Setting Racket Geiser Emacs Path

Question

I\'m trying to get Geiser\'s REPL to work in Emacs, but it doesn\'t seem to be able to find Racket.

racket is on my path, but anytime I type

Answer 1

I know this is an old question, but for future people having a hard time getting it to find the Racket executable despite it being in your path, you can simply use the executable-find function.

This searches your path and returns the absolute path to the executable, which is what the geiser-racket-binary function wants. So this is an alternative to explicitly setting the absolute path:

(setq geiser-racket-binary (executable-find "Racket"))

Answer 2

Ok, so I added:

(setq geiser-racket-binary "/home/user/racket/bin/racket")

to my .emacs file after loading geiser.el.

I was expecting a configuration file somewhere to set this.

Thanks.

Answer 3

In Windows, adding the location of the Racket executable to the "path" environment variable which is part of Windows will allow Geiser/Emacs to find the Racket Executable.
