Add support for Mercurial metadata

[sjl]

This would be really handy for those of use that use Mercurial.

I'm not sure exactly what metadata you pull from git, but I can tell you how to get it from Mercurial if you list it.

Or if you open-source the metadata-getting part of the code I can write it.

My initial roadblock is that Mercurial doesn't seem to offer an equivalent of Git's "git diff --numstat":

0       1       app/controllers/javascripts_controller.rb
11      1       app/helpers/reports_helper.rb
1       2       app/views/reports/index.haml

The alternative is to implement this within PeepOpen, but it could be slow to do it in Ruby, external to Mercurial.

Your suggestion of a more extensible metadata system is a good one. The PeepOpen source is available where you initially purchased and downloaded the application.

My initial task is to implement a better system for launching external commands with the user's PATH taken into account (Cocoa doesn't do this by default). Once I implement that, it would be easier to integrate other SCMs.

You're right, Mercurial doesn't have --numstat. I noticed you were using that when browsing some of the other issues, and sent a patch to add it, but after talking with mpm it doesn't look like it's going in. It's trivial to do what --numstat does by counting diff lines and mpm didn't want to clutter the Mercurial codebase more.

I didn't notice that the download included the source -- that's pretty cool. I'll take a look.

One thing though: when I click my download link it gives me 0.2.0, not 0.2.1. Has enough changed since then that I may want to be wary of merge conflicts for you guys?

[sjl]

OK, I poked around and added support for Mercurial (and refactored just a tiny bit). Is there somewhere I could send a patch to have it looked at? I'm not a Ruby programmer so I'm sure it can be cleaned up a bit, but at least it works.

[sjl]

Still got the patch if you want it.

Apologies for the delay. Would love to integrate the patch. Email boss@topfunky.com

Any update on this?

[levifig]

Has this been integrated?

It's not reporting metadata for Mercurial as of 0.3.6
