I'm using the latest ConTeXt reported here, and I'm noticing
that partial contents for the second, third etc part are not
available. I have a bunch of files each of which goes like
\part{some part}
Some text (not always)
\placecontent
\chapter{some chapter}
Each of this file is \input from the master file. However,
only in the first part you actually see the (part-specific)
content: every other part reports
system : part,chapter,section,subsection not found/processed
The setup for the contents is as follows:
\setupcombinedlist[content]
[interaction=all,
partnumber=no,
alternative=c,
level=subsection]
\setuphead[part][alternative=middle,placehead=yes,resetnumber=no]
The problem is the 'resetnumber': if I take that off,
everything works perfectly.
I've been debugging this, and the reason for the thing not
coming up for parts after the first is that when
resetnumber=no the current level is not properly detected:
in one case you get
\currentlevel -:1
in the other
\currentlevel -:2:2:4:2
Which is obviously wrong. Indeed, the problem is here:
\listentry{part}{1}{1}{Introduction}{2::1:0:0:0:0:0:0::7}{8}
\listentry{chapter}{2}{1}{Presentation}{2::1:1:0:0:0:0:0::8}{9}
\listentry{section}{3}{1.1}{History and
motivation}{2::1:1:1:0:0:0:0::8}{9}
\listentry{chapter}{11}{2}{The
basics}{2::1:2:0:0:0:0:0::12}{13}
\listentry{section}{12}{2.1}{Notation}{2::1:2:1:0:0:0:0::12}{13}
(more stuff)
\listentry{subsection}{78}{2.4.2}{Scaling the
coordinate system}{2::1:2:4:2:0:0:0::31}{32}
\listentry{part}{79}{2}{Mathematical
tools}{2::2:2:4:2:0:0:0::34}{35}
\listentry{chapter}{82}{3}{Bézier cubic
analysis}{2::2:3:0:0:0:0:0::35}{36}
OOOPSIE! Since resetnumber=no, the listentry keeps the old
settings for chapter, section the like. This is obviously
wrong. Even if the number is not reset, the sectionformat
*must* be reset, since at the beginning of the new
higher section(level) you are not in the previous one
anymore. So for example when starting a new part (with
resetnumber=no), and until
the first chapter of the new part is started we are in
chapter 0 for that part, not in chapter
'last-chapter-from-previous-part'.
Can this be fixed?
Ok, I came up with a solution that seems to work:
\def\definesection[#1]%
{\doifundefined{\??se#1}
{\doifelsenothing\firstsection
{\def\firstsection{#1}%
\setevalue{\??se#1\c!before}{\v!text}%
\setevalue{\??se\v!text\c!after}{#1}}
{\setevalue{\??se\commalistelement\c!after}{#1}%
\setevalue{\??se#1\c!before}{\lastsection}%
\setevalue{\??se\lastsection\c!after}{#1}}%
\advance\nofsections \plusone
\setevalue{\??se#1\c!level}{\the\nofsections}%
\letvalue{\??se#1\c!after}\empty
\setvalue{\e!next#1}{\@@nextsectionnumber{#1}}%
\setvalue{#1\c!number}{\@@longsectionnumber{#1}}%
\setvalue{#1\s!format}{\@@longformatnumber{#1}}%
\setevalue{\??by#1}{#1}%
\setevalue{\??by\v!by#1}{#1}%
\makecounter{\??se#1}%
\makecounter{\??se lastvalueof#1}% GB
\edef\lastsection{#1}%
\setvalue{\??sk#1}{#1}%
\letvalue{\??se#1\c!marking}\empty
\setupsection[#1][\c!previousnumber=\v!yes]}}%
% New command preserves the value of the next sectionlevel
% when resetnumber=no
\def\checkpreservevalueafter#1%
{\ifnum\getvalue{\??se#1\c!level}\the\nofsections
\edef\preservedsection{\getvalue{\??se#1\c!after}}%
\ifconditional\@@resetsubheadnumbers
\setcounter{\??se lastvalueof\preservedsection}%
{0}%
\else
\setcounter{\??se lastvalueof\preservedsection}%
{\countervalue{\??se\preservedsection}}%
\fi
\fi}
\def\@@setsectionnumber#1#2%
{\letgvalueempty{\??se#1\s!start}% signal i.p.v. boolean
\setcounter{\??se#1}{#2}%
\checkpreservevalueafter{#1}
\resetsectioncounters{#1}
\checkpagecounter}
\def\@@nextsectionnumber#1%
{\letgvalueempty{\??se#1\s!start}% signal i.p.v. boolean
\ifnum\countervalue{\??se lastvalueof#1}\zerocount
\setcounter{\??se#1}{\countervalue{\??se lastvalueof#1}}
\setcounter{\??se lastvalueof#1}{0}
\fi
\pluscounter{\??se#1}%
\checkpreservevalueafter{#1}
\resetsectioncounters{#1}
\checkpagecounter}
This has been tested in a fairly complex document (some
levels with resetnumber=no, some with the usual resetnumber;
sectionblocks etc). It works, and fixes the placecontent not
working. Will this go into mainline?
