Dear list,
I have an error when I try to insert a block inside a conditional mode (but
there is two nested conditional mode.. is this the problem ?).
In my courses notes, I insert some blocks (named « Complement » in the minimal
exemple below) when in « Professor » mode. This works fine, as shown in the
first « \beginComplement … \endComplement » of my example below.
But now I have to use another condition for some blocks, depending of the
number of the current course. So I insert my block with a condition, here «
CourseOne » :
\enablemode[CourseOne]
\doifmode{CourseOne}{
\beginComplement
Another complementary slide.
\endComplement
}
But this does not work :

The problem can be summarized in this minimal non working example :

\doifmode{CourseTwo}{
\beginComplement
Another complementary slide but only for course number 2.
\endComplement

Blocks and modes usually works fine for me, but here, I do not understand my
error.
Thanks for any help !
Fabrice.
Note : in case this way of doing things seems a bit silly, here are more
explanations. I do use mode « CourseOne » here because in the real life, the
content in the condition « \doifmode{CourseOne}{ …} » is read in an external
file, containing material for « CourseOne », « CourseTwo », etc. The setup is
then, in the main file :
% Main file : begin ----------------
Bla bla bla ...
\enablemode[CourseOne]
\input ComplementMaterial.tex
\disablemode[CourseOne]
Bla bla bla ...
\enablemode[CourseOne]
\input ComplementMaterial.tex
\disablemode[CourseOne]
% Main file : end ----------------
And in the « ComplementMaterial.tex » there is :
% ComplementMaterial.tex —————————
\doifmode{CourseOne}{
\beginComplement
A complementary slide but only for course number 1.
\endComplement
\beginComplement
Another complementary slide but only for course number 1.
\endComplement
}
\doifmode{CourseTwo}{
\beginComplement
A complementary slide but only for course number 2.
\endComplement
\beginComplement
Another complementary slide but only for course number 2.
\endComplement
}
% ComplementMaterial.tex —————————
