I love this very smooth design - nice!

In similar vein, I like to do literate coding in http://raku.org and jupyter notebooks like this https://gist.github.com/librasteve/ac6308f3eb52dd56cb9092de6... which is described at https://rakujourney.wordpress.com/2023/08/31/drax-on-jupyter...

Looks very complete! That said, one thing I immediately tried was `3^3^33 = ?`, which was somehow interpreted as (3^3)^33 even though it was clearly formatted as 3^(3^33). `3^(3^33) = ?` failed with a cryptic error message as well. Also `4 \bmod 3 = ?` nor `4 % 3 = ?` didn't work---expected to evaluate to 1 (later learned that `mod(4, 3)` is required, but seems an unusual requirement to me).

Quick feedback from a couple of minutes of playing around:

The unit aware calculations generate error messages that aren't very helpful. In addition to better error messages, i feel that the errors should be reported as you type instead of requiring the user to press enter, see the error, then go back and edit. It would also be nice if it could automatically pick a unit for the result.

I'm impressed. Many years ago I worked on something like this but this one is a much better result. It even works well on mobile.

The documentation, linked at the top of the page, is excellent.

Has anybody worked out how to do a local install of Hurmet?

Brilliant! Testament of an Executable Specification.
