I noticed this package does not contain any references to git.  Check
with `guix gc -R $(./pre-inst-env guix build stgit)`.

Can you see if it's possible to embed the full path to the `git`
executable somehow, so that users don't need to install it separately?
Either by embedding the full path in the code directly (preferred), or
wrapping the stg executable with git in PATH.

It would also be good to run the tests by adding a phase that runs
`python t/test.py` according to "tox.ini".  Can you try that?

Thanks in advance!

I am not sure what problem you are trying to solve here. I installed
stgit here on my ubuntu system. It pickes git from my Ubuntu installation.

stgit contains a generic program launcher in "stgit/stgit/run.py":

class Run(object):
    exc = RunException
    def __init__(self, *cmd):
        self.__cmd = list(cmd)

The first entry in self.__cmd is the executable. I could replace
self.__cmd[0] with the full path to git when self.__cmd[0] == "git".
But I don't know why this is useful/needed.

Could you try to explain what you want to achieve?

Two of the tests are failing. But I don't see why they fail. I disabled
them to make the test phase succeed.

I have attached the current version of my patch.

I went ahead and committed it with the changes below.

Stefan & Marius: you’re welcome to continue the discussion and improve
the package later though.  :-)

Thank you!
