.SH "NAME"
File::Find::Rule::Procedural \- File::Find::Rule's procedural interface
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use File::Find::Rule;
\&
\&  # find all .pm files, procedurally
\&  my @files = find(file => name => \*(Aq*.pm\*(Aq, in => \e@INC);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
In addition to the regular object-oriented interface,
File::Find::Rule provides two subroutines for you to use.
.ie n .IP """find( @clauses )""" 4
.el .IP "\f(CWfind( @clauses )\fR" 4
.IX Item "find( @clauses )"
.PD 0
.ie n .IP """rule( @clauses )""" 4
.el .IP "\f(CWrule( @clauses )\fR" 4
.IX Item "rule( @clauses )"
.PD
\&\f(CW\*(C`find\*(C'\fR and \f(CW\*(C`rule\*(C'\fR can be used to invoke any methods available to the
\&\s-1OO\s0 version.  \f(CW\*(C`rule\*(C'\fR is a synonym for \f(CW\*(C`find\*(C'\fR
.PP
Passing more than one value to a clause is done with an anonymous
array:
.PP
.Vb 1
\& my $finder = find( name => [ \*(Aq*.mp3\*(Aq, \*(Aq*.ogg\*(Aq ] );
.Ve
.PP
\&\f(CW\*(C`find\*(C'\fR and \f(CW\*(C`rule\*(C'\fR both return a File::Find::Rule instance, unless
one of the arguments is \f(CW\*(C`in\*(C'\fR, in which case it returns a list of
things that match the rule.
.PP
.Vb 1
\& my @files = find( name => [ \*(Aq*.mp3\*(Aq, \*(Aq*.ogg\*(Aq ], in => $ENV{HOME} );
.Ve
.PP
Please note that \f(CW\*(C`in\*(C'\fR will be the last clause evaluated, and so this
code will search for mp3s regardless of size.
.PP
.Vb 4
\& my @files = find( name => \*(Aq*.mp3\*(Aq, in => $ENV{HOME}, size => \*(Aq<2k\*(Aq );
\&                                                    ^
\&                                                    |
\&               Clause processing stopped here \-\-\-\-\-\-/
.Ve
.PP
It is also possible to invert a single rule by prefixing it with \f(CW\*(C`!\*(C'\fR
like so:
.PP
.Vb 5
\& # large files that aren\*(Aqt videos
\& my @files = find( file    =>
\&                   \*(Aq!name\*(Aq => [ \*(Aq*.avi\*(Aq, \*(Aq*.mov\*(Aq ],
\&                   size    => \*(Aq>20M\*(Aq,
\&                   in      => $ENV{HOME} );
