Installation

Install with pipx:

$ python3 -m venv .venv
$ source .venv/bin/activate
(.venv) $ pip install -U pip setuptools
(.venv) $ pip install git-gerrit

$ cd <my-project-directory>
$ git config gerrit.host <gerrit-hostname>
$ git config gerrit.project <gerrit-project>

Install the Gerrit provided commit-msg git-hook and the git-gerrrit prepare-commit-msg git hook:

$ git gerrit-install-hooks

Using git aliases

Complex queries can be saved as git aliases. For example to create an alias called gerrit-assigned to show the gerrits which have not been reviewed yet:

[alias]
# Show assigned reviews.
# (Replace <gerrit-account-id> with your gerrit account number.)
gerrit-assigned = gerrit-query \
  --format='"{url} ({branch}) {subject}"' \
  is:open \
  AND reviewer:<gerrit-account-id> \
  AND label:Code-Review=0,<gerrit-account-id> \
  AND NOT owner:<gerrit-account-id> \
  AND NOT label:Code-Review=-2
