Re: [NTG-context] Conditional text appearing in a fixed vertical space
You can also consider using viewerlayer:
\setupinteraction[state=start]
\defineviewerlayer[solution]
\setupcolors[state=start]
\usecolors[xwi]
\definecolor[keyColor][1.0(maroon)]
\starttext
\startitemize[n]
\but[ToggleLayer{solution}]
\samplefile{tufte}
\blank[big]
\startviewerlayer[solution]
\keyColor
\samplefile{knuth}
\stopviewerlayer
\stopitemize
\stoptext
I print the file with the solution layer off to a 'clean' file for students.

Re: [NTG-context] Conditional text appearing in a fixed vertical space
Thanks Fabrice and Aditya!
With three completely different approaches, I learned three times more than I
was expecting. This has been a great help. I will probably use the framedtext
method, but I learned something from each.

This is how I would do it: piggyback on framedtext. Note that framedtext
doesn't break across pages. So, if you have long answers, a different mechanism
is needed.
\definemode[solution][no]
\doifmodeelse{solution}
{\defineframedtext[solution][empty=no]}
{\defineframedtext[solution][empty=yes]}
% Doesn't work. Why?
% \expanded{\defineframedtext[solution][empty=\doifmodeelse{solution}{no}{yes}]}
\setupframedtext
[solution]
[
spacebefore=medium,
spaceafter=medium,
width=broad,
foregroundstyle=\rm\it,
loffset=2em,
roffset=2em,
indentnext=no,
]
\starttext
Sample question. Always show answer.
\startsolution[height=1in, empty=no]
Alotta wood!
\stopsolution
How much wood?
\startsolution[height=1in]
Alotta wood!
\stopsolution
You don't need to specify the height:
\startsolution
\input ward
\stopsolution
No more questions.

I have similar problem for my courses. The solution I use, different than the
one offered, is to write in a « special » color the text I want to hide from
the students. This permits me to have hidden texts in figures for exemple.
Also, I do not calculate space required, this is automated ! Here is MWE :
\enablemode[solution]
\doifmode{solution}{
\definecolor[solcolor][magenta]
}
\doifnotmode{solution}{
\definecolor[solcolor][white]
}
\definedescription[solution]
[color=solcolor]
\starttext
How many roads? \startcolor[solcolor] Professor note.\stopcolor
\startsolution
42 roads.
\stopsolution
How much wood?
\startsolution
Alotta wood!
\stopsolution
No more questions.
\stoptext
So the color used when solutions are hidden are white on white, we can not see
the text; but of course, if you change the background, you see the hidden
text. So there is another step to the process (I usually do this only once a
term); open the file in Acrobat, and find the option to delete hidden text. The
text for which the color is the same as the background is really deleted. You
can try to select the text in any pdf view/editor, the text is gone !

Re: [NTG-context] Conditional text appearing in a fixed vertical space
Thanks Hans! This is great. I made a slight change to add an additional
feature. By moving the “mysolution” definition out of \startmode[solution], I
can now use mysolution in either mode. I’d use this if I want to give my
solution to one of the problems, as an example, on the handout.

[NTG-context] Conditional text appearing in a fixed vertical space
Hello List,
I am making problem sets for a physics class. Solutions use the style defined
in the example below, and only appear if the “solution” mode is enabled. I am
struggling to get a vertical space for the solution which is the same whether
or not the solution is printed. Different problems require different amounts of
space, so this should be an argument or key-value.
In the example below, the first solution has the desired behavior. The second
solution has the syntax I’d like, but it doesn’t make the space without a
solution.
Any ideas would be welcome! I am still pretty new to ConTeXt, so I struggle
mixing things like the plain tex \vbox and ConTeXt \start…\stop concepts.
Thanks,
Gavin
