Perseus Exercise Renderer for Kolibri

What is this?

Kolibri is a Learning Management System / Learning App designed to run on low-power devices, targeting the needs of learners and teachers in contexts with limited infrastructure. See learningequality.org/kolibri for more info.

Perseus is Khan Academy's exercise question editor and renderer. See github.com/Khan/perseus for more info.

This package is a wrapper around Perseus which allows it to be embedded and used within Kolibri.


This plugin is bundled with Kolibri - it is unlikely that you need to install it.. If you are running a custom version, you can install it like this:

  1. Inside your Kolibri virtual environment:

    pip install kolibri-perseus-exercise-plugin
  2. Activate the plugin:

    kolibri plugin enable kolibri_exercise_perseus_plugin
  3. Restart Kolibri.

Getting started with development

  1. Clone this repo.

  2. Open terminal in your Kolibri repo.

  3. Run the following commands, with your Kolibri development virtual env enabled:

    make clean
    pip install -e .
    kolibri plugin enable kolibri_exercise_perseus_plugin
  4. Within the perseus plugin repo directory, run the following command, again using your kolibri dev virtualenv:

    cd kolibri_exercise_perseus_plugin
    yarn install
    cd ..
    make dist

Known issues

Development installation version not active

If you ran make dist or make pex on Kolibri with kolibri-exercise-perseus-plugin==x.x.x present in kolibri/requirements/base.txt, Kolibri will generate an kolibri_exercise_perseus_plugin instance inside its kolibri/dist folder and bundle it for further distribution. That means manually installing kolibri_exercise_perseus_plugin for development won't take any effects. One way to fix this issue is to run make clean on Kolibri.
