;; Evil bindings for the minibuffer.
;;; Code:
(require 'evil)
(defun evil-collection-minibuffer-insert ()
"Switch to insert state.
This function is meant to be hooked in the minibuffer:
(add-hook 'minibuffer-setup-hook 'evil-collection-minibuffer-insert)
`evil-set-initial-state' can not be used for the minibuffer since
it does not have a mode."
(set (make-local-variable 'evil-echo-state) nil)
;; (evil-set-initial-state 'mode 'insert) is the evil-proper
;; way to do this, but the minibuffer doesn't have a mode.
;; The alternative is to create a minibuffer mode (here), but
;; then it may conflict with other packages' if they do the same.
(evil-insert 1))
(defun evil-collection-minibuffer-init ()
