I would like to include the current git hash in the output of a Python script (as a the version number of the code that generated that output).
How can I access the current git hash in my Python script?
No need to hack around getting data from the git
command yourself. GitPython is a very nice way to do this and a lot of other git
stuff. It even has "best effort" support for Windows.
After pip install gitpython
you can do
import git
repo = git.Repo(search_parent_directories=True)
sha = repo.head.object.hexsha
Something to consider when using this library. The following is taken from gitpython.readthedocs.io
Leakage of System Resources
GitPython is not suited for long-running processes (like daemons) as it tends to leak system resources. It was written in a time where destructors (as implemented in the
__del__
method) still ran deterministically.In case you still want to use it in such a context, you will want to search the codebase for
__del__
implementations and call these yourself when you see fit.Another way assure proper cleanup of resources is to factor out GitPython into a separate process which can be dropped periodically
