Re: [NTG-context] making horizontal space in luacode.

      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

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 {}.
