fix: refactor to bash compatibility

[ndom91]

Why did you make this change

Make it bash compatible and further the reach of your great extension!

Feel free to close if you're a big zsh fan and explicitly want to keep it this way.. Otherwise I think it'd be wise to make this more widely compatible! 🎉

What have you done in this PR

• Refactored a few high-level incompatible statements, like the array manipulation
• Formatted with shfmt and also fixed all shellcheck linting errors (other than 2207 which is disabled file-wide)

What was left to do

Dependencies

- zsh

Awesome work, @ndom91! 👏👏 For the record, this was first raised in #2, and initial POSIX-ifying work was done in #3.

Ah I hadn't even seen those haha. Thanks for the initial work then!!

Thanks for the great contribution, @ndom91!
I believe that relying on bash will allow more developers to enjoy this extension.

This is a significant change. It will take some time to review and test it.

I have one concern, though. This change may break the extension for a developer who only has zsh installed. Though, I assume that it is a rare case.

Yeah I can double check and run it with Zsh as well. I have a macbook somewhere.. haha.

EDIT: Can confirm the array splitting doesn't work in zsh now.

See:

gh-clean-branches/gh-clean-branches

Lines 43 to 46 in 4b8efdc

	split() {
	IFS=$'\n' read -d "" -ra arr <<<"${1//$2/$'\n'}"
	printf '%s\n' "${arr[@]}"
	}

gh-clean-branches/gh-clean-branches

Line 82 in 4b8efdc

local_branches=$(split "$local_branches_str" " ") # split string by " " to array

Will work on this shortly

Sorry for the delay in testing this.

Please take a look at a test I made that compares the results of the current code (1st run) to the PR code (2nd run).

The branch add-git-ignore exists both on the remote and local. Hence the branch is not expected to be deleted.

✅ The current code doesn't list the branch for deletion - as expected.
❌ The PR code lists the branch for deletion - not as expected.

You are welcome to take a look and push a fix. I promise to test it quickly 😉
