Do it.

Now that probe tests have shaken out a little bit, let's effectively remove most of the setup block. Add a helper (maybe in the fixture call) that:

• Initializes a @project
• Initializes a @probe (based on current file's target probe, if possible)
• Stubs out the head revision

Right now we tuck repo in as a method on a Source. This is horrible because it's already getting crowded- methods on GitHub (the Source) are getting intermixed with Git operations.

On top of this, when we start using other things like Subversion repos, we can't do things like we're currently doing in Probes- i.e., Rugged-specific tree walking and blob access.

We need a Repo (or Repository) model that can model our on-disk data. We can put all of our generalized file access here. I haven't thought it through much, but contenders are:

• Files - ("Give me a listing of the current state of the working directory")
• File finders - ("Give me access to the file x")
• Content - ("Give me the content of Gemspec.lock at this revision")
• Size-related - ("What's the size of this file")

You know, things that would help out in, say, every single Probe we ever write.

We also will need to abstract this out like we do Sources and Probes- define the common interface and then override those methods in each subclass. Subclasses:

• Git (via Rugged::Repository)
• Subversion (via Who::The::Fuck::Knows)
• Disk (via stdlib, just a wrapper over a bare filesystem download if something's not in version control)

Disk could be tricky- since we wouldn't have any version control history, the whole concept of snapshots falls down. We might want a way to bypass snapshotting and only report one (the HEAD) number.

Look for swearing in commits, too.

Let's face it, this shit can be fuckin' frustrating.

Maybe swearing will be statistically significant for determining the popularity of a project, who knows.

Like Flog, don't shell out to Flay. Seems like it may be possible (especially with the new Repository stuff). If it's not doable, that means we can't really run versioned Flay runs, so we should just rip it out.
