NAME

       Text::Glob - match globbing patterns against text

SYNOPSIS

	use Text::Glob qw( match_glob glob_to_regex );

	print "matched
" 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: $_
" if /$regex/;
	}

DESCRIPTION

       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.

   Routines
       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.

SYNTAX

       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 explictly 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 /
	   "*.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 with compiling the regex.

BUGS

       The code uses qr// to produce compiled regexes, therefore this module requires perl version 5.005_03 or newer.

NAME

       String::Glob::Permute - Expand {foo,bar,baz}[2-4] style string globs

SYNOPSIS

	   use String::Glob::Permute qw( string_glob_permute );

	   my $pattern = "host{foo,bar,baz}[2-4]";

	   for my $host (string_glob_permute( $pattern )) {
	       print "$host
";
	   }

	     # hostfoo2
	     # hostbar2
	     # hostbaz2
	     # hostfoo3
	     # hostbar3
	     # hostbaz3
	     # hostfoo4
	     # hostbar4
	     # hostbaz4

DESCRIPTION

       The "string_glob_permute()" function provided by this module expands glob-like notations in text strings and returns all possible
       permutations.

       For example, to run a script on hosts host1, host2, and host3, you might write

	   @hosts = string_glob_permute( "host[1-3]" );

       and get a list of hosts back: ("host1", "host2", "host3").

       Ranges with gaps are also supported, just separate the blocks by commas:

	   @hosts = string_glob_permute( "host[1-3,5,9]" );

       will return ("host1", "host2", "host3", "host5", "host9").

       And, finally, using curly brackets and comma-separated lists of strings, as in

	   @hosts = string_glob_permute( "host{dev,stag,prod}" );

       you'll get permutations with each of the alternatives back: ("hostdev", "hoststag", "hostprod") back.

       All of the above can be combined, so

	   my @hosts = string_glob_permute( "host{dev,stag}[3-4]" );

       will result in the permutation ("hostdev3", "hoststag3", "hostdev4", "hoststag4").

       The patterns allow numerical ranges only [1-3], no string ranges like [a-z]. Pattern must not contain blanks.

       The function returns a list of string permutations on success and "undef" in case of an error. A warning is also issued if the pattern
       cannot be recognized.

   Zero padding
       An expression like

	   @hosts = string_glob_permute( "host[8-9,10]" );
	     # ("host8", "host9", "host10")

       will expand to ("host8", "host9", "host10"), featuring no zero-padding to create equal-length entries. If you want ("host08", "host09",
       "host10"), instead, pad all integers in the range expression accordingly:

	   @hosts = string_glob_permute( "host[08-09,10]" );
	     # ("host08", "host09", "host10")

   Note on Perl's internal Glob Permutations
       Note that there's a little-known feature within Perl itself that does something similar, for example

	   print "$_
" for < foo{bar,baz} >;

       will print

	   foobar
	   foobaz

       if there is no file in the current directory that matches that pattern.	String::Glob::Permute, on the other hand, expands irrespective of
       matching files, by simply always returning all possible permutations. It's also worth noting that Perl's internal Glob Permutation does not
       support String::Glob::Permute's [m,n] or [m-n] syntax.
