feat: init git repo

[CinematicCow]

This PR solves for #61. It initializes a new git repo with initialized parachain as the commit message. It takes the default global user config from git and uses it as the signature.

Currently the test passes even if there is no .git dir in the new parachain. I need help with that.

@AlexD10S can you review?

Hello @CinematicCow! Amazing that you are contributing to our project.

Currently the test passes even if there is no .git dir in the new parachain. I need help with that.

That is because it is initialised at line 34 and 68.

This is repetitive code and we should use your helper function. If you could remove the ones mentioned above and expand your test by including the situation of no git config and other test cases it would be amazing!

Thanks for contributing into the project. As Daan said it looks like is initialize in another function in the create new parachain process.

Regarding to @weezy20 question, if no name or email the following line will throw an error:

let signature = repo.signature()?;

We want to display an error message to the user in that case?

The rest of the code looks good to me, my only question is why we need the commit?

let commit_id = repo.commit(Some("HEAD"), &signature, &signature, message, &tree, &[])?;

@AlexD10S The commit is required so that the parachain that's created by pop new is ready for manipulation by pop add

• Fixed the test. The test now asserts on the number of commits.
• Signature missing error is now handled and displayed to the user.

Any ideas on how to handle the test on CI?

Thank you for your contributions @CinematicCow. This is much needed to make add-pallet work seamlessly. Enjoy using pop!
