[Geiser-users] Macro stepper?

[Dmitry Pavlov]

Hello,

I recently started to program in Racket, and I like Geiser very much.
However, there is a feature DrRacket has that I miss in Geiser:
the Macro Stepper.

I have a custom (non-sexp) language, for which I provide #lang mylang
declaration in my module. Compilation works well, but I actually
need to see how the code in my language expands into Racket macro
forms. DrRacket's "Macro Stepper" button does that perfectly.
Is there something similar for Geiser?

I tried to select the entire buffer and perform Geiser's
"macroexpand region", but it does not work, saying:

  Error: retort-syntax

  UNKNOWN::19310: read: #lang not enabled in the current context


Best regards,

Dmitry
