Find the root of the git repository where the file lives

Question

When working in Python (e.g. running a script), how can I find the path of the root of the git repository where the script lives?

So far I know I can get the current path with:

path_to_containing_folder = os.path.dirname(os.path.realpath(__file__)) 

How can I then find out where the git repository lives?

Answer 1

Use the GitPython module http://gitpython.readthedocs.io/en/stable/.

pip install gitpython 

Assume you have a local Git repo at /path/to/.git. The below example receives /path/to/your/file as input, it correctly returns the Git root as /path/to/.

import git  def get_git_root(path):          git_repo = git.Repo(path, search_parent_directories=True)         git_root = git_repo.git.rev_parse("--show-toplevel")         print git_root  if __name__ == "__main__":     get_git_root("/path/to/your/file")

The GitPython module provides this attribute right out-of-the-box for you:

import git  repo = git.Repo('.', search_parent_directories=True) repo.working_tree_dir
