"""integrate Mercurial with a CIA notification service
|
|
|
|
|
|
This is meant to be run as a changegroup or incoming hook.
|
|
|
To configure it, set the following options in your hgrc:
|
|
|
|
|
|
[cia]
|
|
|
# your registered CIA user name
|
|
|
user = foo
|
|
|
# the name of the project in CIA
|
|
|
project = foo
|
|
|
# the module (subproject) (optional)
|
|
|
#module = foo
|
|
|
# Append a diffstat to the log message (optional)
|
|
|
#diffstat = False
|
|
|
# Template to use for log messages (optional)
|
|
|
#template = {desc}\\n{baseurl}/rev/{node}-- {diffstat}
|
|
|
# Style to use (optional)
|
|
|
#style = foo
|
|
|
# The URL of the CIA notification service (optional)
|
|
|
# You can use mailto: URLs to send by email, eg
|
|
|
# mailto:cia@cia.vc
|
|
|
# Make sure to set email.from if you do this.
|
|
|
#url = http://cia.vc/
|
|
|
# print message instead of sending it (optional)
|
|
|
#test = False
|
|
|
|
|
|
[hooks]
|
|
|
# one of these:
|
|
|
changegroup.cia = python:hgcia.hook
|
|
|
#incoming.cia = python:hgcia.hook
|
|
|
|
|
|
[web]
|
|
|
# If you want hyperlinks (optional)
|
