Modify the Programming Language

You can change the programming language implementation that is used by the Cadet Frontend (for example the Playground), by giving it a different js-slang distribution. In order to run your own, (possibly) modified cadet frontend using your own (possibly modified) language implementation, do the following:

• Follow the cadet-frontend Installation README
• Change your frontend if needed; build the fontend if needed
• Install yarn
• Install js-slang
• Change your js-slang if needed
• Build js-slang using yarn build
• Copy over folder js-slang/dist to cadet-frontend/node_modules/js-slang/dist`
• Start frontend using npm start

To change the language implementation in the production system, fork js-slang and use package.json in cadet-frontend to point to your fork.
