re_split(+Pattern, +String, -Split:list) is det

re_split(+Pattern, +String, -Split:list, +Options) is det

Split String using the regular expression Pattern. Split is a list of strings holding alternating matches of Pattern and skipped parts of the String, starting with a skipped part. The Split lists ends with a string of the content of String after the last match. If Pattern does not appear in String, Split is a list holding a copy of String. This implies the number of elements in Split is always odd. For example:

?- re_split("a+", "abaac", Split, []).
Split = ["","a","b","aa","c"].
?- re_split(":\\s*"/n, "Age: 33", Split, []).
Split = ['Age', ': ', 33].

Arguments:

Pattern - is the pattern text, optionally follows by /Flags. Similar to re_matchsub/4, the final output type can be controlled by a flag a (atom), s (string, default) or n (number if possible, atom otherwise).
