Option to capitalize slugs

[wooorm]

I recommend changing the content.

See the source: https://github.com/rehypejs/rehype-slug/blob/main/lib/index.js.
Copy/paste it, remove what you don’t need, change it to do what you want.

toUpperCase makes everything uppercase, you probably don’t want that.

headingRank(node) returns 1, 2, etc for headings. Return for 1 if you don’t want h1.

I appreciate your input. I will try to gradually transition to the new slug structure. For now, I'm using JavaScript within my Astro pages to convert incoming legacy slugs (capitalized in my case) into the new format.

Example:

<script>
  (() => {
    const matchTS = /TS\d+/g;
    const hash = window.location.hash;
    const matches = hash.match(matchTS);
    if (matches) {
      window.location.hash = hash.replace('TS', 'ts');
    }
  })();
</script>

Hey! This project is intentionally simple. So that everyone uses the same slugs. It follows GitHub. So that what you write in markdown will work here. And in VS Code. In as many places.

The goal is to not add other options. It would go against the goal of everyone using the same slugs. The alternative, writing your own plugin, is fine! We recommend learning about ASTs, and this is a good example how to learn about them.

Hi! This was closed. Team: If this was fixed, please add phase/solved. Otherwise, please add one of the no/* labels.

Thanks for your explanation. I really like the idea of creating slugs similar to how GitHub does it, and I want to use this in my projects.

I am building an Astro blog, and I need to make sure it supports some links from an older blogging system. In that older system, some of the links are like #TS2003, but the plugin changes them to #ts2003. I can't update the old content, so how can I fix this and change the way the slug is created by the rehype-slug plugin? I was thinking about building my own transformer that under-the-hood calls rehype-slug and then just runs the toUpperCase on top of it?

Also, I'm wondering if there's a way to choose which heading levels get slugs/IDs. For example, I only want IDs for H2 headings and not for H3 headings. Is there a way to do that?
