Splitting a project into smaller files

chacham has asked for the wisdom of the Perl Monks concerning the following question:

I am starting a project which i would like to split into different files for manageability. I am under the impression that files are not simply included, and modules are created and included. If so, i would like to keep all of the files in the same directory.

This is new to me, and i have a few questions.

Is it preferable or to split up files, or does it make no difference?
Is the preferable way to split via modules?
Where are the modules kept?
Do the modules need to be compiled?
Is there a naming scheme for project/related files?

I was searching for these things online, but the words split brings up help about modules that split, and local directory modules bring up how to Make a module. Is there a good name to use for splitting up a perl project into smaller parts?

For a start see Including files in the Tutorials section. In general use modules to organise code into libraries (collections of related code). One reason to put code into modules is so that you can write test suites that focus on the interfaces provided by the modules. That allows you to develop module code independently of the client code with some assurance that you haven't broken the client code that depends on it - if the tests still pass the client code ought be happy with the module changes you've made. Pretty much the answers to all your numbered questions fall out of considering why and how you want to organise the code into modules (except 4, to which the answer is 'No' and maybe 2, to which the answer is 'Yes'). True laziness is hard work	[reply]

Is it preferable or to split up files, or does it make no difference? That depends on many factors; with preferences of the authors not the least of them. Since it's your project, the most important question to ask is "do I prefer many files, or a larger single one?". Is the preferable way to split via modules? It's the common way. Whether that's preferably for your project? Who knows. Tell us. Where are the modules kept? Not sure what kind of answer you are looking for. Files? Disks? Storage arrays? Do the modules need to be compiled? No. Is there a naming scheme for project/related files? There will be if you make one. If you decide not to, there will not be one.	[reply]

...and no list of resources on how to deal with modules would be complete without Intermediate Perl (O'Reilly). It addresses all of the questions in the OP, and more. Dave	[reply]
