last chapter number

last chapter number

[Andreas Harder]

Hi all,

is there already an equivalent to \lastpage for the last chapter number in a document. I tried something like \getmarking[chapternumber][last], but the output is still the current chapter number.

Thanks in advance

	Andreas

can you try \convertedstructurecounter[chapter][type=last]

Hello Wolfgang,

I tried, but it only outputs nothing visible. Here a test file

\starttext
\dorecurse{10}{\chapter{Kapitel #1}
  \tex{getmarking[chapternumber]} = \getmarking[chapternumber] \crlf
  \tex{convertedstructurecounter[chapter][type=last]} =
  \convertedstructurecounter[chapter][type=last] 
}
\stoptext


Greetings
	Andreas

Sorry, my fault. Section numbering use their own system to save and get the numbers.

What you can do is to save the number of the last chapter at the end of the document
with two pass data (\definetwopasslist) and use the result in the second run or you
what for a solution from Hans.

Thank you Wolfgang! You pointed me to \definetwopasslist and that brought me to the following solution (without \definetwopasslist):

\newcounter\ChapNum
\def\NofChaps{0}

\definehead
  [chapter]
  [before=\increment\ChapNum,
    after=\savecurrentvalue\NofChaps{\countervalue{ChapNum}}]

\starttext
Dieses Dokument besteht aus \NofChaps\ Kapiteln.
\dorecurse{9}{\chapter{Kapitel #1}}
\stoptext

Nonetheless the needed information is already present even more if one uses a table of contents …

The table of contents needs two passes too but only Hans can say (or provide
a command like \convertedstructurecounter for section numbers) how you can
access these information.

i'm sure that you can figure it out if needed but i can certainly add 
something

  \convertedstructurecounter[chapter][type=last]

but as

  \convertedstructurecounter[section][type=last]

is ambiguous it needs a bit of thinking, as it more relates to lists 
like criteria then

of course one can use a reference for the last chapter instead

the beta now has

\starttext

\dorecurse {5} {
     \chapter{Test #1}
     first: \somestructureheadnumber[chapter][first]\par
     current: \somestructureheadnumber[chapter][current]\par
     last: \somestructureheadnumber[chapter][last]
     \dorecurse {3} {
     \section{Test #1}
         first: \somestructureheadnumber[section][first]\par
         current: \somestructureheadnumber[section][current]\par
         last: \somestructureheadnumber[section][last]

Thanks a lot!

I’ve wikified your example.

One more question appeared: How to access them in a Metapost environment? I tried some methods but none of them seems to work.

% \setupMPvariables
%   [test]
%   [current={\somestructureheadnumber[chapter][current]},
%    last={\somestructureheadnumber[chapter][last]}]

\startuseMPgraphic{test} 
  current := \somestructureheadnumber[chapter][current] ;
  last    := \somestructureheadnumber[chapter][last]    ;
  % current := 2 ;
  % last    := 6 ;
  
  skip    := TextHeight * (current-1)/last ;
  StartPage ;
    fill fullcircle scaled 3cm shifted (skip,skip) ;
  StopPage ;
\stopuseMPgraphic

\defineoverlay[test][\useMPgraphic{test}]

\setupbackgrounds[page][background=test]

\starttext
\dorecurse{6}{\chapter{Kapitel #1}
  Kapitel \somestructureheadnumber[chapter][current] von
  \somestructureheadnumber[chapter][last] }
\stoptext

Thank you in advance

	Andreas

\somenamedheadnumber{chapter}{current}
