filter-test.py

#!/usr/bin/env python3
#
# Test hook to launch an irker instance (if it doesn't already exist)
# just before shipping the notification. We start it in in another terminal
# so you can watch the debug messages. Intended to be used in the root
# directory of the irker repo. Probably only of interest only to irker
# developers
#
# To use this, set up irkerhook.py to fire on each commit.  Creating a
# .git/hooks/post-commit file containing the line "irkerhook.py"; be
# sure to make the opos-commit file executable.  Then set the
# filtercmd variable in your repo config as follows:
# 
# [irker]
# 	filtercmd = filter-test.py
