SYNOPSIS
use Regexp::Wildcards qw/wc2re/;
DESCRIPTION
In many situations, users may want to specify patterns to match but
don't need the full power of regexps. Wildcards make one of those sets
- of simplified rules. This module converts wildcards expressions to Perl
+ of simplified rules. This module converts wildcard expressions to Perl
regular expressions, so that you can use them for matching. It handles
the "*" and "?" jokers, as well as Unix bracketed alternatives "{,}",
and uses the backspace ("\") as an escape character. Wrappers are
provided to mimic the behaviour of Windows and Unix shells.
-EXPORT
- Four functions are exported only on request : "wc2re", "wc2re_unix",
- "wc2re_win32" and "wc2re_jokers".

FUNCTIONS
"wc2re_unix"
This function takes as its only argument the wildcard string to process,
"{" and "}". Commas outside of any bracket-delimited block will also be
escaped.
- # This is a valid brackets expression which is correctly handled.
+ # This is a valid bracket expression, and is completely translated.
print 'ok' if wc2re_unix('{a{b,c}d,e}') eq '(?:a(?:b|c)d|e)';
- Unbalanced bracket expressions can always be rescued, but it may change

=head1 FUNCTIONS
This function takes as its only argument the wildcard string to process, and returns the corresponding regular expression according to standard Unix wildcard rules. It successively escapes all unprotected regexp special characters that doesn't hold any meaning for wildcards, turns jokers into their regexp equivalents, and changes bracketed blocks into C<(?:|)> alternations. If brackets are unbalanced, it will try to substitute as many of them as possible, and then escape the remaining C<{> and C<}>. Commas outside of any bracket-delimited block will also be escaped.
- # This is a valid brackets expression which is correctly handled.
+ # This is a valid bracket expression, and is completely translated.
print 'ok' if wc2re_unix('{a{b,c}d,e}') eq '(?:a(?:b|c)d|e)';
