Can \note repeat its footnote?

Can \note repeat its footnote?

[Stefan Wachter]

Hi all!

The \note[xxx] command is used to reference a previously defined 
footnote. Is it possible that the previously defined footnote is 
repeated if a page break had occured between the \footnote[xxx]{bla bla 
bla} and the corresponding \note[xxx] command?

Thanks for your attention,
--Stefan

I've tried to build a macro based on \ifnum\currentpage=\at[xxx] (or
similar), but without success. In LaTeX I've used something like this:
\ifthenelse{\thepage=\pageref{LastPage}}
Perhaps, there is something similar in ConTeXt?
Cheers, Peter

it's incredible what kin dof wishes users can come up with -)

\def\myfootnote[#1]#2% let's guess that #2 is without catcode problems  
  {\setxvalue{note:#1}{\footnote{#2}}\footnote[note:a:#1]{#2}}

\def\mynote[#1]%
  {\removeunwantedspaces
   \pagereference[note:b:#1]%
   \doifreferencefoundelse{note:a:#1}
     {\edef\NotePageA{\number\currentrealreference}%
      \doifreferencefoundelse{note:b:#1}
        {\edef\NotePageB{\number\currentrealreference}%
         \ifnum\NotePageA<\NotePageB\relax
           \getvalue{note:#1}%
         \else
           \note[note:a:#1]%
         \fi}
        {\note[note:a:#1]}}
     {\note[note:a:#1]}}

\starttext

test \myfootnote[funny]{first occurence} test\mynote[funny]
test \myfootnote[again]{first occurence} \page test \mynote[again]

\stoptext

hardly tested

Hi Hans,

thanks for your reply. Unfortunately your solution does not work 
correctly. The following example produces one footnote at the first page 
  but no footnote on the second page.

\starttext

funny\myfootnote[funny]{funny} funny\mynote[funny]
\page
funny\mynote[funny] funny\mynote[funny]

\stoptext

--Stefan

PS: Would it be possible to use the same footnote mark again when a 
footnote is repeated?

sure but this needs some thought (for instance clashing numbers/symbols)

\def\myfootnote[#1]#2% let's guess that #2 is without catcode problems
  {\setgvalue{note:t:#1}%
     {\setxvalue{note:l:#1}{\getvalue{note:n:#1}}%
      \footnote[note:a:#1:\getvalue{note:l:#1}]{#2}}%
   \setgvalue{note:n:#1}%
     {1}%
   \getvalue{note:t:#1}}%

\def\mynote[#1]%
  {\removeunwantedspaces
   \scratchcounter\getvalue{note:n:#1}\relax
   \edef\NoteNumber{\the\scratchcounter}%
   \doglobal\incrementvalue{note:n:#1}\relax
   \doifreferencefoundelse{note:a:#1:1}
     {\edef\NotePageA{\number\currentrealreference}%
      \doifreferencefoundelse{note:a:#1:\getvalue{note:n:#1}}
        {\edef\NotePageB{\number\currentrealreference}%
         \doifreferencefoundelse{note:a:#1:\NoteNumber}
           {\ifnum\currentrealreference=\NotePageB\relax
              \pagereference[note:a:#1:\getvalue{note:n:#1}]%
              \note[note:a:#1:\getvalue{note:l:#1}]%
            \else\ifnum\NotePageA=\NotePageB\relax
              \pagereference[note:a:#1:\getvalue{note:n:#1}]%
              \note[note:a:#1:\getvalue{note:l:#1}]%
            \else
              \getvalue{note:t:#1}%
            \fi\fi}
           {\ifnum\NotePageA=\NotePageB\relax
              \pagereference[note:a:#1:\getvalue{note:n:#1}]%
              \note[note:a:#1:\getvalue{note:l:#1}]%
            \else
              \getvalue{note:t:#1}%
            \fi}}
        {\pagereference[note:a:#1:\getvalue{note:n:#1}]%

Re: Can \note repeat its footnote?

[Stefan Wachter]

Hi Hans,

many thanks for your help. Now it works. Great!

I try to come along without having the same footnote marker for repeated 
footnotes. (This would make sense only if footnotes are sequentially 
numbered over a whole document.)

Thanks again,
--Stefan
