Hi,
it tried to do a \atpage command that results a) some page => nothing b) different page => pagenumber with some text (e.g. "auf Seite XY")
\def\atPage[#1]% {\doifnot{\at[#1]}{\currentpage}% {\at[#1]}% }
My problem with this is, that the \doifnot always results as not equal; it is like the types mismatch as if I exchange \at[#1] with a pure number the comparing works. If so, how can the types be corrected?
Additionally - if possible - I would like to add case that the referred page is on the other page but in duplex mode adjacent to the actual page. Is that possible to do this? I unluckily dont know how to make working simple calculation in tex code.
To be complete I found in the file strc-ref.mkiv some notes about a planed \atpage command:
%D A still very rudimentary|/|experimental forward|/|backward %D reference mechanism is provided by the macro \type{\atpage}: %D %D \starttyping %D ... \somewhere{backward text}{forward text}[someref] ... %D ... \atpage[someref] ... %D \stoptyping %D %D In future versions there will be more sophisticated
% 0 = no page reference % 1 = same page % 2 = preceding page % 3 = following page % 4 = backward, same page (todo) % 5 = forward, same page (todo)
But that level of the ambient tex is still out of my scope.
that comment can be deleted as \atpage is defined earlier on anyhow, you can use \startbuffer \starttabulate[|l|l|l|l|] \NC one \NC \atpage[one] \NC \somewhere{(see before)}{(see later)}[one] \NC \NR \NC two \NC \atpage[two] \NC \somewhere{(see before)}{(see later)}[two] \NC \NR \NC three \NC \atpage[three] \NC \somewhere{(see before)}{(see later)}[three] \NC \NR \stoptabulate \stopbuffer \starttext \section[one] {One} \getbuffer \page \section[two] {Two} \getbuffer \page \section[three]{Three} \getbuffer \page \stoptext the next variant (same functionality) is somewhat better \unprotect \unexpanded\def\somewhere#1#2#3[#4]% #dummy gobbles space around #2 {\doifreferencefoundelse{#4}% {\strc_references_by_reference_page_state{#4}{\goto{#1}[#4]}{}{\goto{#2}[#4]}} {[#4]}} \protect ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
