(require 'evil)
|
|
(require 'helm-files) ; TODO: Check if this is the ideal requirement and if we are not loading too much.
|
|
|
|
;; To navigate Helm entries with <hjkl> in insert state, we need a modifier.
|
|
;; Using the C- modifier would conflict with the help prefix "C-h". So we use
|
|
;; M- prefixed bindings instead.
|
|
|
|
;; Helm-find-files: We cannot use "h" and "l" in normal state to navigate up and
|
|
;; down the file system hierarchy since we need them to use it to edit the
|
|
;; minibuffer content.
|
|
|
|
(defun evil-helm-setup ()
|
|
;; TODO: We should not modify helm-map in Emacs state but somehow it does not
|
|
;; work otherwise.
