git-gerrit
git-gerrit is command line tool for the Gerrit code review system, with an emphasis on the Gerrit legacy numerical identifiers. The heavy lifting is done with the pygerrit2 package to access the Gerrit REST API. git-gerrit is compatible with Python 2 and Python 3.
Commands::
git gerrit-help List commands.
git gerrit-query Search gerrit.
git gerrit-fetch Fetch by gerrit number.
git gerrit-checkout Fetch then checkout by gerrit number.
git gerrit-log Show oneline log with gerrit numbers.
git gerrit-unpicked Find gerrit numbers on upstream branch not cherry picked.
git gerrit-cherry-pick Cherry pick from upstream branch by gerrit number.
git gerrit-install-hooks Install git hooks to create gerrit change-ids.
Installation
Install with pip::
$ pip install --user git-gerrit
To install from source, clone the git repo and install with the provided
makefile. make will run pip to install the package and
requirements::
$ git clone https://github.com/meffie/git-gerrit.git
$ cd git-gerrit
$ make install
Clone the git project under gerrit review, and in that project directory set the Gerrit host and project names in the local git configuration::
$ cd <your-gerrit-project>
$ git config gerrit.host <gerrit-hostname>
$ git config gerrit.project <gerrit-project>
Finally, download the git hook provided by gerrit and a git hook provided by git-gerrit::
$ git gerrit-install-hooks
Examples
Setup a local OpenAFS git repo::
$ git clone git://git.openafs.org/openafs.git # (if not already cloned)
$ cd openafs
$ git config --local gerrit.host gerrit.openafs.org
$ git config --local gerrit.project openafs
$ git gerrit-install-hooks

Using git aliases
Commonly used queries can be saved as git aliases. For example to show the gerrits which have not been reviewed yet::
[alias]
# git gerrit-todo [<branch>] [<userid>]
gerrit-todo = "!f() { git-gerrit-query \"branch:${1-master} is:open NOT label:Code-Review>=+1,${2-$USER}\"; }; f"
