Hi,

I think you can use tex.write() instead of tex.print() (pretty much the same as in lua io functions).
Hope this helps

Objet :[NTG-context] How to use tex.print in ctxlua

Hi,

I would like to print in a text the values of a array computed in a  \startluacode …. \stopluacode combination.
How can I do it properly? Please have a look at the example below and its output, which is not satisfactory because the right parenthesis is separated from the number by a space. How can I suppress this unwanted space? 
For instance I get (1, 103 ) instead of (1, 103).

Thanks in advance for any help,
Best regards: OK

%%% begin ctxlua-print.tex
\starttext
\startluacode
	n = 6 ;
	vecteurX = {} ;
	for i = 1,n do
		vecteurX[i] = i ;
	end
	vecteurY = {} ;
	for i = 1,n do
		vecteurY[i] = 3*vecteurX[i] + 100 ;
	end
	for i = 1,n do
		context("(") 
		tex.print(vecteurX[i]) 
		context(", ") 
		tex.print(vecteurY[i])
		tex.print(")")
		context.par()
	end
\stopluacode
\stoptext
%%% begin ctxlua-print.tex
