function match_all_full(string: Array(String), start_position: Number(gint), match_options: GLib.RegexMatchFlags): [ok: Boolean, match_info: GLib.MatchInfo] {
    // Gjs wrapper for g_regex_match_all_full()

Using the standard algorithm for regular expression matching only the longest match in the string is retrieved, it is not possible to obtain all the available matches. 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 GLib.MatchInfo.prototype.get_match_count. To obtain the matched strings and their position you can use, respectively, GLib.MatchInfo.prototype.fetch and GLib.MatchInfo.prototype.fetch_pos. 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 start_position differs from just passing over a shortened string and setting #G_REGEX_MATCH_NOTBOL in the case of a pattern that begins with any kind of lookbehind assertion, such as "\b".

A GLib.MatchInfo structure, used to get information on the match, is stored in match_info if not null. Note that if match_info is not null then it is created even if the function returns false, i.e. you must free it regardless if regular expression actually matched.

string is not copied and is used in GLib.MatchInfo internally. If you use any GLib.MatchInfo method (except after freeing or modifying string then the behaviour is undefined.

Since 2.14


the string to scan for matches


starting index of the string to match


match options


true is the string matched, false otherwise


pointer to location where to store the GLib.MatchInfo, or null if you do not need it
