I have now commited support for parametrized macros.
Wow! That was quick! Big thanks from me!
Waldek, I hope you don't mind if I keep asking for things that I would
find useful.
Now having parametrized macros, I can write
rep x ==> (x@%) pretend Rep
per x ==> (x@Rep) pretend %
and that seems to work. At least it compiled one file that uses it.
Naturally, I don't want to repeat these macros in every file. However,
if I replace the two macros in the .spad file by
)read mymacros.input
where mymacros.input just contains the rep+per lines, and then )compile,
I get an output as shown below. I get the same error message as if the
)read line wouldn't be there. Maybe the scope for macros from an input
file is not extended to the calling spad file?
Another issue. Should I be able to group macros like this (in a .spad file)?
macro
rep x == (x@%) pretend Rep
per x == (x@Rep) pretend %
At the moment I get
