I am not sure how to translate this use-package :commands syntax into a regular elisp init.el file.

(use-package languagetool :commands (languagetool-check languagetool-clear-suggestions languagetool-correct-at-point languagetool-correct-buffer languagetool-set-language languagetool-server-mode languagetool-server-start languagetool-server-stop))

I just tried to evalute them as functions, like so.

(languagetool-check) (languagetool-clear-suggestions) (languagetool-correct-at-point) (languagetool-correct-buffer) (languagetool-set-language) (languagetool-server-mode) (languagetool-server-start) (languagetool-server-stop)

But that throws an error Wrong number of arguments: languagetool-check, 0.

  • C-h f language-tool-check should tell you what arguments it requires. You've provided no arguments. Commented Dec 23, 2022 at 18:23

The main use of use-package is to delay loading (i.e. require) of the package until it is needed.

The :command syntax is to provide a list of functions to autoload, so that if they are called, the call will force the loading of the package.

So you don't need them if you are controlling the loading of the package in other ways.

You just need (require 'languagetool) before calling one of the listed functions.

To see what use-package does just expand it using macroexpand:

(pp (macroexpand '(use-package languagetool :commands (languagetool-check languagetool-clear-suggestions languagetool-correct-at-point languagetool-correct-buffer languagetool-set-language languagetool-server-mode languagetool-server-start languagetool-server-stop)))) ===> (progn (defvar use-package--warning1 #'(lambda (keyword err) (let ((msg (format "%s/%s: %s" 'languagetool keyword (error-message-string err)))) (display-warning 'use-package msg :error)))) (condition-case-unless-debug err (progn (unless (fboundp 'languagetool-check) (autoload #'languagetool-check "languagetool" nil t)) (unless (fboundp 'languagetool-clear-suggestions) (autoload #'languagetool-clear-suggestions "languagetool" nil t)) (unless (fboundp 'languagetool-correct-at-point) (autoload #'languagetool-correct-at-point "languagetool" nil t)) (unless (fboundp 'languagetool-correct-buffer) (autoload #'languagetool-correct-buffer "languagetool" nil t)) (unless (fboundp 'languagetool-set-language) (autoload #'languagetool-set-language "languagetool" nil t)) (unless (fboundp 'languagetool-server-mode) (autoload #'languagetool-server-mode "languagetool" nil t)) (unless (fboundp 'languagetool-server-start) (autoload #'languagetool-server-start "languagetool" nil t)) (unless (fboundp 'languagetool-server-stop) (autoload #'languagetool-server-stop "languagetool" nil t))) (error (funcall use-package--warning1 :catch err))))

use-package is now part of emacs 29 and even before it was easily loaded so I don't see why it can't be in a regular init.el.
