Hi all,
I’m trying to write some dimensions to a file, e.g.
\startluacode
io.savedata("settings.txt", context("\\textwidth"))
\stopluacode
But that context() construct is nil.
There’s probably a simple solution... ;)
Greetlings, Hraban

Found it myself:
number.todimen(tex.dimen.textwidth)
Sorry for the noise.
But now I need the current font name, even better the current values for rm, ss and tt fonts.
I found p.123 of cld-mkiv.pdf, but don’t know how to address these values.

\starttext

io.savedata("settings.txt", number.topoints(tex.dimen.textwidth))
\stopluacode
\typefile{settings.txt}
\stoptext
