Numbas is an open-source system for creating tests which run entirely in the browser. It has been developed by Newcastle University's School of Mathematics, Statistics and Physics.

For more information about Numbas and what it does, see our website at numbas.org.uk.

Documentation for Numbas users is at numbas-editor.readthedocs.org.

This repository contains the Numbas compiler, which runs as standalone Python 3, but the most convenient way to use Numbas is through the web-based editor.

A publicly-available editor, requiring no set-up, is available at numbas.mathcentre.ac.uk. Or, you can follow our instructions for Windows, Mac, or Ubuntu to install your own instance.

If you decide to run your own installation, install the compiler's dependencies with pip install -r requirements.txt.

This repository is just one part of the Numbas ecosystem. See the numbas organisation for the other pieces, including the web-based editor, extensions, and VLE integrations.

Numbas is open source, and we welcome contributions of any sort. Bug reports or feature suggestions can be added to the GitHub issue tracker, or emailed to [email protected].

See our page on contributing to Numbas for more information on how you can help.

We keep a list of tasks specifically for new contributors, under the good-first-issue label. There's a corresponding list in the editor repository, too. These tasks should be fairly straightforward to implement without much knowledge of how all the code fits together.

This tool runs on the command line: run python bin/numbas.py to see the options. You can give it the name of a .exam file or pipe one in.

When making changes to the JavaScript runtime, it's a good idea to run the unit tests in the tests directory. These can run in a browser, or on the command-line.

Start a local web server with python -m http.server and go to http://localhost:8000/tests. The tests under tests/jme contain tests to do with the JME system, and tests/parts contains tests to do with the part marking algorithms.

You can run the tests from the command-line using node.js:

Install the dependencies:

cd tests
npm install

Then run the tests with:

npm test

If you make a change, please try to add unit tests to confirm that Numbas behaves as expected.

The Makefile in this repository collects together scripts to run the unit tests, and builds the API documentation. Linux and Mac OS have built-in support Makefiles, but Windows doesn't. On Windows, cygwin provides make.

API documentation for developers is at numbas.github.io/Numbas. This is generated using JSDoc, with a custom template. Run make docs to rebuild the API documentation into ../numbas-docs.
