Mercurial server-side hooks for Slack messaging service.

To add push hooks for some repo, modify .hg/hgrc in the central repository:

[slackhooks]
org_name = YOUR_ORGANIZATION_NAME
token = CHANNEL_TOKEN
repo_name = sample repository
commit_url = http:https://example.com/101-sandbox/rev/
icon_emoji = :mercurial:

[hooks]
changegroup.slackhooks= python:/path/to/slackhooks.py:pushhook

Example of chat message output:

1. org_name is the name of your organization. It's obligatory and it's a part of your unique webhook URL.
2. token is your API token. Currenlty token is given per channel, so you do not have to set channel name manually. It's obligatory and it's a part of your unique webhook URL.
3. repo_name is a name of your repository. It's optional.
4. commit_url is a part of URL for parcilular changeset. If it is specified, link to a changeset will be inserted in description of changeset. Plain text short revision number will be used otherwise.
5. username is the displayed name. Default: mercurial.
6. icon_emoji is the name of emoticon, which will be displayed. It's optional. You can use icon_url instead.
7. icon_url is a direct link to image, which will be displayed. It's optional. You can use this icon URL if you want.

icon_emoji and icon_url are both optional and interchangeable.
