Kolibri plugin for rendering Khan Academy Perseus style exercises

Project description

What is Kolibri?

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. A user can install Kolibri and serve the app on a local network, without an internet connection. Kolibri installations can be linked to one another, so that user data and content can be shared. Users can create content for Kolibri and share it when there is network access to another Kolibri installation or the internet.

See for more info.

What is Perseus?

Khan Academy’s exercise question editor and renderer.

See for more info.

What is this plugin?

A Perseus renderer wrapper for Kolibri that can track learning progress and save to the database.


This plugin is bundled with Kolibri. 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 exercise_perseus_renderer enable
  3. Restart Kolibri.

Development guide

  1. Clone this repo.

  2. Open terminal in your Kolibri repo.

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

    kolibri plugin kolibri_exercise_perseus_plugin enable
  4. Then run the commands to install frontend packages in Kolibri, this plugin will have its dependencies recursively installed:

    yarn install

    Make sure that this message DOES NOT appear in your logging output of yarn install, it means that you are not using the development version:

    WARNING  assets/src/module.js not found for plugin exercise_perseus_render_module.
  5. After cloning for the first time, or if you made any changes to the project, you need to rebuild it:

    make assets

Updating translation strings

This is currently broken, download files manually from CrowdIn

To download the latest translation strings for this plugin, make a crowdinSecrets.js file from the template in the repo root, and put your kolibri project API key in there. The KA API key can be set to null. Then execute the following commands:

cd kolibri_exercise_perseus_plugin
yarn run download-translations

Updating Perseus

In case you update Perseus (bundled in this repo), please run this command afterwards:

make assets

Release plan and version scheme

The versioning of this plugin does not follow Kolibri’s release plan. We plan to make it possible to upgrade and distribute this plugin independently from Kolibri, as with all other plugins.

That means that the versioning and releasing of kolibri_exercise_perseus_plugin is unrelated to both Kolibri and Perseus.

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 exercise_perseus_renderer instance inside its kolibri/dist folder and bundle it for further distribution. That means manually installing exercise_perseus_renderer for development won’t take any effects. One way to fix this issue is to run make clean on Kolibri.

How to publish to PyPi?

  1. Follow the instructions above to installing the plugin for development.

  2. From the Kolibri directory run the frontend build command.

  3. Update to a newer version.

  4. Terminal move to the root level of repo dir and run the following command to publish to PyPi:

    make release
