type regexp

The type for regexps.

type result

The type for match result.


val regexp : string -> regexp

Simple regexp constructor.

val regexp_case_fold : string -> regexp

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

val regexp_with_flag : string -> string -> regexp

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

val quote : string -> string

Escapes characters with special meaning in the regexp context.

val regexp_string : string -> regexp

regexp_string s creates a regexp matching the exact string s.

val regexp_string_case_fold : string -> regexp

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


val string_match : regexp -> string -> int -> result option

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.

val search_forward : regexp -> string -> int -> (int * result) option

Same as search.

val matched_string : result -> string

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

val matched_group : result -> int -> string option

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

val global_replace : regexp -> string -> string -> string

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

val replace_first : regexp -> string -> string -> string

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

val split : regexp -> string -> string list

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

val bounded_split : regexp -> string -> int -> string list

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