Chapter number retrieval

Chapter number retrieval

[Willi Egger via ntg-context]

Hello everybody!


I would like to typeset the chapter title without number in the text. — However I still would need to retrieve the number for a calculation in a MetaFun graphic. I assume, that even though this number is not typeset, it is kept in the background. How to retrieve it?

Kind regards

Willi

Willi,

I see a comment by yourself back in 2011 at 
https://wiki.contextgarden.net/Last_Head_Number

I wonder if this helps?

Hi Julian,

:-) I am confronted with my own comments :-)

However, this is precisely what I am using in my attempt to get this hidden number. But no it does not appear…

Thank you!
Willi

Re: Chapter number retrieval

[jbf via ntg-context]

Willi, offlist: Have to admit I didn't actually try your own comment, 
but if it doesn't work, I'll be interested in the eventual answer. I 
recently had to do something similar for the TOC, and Hraban pointed me 
to \currentlistentrynumber. There probably has to be a command along 
those lines (which led me to your 2011 comment, sorry 😁) for non-list 
retrieval. \structurenumber? \currentstructurenumber? Something along 
those lines? There seem to be a number of these but as yet undocumented 
as far as I can see.

Hi,

There is a good overview of accessible variables at:
https://tex.stackexchange.com/questions/134474/context-part-chapter-section-and-subsection-names

Maybe you want something like this?

\starttext
\setuphead[chapter][number=no]
\startchapter[title={My Chapter}]
Hello world!
\startMPcode
label("\currentstructurelistnumber\ \currentstructuretitle", origin);
draw fullcircle scaled 3cm;
\stopMPcode
\stopchapter
\stoptext

Hi,

You can define a custom command for the chapter, where the first argument (i.e, the number) is 'ignored' –

  \define[2]\ChapterTitle{#2}
  \setuphead[chapter][command=\ChapterTitle]

It will still appeared as numbered in any lists (ToC, etc). Also, it can be accessed using \headnumber[...][...]. An example graphic – 

  \startuseMPgraphic {graphic:chapter}
  picture cg;
  cg := outlinetext.d
        ("\ssbfd \headnumber[chapter]")
        (withcolor transparent(1,0.5,blue));
  fill boundingcircle cg withcolor transparent(1, 0.5, lightgray);
  draw cg;
  \stopuseMPgraphic

Using \headnumber[..][..] any 'conversion' applied to the chapter number (romannumerals, words, etc) are also preserved.

Best,
Sreeram

Hello Sreeram!

What a nice and simple solution. After fiddling a bit I got it working also in my environment for the book! — Thank you so much for the support.

Re: Chapter number retrieval

Hello Adam!

Many thanks for your solution. — It works very well in your example and also in an extended version with \startfrontmatter..\stopfrontmatter \startbodymatter…\stopbodymatter. — Unfortunately It does not work to my wish in the actual setup of my book. — I am using now the solution presented by Sreeram.

Again thank you so much!
Kind regards

Hi Willi,

You could also access the number by using the
\getmarking[chapternumber][current].
I think you have used a similar approach in the
https://wiki.contextgarden.net/Thumb_index.

Re: Chapter number retrieval

[Willi Egger via ntg-context]

Hello Adam,


What I am actually using (at least basically) is the code given in the second example on the wiki. So this moving graphic is not the problem. The problem lays in the fact, that I need the chapter number for calculating the position of the graphic along the outer edge of the page. — Because the book in question is a dictionary, it is not nice to have the chapter titles numbered, because it is only the letter of the alphabet. If I turned off the numbering, I lost the possibility to retrieve the chapter number. Through the definition of a new command \ChapterTitle, ignoring the first argument (which is the number) the title gets typeset without the number, but the number is still available in the TOC or as in my case for the calculation.

Thank you for your support and help!

Willi
