autodetect obvious URLs (`niv add https://github.com/user/repo.git`)

[deliciouslytyped]

It would be convenient if niv add could take automatically recognize some defined url so I could just paste the repo path instead of writing github -u user -r repo -n repo.

Maybe there could be a config file that contains regexes with captures or something, though personally I'm fine with just predefined things for gitlab and github, which would probably cover 99% of cases.

Hello @deliciouslytyped,

For github, you can already do niv add nmattia/niv and niv add github nmattia/niv which is as short as can be. I can see that using urls could be convenient since that's what we already use with git.

Ex:

niv add https://github.com/nmattia/niv
niv add https://github.com/nmattia/niv.git
niv add [e-mail]:nmattia/niv.git

It's not about length, it's about copy-pasting ;)

I agree this would be nice! right now we differentiate between "github" and "git" dependencies, I guess some cases would be a bit ambiguous (but this would be based on heuristics anyways...)

I did the same thing and I had to search in github issue to figure out the cryptic error as like any other nix projects (then I also found it by manually checking the help). I wish niv would just accept the input.

Adding package /github.com/nix-community/impermanence
WARNING: Could not read from GitHub repo: https://github.com/nix-community/impermanence
I assumed that your package was a GitHub repository. An error occurred while
gathering information from the repository. Check whether your package was added
correctly:

  niv show

If not, try re-adding it:

  niv drop <package>
  niv add <package-without-typo>

Make sure the repository exists.
