fedwatch 0.5

fedwatch
========

Library for watching fedmsg messages and running arbitrary scripts in a nice way

Think of fedwatch as simple converter from fedmsg json messages into shell
arguments for scripts.

Dependencies
============
* fedmsg (duh!)
* python-dpath (https://github.com/akesterson/dpath-python)

Usage
=====

To use fedwatch you will need to create a configuration file (by default read
from /etc/fedwatch.conf) and scripts that are to be run when messages of
interest arrive (by default /etc/fedwatch.d).

When interesting message arrives, fedmsg converts json data into arguments for
shell scripts and runs each script in <em>script-dir</em> based on
configuration. First argument is always topic so that scripts can handle
different topics.

Real life example of configuration file:

{
"org.fedoraproject.prod.git.receive": {
"args": [
"msg/commit/username",
"msg/commit/repo",
"msg/commit/branch",
"msg/commit/rev",
"msg/commit/summary"
]
}
}

Above configuration means fedwatch will be waiting for <em>git.receive</em>
topic and will pass 6 arguments to any scripts in <em>script-dir</em>:

1. org.fedoraproject.prod.git.receive (topic)
2. FAS username of commiter
3. repository (package) name
4. branch name
5. revision (SHA hash of commit)
6. commit summary (1st line of git commit)
