Dear Aditya, Hans Both solutions work well. It is really efficient to write matrix in ConTeXt + lua. I am enjoying the benefit of lua in ConTeXt. Thank you. Best regards, Dalyoung

\definehspace[skip][3em] \starttext \startluacode context("Some text") context.hspace{"skip"} context("More text") \stopluacode \stoptext

Dear all,

1. I'd like to make a horizontal space using \hspace[3em] inside luacode.

But context.hspace({3em}), context.hspace({"3em"}), context.hspace("3em") don't work. And print(" ") doesn't work either.

How to make some horizontal space in luacode?

\hspace does not accept dimensions. The syntax for hspace is

\definehspace[whatever][3em]

\hspace[whatever].

So, you need:

\definehspace[skip][3em] \starttext \startluacode context("Some text") context.hspace{"skip"} context("More text") \stopluacode \stoptext

Indeed this is the best way. At some point I'll wrap primitives (maybe in another namespace). If you really want to use context.hskip, you can say context.hskip(false,"10pt plus 5pt") etc as a first false argument will signal a drop of {}.
