Hi Leah,
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.
i don't know what / how latex does it but in context we have these parameters in fam 0
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. 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) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
