.TH FILEPAT 2 .SH NAME filepat: expand, match \- file pattern matching .SH SYNOPSIS .EX include "filepat.m"; filepat := load Filepat Filepat->PATH; expand: fn(pat: string): list of string; match: fn(pat, name: string): int; .EE .SH DESCRIPTION .B Expand builds a list of file names in alphabetical order that match the pattern .IR pat . The pattern is tokenised using .B / as a delimiter. .PP .B Match returns 1 if .I name matches the pattern .IR pat , and 0 otherwise. .PP The .I pat passed to .B match and .B expand may include combinations of the special characters .BR * , .BR ? , .BR [ , and .BR ] . .PP The asterisk .B * matches a string of zero or more characters. .PP The query .B ? matches any single character. .PP The notation .BI [ s ]\f1, where .I s is a nonempty string, matches any single character in .IR s . The notation .BI [^ s ]\f1, where .IR s is a nonempty string, matches any single character not in .IR s . The characters .BR * , .BR ? , and .BR [ have no special meaning within s. .PP If any character is preceded by the character .BR \e , that character loses any special meaning and is interpreted literally. .SH SOURCE .B /appl/lib/filepat.b .SH SEE ALSO .IR sys-tokenize (2), .IR readdir (2) .IR regex (2)
