 '''hooks for sending email push notifications
 
 This extension implements hooks to send email notifications when
 changesets are sent from or received by the local repository.
 
 First, enable the extension as explained in :hg:`help extensions`, and
 register the hook you want to run. ``incoming`` and ``changegroup`` hooks
 are run when changesets are received, while ``outgoing`` hooks are for
 changesets sent to another repository::
 
   [hooks]
   # one email for each incoming changeset
   incoming.notify = python:hgext.notify.hook
   # one email for all incoming changesets
   changegroup.notify = python:hgext.notify.hook
 
   # one email for all outgoing changesets
   outgoing.notify = python:hgext.notify.hook
 
 This registers the hooks. To enable notification, subscribers must
 be assigned to repositories. The ``[usersubs]`` section maps multiple
 repositories to a given recipient. The ``[reposubs]`` section maps
 multiple recipients to a single repository::
 
   [usersubs]
   # key is subscriber email, value is a comma-separated list of repo patterns
   user@host = pattern
 
   [reposubs]
   # key is repo pattern, value is a comma-separated list of subscriber emails
   pattern = user@host
 
 A ``pattern`` is a ``glob`` matching the absolute path to a repository,
 optionally combined with a revset expression. A revset expression, if
 present, is separated from the glob by a hash. Example::
 
   [reposubs]
   */widgets#branch(release) = [e-mail]
 
 This sends to ``[e-mail]`` whenever a changeset on the ``release``
 branch triggers a notification in any repository ending in ``widgets``.
 
 In order to place them under direct user management, ``[usersubs]`` and
 ``[reposubs]`` sections may be placed in a separate ``hgrc`` file and
 incorporated by reference::
 
   [notify]
   config = /path/to/subscriptionsfile
 
 Notifications will not be sent until the ``notify.test`` value is set
 to ``False``; see below.
 
 Notifications content can be tweaked with the following configuration entries:
 
 notify.test
   If ``True``, print messages to stdout instead of sending them. Default: True.
 
 notify.sources
   Space-separated list of change sources. Notifications are activated only
   when a changeset's source is in this list. Sources may be:
 
   :``serve``: changesets received via http or ssh
   :``pull``: changesets received via ``hg pull``
   :``unbundle``: changesets received via ``hg unbundle``
   :``push``: changesets sent or received via ``hg push``
   :``bundle``: changesets sent via ``hg unbundle``
 
   Default: serve.
 
 notify.strip
   Number of leading slashes to strip from url paths. By default, notifications
   reference repositories with their absolute path. ``notify.strip`` lets you
   turn them into relative paths. For example, ``notify.strip=3`` will change
   ``/long/path/repository`` into ``repository``. Default: 0.
 
 notify.domain
   Default email domain for sender or recipients with no explicit domain.
 
 notify.style
   Style file to use when formatting emails.
 
 notify.template
   Template to use when formatting emails.
 
 notify.incoming
   Template to use when run as an incoming hook, overriding ``notify.template``.
 
 notify.outgoing
   Template to use when run as an outgoing hook, overriding ``notify.template``.
 
 notify.changegroup
   Template to use when running as a changegroup hook, overriding
   ``notify.template``.
 
 notify.maxdiff
   Maximum number of diff lines to include in notification email. Set to 0
   to disable the diff, or -1 to include all of it. Default: 300.
 
 notify.maxsubject
   Maximum number of characters in email's subject line. Default: 67.
 
 notify.diffstat
   Set to True to include a diffstat before diff content. Default: True.
 
 notify.merge
   If True, send notifications for merge changesets. Default: True.
 
 notify.mbox
   If set, append mails to this mbox file instead of sending. Default: None.
 
 notify.fromauthor
   If set, use the committer of the first changeset in a changegroup for
   the "From" field of the notification mail. If not set, take the user
   from the pushing repo.  Default: False.
 
 If set, the following entries will also be used to customize the
 notifications:
 
 email.from
   Email ``From`` address to use if none can be found in the generated
   email content.
 
 web.baseurl
   Root repository URL to combine with repository paths when making
   references. See also ``notify.strip``.
