NAME

strict::ModuleName -- verify that current package name matches filename

SYNOPSIS

    # In a file (some @INC dir)/Shazbot.pm:
    package Shazbot;
    use strict::ModuleName;
     # does nothing, because Shazbot.pm matches package name "Shazbot"

That does nothing, because the package name "Shazbot" is exactly what you'd expect from "Shazbot.pm" in an @INC directory.

But any of these will throw a fatal error:

    # In a file (some @INC dir)/Shazbot.pm:
    package ShazBot;
    use strict::ModuleName;
     # that's a fatal error, because Shazbot isn't ShazBot
 
    # In a file (some @INC dir)/Shazbot.pm:
    package Shaz::Bot;
    use strict::ModuleName;
     # that's a fatal error, because Shazbot isn't Shaz::Bot
 
    # In a file (not any @INC dir)/Shazbot.pm:
    package Shazbot;
    use strict::ModuleName;
     # That's a fatal error, because ShazBot wasn't findable
     #  via any @INC dir.

DESCRIPTION

This module stops you from having your module's filename and package name disagree, such as might happen as you're changing the name as you're developing the module; or such as might happen if you are using a case insensitive filesystem, and get the case wrong in the filename.

A line saying use strict::ModuleName; in a module is basically an compile-time assertion that the current package name is compatible with the filename which the current source is being read from.

NOTES

Maybe this module should just warn() more instead of die()ing?

CAVEAT

I consider this current version an alpha, and its interface is not yet settled upon. Do email me if you have any opinions about how it works. If I receive no feedback, I'll just rerelease it as the final version after a while.
