#
# hook extension to email notifications to people when changesets are
# committed to a repo they subscribe to.
#
# 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.
