LehrGrapht

LehrGrapht is a simple math plotter Word add-in targeting teachers using the FunkFix macro, that is not available with macOS anymore.

Development - AddIn

Environment setup

There are two ways to develop the add-in:

1. Develop without Word integration (e.g., to update how plots are rendered, etc.).
2. Develop with Word integration.

Please read the following sections depending on your needs.

Develop the add-in without Word integration

If you're not developing on the Word integration, you can run the add-in in the web. There's nothing special you need to do, just run npm start and you're good to go!

Develop the add-in with Word integration

If you're developing on the Word integration, you need to run the add-in in Word. Word requires SSL to load the add-in.

Microsoft provides a way to generate a certificate using office-addin-dev-certs. Run npx office-addin-dev-certs install --machine to install the office add-in dev certificates.

Then, create a file .env.local (you can just copy .env and rename it) and change the following variables:

• LEHRGRAPHT_SSL: Set to true to enable SSL.
• LEHRGRAPHT_SSL_KEY: Set to the path of your SSL key file provided by office-addin-dev-certs.
• LEHRGRAPHT_SSL_CERT: Set to the path of your SSL certificate file provided by office-addin-dev-certs.

Now, you run npm start to start the development server. Make sure, it binds to https on port 4200.

Finally, you can run npm run start:office. This will open Word and load the add-in.

When you're done, run npm run stop:office.

Development - Website

You can start the development server for the website with npm run start:website.

There's an environment variable LEHRGRAPHT_WEBSITE_GITHUB_TOKEN. You don't need to provide a value for it. If it's set with the correct permissions it will grab a list of issues from GitHub and displays it as a roadmap.
