_pattern, -- > G_REGEX_DEFAULT, -- > G_REGEX_MATCH_DEFAULT, -- > NULL); -- >g_assert (regex != NULL); -- > -- >g_regex_match_full ( -- > regex, -- > string_to_search, -- > -1, -- > 6, // position of 'c' in the test string. -- > G_REGEX_MATCH_DEFAULT, -- > &match_info, -- > NULL); -- -- -- The method 'GI.GLib.Structs.Regex.regexMatchFull' (and other methods implementing -- @start_pos@) allow for lookback before the start position to determine if -- the previous character satisfies an assertion. -- -- Unless you set the [flags/@gLib@/.RegexCompileFlags.RAW] as one of -- the @GRegexCompileFlags@, all the strings passed to @GRegex@ methods must -- be encoded in UTF-8. The lengths and the positions inside the strings are -- in bytes and not in characters, so, for instance, @\\xc3\\xa0@ (i.e., @à@) -- is two bytes long but it is treated as a single character. If you set -- @G_REGEX_RAW@, the strings can be non-valid UTF-8 strings and a byte is -- treated as a character, so @\\xc3\\xa0@ is two bytes and two characters long. -- -- Regarding line endings, @\\n@ matches a @\\n@ character, and @\\r@ matches -- a @\\r@ character. More generally, @\\R@ matches all typical line endings: -- CR + LF (@\\r\\n@), LF (linefeed, U+000A, @\\n@), VT (vertical tab, U+000B, -- @\\v@), FF (formfeed, U+000C, @\\f@), CR (carriage return, U+000D, @\\r@), -- NEL (next line, U+0085), LS (line separator, U+2028), and PS (paragraph -- separator, U+2029). -- -- The behaviour of the dot, circumflex, and dollar metacharacters are -- affected by newline characters. By default, @GRegex@ matches any newline -- character matched by @\\R@. You can limit the matched newline characters by -- specifying the [flags/@gLib@/.RegexMatchFlags.NEWLINE_CR], -- [flags/@gLib@/.RegexMatchFlags.NEWLINE_LF], and -- [flags/@gLib@/.RegexMatchFlags.NEWLINE_CRLF] compile options, and -- with [flags/@gLib@/.RegexMatchFlags.NEWLINE_ANY], -- [flags/@gLib@/.RegexMatchFlags.NEWLINE_CR], -- [flags/@gLib@/.RegexMatchFlags.NEWLINE_LF] and -- [flags/@gLib@/.RegexMatchFlags.NEWLINE_CRLF] match options. -- These settings are also relevant when compiling a pattern if -- [flags/@gLib@/.RegexCompileFlags.EXTENDED] is set and an unescaped -- @#@ outside a character class is encountered. This indicates a comment -- that lasts until after the next newline. -- -- Because @GRegex@ does not modify its internal state between creation and -- destruction, you can create and modify the same @GRegex@ instance from -- different threads. In contrast, t'GI.GLib.Structs.MatchInfo.MatchInfo' is not thread safe. -- -- The regular expression low-level functionalities are obtained through -- the excellent <http://www.pcre.org/ PCRE> library

For instance matching -- @\"\<a> \<b> \<c>\"@ against the pattern @\"\<.*>\"@ -- you get @\"\<a> \<b> \<c>\"@. -- -- This function uses a different algorithm (called DFA, i.e. deterministic -- finite automaton), so it can retrieve all the possible matches, all -- starting at the same point in the string. For instance matching -- @\"\<a> \<b> \<c>\"@ against the pattern @\"\<.*>\"@ -- you would obtain three matches: @\"\<a> \<b> \<c>\"@, -- @\"\<a> \<b>\"@ and @\"\<a>\"@. -- -- The number of matched strings is retrieved using -- 'GI.GLib.Structs.MatchInfo.matchInfoGetMatchCount'.

Note that the strings are returned in -- reverse order of length; that is, the longest matching string is -- given first. -- -- Note that the DFA algorithm is slower than the standard one and it -- is not able to capture substrings, so backreferences do not work. -- -- Setting /@startPosition@/ differs from just passing over a shortened -- string and setting 'GI.GLib.Flags.RegexMatchFlagsNotbol' in the case of a pattern -- that begins with any kind of lookbehind assertion, such as \"\\b\". -- -- Unless 'GI.GLib.Flags.RegexCompileFlagsRaw' is specified in the options, /@string@/ must be valid UTF-8. -- -- A t'GI.GLib.Structs.MatchInfo.MatchInfo' structure, used to get information on the match, is -- stored in /@matchInfo@/ if not 'P.Nothing'.
