Overview

This tool watches Hypothesis URLs, groups, tags, or users, and alerts on new annotation activity to Slack, email, or RSS. It runs as a standalone Python program, ideally on a server, but alternatively on an always-connected desktop computer. It periodically queries the Hypothesis API along one or more axes -- url (or wildcard_uri), user, group, tag -- and sends notifications by way of Slack, email, or RSS.

See examples.py for recipes. To run a modified version of it, copy hypothesis.py (from https://github.com/judell/Hypothesis), h_notify.py, and examples.py into a directory, adjust examples.py as needed, and run python examples.py.

The pickle argument to methods like notify_slack_url_activity, notify_slack_group_activity, notify_email_tag_activity, and notify_rss_group_activity names a file that's created, then updated, to remember the IDs of annotations already seen. So, for example, this call ...

notify_slack_url_activity(url='https://web.hypothes.is/*', token=default_token, pickle='urls', channel='test', hook=default_hook)

... remembers IDs in urls.pickle.

Slack

Web hook

You'll need an "incoming web hook" which you create in Slack: https://api.slack.com/incoming-webhooks

@-mentions

To enable Slack @-mentions, create a file called slack_namemap.json like so:

{
  "https://hooks.slack.com/services/T03Q...gyzy" :
    {
    "@dave": "UC...DG",
    "@dwhly": "U0...CT",
    "@hmstepanek": "U8...2W",
    "@judell": "U0...AV",
    "@nateangell": "U3...U9",
    "@katelyn": "U8...72",
    }
}

The values are internal Slack IDs which you can find at https://api.slack.com/methods/users.list/test

Note that Slack usernames may be, but are not necessarily, the same as Hypothesis usernames. If I want to notify Dave Wolfe, whose Hypothesis username is dwolfe, I'll need to write his Slack handle, @dave, in the body of an annotation that's posted to a page monitored by this service.

RSS

RSS feeds are inherently unauthenticated, but access to Hypothesis private annotations requires authentication, so you can't use https://hypothes.is/stream.rss or https://hypothes.is/stream.atom to receive feeds of private annotation activity.

This tool authenticates to the Hypothesis API and produces XML files that you can then serve to RSS readers at unauthenticated-but-secret URLs. You will, however, need to host those files where RSS readers can get them.

The pickle argument in this case also names an XML file that contains an RSS feed. So, for example, given this call ...

notify_rss_group_activity(group='8gk9i7VV', groupname='Anyone Can Join', token=default_token, pickle='8gk9i7VV')

... the IDs are remembered in 8gk9i7VV.pickle and the feed is generated into 8gk9i7VV.xml.

email

You'll need to set up credentials like so:

default_smtp_server = 'smtp.example.com' 
default_email_sender = 'hypothesis.notifier@example.com'
default_email_password = 'q1...Nm'
