No problem, you can even dynamically add an option available only when a grep program is installed: (defcustom grep-program nil "The default grep program for `grep-command' and `grep-find-command'. This variable's value takes effect when `grep-compute-defaults' is called." :type `(choice (const :tag "GNU grep" (purecopy "grep")) ,@(if (executable-find "rg") '((const :tag "ripgrep" "rg"))) (string :tag "Other grep program") (const :tag "Not Set" nil)) :version "28.1") Or for a completely new tool: (nconc (get 'grep-program 'custom-type) '((const :tag "ripgrep" "rg")))
