How to add a custom language to be used with mkdocs?

[mattias-mohlin]

I've tried to follow the steps at https://prismjs.com/extending.html#creating-a-new-language-definition for adding a new language definition to Prism. Everything works fine on the test.html page and I can see the keywords of my language colorized. However, how should I proceed from here to actually getting a prism.js file that contains my new language which I can include in my mkdocs site?
I also notice something strange when opening the download.html file. My language appears in the list, but with a size of 0 KB.
I think I'm missing something obvious, and I'm pretty sure that if I just can get the correct prism.js file generated then it will work with mkdocs because it works for a built-in language like C++.

To get the download page working locally, you have to run it with a local HTTP server (e.g. this one). Then the download page will work.

Also, be sure to run npm run build before "downloading" the generated bundle. The download page load components.js, so that file has to be rebuilt.

My language appears in the list, but with a size of 0 KB

That's because we get the sizes from our GitHub repo. Since your languages isn't included, it will be displayed as 0KB.

However, this doesn't affect the bundle. It's just user-facing information.

Thanks, with a local HTTP server it works fine!
