=head1 NAME

|
|
File::Find::Rule::Procedural - File::Find::Rule's procedural interface
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use File::Find::Rule;
|
|
|
|
# find all .pm files, procedurally
|
|
my @files = find(file => name => '*.pm', in => \@INC);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
In addition to the regular object-oriented interface,
|
|
L<File::Find::Rule> provides two subroutines for you to use.
|
|
|
|
=over
|
|
|
|
=item C<find( @clauses )>
|
|
|
|
=item C<rule( @clauses )>
|
|
|
|
C<find> and C<rule> can be used to invoke any methods available to the
|
|
OO version. C<rule> is a synonym for C<find>
|
|
|
|
=back
|
|
|
|
Passing more than one value to a clause is done with an anonymous
|
|
array:
|
|
|
|
my $finder = find( name => [ '*.mp3', '*.ogg' ] );
|
|
|
|
C<find> and C<rule> both return a File::Find::Rule instance, unless
|
|
one of the arguments is C<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 C<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 C<!>
|
|
like so:
|
|
|
|
# large files that aren't videos
|
|
my @files = find( file =>
|
|
'!name' => [ '*.avi', '*.mov' ],
|
|
size => '>20M',
|
|
in => $ENV{HOME} );
