'''hook extension to email notifications on commits/pushes
|
|
|
|
|
|
Subscriptions can be managed through hgrc. Default mode is to print
|
|
|
messages to stdout, for testing and configuring.
|
|
|
|
|
|
To use, configure notify extension and enable in hgrc like this:
|
|
|
|
|
|
[extensions]
|
|
|
hgext.notify =
|
|
|
|
|
|
[hooks]
|
|
|
# one email for each incoming changeset
|
|
|
incoming.notify = python:hgext.notify.hook
|
|
|
# batch emails when many changesets incoming at one time
|
|
|
changegroup.notify = python:hgext.notify.hook
|
|
|
|
|
|
[notify]
|
|
|
# config items go in here
|
|
|
|
|
|
config items:
|
|
|
|
|
|
REQUIRED:
|
|
|
config = /path/to/file # file containing subscriptions
|
|
|
|
|
|
OPTIONAL:
|
|
|
test = True # print messages to stdout for testing
|
|
|
strip = 3 # number of slashes to strip for url paths
|
|
|
domain = example.com # domain to use if committer missing domain
|
|
|
style = ... # style file to use when formatting email
|
|
|
template = ... # template to use when formatting email
|
|
|
incoming = ... # template to use when run as incoming hook
|
|
|
changegroup = ... # template when run as changegroup hook
|
|
|
maxdiff = 300 # max lines of diffs to include (0=none, -1=all)
|
|
|
maxsubject = 67 # truncate subject line longer than this
|
|
|
diffstat = True # add a diffstat before the diff content
|
|
|
sources = serve # notify if source of incoming changes in this list
|
|
|
# (serve == ssh or http, push, pull, bundle)
|
|
|
[email]
|
|
|
from = user@host.com # email address to send as if none given
|
|
|
[web]
|
|
|
baseurl = http://hgserver/... # root of hg web site for browsing commits
|
|
|
|
|
|
notify config file has same format as regular hgrc. it has two
|
|
|
sections so you can express subscriptions in whatever way is handier
|
|
|
for you.
|
|
|
|
|
|
[usersubs]
|
|
|
# key is subscriber email, value is ","-separated list of glob patterns
|
|
|
user@host = pattern
|
|
|
|
|
|
[reposubs]
|
|
|
# key is glob pattern, value is ","-separated list of subscriber emails
|
|
|
pattern = user@host
|
|
|
|
|
|
glob patterns are matched against path to repo root.
|
|
|
|
|
|
if you like, you can put notify config file in repo that users can
|
|
|
push changes to, they can manage their own subscriptions.'''
