GLibRegexreplace
since: 2.14
Declaration [src]
gchar*
g_regex_replace (
const GRegex* regex,
const gchar* string,
gssize string_len,
gint start_position,
const gchar* replacement,
GRegexMatchFlags match_options,
GError** error
)
Description [src]
Replaces all occurrences of the pattern in regex with the
replacement text. Backreferences of the form \number or
\g<number> in the replacement text are interpolated by the
number-th captured subexpression of the match, \g<name> refers
to the captured subexpression with the given name. \0 refers
to the complete match, but \0 followed by a number is the octal
representation of a character. To include a literal \ in the
replacement, write \\\\.
There are also escapes that changes the case of the following text:
- \l: Convert to lower case the next character
- \u: Convert to upper case the next character
- \L: Convert to lower case till \E
- \U: Convert to upper case till \E
- \E: End case modification
If you do not need to use backreferences use g_regex_replace_literal().
The replacement string must be UTF-8 encoded even if G_REGEX_RAW was
passed to g_regex_new(). If you want to use not UTF-8 encoded strings
you can use g_regex_replace_literal().
Setting start_position differs from just passing over a shortened
string and setting G_REGEX_MATCH_NOTBOL in the case of a pattern that
begins with any kind of lookbehind assertion, such as “\b”.

Parameters
string-
Type: An array of
gcharThe string to perform matches against.
The length of the array is specified in the string_lenargument.The data is owned by the caller of the method. Each element is a NUL terminated UTF-8 string. string_len-
Type:
gssizeThe length of
string, in bytes, or -1 ifstringis nul-terminated. start_position-
Type:
gintStarting index of the string to match, in bytes.
replacement-
Type:
const gchar*Text to replace each match with.
The data is owned by the caller of the method. The value is a NUL terminated UTF-8 string. match_options-
Type:
GRegexMatchFlagsOptions for the match.
error-
