For whats it worth at least we can safely say it with how sockets (at least in for guile) handle gexp.

I only came to that conclusion because I loaded my own [default] geiser repl with emacs-guix mode, and comparing that to the emacs-guix repl that loads automatically. > In the error message, there is a mention of "#~".

Very cool that you found this. I would love to test this out, is there any formal way to apply this and have emacs point to the test guix?

Im certain it's not anyone procedure, but rather the internal repl being in a socket file. I dont know how guile is handling sockets, but guile (socketed) cant read '#' for some reason. The next step might be going to the guile mailing list and getting some answers there, cause guile has nil for documentation and I have come up empty handed in looking for any answers for guile socket files. Either way, I think emacs-guix is important enough to get this fix, so will do. Stay safe, -Joshua ^ permalink raw reply [flat|nested] 7+ messages in thread
