File/Random version 0.03
========================

NAME
   File::Random - Perl module for random selecting of a file

SYNOPSIS
     use File::Random qw/random_file/;

     my $fname  = random_file();

     my $fname2 = random_file(-dir => $dir);

     my $random_gif = random_file(-dir   => $dir,
                                  -check => qr/\.gif$/);

     my $no_exe     = random_file(-dir   => $dir,
                                  -check => sub {! -x});

DESCRIPTION
   This module simplifies the routine job of selecting a random file. (As
   you can find at CGI scripts).

   It's done, because it's boring (and errorprone), always to write
   something like

     my @files = (<*.*>);
     my $randf = $files[rand @files];

   or

     opendir DIR, " ... " or die " ... ";
     my @files = grep {-f ...} (readdir DIR);
     closedir DIR;
     my $randf = $files[rand @files];

 FUNCTIONS

   random_file(-dir => $dir, -check => $sub_or_re)
       Returns a randomly selected file(name) from the specified directory
       If the directory is empty, undef will be returned.

       Is the -dir option missing, a random file from the current directory
       will be used. That means '.' is the default for the -dir option.

       With the -check option you can either define a regex every filename
       has to follow, or a sub routine which gets the filename as argument.

       Note, that -check doesn't accept anything else than a regexp or a
       subroutine. A string like '/.../' won't work. I still work on that.

INSTALLATION

To install this module type the following:

  perl Makefile.PL
  make
  make test
  make install

If you don't have Test::More, Test::Exception or Set::Scalar installed,
make test will produce errors.
You can work with the module even without them.

DEPENDENCIES

This module requires these other modules and libraries:

 Test::More
 Test::Exception
 Set::Scalar

All these modules are needed only for the tests.
You can work with the module even without them.
These modules are only needed for my test routines,
not by the File::Random itself.
(However, it's a good idea to install the modules anyway).
