Strange backgroundcolors with showgrid and luacode
Dear all, When typesetting an old list of exercises, I noticed that when \showgrid is active and a luafunction is called, there is some unwanted and strange background colors (gray and blue, or yellow and blue). Thes background colors seems to show up on an unfilled page when a lua function is used, and I could come up with the following minimal example which gives the attached PDF. Could someone, please, tell me what I am doing wrong? Best regards: OK %%%% begin test-strange.tex \showgrid %\setuplayout[grid=yes] \startluacode AdditionTest = function(nn) local a = {} local b = {} for i = 1,nn do a[i] = i b[i] = nn - i end context.midaligned("\\bfa Exercises") context.blank() context.startcolumns { n = 3 } context.starttabulate { "|r|c|r|c|r|" } for i=1,nn do context.NC() context(a[i]) context.NC() context.mathematics("*") context.NC() context(b[i]) context.NC() context("=") context.NR() end context.stoptabulate() context.stopcolumns() context.page() end \stopluacode \starttext \ctxlua{AdditionTest(12)} % the background colors, gray and blue, show up when a lua function is called % \ctxlua{AdditionTest(120)} % the background colors, yellow and blue, show up when a lua function is called % \input knuth % the background colors do not show up here \stoptext %%%% end test-strange.tex

\showgrid highlights different page elements with colors but you can change the output https://www.mail-archive.com/ntg-context@ntg.nl/msg90312.html Wolfgang

Hi Wolfgang, is there any way to get the lines from \showgrid in black instead of red? Many thanks for your help, Pablo -- http://www.ousia.tk
\definepalet[layout][grid=black]

Many thanks, Marcus Vinicius and Wolfgang, for your replies. This is the only way it works: \definepalet[layout][grid=black] %~ \setuppalet[layout] [grid=black] \showgrid \starttext \ConTeXt\ is awesome! \stoptext I don’t know whether I’m missing something, but \showsetups{setuppalet} only shows this: \setuppalet [.*.] * NAME Many thanks for your help, Pablo -- http://www.ousia.tk

Many thanks for your help,
It's my fault, in this case there is only a single command to create and change palet values. Wolfgang

Many thanks for your explanation, Wolfgang. I found this code in ConTeXt (syst-aux.mkiv): \starttext \doloopoverlist {red,green,blue} { \setuppalet[\recursestring] \doloopoverlist {light,normal,dark} { \blackrule[color=\recursestring, width=\textwidth]\par } } \stoptext Is it intended that all nine lines are black?

Is it intended that all nine lines are black?
Yes, because there are no predefined palets with the names red, green or blue. \definepalet [red] [ light=lightred, normal=middlered, dark=darkred] Wolfgang
