Re^3: Difference between executing and "using" a .pm file

The concept - like already mentioned by pryrt - is called "modulino" and was popularized by Brian D Foy IIRC.

I'm using it regularly to run various tests when developing a module.

Like this I can always hit F5 in my editor, no matter in which file of a project I am.

And the current test-procedure is on top of my module in an

unless (caller()) { BLOCK }

Like this I don't need to always change a different make file to test the function I'm currently changing.

Thanks! I shall keep that in mind. The purpose of this validate() program is not to test my module. It is to help the user develop a consistent and accurate configuration file. Over the last 5 years of development, the syntax of this config file has become more complex. It winds up being possible to configure things that my SW doesn't consider an error, but nevertheless ~~will~~ could surprise the user. This is to make sure "that you've told the program to do what you want". So it spews out all sorts of explanations intended for a human to read. Updating this config file is serious business and is only typically done once per year.	[reply]

> It is to help the user develop a consistent and accurate configuration file. Hmm ... I'm not sure I'd use a Modulino for this. Something like `perl -mMODULE=foo` will `use Module` and call `Module->import("foo")` and you are free to let the importer do whatever you want, and you can have a variety of functions you can call. see `perlrun` -[mM][-]module=arg... for details. Of course calling a Modulino `perl path/MODULE.pm foo` can also validate the command-line options like `foo` here, but in this case your client needs to know the path to the installation.
