This option can be changed within a pattern * by a "(?i)" option setting. * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting * of a single line of characters (even if it actually contains * newlines). The "start of line" metacharacter ("^") matches only * at the start of the string, while the "end of line" metacharacter * ("$") matches only at the end of the string, or before a terminating * newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When * #G_REGEX_MULTILINE is set, the "start of line" and "end of line" * constructs match immediately following or immediately before any * newline in the string, respectively, as well as at the very start * and end. This can be changed within a pattern by a "(?m)" option * setting. * @G_REGEX_DOTALL: A dot metacharacter (".") in the pattern matches all * characters, including newlines. Without it, newlines are excluded. * This option can be changed within a pattern by a ("?s") option setting. * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are * totally ignored except when escaped or inside a character class. * Whitespace does not include the VT character (code 11). In addition, * characters between an unescaped "#" outside a character class and * the next newline character, inclusive, are also ignored. This can * be changed within a pattern by a "(?x)" option setting. * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is, * it is constrained to match only at the first matching point in the * string that is being searched. This effect can also be achieved by * appropriate constructs in the pattern itself such as the "^" * metacharacter. * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern * matches only at the end of the string. Without this option, a * dollar also matches immediately before the final character if * it is a newline (but not before any other newlines). This option * is ignored if #G_REGEX_MULTILINE is set. * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that * they are not greedy by default, but become greedy if followed by "?". * It can also be set by a "(?U)" option setting within the pattern. * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this * flag they are considered as a raw sequence of bytes. * @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing * parentheses in the pattern. Any opening parenthesis that is not * followed by "?" behaves as if it were followed by "?:" but named * parentheses can still be used for capturing (and they acquire numbers * in the usual way). * @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will * be used many times, then it may be worth the effort to optimize it * to improve the speed of matches. * @G_REGEX_FIRSTLINE: Limits an unanchored pattern to match before (or at) the * first newline. Since: 2.34 * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not * be unique. This can be helpful for certain types of pattern when it * is known that only one instance of the named subpattern can ever be * matched. * @G_REGEX_NEWLINE_CR: Usually any newline character or character sequence is * recognized. If this option is set, the only recognized newline character * is '\r'. * @G_REGEX_NEWLINE_LF: Usually any newline character or character sequence is * recognized. If this option is set, the only recognized newline character * is '\n'. * @G_REGEX_NEWLINE_CRLF: Usually any newline character or character sequence is * recognized. If this option is set, the only recognized newline character * sequence is '\r\n'. * @G_REGEX_NEWLINE_ANYCRLF: Usually any newline character or character sequence * is recognized. If this option is set, the only recognized newline character * sequences are '\r', '\n', and '\r\n'. Since: 2.34 * @G_REGEX_BSR_ANYCRLF: Usually any newline character or character sequence * is recognised.
