Hi Wolfgang, Thank you for your attention and the explanation regarding the « hash option » and why the sudoku module written by Jairo does not work. However I was reporting the issue when I tried to typeset the example file with LMTX (version 2022.07.06 21:42). As a matter of fact I am far from understanding what the « arguments = { « hash » } » is supposed to do in interfaces.implement in the code you sent… Best regards: Otared

Hi Jairo,

You sent a message last year about your Sudoku module, and today, out of curiosity, I wanted to test it. Unfortunately it stops with an error message at line 76 of the file t-sudoku.mkiv, where you have:

\def\sudokufunction_direct[#name][#parameters]#content

I would appreciate if you could tell me whether you have a working version of you module, or what one has to change in order to typeset your examples.

The error is unrelated to the sudoku module and when you use LMTX the error disappears.

The real problem can be seen in the following minimal example and is related to the "hash" option for the argument key.

%%%% begin example \starttext

\startluacode interfaces.implement { name = "test", public = true, arguments = { "hash" }, actions = function(t) print(table.serialize(t)) end, } \stopluacode

\test[text=Hello]

\stoptext %%%% end example

Wolfgang

Hi Wolfgang, Thank you for your reply and the explanations about the function « interfaces.implement ». Regarding the examples given by Jairo, you are correct: those examples can be typeset with LMTX. I did a mistake when in TeXShop I saved the file « t-sudoku.mkvi » under the name « t-sudoku.tex »: indeed this creates an error in LMTX as well in earlier versions of ConTeXt… (maybe a colateral consequence of the heat wave in France :-) I apologize to you and Jairo for having caused any trouble. Best regards: Otared

I have no problems with the examples at the end of the module and LMTX, only when I use LuaTeX a error appears.

The 'interfaces.implement' functions creates the command \test and 'arguments={"hash"}' creates the argument which accepts key-val lists ([text=Hello]).
