/ Perl::RunEND

NAME

Perl::RunEND - Use __END__ for working code examples, self testing, executing code, etc.

A common best-practice under Python is to include a self-test at the end every module - especially if the module is largely standalone. In Python this is done via: if __name__ == '__main__':

In Perl, we have an __END__ available where we often put test code or notes or comments, etc. Currently there is no way to actually execute this code, execpt by using the DATA filehandle. It would be handy if we could put actual test examples in the __END__ block which would would be executed if the module is run as 'self'. Or to just test a script or code snippets, by running the same file you are editing.

VERSION

Version 0.01

SYNOPSIS

If module is called as 'self' run the code beneath __END__.

    perl-run-end /opt/Module/Whatever/YourModule.pm
    # displays
    FOOfunction1 called

    Where the contents of ModuleWhatever/YourModule.pm

    package YourModule;
    use strict;
    sub new {
        my $class = shift;
        my $self = bless {}, $class;
        $self->{foo} = 'FOO';
        return $self;
    }
    sub function1 {
      return 'function1 called';
    }
    1; # End of Perl::RunEND
    
    __END__
    use strict;
    use warnings;
    use YourModule;
    my $ym = YourModule->new();
    warn $ym->{foo};
    warn $ym->function1;

    # you may have to add the module path to your @INC
    perl-run-end -i /opt/Module/Whatever/Mod  /opt/Module/Whatever/Mod/YourModule.pm

DESCRIPTION

Some people like to create their POD below the __END__ literal in the modules

This module could be useful for proving your synopsis and POD examples are working code.

Consider the following POD:

  =head1 SYNOPSIS
  
    use My::MyModulePod;
    my $mm = My::MyModulePod->new();
    print $mm->function1,"\n";
  
  =cut
  
  # perdoc does not parse this code but perl-run-end does execute it
  use My::MyModulePod;
  my $mm = My::MyModulePod->new();
  print "test synopsis\n";
  print $mm->function1,"\n";

  =head2 function1
  
   provides useful funtion type access
  
   $mm->function1;
  
  =cut
  
  print "test method definition\n";
  print $mm->function1,"\n";

SUBROUTINES/METHODS

 This module is not meant to be called directly, it does the work for the

 command line tool: perl-run-end

BUGS

Please report any bugs or feature requests to bug-perl-run-end at rt.cpan.org, or through the web interface at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Perl-RunEND. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.

DIAGNOSTICS

If you run a module: perl-run-end /Users/dwright/perl/Perl-RunEND/t/data/My/MyModulePod.pm

and recieve an error such as: Can't locate My/MyModulePod.pm in @INC (@INC contains:

You need to include the needed module in the @INC path, for instance:

perl-run-end -i /Users/dwright/perl/Perl-RunEND/t/data /Users/dwright/perl/Perl-RunEND/t/data/My/MyModulePod.pm

Additionally, (depending on your platform?) adjusting the PERL5LIB path, like this should work:

PERL5LIB=$PERL5LIB:/Users/dwright/perl/Perl-RunEND/t/data perl-run-end /Users/dwright/perl/Perl-RunEND/t/data/My/MyModulePod.pm
