  ;; will be highlighed with `diff-removed` face which is typically
  ;; some red color (as defined by the color theme)
  ;; other faces such as `diff-added` will be used for other actions
  (evil-goggles-use-diff-faces))

without use-package from Melpa

Customizations

Appearance Customization

• To pulse the visual hint, rather than just show and hide it:

(setq evil-goggles-pulse t) ;; default is to pulse when running in a graphic display

• To change the default face:

(custom-set-faces
 '(evil-goggles-default-face ((t (:inherit 'highlight))))) ;; default is to inherit 'region
;; run `M-x list-faces-display` in a fresh emacs to get a list of faces on your emacs

By default, all goggles' faces inherit evil-goggles-default-face, which in turn inherits emacs' region face.

• To use different faces per edit action:

(custom-set-faces
 '(evil-goggles-delete-face ((t (:inherit 'shadow))))
 '(evil-goggles-paste-face ((t (:inherit 'lazy-highlight))))
 '(evil-goggles-yank-face ((t (:inherit 'isearch-fail)))))

• The following faces are defined by evil-goggles:

evil-goggles-default-face - inherits from `region` by default

evil-goggles-delete-face - this, and the others below, inherit from `evil-goggles-default-face`
evil-goggles-change-face
evil-goggles-indent-face
evil-goggles-yank-face
evil-goggles-join-face
evil-goggles-fill-and-move-face
evil-goggles-paste-face
evil-goggles-shift-face
evil-goggles-surround-face
evil-goggles-commentary-face
evil-goggles-nerd-commenter-face
evil-goggles-replace-with-register-face
evil-goggles-set-marker-face
evil-goggles-undo-redo-add-face
evil-goggles-undo-redo-remove-face
evil-goggles-undo-redo-change-face
evil-goggles-record-macro-face

Other Customizations

• The duration of the overlay is configured with evil-goggles-duration:

(setq evil-goggles-duration 0.100) ;; default is 0.200

• For more fine grained duration configuration, these can be modified:

;; this variable affects "blocking" hints, for example when deleting - the hint is displayed,
;; the deletion is delayed (blocked) until the hint disappers, then the hint is removed and the
;; deletion executed; it makes sense to have this duration short
(setq evil-goggles-blocking-duration 0.100) ;; default is nil, i.e. use `evil-goggles-duration'

;; this variable affects "async" hints, for example when indenting - the indentation
;; is performed with the hint visible, i.e. the hint is displayed, the action (indent) is
;; executed (asynchronous), then the hint is removed, highlighting the result of the indentation
(setq evil-goggles-async-duration 0.900) ;; default is nil, i.e. use `evil-goggles-duration'

• To disable the hint on certain actions modify these variable before evil-goggles-mode is started:

;; to disable the hint when pasting:
(setq evil-goggles-enable-paste nil)

;; list of all on/off variables, their default value is `t`:
;;
;; evil-goggles-enable-delete
;; evil-goggles-enable-change
;; evil-goggles-enable-indent
;; evil-goggles-enable-yank
;; evil-goggles-enable-join
;; evil-goggles-enable-fill-and-move
;; evil-goggles-enable-paste
;; evil-goggles-enable-shift
;; evil-goggles-enable-surround
;; evil-goggles-enable-commentary
;; evil-goggles-enable-nerd-commenter
;; evil-goggles-enable-replace-with-register
;; evil-goggles-enable-set-marker
;; evil-goggles-enable-undo
;; evil-goggles-enable-redo
;; evil-goggles-enable-record-macro
