cross references to chapters in a book

cross references to chapters in a book

[Robert Zydenbos]

Dear wizards of ConTeXt,

In the final stage of completing a book project, I was wondering how to automatize cross references to chapters. I’ve already figured out how to refer to pages (using “\at[REFERENCE]”), but how is this done with chapters? I’m apparently too simple-minded to understand the manual (and I don’t understand the differences between \reference, \textreference, \in, \about).

Robert

When you use \chapter:

\starttext

\chapter[sec:knuth]{Knuth}

\samplefile{knuth}

See \in{chapter}[sec:zapf] at \at{page}[sec:zapf].

\chapter[sec:zapf]{Zapf}

\samplefile{zapf}

See \in{chapter}[sec:knuth] at \at{page}[sec:knuth].

\stoptext


When you use \startchapter:

\starttext

\startchapter[title={Knuth},reference={sec:knuth}]

\samplefile{knuth}

See \in{chapter}[sec:zapf] at \at{page}[sec:zapf].

\stopchapter

\startchapter[title={Zapf},reference={sec:zapf}]

\samplefile{zapf}

See \in{chapter}[sec:knuth] at \at{page}[sec:knuth].

\stopchapter

\stoptext


Wolfgang

Use \about[sec:knuth], if you need the title.

Re: cross references to chapters in a book

Hmm… although I got your example to work after some tweaking (changing \samplefile to {input and placing knuth.tex and zapf.tex in the same folder as the test file), I could not reproduce this with my book. I want to get "chapter 4" but keep getting "chapter 4.0".

Is this because I am using MkII with XeTeX?

Re: cross references to chapters in a book

Still nicer would be the following, but I do not know whether this is technically possible –

I have the following text:

% start of example: in chapter 4, pp. 38, I have
\subject [wild-stuff]{Wild stuff}
Now comes a lot of weird stuff which I want to refer to later.
…
% end of stuff in one chapter

% in another chapter:
As we already saw in \in{chapter}[wild-stuff], on p.~\at[wild-stuff]
% that was in the other chapter
% end of example

and the result would be: “As we already saw in chapter 4, on p.~38”…

Can such a thing be done?

Robert

You have to create a minimal working example for this because I can’t 
tell why you get this output.

Is there a reason why you stick with MkII or XeTeX.

Can’t you just add a reference to the chapter title and refer to it 
instead of the the subject.

When you goal is to show the value of the chapter for the current 
subject you should switch to MkIV where this can be done (although we 
have to cheat to because we have to create numbered subject’s and hide 
the counter).

Hi Wolfgang,

support for Indic languages seems to be the reason to use MkII.
