|Subject:||Help porting someone else's macro from 4 to 5.|
|Date:||Mon, 20 Jan 2020 22:02:56 -0500|
Hello all, I'm attempting to port the sdl-mixer egg (originally by Christian Kellermann) from 4 to 5. I think I've made most of the necessary changes, but I'm running into a bit of an issue and would greatly appreciate some help troubleshooting.
I'm a bit new to Chicken and lisp in general, and while I feel I have a decent understanding of regular macros the er- and ir-macro-transformer procedures are still eluding me somewhat. In sdl-mixer's chicken 4 source, we have the macro
) ; end module
Looking through various chicken documentation, my first assumption was to wrap the lambda argument to define-syntax in an er-macro-transformer call. However this does not recognize append-map (of course defined in srfi-1) as bound. I thought that it might also need to be renamed with (r 'append-map) but this also did not work.
Since I am new to Chicken, I assume its a misunderstanding on my part of what is necessary, but I cannot figure out where to go from here. So first of all, is my assumption that I need an er-macro-transformer correct, or am I barking up the wrong tree? Second, after resolving the first question what is the next step I need to take? Any help would be greatly appreciated.
Thanks in advance,
