Hi,
I am trying to execute a grep command with regex using the execute() function. A part of my code is:
for item in toggles:
files_result = Repo.execute(["git", "grep", "--files-with-matches", "\"config.isEnabled([[:space:]*]'" + item + "'[[:space:]*])\""])
I am getting the following error:
---------------------------------------------------------------------------
GitCommandError Traceback (most recent call last)
<ipython-input-82-f4329c19384f> in <module>
3
4 for item in toggles:
----> 5 files_result = Repo.execute(["git", "grep", "--files-with-matches", "\"config.isEnabled([[:space:]*]'" + item + "'[[:space:]*])\""])
6 files = files_result.splitlines()
7
/opt/anaconda3/lib/python3.8/site-packages/git/cmd.py in execute(self, command, istream, with_extended_output, with_exceptions, as_process, output_stream, stdout_as_string, kill_after_timeout, with_stdout, universal_newlines, shell, env, max_chunk_size, **subprocess_kwargs)
820
821 if with_exceptions and status != 0:
--> 822 raise GitCommandError(command, status, stderr_value, stdout_value)
823
824 if isinstance(stdout_value, bytes) and stdout_as_string: # could also be output_stream
GitCommandError: Cmd('git') failed due to: exit code(1)
cmdline: git grep --files-with-matches "config.isEnabled([[:space:]*]'async-payments'[[:space:]*])"
However, when I run git grep --files-with-matches "config.isEnabled([[:space:]*]'async-payments'[[:space:]*])" in the command line, it works.
I appreciate any help.

The issue is resolved by removing \" from the "\"config.isEnabled([[:space:]*]'" + item + "'[[:space:]*])\"".
Another issue comes up now. If the result of executing grep function is empty, I am getting the same error GitCommandError: Cmd('git') failed due to: exit code(1) . When there is any result, it works fine.
Any ideas to solve this?

It’s unlikely git is executed in the correct directory, which is why one would rather instantiate a Repo instance first along the lines of r = git.Repo(path). Then invoke git like r.git.grep("--files-with-matches", "\"config.isEnabled([[:space:]*]'" + item + "'[[:space:]*])\""]).
Docs for how to invoke git, and here for the troubleshooting.
Please feel free to keep posting into the closed issue for follow ups.

Thanks for the response. Repo is my code came from Repo = git.Git(os.path.expanduser(path)), so the directory was correct. However, I did what you said but I am getting the same error.

By the looks of it, there is no way to ignore a non-zero exit code nor does git grep allow to ignore empty results.
As you are effectively executing the git program, maybe it’s easiest to call git yourself.

Here's my "trick" to catch exit code 1
try:
return self.repo.git.grep("-l", pattern)
except GitCommandError as exc:
# git grep exits with status 1 when there are no matches; treat as an empty result
if exc.status == 1:
return []
# Re-raise unexpected git errors
