replace2

Replaces a search match by another text.

If match_start and match_end doesn't correspond to a search match, false is returned.

Unlike with replace, the match_start and match_end iters are revalidated to point to the replacement text boundaries.

For a regular expression replacement, you can check if replace is valid by calling check_replacement. The replace text can contain backreferences; read the replace documentation for more details.

Parameters:

this	a SourceSearchContext.
match_start	the start of the match to replace.
match_end	the end of the match to replace.
replace	the replacement text.
replace_length	the length of replace in bytes, or -1.

Returns:

whether the match has been replaced.
