wasm-pandoc VS panflute

https://github.com/y-taka-23/wasm-pandoc (works, but no lua filters)

Interesting idea re:internal links. For sufficiently complex issues of this nature, pandoc filters[0] are a powerful tool for this kind of mid-conversion processing. I've made some cool projects with the Python package panflute[1]

Something that is quite suited to little mini projects with python is writing pandoc filters. The basic idea of pandoc is to convert written documents of some file type (the main source type is typically markdown) into another document type, for example latex, pdf, docx, odt... Now of course there will be certain things that pandoc cannot do quite well enough given its versatility. So it gives users the option to write [simple filters](https://pandoc.org/filters.html#summary) and apply them. This way you can also come up with your own syntax/tags and whatever in markdown and convert that to an arbitrary formatting instruction in another document type. Look into something like panflute and maybe you can come up with your own filters.
