219 * @G_REGEX_CASELESS: Letters in the pattern match both upper- and
220 * lowercase letters. This option can be changed within a pattern
221 * by a "(?i)" option setting.
222 * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting
223 * of a single line of characters (even if it actually contains
224 * newlines). The "start of line" metacharacter ("^") matches only
225 * at the start of the string, while the "end of line" metacharacter
226 * ("$") matches only at the end of the string, or before a terminating
227 * newline (unless #G_REGEX_DOLLAR_ENDONLY is set). When
228 * #G_REGEX_MULTILINE is set, the "start of line" and "end of line"
229 * constructs match immediately following or immediately before any
230 * newline in the string, respectively, as well as at the very start
231 * and end. This can be changed within a pattern by a "(?m)" option
233 * @G_REGEX_DOTALL: A dot metacharater (".") in the pattern matches all
234 * characters, including newlines. Without it, newlines are excluded.
235 * This option can be changed within a pattern by a ("?s") option setting.
236 * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are
237 * totally ignored except when escaped or inside a character class.
238 * Whitespace does not include the VT character (code 11). In addition,
239 * characters between an unescaped "#" outside a character class and
240 * the next newline character, inclusive, are also ignored. This can
241 * be changed within a pattern by a "(?x)" option setting.
242 * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is,
243 * it is constrained to match only at the first matching point in the
244 * string that is being searched. This effect can also be achieved by
245 * appropriate constructs in the pattern itself such as the "^"
247 * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern
248 * matches only at the end of the string. Without this option, a
249 * dollar also matches immediately before the final character if
250 * it is a newline (but not before any other newlines). This option
251 * is ignored if #G_REGEX_MULTILINE is set.
252 * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that
253 * they are not greedy by default, but become greedy if followed by "?".
254 * It can also be set by a "(?U)" option setting within the pattern.
255 * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this
256 * flag they are considered as a raw sequence of bytes.
257 * @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing
258 * parentheses in the pattern. Any opening parenthesis that is not
259 * followed by "?" behaves as if it were followed by "?:" but named
260 * parentheses can still be used for capturing (and they acquire numbers
262 * @G_REGEX_OPTIMIZE: Optimize the regular expression. If the pattern will
263 * be used many times, then it may be worth the effort to optimize it
264 * to improve the speed of matches.
265 * @G_REGEX_FIRSTLINE: Limits an unanchored pattern to match before (or at) the
266 * first newline. Since: 2.34
267 * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not
268 * be unique. This can be helpful for certain types of pattern when it
269 * is known that only one instance of the named subpattern can ever be
271 * @G_REGEX_NEWLINE_CR: Usually any newline character or character sequence is
272 * recognized. If this option is set, the only recognized newline character
274 * @G_REGEX_NEWLINE_LF: Usually any newline character or character sequence is
275 * recognized. If this option is set, the only recognized newline character
277 * @G_REGEX_NEWLINE_CRLF: Usually any newline character or character sequence is
278 * recognized. If this option is set, the only recognized newline character
279 * sequence is '\r\n'.
280 * @G_REGEX_NEWLINE_ANYCRLF: Usually any newline character or character sequence
281 * is recognized. If this option is set, the only recognized newline character
282 * sequences are '\r', '\n', and '\r\n'. Since: 2.34
283 * @G_REGEX_BSR_ANYCRLF: Usually any newline character or character sequence
284 * is recognised. If this option is set, then "\R" only recognizes the newline
285 * characters '\r', '\n' and '\r\n'. Since: 2.34
286 * @G_REGEX_JAVASCRIPT_COMPAT: Changes behaviour so that it is compatible with
287 * JavaScript rather than PCRE. Since: 2.34

324 * @G_REGEX_MATCH_NOTBOL: Specifies that first character of the string is
325 * not the beginning of a line, so the circumflex metacharacter should
326 * not match before it. Setting this without #G_REGEX_MULTILINE (at
327 * compile time) causes circumflex never to match. This option affects
328 * only the behaviour of the circumflex metacharacter, it does not
330 * @G_REGEX_MATCH_NOTEOL: Specifies that the end of the subject string is
331 * not the end of a line, so the dollar metacharacter should not match
332 * it nor (except in multiline mode) a newline immediately before it.
333 * Setting this without #G_REGEX_MULTILINE (at compile time) causes

337 * match if this option is set. If there are alternatives in the pattern,
338 * they are tried. If all the alternatives match the empty string, the
339 * entire match fails. For example, if the pattern "a?b?" is applied to
