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.
