220 * GRegexCompileFlags:
221 * @G_REGEX_DEFAULT: No special options set. Since: 2.74
222 * @G_REGEX_CASELESS: Letters in the pattern match both upper- and
223 * lowercase letters. This option can be changed within a pattern
224 * by a "(?i)" option setting.
225 * @G_REGEX_MULTILINE: By default, GRegex treats the strings as consisting
226 * of a single line of characters (even if it actually contains
227 * newlines). The "start of line" metacharacter ("^") matches only
228 * at the start of the string, while the "end of line" metacharacter
229 * ("$") matches only at the end of the string, or before a terminating
230 * newline (unless %G_REGEX_DOLLAR_ENDONLY is set). When
231 * %G_REGEX_MULTILINE is set, the "start of line" and "end of line"
232 * constructs match immediately following or immediately before any
233 * newline in the string, respectively, as well as at the very start
234 * and end. This can be changed within a pattern by a "(?m)" option
236 * @G_REGEX_DOTALL: A dot metacharacter (".") in the pattern matches all
237 * characters, including newlines. Without it, newlines are excluded.
238 * This option can be changed within a pattern by a ("?s") option setting.
239 * @G_REGEX_EXTENDED: Whitespace data characters in the pattern are
240 * totally ignored except when escaped or inside a character class.
241 * Whitespace does not include the VT character (code 11). In addition,
242 * characters between an unescaped "#" outside a character class and
243 * the next newline character, inclusive, are also ignored. This can
244 * be changed within a pattern by a "(?x)" option setting.
245 * @G_REGEX_ANCHORED: The pattern is forced to be "anchored", that is,
246 * it is constrained to match only at the first matching point in the
247 * string that is being searched. This effect can also be achieved by
248 * appropriate constructs in the pattern itself such as the "^"
250 * @G_REGEX_DOLLAR_ENDONLY: A dollar metacharacter ("$") in the pattern
251 * matches only at the end of the string. Without this option, a
252 * dollar also matches immediately before the final character if
253 * it is a newline (but not before any other newlines). This option
254 * is ignored if %G_REGEX_MULTILINE is set.
255 * @G_REGEX_UNGREEDY: Inverts the "greediness" of the quantifiers so that
256 * they are not greedy by default, but become greedy if followed by "?".
257 * It can also be set by a "(?U)" option setting within the pattern.
258 * @G_REGEX_RAW: Usually strings must be valid UTF-8 strings, using this
259 * flag they are considered as a raw sequence of bytes.
260 * @G_REGEX_NO_AUTO_CAPTURE: Disables the use of numbered capturing
261 * parentheses in the pattern. Any opening parenthesis that is not
262 * followed by "?" behaves as if it were followed by "?:" but named
263 * parentheses can still be used for capturing (and they acquire numbers
265 * @G_REGEX_OPTIMIZE: Since 2.74 and the port to pcre2, requests JIT
266 * compilation, which, if the just-in-time compiler is available, further
267 * processes a compiled pattern into machine code that executes much
268 * faster. However, it comes at the cost of extra processing before the
269 * match is performed, so it is most beneficial to use this when the same
270 * compiled pattern is used for matching many times. Before 2.74 this
271 * option used the built-in non-JIT optimizations in pcre1.
272 * @G_REGEX_FIRSTLINE: Limits an unanchored pattern to match before (or at) the
273 * first newline. Since: 2.34
274 * @G_REGEX_DUPNAMES: Names used to identify capturing subpatterns need not
275 * be unique. This can be helpful for certain types of pattern when it
276 * is known that only one instance of the named subpattern can ever be
278 * @G_REGEX_NEWLINE_CR: Usually any newline character or character sequence is
279 * recognized. If this option is set, the only recognized newline character
281 * @G_REGEX_NEWLINE_LF: Usually any newline character or character sequence is
282 * recognized. If this option is set, the only recognized newline character
284 * @G_REGEX_NEWLINE_CRLF: Usually any newline character or character sequence is
285 * recognized. If this option is set, the only recognized newline character
286 * sequence is '\r\n'.
287 * @G_REGEX_NEWLINE_ANYCRLF: Usually any newline character or character sequence
288 * is recognized. If this option is set, the only recognized newline character
289 * sequences are '\r', '\n', and '\r\n'. Since: 2.34
290 * @G_REGEX_BSR_ANYCRLF: Usually any newline character or character sequence
291 * is recognised. If this option is set, then "\R" only recognizes the newline
292 * characters '\r', '\n' and '\r\n'. Since: 2.34
293 * @G_REGEX_JAVASCRIPT_COMPAT: Changes behaviour so that it is compatible with
294 * JavaScript rather than PCRE. Since GLib 2.74 this is no longer supported,
295 * as libpcre2 does not support it. Since: 2.34 Deprecated: 2.74
