referencing figures with \in

referencing figures with \in

[Hans van der Meer]

[-- Attachment #1.1: Type: text/plain, Size: 966 bytes --]

I used to place references to figures and tables in the following way:

\placefigure[][fig:myfig]{Title}{\useMPgraphic{myfig}{parameters}}
     \in{figure}[fig:myfig]

This however printed a dot instead of the expected "figure #".
Changing to
     \at{figure}[fig:myfig]
again printed the correct reference.

Looking further into this I found:
     \meaning\in --> \protected macro:->\dohandlemathtoken {in}
     \meaning\at  --> macro:->\dohandlecommand {at}

Still, the ConText manual tells me that
     \in{.1}{.2.}[ref] (with {.2.} optional)
should work.

In file core-ref.tex at line 2118 (2007-04-17 version) I find:
%\def\in%
%  {\ifmmode
%     \expandafter\donormalin
%   \else
%     \expandafter\doinatreference\expandafter\currenttextreference
%   \fi}
But I am definitely not in math mode when calling \in.
I did some further experimentation but nothing helped.

Has something changed here or is there something I do obviously wrong?

This needs an example file from you. I just ran:

% hans-prob.tex
\starttext

I used to place references to figures and tables in the following way:

\placefigure[][fig:myfig]{Title}{Content}

\in{figure}[fig:myfig]

This however printed a dot instead of the expected "figure ".
Changing to \at{figure}[fig:myfig] again printed the correct reference.

\stoptext


And it worked fine.

Best wishes,
Taco

Hi Hans,

please post a example, the following works for me:

\starttext

\startuseMPgraphic{circle}
draw fullcircle scaled 1cm;
\stopuseMPgraphic

\placefigure
  []
  [fig:ref]
  {Text}
  {\useMPgraphic{circle}}

\in{figure}[fig:ref]

\stoptext

Wolfgang

Taco and Wolfgang,

Here is your counterexample:

\setupcaptions[number=no] % <<<<<< the culprit
\starttext

I used to place references to figures and tables in the following way:

\placefigure[][fig:myfig]{Title}{Content}

mind the {\bf setupcations}, now \type{\in{figure}[fig:myfig]}-->\in 
{figure}[fig:myfig] and does not result in the reference.

This however printed a dot instead of the expected "figure ".
Changing to \type{\at}\at{figure}[fig:myfig] again printed the  
correct reference.

\stoptext

Since you are referencing a non-existing number, I cannot say I am
very surprised get weird output.

The problem is that the reference is actually resolved, but it has
no content (thanks to number=no), and that triggers the special
handling for anonymous references. If the figure appears on a
different page, context will print a triangle pointing to the
left or right instead of the dot. In short: it is a feature.


Best wishes,
Taco

You are right and I should not expect something sensible from  
number=no, but for my curiosity one question remains: why does \at  
gives a number that should not exist?

Anyway, it is not a problem anymore!

"\in [key]" gives the running number of float, this means 1 for the
first figure,
2 for the second ... This did only work with numbered figures, you disabled
the number in your figure and got only the dummy sign (the bullet) because
there was no number to be shown.

"\at [key]" give you the pagenumber, where your figure was placed and this
was in your example the first page.

Wolfgang

Thanks, this completely satisfies my curiosity.
