groupby

Workbench module that creates a row per group of input rows.

Developing

First, get up and running:

tox

This will download dependencies and run tests. It should pass.

To add a feature on the Python side:

1. Write a test in tests/
2. Run tox to prove it breaks
3. Edit groupby.py to make the test pass
4. Run tox to prove it works
5. Commit and submit a pull request

To develop continuously on Workbench:

1. Check this code out in a sibling directory to your checked-out Workbench code
2. Start Workbench with bin/dev start
3. In a separate tab in the Workbench directory, run bin/dev develop-module groupby
4. Edit this code; the module will be reloaded in Workbench immediately
