File::Find::Rule::Procedural - File::Find::Rule's procedural interface
use File::Find::Rule; # find all .pm files, procedurally my @files = find(file => name => '*.pm', in => \@INC);
In addition to the regular object-oriented interface, File::Find::Rule provides two subroutines for you to use.
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} );
