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).

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 metacharater (".") 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 "^" + * metacharater. + * @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.
