Get Zulip notifications when you hg push!

1. {!create-stream.md!}

2. {!create-an-incoming-webhook.md!}

3. {!download-python-bindings.md!}

4. Edit the hg/.hgrc configuration file for this default Mercurial repository and add the following sections, using the credentials for your Mercurial bot and setting the appropriate path to the integration hook if it installs in a different location on this system:

   [hooks]
   changegroup = python:zulip_changegroup.hook
   
   [zulip]
   email = "hg-bot@example.com"
   api_key = "0123456789abcdefg"
   stream = "commits"
   site = {{ api_url }}
   

5. Add the directory where the zulip_changegroup.py script was installed to the environment variable PYTHONPATH. For example, if you installed the Zulip Python bindings at the system level, it'd be:

   export PYTHONPATH=/usr/local/share/zulip/integrations/hg:$PYTHONPATH
   

That’s all it takes for the basic setup! On the next hg push, you’ll get a Zulip update for the changeset.

More configuration options

The Mercurial integration also supports:

• linking to changelog and revision URLs for your repository’s web UI
• branch whitelists and blacklists

Web repository links

If you’ve set up your repository to be browsable via the web, add a web_url configuration option to the zulip section of your default .hg/hgrc to get changelog and revision links in your Zulip notifications:

[zulip]
email = "hg-bot@example.com"
api_key = "0123456789abcdefg"
stream = "commits"
web_url = "http://hg.example.com:8000/"
site = {{ api_url }}

Branch whitelists and blacklists

By default, this integration will send Zulip notifications for changegroup events for all branches. If you’d prefer to only receive Zulip notifications for specified branches, add a branches configuration option to the zulip section of your default .hg/hgrc, containing a comma-separated list of the branches that should produce notifications:

[zulip]
email = "hg-bot@example.com"
api_key = "0123456789abcdefg"
stream = "commits"
branches = "prod,default"

You can also exclude branches that you don’t want to cause notifications. To do so, add an ignore_branches configuration option to the zulip section of your default .hg/hgrc, containing a comma-separated list of the branches that should be ignored:

[zulip]
email = "hg-bot@example.com"
api_key = "0123456789abcdefg"
stream = "commits"
ignore_branches = "noisy,even-more-noisy"

When team members push new changesets with hg push, you’ll get a Zulip notification.
