Katex doc rendering

[Shoeboxam]

I was recently trying to get Katex rendering on docs.rs for a crate I work on. Noticed this crate was able to get it working. It seems you can directly reference a file in your crate.

[package.metadata.docs.rs]
rustdoc-args = ["--html-in-header", "docs/assets/rustdoc-include-katex-header.html"]

I was actually working on this last week and couldn't make the above work. The issue was it attempted to compile all the deps with the same flag, and obviously the deps don't have that path in their repo, so it quickly failed with a File Not Found. Did you manage to find a way around this?

My test crate had no deps, so it didn't trigger that issue. However, the crate I linked does have deps and it works. (!)

EDIT: After adding a dep to my test crate, I still got a successful docs.rs build.
EDIT2: This also comes up: CAD97/katex-doc#4

Neat! I'll give it a shot soon, then.

I hadn't caught the distinction between cargo doc and cargo rustdoc. cargo doc also builds all deps. For local builds I think you could also run:

cargo doc && cargo doc --no-deps *inject html*

#439 fixes this and does it all in docs.rs and locally

This was fixed via #439
