The type for regexps.

The type for match result.

Simple regexp constructor.

Same as regexp but matching will be performed in a case insensitive way.

Regexp constructor with flag that allow for case-insensitive search or multiline search (the global flag is always set).

Escapes characters with special meaning in the regexp context.

regexp_string s creates a regexp matching the exact string s.

Same as regexp_string but matching will be performed in a case insensitive way.

string_match r s i matches the string s starting from the ith character. Evaluates to None if s (from the ith character) doesn't match r.

search r s i evaluates to the index of the match and the match result or None if s (starting from i) doesn't match r.

Same as search.

matched_string r return the exact substring that matched when evaluating r.

matched_group r i is the ith group matched. Groups in matches are * obtained with parentheses. Groups are 1-based.

global_replace r s by replaces all of the matches of r in s by by.

replace_first r s by replaces the first match of r in s by by.

split r s splits the string s erasing matches with r. split (regexp " ") "toto tutu tata" is ["toto";"tutu";"tata"].

bounded_split r s i is like split r s except that the result's length is less than i.
