Glob2re - convert glob/wildcard to regular expression
The module exports one function, glob2re:
use Glob2re; my $re = glob2re($glob);
The glob2re function converts a Unix-style file-globbing string to a regular expression. It is used by the dirlist and hgrep commands.
Unix-style file-globbing uses "*" to match zero or more characters of any type, and "?" to match any single character. Prefix "*" or "?" with "\" if you want to use those literally, rather than as a metacharacter.
my $glob = "*.*"; my $re = glob2re($glob);
