Welcome to jarjar’s documentation!

Jarjar is a python utility that makes it easy to send slack notifications to your teams. You can import it as a python module or use our command line tool.

What Can Jarjar Do For Me?

Jarjar was developed at the Austerweil Lab at UW-Madison as a tool for scientists. We use it for all sorts of things, such as:

  1. Sending a message so that we know when long-running processes have finished.

  2. Sending notices when scheduled tasks have failed.

  3. Sending out daily positive vibes.




Installation is simple!

pip install jarjar

My guess is that you’ll want to create jarjar’s config file, .jarjar. This tells jarjar what you’d like to use as a default for your slack team’s webhook, the channel to post to, and the message it sends. Don’t worry, you can over-ride these anytime.

Jarjar automatically looks for .jarjar in the current working directory as well as the user home (~), so edit this snippet and throw it one of those places:

message='Custom message'

If you don’t know your team’s webhook, you might have to make one.

Python API

Use the jarjar python api like:

from jarjar import jarjar

jj = jarjar() # defaults from .jarjar

# send an attachment
jj.attach({'meesa': 'jarjar binks'}, message='Hello!')

Jajrar also supports decorator and Jupyter magic workflows!

Command Line Tool

We also made a command line tool for use outside of python scripts. The command line tool adds functionality to execute processes and send messages when they are complete.

jarjar sleep 1 -m 'Meesa took a nap!'

And then in your slack team:


Custom attachments are not supported in the CLT at this time, but everything else is:

jarjar -m 'Meesa jarjar binks!'
jarjar -m 'Hi, everyone!!' --webhook '<your-url>' -c '#general'
