I do not understand your point.  ’guix-eval-in-repl’ is a wrapper around
’geiser-repl--send’ so it uses Geiser, isn’t it?

From my understanding, the culprit of Emacs hanging when building seems
more something wrong with the current implementation in Emacs-Guix than
really Geiser.

It reads:

    (guix-eval-in-repl
     (format (concat "(build-package* (package-by-id %d)"
                     " #:use-substitutes? %s"
                     " #:dry-run? %s)")

where ’build-packages*’ reads:

--8<---------------cut here---------------start------------->8---
(define (build-package* package . build-options)
  "Build PACKAGE using BUILD-OPTIONS acceptable by 'set-build-options'.
Show what and how will/would be built."
  (with-store store
    (run-with-store store
      (apply build-package package build-options))))
--8<---------------cut here---------------end--------------->8---

Especially if

     (guix-eval-in-repl
       "(guix-build \"nyxt\" \"--no-grafts\" \"--check\")")

works fine.


All the best,
simon

What do you name Geiser?
