Hi,
Consider the following MWE:
\definetyping[T] \definemode[mode][yes] \starttext \doifmode{mode}{% \startT Bla \stopT} \stoptext
Compilation with the currently latest ConTeXt LMTX (ver: 2021.03.17 17:46 LMTX fmt: 2021.3.18) fails with:
tex error > runaway error: end of file encountered mtx-context | fatal error: return code: 1
Compilation is successful if I replace doifmode{mode}{...} by \startmode[mode]...\stopmode.
Is there anything I'm missing? (This could be a bug.) not a bug, just the way tex works .. modes cannot know that what goes into an argument is something verbose
but you can use this (also more efficient here):
\definetyping[T] \definemode[mode][yes] \starttext \startmode[mode] \startT Bla \stopT \stopmode \stoptext
% there's also \startnotmode
Thank you for hinting at the environment form. The problem with this is, that it cannot be nested, and that there is no "else" form. E.g: \startmode[A] ... mode A \startmode[B] ... mode A and mode B \elsemode ... mode A and not mode B \stopmode \stopmode I know that there is \start(not)mode and \start(not)allmodes, but there seems to be no way to use a general boolean expression such as: \startmodes[A and not B] ... \stopmodes Of course we can do this in lua: if tex.modes["A"] and not tex.modes{"B"] then ... end Keep up your excellent work!
