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}
\newdimen\ColumnC
\ColumnC=30mm
\startluacode
-- print values to stdout
logs.report('====')
logs.report('ColumnA', context.measure('ColumnA'))
logs.report('ColumnB', context.ColumnB)
logs.report('ColumnC', tex.dimen.ColumnC) -- prints in scaled points
print('====')
\stopluacode
Cheers,
Sietse
