Re: making horizontal space in luacode.

[Jeong Dal]

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

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 {}.

\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

making horizontal space in luacode.

[Jeong Dal]

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?

2. There is no white line even though I put "\blank[big]" between Frame(bring it from MetaFun) and text as in the following example.

\starttext

%%%%%%%% framed Text
\startuseMPgraphic{FunnyFrame}
picture p ; numeric o ; path a, b ; pair c ;
p := textext.rt(\MPstring{FunnyFrame}) ;
o := BodyFontSize ;
a := unitsquare xyscaled(OverlayWidth,OverlayHeight) ;
p := p shifted (2o,OverlayHeight-ypart center p) ;
drawoptions (withpen pencircle scaled 1pt withcolor .625red) ;
b := a superellipsed .95 ;
%fill b withcolor .85white ;
draw b ;
b := (boundingbox p) superellipsed .95 ;
fill b withcolor .425green;%.85white ;
draw b ;
draw p withcolor black ;
setbounds currentpicture to a ;
\stopuseMPgraphic

\defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}]
\defineframedtext[FunnyText][frame=off,background=FunnyFrame, offset=\bodyfontsize, width=\overlaywidth]%.8\textwidth]
\def\StartFrame{\startFunnyText}
\def\StopFrame {\stopFunnyText}
\def\FrameTitle#1%
{\setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut\ss\bf\white #1\hss}}}

This is a test line file for blank spaces.
\blank[big]  % white line is wanted
{\FrameTitle{Test}
\StartFrame
\startitemize[n]
\item the first line.
\item the second line.
\item the third line.
\stopitemize
\StopFrame
}
\blank[big]  % white line is wanted
Here is another test line.

\stoptext

What should I do to make a blank line before and after 

Thank you.

Best regards,

Dalyoung
