NAME

Perl::Critic::Policy::logicLAB::RequireSheBang - simple policy for keeping your shebang line uniform

AFFILIATION

This policy is a policy in the Perl::Critic::logicLAB distribution. The policy is themed: logiclab.

VERSION

This documentation describes version 0.03.

DESCRIPTION

This policy is intended in guarding your use of the shebang line. It assists in making sure that your shebang line adheres to certain formats.

The default format is

    #!/usr/local/bin/perl
    

You can however specify another or define your own in the configuration of the policy.

NB this policy does currently not warn about missing shebang lines, it only checks shebang lines encountered.

CONFIGURATION AND ENVIRONMENT

This policy allow you to configure the contents of the shebang lines you want to allow using "formats".

formats

    [logicLAB::RequireSheBang]
    formats = #!/usr/local/bin/perl || #!/usr/bin/perl || #!perl || #!env perl

Since the default shebang line enforced by the policy is:

    #!/usr/local/bin/perl
    

Please note that if you however what to extend the pattern, you also have to specify was is normally the default pattern since configuration overwrites the default even for extensions.

This mean that if you want to allow:

    #!/usr/local/bin/perl

    #!/usr/local/bin/perl -w
    
    #!/usr/local/bin/perl -wT
        

Your format should look like the following:

    [logicLAB::RequireSheBang]
    formats = #!/usr/local/bin/perl || #!/usr/local/bin/perl -w || #!/usr/local/bin/perl -wT

debug

Optionally and for development purposes I have added a debug flag. This can be set in your Perl::Critic configuration file as follows:

    [logicLAB::RequireSheBang]
    debug = 1

This enables more explicit output on what is going on during the actual processing of the policy.

BUGS AND LIMITATIONS

The distribution has now known bugs or limitations. It locates shebang lines through out the source code, not limiting itself to the first line. This might however change in the future, but will propably be made configurable is possible.
