Re: [NTG-context] parameters TeX->LuaTeX
And \ListSort[[abc]]{value} turns out to be worse: doesn't makes it into LuaTeX at all. dr.

[NTG-context] parameters TeX->LuaTeX
There is something I do not understand in the passing of parameters from TeX to LuaTex. This is my TeX definition: \def\ListSort[#1]#2{\directlua{hvdm.listsort([===[#2]===],[===[#1]===])}} Calling \ListSort[sep={ + }]{} delivers the string 'sep={ + }' into LuaTeX as the printout in the logfile shows and as intended. However in \ListSort[{ + }]{} the braces have disappeared and transferred is nothing more than ' + '. Why is the transfer messing up the character string I am passing by removing the outer braces? Is this a bug or is it an unavoidable consequence of the TeX-LuaTeX interface? dr.
