filepat: expand, match - file pattern matching

Synopsis

include "lib.m";
filepat:= load Filepat Filepat->PATH;
expand:   fn(pat: string)      : list of string;
match:    fn(pat, name: string): int;

Description


expand (pat)	The expand function builds a list of file names in alphabetical order that matches the pattern pat. The pattern is tokenized using / as a delimiter.
match (pat, name)	The `match` function returns the length of name if it matches the pattern pat. Otherwise, it returns 0.

The pat passed to match and each token of pat passed to expand may include combinations of the special characters *,?, [, and].

The asterisk * matches a string of zero or more characters.

The query ? matches any single character.

The notation [s], where s is a non-empty string, matches any single character in s. A range of characters can be expressed by a string s of the form c_start-c_end. The notation [^s], where s is a non-empty string, matches any single character not in s. The characters *,?, and [ lose their special meaning if they occur in s.

If any character is preceded by the character \, that character loses any special meaning and is interpreted literally.
