Hi, I think you can use tex.write() instead of tex.print() (pretty much the same as in lua io functions). Hope this helps Joseph De : Otared Kavian Envoyé le :dimanche 19 mars 2017 16:31 À : mailing list for ConTeXt users 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
