First of all thanks for this awesome contribution! I really like
it. I haven't used slime before so maybe my suggestions are no
brainers but here they are:
- Make the swank-chicken.scm file also part of the installation of
the swank egg. Then people can just symlink to it or point their
slimes to the system location
- Use irrgex is needed on my newer chicken to make the egg compile
- Move your fine work over to the egg repository. Then it is more
accessible for chicken users. Mario will gladly give you a repo
directory to store it in.
- Maybe make the location of csi a parameter? It may be a
misconfiguration of my emacs but I needed to include the full path
in chicken-swank.
- With newer chickens csi does have commands to show the local
variables in call-chains, so maybe this can be added. From the swank
introductory video I gathered that this is standard behaviour on
lisps.
I have attached my suggestions as a patch against the git repo.
That's it for now, I will happily test any newer versions of it.
Welcome to the chicken world :)
Kind regards,
Christian
