Eukleides extension for Numbas

This extension for Numbas contains a port of the Eukleides geometrical drawing language by Christian Obrecht, with extensions to make diagrams interactive and accessibility improvements.

Using this extension

This extension is available on the public Numbas editor at numbas.mathcentre.ac.uk.

To use this extension with your own instance of the editor, you only need the file dist/eukleides.js.

Documentation

There's documentation on how the extension works and a full function reference.

See the demo page for a gallery of examples, and the interactive playground to draw your own diagrams.

Development

The extension is written using ES6 syntax and features. This is compiled with babeljs to ES5, which is supported by lots more browsers.

dev_demo.html and dev_playground.html load the source scripts directly, on browsers which support ES6.

To install the babeljs tools, first install nodejs and then run:

npm install

Then, when you make a change to the source, run

make

to compile the scripts in the dist folder.

You might need to set the environment variable NUMBAS_RUNTIME_PATH to the location of your Numbas compiler directory.
