Thank you for this, I hadn't done anything in litex during summer and I missed this one. Elisp didn't have fractional data type so I should do something about this if we're using clisp. Can you think of any other data types that might have similar results?
I'll write a function to parse the slime output for this one.
Can you test and see if it's fixed in the linked pull req? Felt like a ducttape for now. turns out elisp didn't have ratio
datatype so it was reading 1/2
as symbol so as a symbol it was formatted in the way symbols do (ignoring /
as I used it to separate greek alphabets in symbol earlier), might need to fix that too... It'd have at least been 1/2
instead of 12
if that wasn't there.
If I tried to solve the expressions you gave in step by step format litex-solve-all-steps-align
then we get this:
\begin{align*}
x& = \frac{1}{2}\\
& = \frac{1}{2}
\end{align*}
It looks repetitive because first one is values substitution and last one is the fractional value.
Considering other problems as well looks like overall I can't make litex automate everything but just help you generate the draft to fine tune.
The cases I've tried work great! And yeah, LiTeX is really useful for automating part of the note taking process for me. I write my maths and physics notes in lisp and it's a great time saver to be able to both evaluate and get TeX out of it. It isn't a big issue that there are a few manual steps as it does so much already.
I've merged it, melpa should have the new version when it builds it next I guess. I do think I'll end up changing the greek letters' separate character from '/' to '.' because of this and other reasons (for eg, I'd like variables to be able to have names like "dx/dt").
For example the following
Gets solved to
$$a = 12$$
When it should be
$$a = \frac{1}{2}$$
This is only an issue when using integers, and it seems to be because
1/2
gets returned by slime and Litex doesn't have code to handle it.
