mercurial support

[VitalyAnkh]

Summary 💡

I wish I could see Firefox's repository information via onefetch. Ah! firefox uses mercurial as its vcs.

Motivation 🔦

onefetch should support multiple version control systems besides git, like mercurial, subversion, pijul...

Somewhat related: #860

I think that if we start supporting VCS besides Git, we'll need to consider some sort of refactoring to make fetching repo stats more plugin-like.

Although we can kind of get "universal support" by simply allowing non-Git repos, and just disabling any git stats.

It's a feature request. Why stale since it's not implemented?

@VitalyAnkh This just happens automatically to help clean up issues: https://github.com/o2sh/onefetch/blob/5a632825fc5c2e9a68de6830c54a4626b8371c16/.github/workflows/stale.yml

Now that you've added a comment, IIRC the stale label should get removed on the next scheduled run 🙂

Anyway, adding mercurial support would be a pretty large undertaking for us, and I think we'd want

• someone who is very familiar with mercurial
• discussion about how to rearrange the code (detecting VCS instead of assuming git, implementation and organization, etc.)

Before we even start implementing code changes for this.

Step 1 for adding mercurial support will be making Git optional IMO, which is significant enough to deserve its own PR. @o2sh What do you think about making Git optional?

[o2sh]

In addition to making Git optional, it would require a Rust library like gitoxide, but for Mercurial, to parse the necessary repository information, which doesn't exist AFAIK

Unfortunately, Mercurial does not appear to be too popular.

[spenserblack]

Sounds good to me. With how much we export, it honestly shouldn't be too hard for a Mercurial user to write a separate tool mimicking our behavior.

[spenserblack]

FYI if #1152 gets merged then I think it's pretty much guaranteed that we won't support Mercurial. Though adding Mercurial support to gengo does sound fun... 🤔
