guix's code seem to hard for me, I use a emacs command to solve my
problem:
-----------------
(defvar guix-export-directory "~/myguix/")
(defun guix-export-package ()
(interactive)
(let* ((directory (file-name-as-directory guix-export-directory))
(current-module (guix-guile-current-module))
(define-public-string
(save-excursion
(end-of-defun)
(let ((end (point)))
(beginning-of-defun)
(buffer-substring (point) end))))
(package-name
(progn (string-match "\\(define-public +\\)\\([a-z-]+\\)\n+"
define-public-string)
(match-string 2 define-public-string)))
(define-module-string
(replace-regexp-in-string
" *(define-module.*\n"
(format (concat "(define-module (%s)\n"
" #:use-module %s\n")
package-name current-module)
(save-excursion
(goto-char (point-min))
(search-forward "(define-module")
(end-of-defun)
(let ((end (point)))
(beginning-of-defun)
(buffer-substring (point) end)))))
(command (format "guix package --load-path='%s' -i %s "
directory package-name)))
(unless (file-directory-p directory)
(make-directory directory t))
(with-temp-buffer
(insert define-module-string)
(insert "\n")
(insert define-public-string)
(write-file (concat directory package-name ".scm"))
(kill-new command)
(message command)))
