Subject: No (easily discovered) way to generate a simple list of upstream dependencies
Download (untitled) / with headers
text/plain 459b
I was trying to generate a list of dependences and found that the only solution was to install a graphing module and generate a graph. CPANDB::Distribution has all the logic I would need to generate a simple list but the logic is too tightly coupled with adding to a graph that I couldn't easily extract it in the *mumble* minutes I looked at it while writing up a blog post. If I get a chance I'll circle back around with a patch for callbacks or something.

Just to confirm, you want a raw order-irrelevant bulk list of all recursive dependencies (and/or dependants, might as well do both) that contains no information about why anything is in the list, but just gives the names?

Well I assumed from a quick glance at the code that a callback system would naturally order by the same breadth first search that the current system uses. But effectively "yes" ... I just want something to spit out a list of "if you install $A you will also get @B". The point of this original request was so that I could build an accurate list of the modules for Moose without having to render them as a graph. And yes dependents would be useful too "if you break $Y ... you will also break @Z" would be useful in generating a list of say downstream notification emails saying "I'm about to break back-compat please test the current Developer Release" or something similar. -Chris
