Name Description
G_REGEX_MATCH_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_MATCH_NOTBOL

Specifies that first character of the string is not the beginning of a line, so the circumflex metacharacter should not match before it. Setting this without #G_REGEX_MULTILINE (at compile time) causes circumflex never to match. This option affects only the behaviour of the circumflex metacharacter, it does not affect “\A”.

G_REGEX_MATCH_NOTEOL

Specifies that the end of the subject string is not the end of a line, so the dollar metacharacter should not match it nor (except in multiline mode) a newline immediately before it. Setting this without #G_REGEX_MULTILINE (at compile time) causes dollar never to match. This option affects only the behaviour of the dollar metacharacter, it does not affect “\Z” or “\z”.

G_REGEX_MATCH_NOTEMPTY

An empty string is not considered to be a valid match if this option is set. If there are alternatives in the pattern, they are tried. If all the alternatives match the empty string, the entire match fails. For example, if the pattern “a?b?” is applied to a string not beginning with “a” or “b”, it matches the empty string at the start of the string. With this flag set, this match is not valid, so GRegex searches further into the string for occurrences of “a” or “b”.

G_REGEX_MATCH_PARTIAL

Turns on the partial matching feature, for more documentation on partial matching see g_match_info_is_partial_match().

G_REGEX_MATCH_NEWLINE_CR

Overrides the newline definition set when creating a new GRegex, setting the ‘\r’ character as line terminator.

G_REGEX_MATCH_NEWLINE_LF

Overrides the newline definition set when creating a new GRegex, setting the ‘\n’ character as line terminator.

G_REGEX_MATCH_NEWLINE_CRLF

Overrides the newline definition set when creating a new GRegex, setting the ‘\r\n’ characters sequence as line terminator.

G_REGEX_MATCH_NEWLINE_ANY

Overrides the newline definition set when creating a new GRegex, any Unicode newline sequence is recognised as a newline. These are ‘\r’, ‘\n’ and ‘\rn’, and the single characters U+000B LINE TABULATION, U+000C FORM FEED (FF), U+0085 NEXT LINE (NEL), U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR.

G_REGEX_MATCH_NEWLINE_ANYCRLF

Overrides the newline definition set when creating a new GRegex; any ‘\r’, ‘\n’, or ‘\r\n’ character sequence is recognized as a newline. Since: 2.34

G_REGEX_MATCH_BSR_ANYCRLF

Overrides the newline definition for “\R” set when creating a new GRegex; only ‘\r’, ‘\n’, or ‘\r\n’ character sequences are recognized as a newline by “\R”. Since: 2.34

G_REGEX_MATCH_BSR_ANY

Overrides the newline definition for “\R” set when creating a new GRegex; any Unicode newline character or character sequence are recognized as a newline by “\R”. These are ‘\r’, ‘\n’ and ‘\rn’, and the single characters U+000B LINE TABULATION, U+000C FORM FEED (FF), U+0085 NEXT LINE (NEL), U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR. Since: 2.34

G_REGEX_MATCH_PARTIAL_SOFT

An alias for #G_REGEX_MATCH_PARTIAL. Since: 2.34

G_REGEX_MATCH_PARTIAL_HARD

Turns on the partial matching feature. In contrast to to #G_REGEX_MATCH_PARTIAL_SOFT, this stops matching as soon as a partial match is found, without continuing to search for a possible complete match. See g_match_info_is_partial_match() for more information. Since: 2.34

G_REGEX_MATCH_NOTEMPTY_ATSTART

Like #G_REGEX_MATCH_NOTEMPTY, but only applied to the start of the matched string. For anchored patterns this can only happen for pattern containing “\K”. Since: 2.34
