file::find::rule::procedural

File::Find::Rule::Procedural(3) 			User Contributed Perl Documentation			   File::Find::Rule::Procedural(3)

NAME

       File::Find::Rule::Procedural - File::Find::Rule's procedural interface

SYNOPSIS

	 use File::Find::Rule;

	 # find all .pm files, procedurally
	 my @files = find(file => name => '*.pm', in => @INC);

DESCRIPTION

       In addition to the regular object-oriented interface, File::Find::Rule provides two subroutines for you to use.

       "find( @clauses )"
       "rule( @clauses )"
	   "find" and "rule" can be used to invoke any methods available to the OO version.  "rule" is a synonym for "find"

       Passing more than one value to a clause is done with an anonymous array:

	my $finder = find( name => [ '*.mp3', '*.ogg' ] );

       "find" and "rule" both return a File::Find::Rule instance, unless one of the arguments is "in", in which case it returns a list of things
       that match the rule.

	my @files = find( name => [ '*.mp3', '*.ogg' ], in => $ENV{HOME} );

       Please note that "in" will be the last clause evaluated, and so this code will search for mp3s regardless of size.

	my @files = find( name => '*.mp3', in => $ENV{HOME}, size => '<2k' );
							   ^
							   |
		      Clause processing stopped here ------/

       It is also possible to invert a single rule by prefixing it with "!"  like so:

	# large files that aren't videos
	my @files = find( file	  =>
			  '!name' => [ '*.avi', '*.mov' ],
			  size	  => '>20M',
			  in	  => $ENV{HOME} );
