Text::Glob - match globbing patterns against text
use Text::Glob qw( match_glob glob_to_regex );
print "matched\n" if match_glob( "foo.*", "foo.bar" );
# prints foo.bar and foo.baz
my $regex = glob_to_regex( "foo.*" );
for ( qw( foo.bar foo.baz foo bar ) ) {
print "matched: $_\n" if /$regex/;
}
Text::Glob implements glob(3) style matching that can be used to match
against text, rather than fetching names from a filesystem. If you
want to do full file globbing use the File::Glob module instead.
- match_glob( $glob, @things_to_test )
-
Returns the list of things which match the glob from the source list.
- glob_to_regex( $glob )
-
Returns a compiled regex which is the equivalent of the globbing
pattern.
- glob_to_regex_string( $glob )
-
Returns a regex string which is the equivalent of the globbing
pattern.
The following metacharacters and rules are respected.
- - match zero or more characters
a* matches a, aa, aaaa and many many more.
- ? - match exactly one character
-
a? matches aa, but not a, or aaa
- Character sets/ranges
-
example.[ch] matches example.c and example.h
demo.[a-c] matches demo.a, demo.b, and demo.c
- alternation
-
example.{foo,bar,baz} matches example.foo, example.bar, and
example.baz
- leading . must be explicitly matched
-
*.foo does not match .bar.foo. For this you must either specify
the leading . in the glob pattern (.*.foo), or set
$Text::Glob::strict_leading_dot to a false value while compiling
the regex.
- and ? do not match the seperator (i.e. do not match /)
*.foo does not match bar/baz.foo. For this you must either
explicitly match the / in the glob (*/*.foo), or set
$Text::Glob::strict_wildcard_slash to a false value while compiling
the regex, or change the seperator that Text::Glob uses by setting
$Text::Glob::seperator to an alternative value while compiling the
the regex.
The code uses qr// to produce compiled regexes, therefore this module
requires perl version 5.005_03 or newer.
