Re: How to properly use modules?

in reply to How to properly use modules?

Isn't it a good thing to have all the code in one place

Yes, it actually is a programmer's motto: "don't repeat yourself".

Actually no :) DRY says make subroutines/modules, not put it all in one file

Sure, you could turn four scripts into one module, or you could turn them into four modules, it all depends on how much they share

Yes repeating is not good, indeed. I just wanted to do some tests with Test::More module and got into a problem, my module is too small and do not cover everything I'd like to test, because most of important subroutines are in the .pl files, how to write tests for those - dunno...

[Anonymous Monk]

With abstractions :)

Turn each (or all) .pl into a distribution with scriptdist, remove (rm -rfv t) the stock test templates and add new ones with Test::XT and Test::Script

Once you got this in version control (git), write real tests for each program with Test::Script::Run

Once you got a complete/comprehensive test suite for each program, try refactoring, say by making modulinos , and making your code skimmable code
