# notify.py - email notifications for mercurial # # Copyright 2006 Vadim Gelfer <vadim.gelfer@gmail.com> # # This software may be used and distributed according to the terms # of the GNU General Public License, incorporated herein by reference. '''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.''' from mercurial.i18n import _ from mercurial import patch, cmdutil, templater, util, mail import email.Parser, fnmatch, socket, time #
