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} );
