But entering a command -;; console popup does limit the selection to the commands defined for -;; that popup, and so we use the term "infix" instead of "prefix". - -;;; Code: - -(require 'button) -(require 'cl-lib) -(require 'dash) -(require 'format-spec) -(eval-when-compile (require 'subr-x)) - -(and (require 'async-bytecomp nil t) - (cl-intersection '(all magit) - (bound-and-true-p async-bytecomp-allowed-packages)) - (fboundp 'async-bytecomp-package-mode) - (async-bytecomp-package-mode 1)) - -(declare-function info 'info) -(declare-function Man-find-section 'man) -(declare-function Man-next-section 'man) - -;; For branch actions. -(declare-function magit-branch-set-face 'magit-git) - -;;; Settings -;;;; Custom Groups - -(defgroup magit-popup nil - "Infix arguments with a popup as feedback." - :link '(info-link "(magit-popup)") - :group 'bindings) - -(defgroup magit-popup-faces nil - "Faces used by Magit-Popup." - :group 'magit-popup) - -;;;; Custom Options - -(defcustom magit-popup-display-buffer-action '((display-buffer-below-selected)) - "The action used to display a popup buffer. - -Popup buffers are displayed using `display-buffer' with the value -of this option as ACTION argument.
