Hi all,
I try to call a lua-function, but it seems that it doesn't work if the
parameter contains squared brackets. Here is a short example:
\starttext
sometext
\reference[myref]{}
is
\ctxlua{tex.print(\atpage[myref])}
\stoptext
Is there a way to mask the brackets?
Best regards,
Martin

I have a function like this: \startluacode function pagesetup(page1,page2) if page1==page2 then tex.print(page1) elseif page1+1==page2 then tex.print(page1..'f.') else tex.print(page1..'-'..page2) end function \stopluacode \starttext \reference[myref1]{} \page \reference[myref2]{} \ctxlua{\at[myref1],\at[myref2]} \stoptext But I find no way that it works with the two references with brackets. Somewhere else I have an similar problem when I work with counters. The lua-function there doesn't accept this \ctxlua{dosomething(\getnumber[mynumber])} ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

One question: is the same possible with linereferences as with pagereferences? It's very important for the critical edition project I'm working at.
