According to the wiki, we cannot nest several \startmode …\stopmode, but there
is no limitation with \doifmode.

Following your advice, I tried with several {}, but no luck.

I already use blocks, but following your message, I tried to think differently.
One solution would be to define a block for each course. Something like this (a
working minimal example, redone in order this would be more easier to
understand (I hope!) what I’m trying to do):
% —————————————
\setuppapersize[S5][S5]
\enablemode[Professor]
\defineblock[ComplementTwo]
\defineblock[ComplementThree]
\setupblock[ComplementTwo,ComplementThree][
before={\page[yes]\setuppagenumber[state=stop]\setupheadertexts[]\setupbackgrounds[page][background=color,backgroundcolor=red]},
after={\page[yes]\setuppagenumber[state=start]}]
\starttext
% Let's process the summaries ;
\beginComplementTwo
Last course, we have seen A.
\endComplementTwo
\beginComplementThree
Last course, we have seen B….
\endComplementThree
\beginComplementThree
Last course, we have seen C….
\endComplementThree
% ----
Let's begin course 1.
This is course 1 : a lot of pages here about A!
\page[yes]
Let's begin course 2.
\doifmode{Professor} {
\useblocks[ComplementTwo]
}
This is course 2 : a lot of pages here about B and C!
\page[yes]
Let's begin course 3.
\doifmode{Professor} {
\useblocks[ComplementThree]
}
This is course 3 : a lot of pages here about D... !
\stoptext
%—————————
The only inconvenient of this solution if that I have to define 15 blocks (one
for each week of the term): ComplementOne, ComplementTwo, ..,
ComplementFithteen… Another drawback of this is difficult to move one block
form one week to another if I change something. Each block here correspond in
fact to a summary of the previous course. So I have typically around 10 pages
of summary for each course. The challenge is that the content of each course is
not exactly the same form one term to another, so I have to move a page to the
summary from one course to the other one, like in a given term, if teach about
subject C in course 3 :
\beginComplementThree
Last course, we have seen C….
\endComplementThree
, but next term in course 4:
\beginComplementFour
Last course, we have seen C….
\\beginComplementFour
I have to manually change \beginComplementThree … \endComplementThree to
\beginComplementFour … \beginComplementFour.
But I will do this if I do not find another solution.
Thanks again Hraban.
Fabrice.
