- (string-split string delimiter [grammar limit start end]) → listprocedure
Returns a list of strings representing the words contained in the substring of string. The delimiter is a string to be used as the word separator. This will often be a single character, but multiple characters are allowed for use cases such as splitting on "\r\n". The returned list will have one more item than the number of non-overlapping occurrences of the delimiter in the string. If delimiter is an empty string, then the returned list contains a list of strings, each of which contains a single character. (Not a SRFI 13 procedure; replaces string-tokenize).
The grammar is a symbol with the same meaning as in the string-join procedure. If it is infix, which is the default, processing is done as described above, except an empty string produces the empty list; if grammar is strict-infix, then an empty string signals an error. The values prefix and suffix cause a leading/trailing empty string in the result to be suppressed.
If limit is a non-negative exact integer, at most that many splits occur, and the remainder of string is returned as the final element of the list (so the result will have at most limit + 1 elements). If limit is not specified or is #f, then as many splits as possible are made. It is an error if limit is any other value.
To split on a regular expression, use SRFI 115's regexp-split procedure. (irregex-split from the irregex module.)
Compatibility note: Don't confuse this with the similar string-split procedure from (chicken string).
