Hi all,
Below are three methods of defining a dimension / dimension string in ConTeXt --- the first two boil down to storing a string in a macro, the last is a proper TeX dimen. I want to access these dimensions from Lua.
I can access the dimen via tex.dimen.ColumnC, but how can I access the macro contents? If there is no solution, I can always explicitly pass the value to Lua with
\ctxlua{var = '\measure{ColumnA}'}
, but I want to know if there is a Lua-only method to get these values.
%% MWE \definemeasure[ColumnA][10mm]
\def\ColumnB{20mm}
not a general solution %%% \def\ColumnB{20mm} \starttext \startluacode local c = "\\csname ColumnB\\endcsname" context("ColumnB=%s",c) \stopluacode \par \toks0=\expandafter{\ColumnB} \startluacode context("ColumnB=%s",tex.toks[0]) \stopluacode \stoptext -- luigi
