;;; Commentary:
|
|
|
|
;; This file replaces erc-complete.el. It provides nick completion
|
|
;; for ERC based on pcomplete. If you do not have pcomplete, you may
|
|
;; try to use erc-complete.el.
|
|
;;
|
|
;; To use, (require 'erc-auto) or (require 'erc-pcomplete), then
|
|
;; (erc-pcomplete-mode 1)
|
|
;;
|
|
;; If you want nickname completions ordered such that the most recent
|
|
;; speakers are listed first, set
|
|
;; `erc-pcomplete-order-nickname-completions' to t.
