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
