Hi, there are still questions how to use the context.setupheadertexts. - why is on even pages the header not set when using the example below? - how to make odd and even pages carrying a different header text? \setuplabeltext[en][A=Happy New Year] \startluacode function myheadertext(s) context.setupheadertexts{ function() context.labeltext(s) context(": ") end} end \stopluacode \starttext \ctxlua{myheadertext("A")} \input knuth \page \input ward \stoptext Thanks for enlighten me!

It’s explained on page 26 of the cld manual. You should also create your functions in the userdata namespace. \setuplabeltext[en][A=Happy New Year] \startluacode userdata = userdata or { } function userdata.myheadertext(s) context.setupheadertexts{ function() context.labeltext(s) context(": ") return true end } end \stopluacode \starttext \ctxlua{userdata.myheadertext("A")} \input knuth \page \input ward \stoptext Wolfgang
Hi Wolfgang, thank you! For the moment I can do the "project". - Still I wonder how to achieve odd/even page headerstexts. Have a nice weekend Willi On 24 Dec 2011, at 12:02, Wolfgang Schuster wrote:

\setuplabeltext[en][A=Happy New Year]
\startluacode
userdata = userdata or { }
function userdata.myheadertext(s) context.setupheadertexts{ function() context.labeltext(s) context(": ") return true end } end
\stopluacode
\starttext \ctxlua{userdata.myheadertext("A")} \input knuth \page \input ward \stoptext

Here is a TeX example how to set different texts for left and right pages. \setuppagenumbering[alternative=doublesided] \setupheadertexts[\doifoddpageelse{Right page}{Left page}] \starttext \dorecurse{10}{\dontleavehmode\page} \stoptext Wolfgang
Hi Wolfgang, thank you. The reason why I ask this question is, because \setupheadertexts has 4 arguments and I was curious about how this would be solved in context/setupheadertexts. I will look into your solution. I am not sure whether it will fit into the cld-project. Merry Christmas Willi On 24 Dec 2011, at 15:25, Wolfgang Schuster wrote:

Can’t you do stuff like this in a style file where you can use TeX macros. A alternative to the \doifoddpageelse macro is to test whether the page counter is or even with the math.odd function. \startluacode userdata = userdata or { } function userdata.myheadertext(rightpage,leftpage) local rightpage = rightpage local leftpage = leftpage if not leftpage or leftpage == "" then leftpage = rightpage end context.setupheadertexts{ function() if math.odd(tex.count["realpageno"]) then context(rightpage) else context(leftpage) end return true end } end \stopluacode \starttext \ctxlua{userdata.myheadertext("Right page")} \dorecurse{4}{\dontleavehmode\page} \ctxlua{userdata.myheadertext("Right page","Left page")} \dorecurse{4}{\dontleavehmode\page} \stoptext Wolfgang

Hm, the struggle is, that the given example is very much simpler than in the real environment. There I need to change the setupheadertexts according to events being determined in lua-calculations. Therefore I doubt whether I will be able to use a style-file with TeX-macros.
\startluacode
userdata = userdata or { }
function userdata.myheadertext(rightpage,leftpage) local rightpage = rightpage local leftpage = leftpage if not leftpage or leftpage == "" then leftpage = rightpage end context.setupheadertexts{ function() if math.odd(tex.count["realpageno"]) then context(rightpage) else context(leftpage) end return true end } end
\stopluacode
\starttext
\ctxlua{userdata.myheadertext("Right page")}
\dorecurse{4}{\dontleavehmode\page}
\ctxlua{userdata.myheadertext("Right page","Left page")}
\dorecurse{4}{\dontleavehmode\page}
\stoptext
This is indeed a very good approach. I will try it! Thank you very much for your support!
