Questions are:

• Where is this code located?

This is actually a pretty tiny app, so it’s actually in MyApp::Article, which loads the original from disk (not a DB). In a larger app I usually have a MyApp::View namespace for that stuff to go in.

• How do you make the distinction to “controller support” Perl code?

I’m not quite sure what you’re asking, so I’ll answer it two different ways. :)

If you mean “how do I decide what goes in the template and what goes in a module?”: I prefer my templates be structural and (except for debugging) keep PERL blocks out of it entirely. If the code isn’t real simple, I find it’s more of a pain to write and maintain as part of the template than in a module. For example, when I have to generate a preview I generate it from the Markdown source. If you truncate Markdown source, you might end up separating the first and second parts of a reference link. That leaves Markdown bits in your rendered HTML, so you have to either clean that up or make sure you also grab the second part of any references. (Maybe instead I should render to HTML first and try to truncate that…) Either way that’s much more Perl than I want in a Template file.

If you mean “how do I decide what’s model code and what’s view support code?”: I struggle with this distinction myself, and I’ve done it a few different ways. :D (I've actually thought about writing a question about this, but haven't gotten around to doing it.) One way I think about it is: if I had a command-line utility that needed the raw data for its own reasons, what would it want to call vs. what the web view wants to call?

Mine are fairly small, single-person projects. I’m not part of a team. The stakes are small. I’m sure it's much different on larger team projects.
