how can I check whether a macro I defined is actually expanded into
what I intended? For example, if I define
\define[2]\Test{#2, {\it #1}}
is there a (Lua?) function like
check(\Test{Hello}{world}, string)
that would return true for string = "world, {\it Hello}" and false
otherwise? If the macro is a bit more complicated than this I
usually get caught by a mistake rather quickly ... so a quick check
would be very handy for me.
You can check the content in ConTeXt itself.
\define[2]\Test
{\doifelse{#1}{world}{\writedirect{Test \#1: true}}
{\writedirect{Test \#1: false}}%
\doifelse{#2}{Hello}{\writedirect{Test \#2: true}}
{\writedirect{Test \#2: false}}%
#2, {\it#1}}
This is perfect if the arguments of \Test are fixed once and for all.
But actually I'd like to get something different ... (perhaps I
shouldn't have called the macro \Test but rather
\MyMysteriousMacro :-). Suppose I know what the output of this macro
(after expansion) should yield for *various* inputs. Now I just want
to check whether the macro really does what I expect it to do. For
example:
bool1 = check(\MyMysteriousMacro{Hello}{world}, "world, {\it Hello}")
bool2 = check(\MyMysteriousMacro{Wolfgang}{How are you}, "How are you,
{\it Wolfgang}")
etc.
Usually the macro would typeset something but here I'd just like this
comparison with the supplied string (without anything ending up on
paper).
How would I do that?
Many thanks,
Oliver
