plankalkul VS CalcuLaTeX

Yes, I've written grammars/languages before (e.g. https://github.com/alexpdp7/plankalkul/ ). The problem is that Markdown languages pose their own challenges, so it's hard to find a standard parser that works well for them.

If anyone's interested, the source code is at https://github.com/alexpdp7/plankalkul/ ; it uses GH Actions, so it's quite easy to make modifications and run your own. It's implemented completely in Rust (using WASM).

Heh, I'm starting a related project https://github.com/alexpdp7/plankalkul/

Hey HN, I created CalcuLaTeX because I was frustrated with my workflow for chemistry and physics homework. Generally, I'd use the Python REPL as a calculator and type each problem into LaTeX to turn it in. CalcuLaTeX merges these two steps and makes it easier to reason about calculations by real time visual feedback.

I've posted on r/rust as well (https://www.reddit.com/r/rust/comments/lqn5aa/calculatex_a_p...), and there seems to be interest in using it for scientific papers and such.

The only alternative I know of is PTC MathCAD, which is quite powerful and definitely worth looking into. However, it's quite expensive and Windows only.

The main repo (a Rust library and basic CLI) can be found here: https://github.com/mkhan45/CalcuLaTeX

The website repo using WASM and very hacky JS can be found here: https://github.com/mkhan45/CalcuLaTeX-Web

It supports basic unit conversion via the Unit hints. E.g. you can write 1 hour = ? days. A long term goal is proper Unit coercion which is kind of hard to explain but I did my best in this issue https://github.com/mkhan45/CalcuLaTeX/issues/3.

I'm still working on https://github.com/mkhan45/CalcuLaTeX. I'm hoping for it to be ready for my chemistry quiz next week. I've created a very basic web interface via WASM here: https://mkhan45.github.io/CalcuLaTeX-Web/.
