Constant Summary

CASELESS =

Letters in the pattern match both upper- and

lowercase letters. This option can be changed within a pattern
by a "(?i)" option setting.

1 or :caseless

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.

2 or :multiline

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.

4 or :dotall

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.

8 or :extended

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.

16 or :anchored

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.

32 or :dollar_endonly

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.

512 or :ungreedy

RAW =

Usually strings must be valid UTF-8 strings, using this

flag they are considered as a raw sequence of bytes.

2048 or :raw

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).

4096 or :no_auto_capture

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.

8192 or :optimize

FIRSTLINE =

Limits an unanchored pattern to match before (or at) the

first newline. Since: 2.34

262144 or :firstline

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.

524288 or :dupnames

NEWLINE_CR =

Usually any newline character or character sequence is

recognized. If this option is set, the only recognized newline character
is '\r'.

1048576 or :newline_cr

NEWLINE_LF =

Usually any newline character or character sequence is

recognized. If this option is set, the only recognized newline character
is '\n'.

2097152 or :newline_lf

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'.

3145728 or :newline_crlf

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

5242880 or :newline_anycrlf

BSR_ANYCRLF =

Usually any newline character or character sequence

 is recognised. If this option is set, then "\R" only recognizes the newline
characters '\r', '\n' and '\r\n'. Since: 2.34

8388608 or :bsr_anycrlf

JAVASCRIPT_COMPAT =

Changes behaviour so that it is compatible with

JavaScript rather than PCRE. Since: 2.34

33554432 or :javascript_compat
