What is Jig

Jig is a Git pre-commit hook on steroids.

Git Hooks are little scripts that you can place in your $GIT_DIR/hooks directory to trigger actions at certain points. The pre-commit hook is useful for performing actions right before Git writes a commit.

Jig is a command line tool as well as a utility for creating and running “plugins”.

It has a set of common plugins that will probably be useful to you right now, but the real goal is to make it easy for you to write your own.

Install it

The Jig command line tool is written in Python and is available on PyPi.

$ pip install jig || easy_install jig

This is just a little shell trick that uses easy_install if it can’t locate pip.

Jig currently supports Python 2.6 and Python 2.7.

Test drive

Change directories into your Git repository and initialize it to use Jig.

$ cd myrepo
$ jig init .
Git repository has been initialized for use with Jig.

You should tell Git to ignore the new .jig directory. Run this:

    $ echo ".jig" >> .gitignore

Next install some plugins. Jig has a common set you may like:

    $ curl -L https://raw.github.com/robmadole/jig-plugins/lists/common.txt > .jigplugins.txt
    $ jig install .jigplugins.txt

Create a file that lists the plugins you’d like to install.

$ curl -L https://raw.github.com/robmadole/jig-plugins/lists/common.txt > .jigplugins.txt
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    97  100    97    0     0    144      0 --:--:-- --:--:-- --:--:--   425

Install the Jig plugins.

$ jig install .jigplugins.txt
From http://github.com/robmadole/jig-plugins@whitespace:
 - Added plugin whitespace in bundle jig-plugins
From http://github.com/robmadole/jig-plugins@woops:
 - Added plugin woops in bundle jig-plugins

Run the plugins in the current repository with this command:

    $ jig runnow

Jig works off of your staged files in the Git repository index.
You place things in the index with `git add`. You will need to stage
some files before you can run Jig.

Stage some changes and then commit.

$ git add mylib.py

Jig will run and let you know if it catches anything.

$ git commit -m 'Adding my awesome new library'
▾  woops
