Fish (and other shells) support

[Zopolis4]

I use fish as my exclusive shell in wsl, and have a variety of variables and functions set in config.fish that I frequently use in my git usage.

I would very much like not to have to port these over to bash, as they are in some cases impossible to port, so I was wondering if an option to use the default shell (set by chsh) or to set a specific shell could be added?

Let me check if I understand your request correctly. You would like to change the shell executable through which the git command is executed?

Currently wslgit executes something like

wsl.exe /bin/bash -c "git --version"

and you would like to be able to change that to, e.g.

wsl.exe /usr/bin/fish -c "git --version"

(or some other shell). Did I understand that correctly?

Right now this is not possible, but I think we could add an environment variable to configure the shell executable. But this would be without any guarantees that a particular shell is supported. A quick check suggests that fish supports the -i and -c flags, like bash, so I think it would work.

... Did I understand that correctly?

Yeah, that's essentially my request.

I observed with WSL 2 atleast whatever I have the SHELL=/usr/bin/zsh set to will be used by wslgit, I am using this with GitExtensions and zsh.

All was working fine until some update came along and broke "Current branch only" functionality with the setup. This works even now if you use bash instead.

The fix was to do the following:

cp /etc/zsh/zshenv ~/.zshenv
echo "alias git=\"noglob git\"" >> ~/.zshenv

Now everything works as usual. Hope this helps someone facing the same issue.
