About included languages ?

[soykje]

Hello,

First, thank you for this great work! 👏

I'm getting started on a SSG NextJS project, and I was wondering what was the purpose of the limitation of included languages? I guess this is about bundle size and performances, but what about just using something like the babel-plugin-prismjs, instead of the method described here?

I'll be happy to discuss that!

Thx again

Hi there, I'm trying to include syntax highlighting for Rust in my markdown files but Rust is not part of the included languages. Any idea of how I can add syntax highlighting for Rust?

@jeffzh4ng Hi, Rust language is included in PrismJS, but the bundled version of prism-react-renderer does not include all of them. You can follow the guidelines from FAQ to add support, or install the babel-plugin-prismjs package (like I did) and then declare your specific languages directly in the Babel config file (see here for more details). Btw do not forget that using this method you'll have to use the 'classic' Prism bundle, not the one from prism-react-renderer... The babel plugin will take care of build size according to your specific configuration.

@soykje Thanks for the response. I'm not experienced with Gatsby or Prism at all. Where would I place the code snippet that the FAQ is telling me to do?

@jeffzh4ng you'll have to pass Prism (the default export from prismjs) to the Prism prop of this library.

Then either you make a file that just reexports Prism to add Prism manually to the highlighter and import all the highlighters you need or you can use the linked Babel plugin instead and won't need your own file.

Got it, thank you 🙏
