Hello:
In 'The Perfect Setup', we suggest user to use the below emacs config:
```
;; Assuming the Guix checkout is in ~/src/guix.
(with-eval-after-load 'geiser-guile
(add-to-list 'geiser-guile-load-path "~/src/guix"))
```
This config need user to deal with %load-path of guix, which seem to be
a hard job for new guile user for many dirs of guix and other guix channels,
why not suggest new user to use the below config:
```
(setq geiser-guile-binary (list "guix" "repl"))
```
or:
```
(setq geiser-guile-binary (list "guix" "repl" "-L"
"/path/to/user-own-config-dir"))
```
when user just want to develop his own guix config, just run:
```
emacs
```
guix and other channels installed by 'guix pull' will be used properly.
when user want to develop in guix.git, he just run emacs like the below:
```
./pre-inst-env emacs
```
The below is my guix emacs config, seem to work:
--------------------------------------------------------------------------------
(require 'geiser)
(require 'geiser-guile)
(require 'guix)
(require 'magit)
;; ** My own guix config.
(defvar eh-geeguix-dir (expand-file-name "~/geeguix"))
;; ** Let geiser-guile use 'guix repl'
(setq geiser-guile-binary (list "guix" "repl" "-L" eh-geeguix-dir))
;; ** guix-devel-mode
(add-hook 'scheme-mode-hook #'guix-devel-mode)
;; ** Get guix dir installed by 'guix pull'.
(defun eh-guix-dir ()
(file-name-as-directory
(cl-find-if
(lambda (dir)
(file-exists-p (expand-file-name "guix.scm" dir)))
(directory-files
(expand-file-name "~/.cache/guix/checkouts/")
t))))
;; ** copyright-update
(when (eh-guix-dir)
(let* ((dir (eh-guix-dir))
(file (expand-file-name "etc/copyright.el" dir)))
(when (file-exists-p file)
(load-file file)
;; (add-hook 'after-save-hook 'copyright-update)
(setq copyright-names-regexp
(format "%s <%s>" user-full-name user-mail-address)))))
;; ** tempel
(when (eh-guix-dir)
(let* ((dir (eh-guix-dir))
(path (expand-file-name "etc/snippets/tempel/*" dir)))
(add-to-list 'tempel-path path)))
