Hi Hans,

(2) Another change is in the \startdocument mechanism. This (already
old and rusted) wrapper runs on top of variables but we think no one
knows (or uses) that. So, it now is a real wrapper with inheritance
and such. It is dedicated to Tomas Hala who had to struggle with the
old one but still gave a presentation using it. Here's an example:
\definedocument[thesis]
\setupdocument[a=b,e=f]
\setupdocument[thesis][a=x,c=d]
\startsetups[document:start]
START
\stopsetups
\startsetups[thesis:stop]
STOP
\stopsetups
\startthesis
(\currentdocument/a): \documentvariable{a}\par
(\currentdocument/c): \documentvariable{c}\par
(\currentdocument/e): \documentvariable{e}\par
\stopthesis
The auto-inheritance of the setups does not work yet, because the
\definedocument[thesis] does not
set up local version of the before= and after= keys of \startthesis.
\definedocument (re)defines the value of the actual setup
“thesis:start” correctly to inherit the
parent’s \directsetuo, but because the actual before and after keys
are inherited from the (document)
parent as well, the effect on \startthesis still remains equivalent to
this:
\setupdocument
[thesis]
[before=\directsetup{document:start},
after=\directsetup{document:stop}]
So we need something like this:
\appendtoks
\setexpandeddocumentparameter\c!before{\noexpand\directsetup{\currentdocument:\v!start}}%
\setexpandeddocumentparameter\c!after
{\noexpand\directsetup{\currentdocument:\v!stop }}%
\to \everydefinedocument
the reason i didn't make setups inheritable was mostly that I can't
oversee the intensions (i played a bit with it; like defining setups as
part of define so that we can have inherited setups) ... for instance
what when we have a third level (say document -> thesis -> mythesis ..
and we want to use the thesis setups)
i don't care what solution si chose as long as it doesn't break anything
at my end
