How to add/enable a new language for highlighting?

[finikm]

I am trying to highlight some .proto files, but regardless of what I try, I haven't manage to do it.

While they are supported by Shiki (https://github.com/shikijs/shiki/blob/main/docs/languages.md), I cannot use proto in highlight.preload. Doing some digging, I saw that Nuxt Content v2 uses shiki-es, and Protobuf is not in its set of BUNDLED_LANGUAGES. I came across a similar issue, which while it's resolved, it didn't help.

Any ideas are welcomed :)

Thanks

Have you tried configuring the nuxt.config.ts for syntax highlight?

  content: {
    highlight: {
      preload: [
        'c',
        'cpp',
        '<any language supported by Shiki>'
      ],
  }
}

Indeed I tried, I get typescript error that the language is not a valid option, and if I try to bypass it (i.e. preload: ['proto'] as any) I get a runtime error.
