As I explained before, whenever a TOC item appears in the source file before
the actual TOC the whole TOC becomes blank. This is true whether the item is
a chapter and included automatically or I use the "write" commands to do it
manually. Here is a dummy file:
\pdfoutput=1
\starttext
\chapter{foo}
\completecontent
\chapter{bar}
\stoptext
When I run the above file the TOC will have a header but no contents. If
however I comment out \chapter{foo}
then chapter bar appears in the contents.
I have also tried the write etc. commands and if they appear before the
\completecontent
command then the TOC blanks out.
This may be a function of The general TeX procedure to write out the items on
one pass and bring them in on the next. The write to \chapter{foo} may
reinitialize the external file when it is encountered on the second pass.
According to the TeXbook the write occurs when the page is shipped out. So
\chapter{foo} probalbly clobbers the external file. Still the TOC mechanism
should be developed in a way that it is possible to incorporate items
occurring before the TOC in the TOC. This is not an uncommon requirement.
A cure might be to move the external file to a different file name at the end
of each pass in texexec, and bring in that copy of the file instead of the
original external file to create the actual TOC.. That way any premature
references would not go to the copy but to a new original. Pehaps Hans could
rewrite the texexec or the Content macros themselves to do this. In
pseudocode of sorts it would work like this:
\starttext
\chapter{foo} =write to filea
\placecontent= read from fileb
\chapter{bar}=write to filea
\chapter{alpha}=write to filea
(etc.)
\stoptext.
copy filea to fileb
end
