.TH SYS-TOKENIZE 2 .SH NAME tokenize \- split string into words .SH SYNOPSIS .EX include "sys.m"; sys := load Sys Sys->PATH; tokenize: fn(s, delim: string): (int, list of string); .EE .SH DESCRIPTION .B Tokenize breaks .I s into words separated by characters in .IR delim . The returned tuple holds the number of words and an ordered list of those words (whose .B hd gives the leftmost word from .IR s ). .PP Words are delimited by the maximal sequences of any character from the .I delim string. .B Tokenize skips delimiter characters at the beginning and end of .IR s , so each element in the returned list has non-zero length. .PP If .I s is .B nil or contains no words, .B tokenize returns a count of zero and a .B nil list. .PP .I Delim may be .B nil or the empty string, specifying no delimiter characters. The resulting word list will be .B nil (if .I s is .B nil or the empty string) or a single-item list with a copy of .IR s . .SH SEE ALSO .IR sys-intro (2)
