function get_match_count(): Number(gint) {
    // Gjs wrapper for g_match_info_get_match_count()

Retrieves the number of matched substrings (including substring 0, that is the whole matched text), so 1 is returned if the pattern has no substrings in it and 0 is returned if the match failed.

If the last match was obtained using the DFA algorithm, that is using GLib.Regex.prototype.match_all or GLib.Regex.prototype.match_all_full, the retrieved count is not that of the number of capturing parentheses but that of the number of matched substrings.

Since 2.14


Number of matched substrings, or -1 if an error occurred
