Hi,
I've been porting Paul Taylor's prooftree.sty
(https://www.paultaylor.eu/proofs/) to ConTeXt, which seemed quite easy.
There's just one adjustment to make:
291c292
< \else \dimen6=\fontdimen22\the\textfont2 % height of maths axis
---
> \else \dimen6=\the\dimexpr\triggeredmathstyleparameter\Umathaxis % height of maths axis
It seems that ConTeXt stores the math font in \textfont0 instead
of \textfont2 as LaTeX does.
Now my question is: is \textfont2 used at all? (I grepped occurences
of \textfont0 and \textfont1) Then I could just copy the \textfont0 to
\textfont2 before loading the macro and would not require any patches.

i don't know what / how latex does it but in context we have these
parameters in fam 0

indeed, just get it from fam zero, or
\the\Umathaxis\fam
assuming thta \fam has some reasonable value
(btw, assume opentype math fonts and not some old school 8 bit sssembly)
