Any way to set the highest header level in output?

[colleen05]

I'm thinking of using this for my static site generator, where articles are written in Markdown and converted to static HTML.

Because websites should really only have one <h1> header, but titles of Markdown documents may have their header start with a single #, I would like to be able to set the highest header "level", such as # being <h2>, ## being <h3>, etc...

Example:

# Hello, world!
## My section
Lorem ipsum dolor sit amet.

would turn into

<h2>Hello, world!</h2>
<h3>My section</h3>
<p>Lorem ipsum dolor sit amet.</p>

Is this at all possible? Or is there already an easy way to parse and replace HTML tags with another Rust library?

Welcome @colleen05! 👋
markdown-rs has sibling projects in the JavaScript ecosystem remark and rehype https://unifiedjs.com/learn/
Those can shift heading levels using https://github.com/rehypejs/rehype-shift-heading

Something similar would be possible in markdown-rs after plugins (#32) are supported. Insights and code moving plugin support forward are welcome!

Thanks for letting me know about rehype!
Not quite what I'm looking for (as I would prefer to have an entirely Rust codebase and am not big on JavaScript in general), although I may be able to port the heading shifting behaviour to Rust as a standalone library.

I still got my answer, though (i.e., it's not possible just yet with markdown-rs, but could be through plugins), so thanks!
