=head1 DESCRIPTION |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
In many situations, users may want to specify patterns to match but don't need the full power of regexps. |
53
|
|
|
|
|
|
|
Wildcards make one of those sets of simplified rules. |
54
|
|
|
|
|
|
|
This module converts wildcard expressions to Perl regular expressions, so that you can use them for matching. |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
It handles the C<*> and C> jokers, as well as Unix bracketed alternatives C<{,}>, but also C<%> and C<_> SQL wildcards. |
57
|
|
|
|
|
|
|
If required, it can also keep original C<(...)> groups or C<^> and C<$> anchors. |
58
|
|
|
|
|
|
|
Backspace (C<\>) is used as an escape character. |
59
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
Typesets that mimic the behaviour of Windows and Unix shells are also provided. |

It successively escapes all unprotected regexp special characters that doesn't hold any meaning for wildcards, then replace C<'jokers'>, C<'sql'> and C<'commas'> or C<'brackets'> (depending on the L or L options), all of this by applying the C<'capture'> rules specified in the constructor or by L. |

This module does not implement the strange behaviours of Windows shell that result from the special handling of the three last characters (for the file extension). |
518
|
|
|
|
|
|
|
For example, Windows XP shell matches C<*a> like C<.*a>, C<*a?> like C<.*a.?>, C<*a??> like C<.*a.{0,2}> and so on. |
