The main one (with "guile --listen" process) is used for -;; "interacting" with a user - for showing a progress of -;; installing/deleting Guix packages. The second (internal) REPL is -;; used for synchronous evaluating, e.g. when information about -;; packages/generations should be received for a list/info buffer. -;; -;; This "2 REPLs concept" makes it possible to have a running process of -;; installing/deleting packages and to continue to search/list/get info -;; about other packages at the same time. If you prefer to use a single -;; Guix REPL, do not try to receive any information while there is a -;; running code in the REPL (see -;; ). -;; -;; Guix REPLs (unlike the usual Geiser REPLs) are not added to -;; `geiser-repl--repls' variable, and thus cannot be used for evaluating -;; while editing scm-files. The only purpose of Guix REPLs is to be an -;; intermediate between "Guix/Guile level" and "Emacs interface level". -;; That being said you can still want to use a Guix REPL while hacking -;; auxiliary scheme-files for "guix.el". You can just use -;; `geiser-connect-local' command with `guix-repl-current-socket' to -;; have a usual Geiser REPL with all stuff defined by "guix.el" package. - -;;; Code: - -(require 'geiser-mode) -(require 'geiser-guile) -(require 'guix-geiser) -(require 'guix-config) -(require 'guix-external) -(require 'guix-emacs) -(require 'guix-profiles) - -(defvar guix-load-path guix-config-emacs-interface-directory - "Directory with scheme files for \"guix.el\" package.") - -(defvar guix-helper-file - (expand-file-name "guix-helper.scm" guix-load-path) - "Auxiliary scheme file for loading.") - - -;;;
