22 | ;;; Commentary: | |
23 | ||
24 | ;; There are two ways to go about identifying yourself automatically to | |
25 | ;; NickServ with this module. The more secure way is to listen for identify | |
26 | ;; requests from the user NickServ. Another way is to identify yourself to | |
27 | ;; NickServ directly after a successful connection and every time you change | |
28 | ;; your nickname. This method is rather insecure, though, because no checks | |
29 | ;; are made to test if NickServ is the real NickServ for a given network or | |
30 | ;; server. | |
31 | ||
32 | ;; As a default, ERC has the data for the official nickname services on the | |
33 | ;; networks Austnet, BrasNET, Dalnet, freenode, GalaxyNet, and Slashnet. | |
34 | ;; You can add more by using M-x customize-variable RET erc-nickserv-alist. | |
35 | ||
36 | ;; Usage: | |
37 | ;; | |
38 | ;; Put into your .emacs: | |
39 | ;; | |
c6b99621 | 40 | ;; (require 'erc-services) |
597993cf MB |
41 | ;; (erc-services-mode 1) |
42 | ;; | |
43 | ;; Add your nickname and NickServ password to `erc-nickserv-passwords'. | |
44 | ;; Using the freenode network as an example: | |
45 | ;; | |
46 | ;; (setq erc-nickserv-passwords '((freenode (("nickname" "password"))))) | |
47 | ;; | |
48 | ;; The default automatic identification mode is autodetection of NickServ | |
49 | ;; identify requests. Set the variable `erc-nickserv-identify-mode' if | |
50 | ;; you'd like to change this behavior. You can also change the way | |
51 | ;; automatic identification is handled by using: | |
52 | ;; | |
53 | ;; M-x erc-nickserv-identify-mode | |
54 | ;; | |
55 | ;; If you'd rather not identify yourself automatically but would like access | |
56 | ;; to the functions contained in this file, just load this file without | |
57 | ;; enabling `erc-services-mode'. | |
