[Geiser-users] Which Scheme implementation is Geiser using?

[Deokhwan Kim]

Hi all,

Does Geiser provide a public API that tells us which Scheme implementation
Geiser is associating the current buffer with? I have found the
`geiser-impl--implementation` variable but it looks like a private variable.

I am trying to figure out how to turn on Flycheck's Racket syntax checker only
when Geiser is using Racket: https://github.com/flycheck/flycheck/pull/979

Thanks,
Deokhwan Kim
