;;; Commentary:
;; To enable this, install company mode (https://company-mode.github.io/)
;; and add
;;
;; (require 'notmuch-company)
;;
;; to your .emacs.
;;
;; NB company-minimum-prefix-length defaults to 3 so you don't get
;; completion unless you type 3 characters
;;; Code:
(require 'company)
(require 'message)
(require 'notmuch-lib)
(defvar-local notmuch-company-last-prefix nil)
;;;###autoload
(defun notmuch-company (command &optional arg &rest ignore)
"`company-mode' completion back-end for `nevermore (nm)'."
