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. AUTHOR

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. COPYRIGHT &; LICENSE Copyright (c) 2008 Yahoo! Inc. All rights reserved.
