I wish you could just use Obsidian Publish to host sites, but due to the indentation issue you have to control the rendering, which is a bummer.

Obsidian Digital Garden[1] is FOSS, so it might be modifiable parse and output the code pages correctly.

The typical Markdown answer to needing indentation preserved is the "code fence" (triple backquotes ```), though I imagine the problem with that is that Obsidian by default stops dealing with Wikilinks inside fenced code. I don't know Obsidian that well, but maybe there's a way to use a code fence and have it support Wikilinks inside?

A different direction to explore might be to explore proportional font coding techniques that rely less on whitespace. Lisp can be a good language to play with those ideas given whitespace isn't syntactic. Though idiomatic Lisp has certainly relied on semantic whitespace in coding styles for a very long time.

Exactly. Interestingly enough autocomplete is still triggered by [[ inside of a code block which is kind of funny. So writing code blocks works fine, it's just that they won't display with links.

I'm definitely open to proportional font coding techniques being interesting, but in this case with all leading indentation unusable I doubt they'd be enough to get a normal experience. Unless you only write assembly so you can stick to the left margin <taps forehead>.

markdown -> xml -> hack around -> html is essentially a static site generator. https://github.com/commonmark/cmark works really well.
