Recently I want to log my IRC traffic even when I’m away so I registered a free shell account on shellmix.com and configured ZNC to run on it. ERC is my choice of IRC client. It’s powerful and heavily customizable because of Emacs’ nature (E-Lisp for extensions). Here’s my .emacs config:

;; erc logging
(setq erc-generate-log-file-name-function 'erc-generate-log-file-name-with-date
erc-log-matches-flag t
erc-save-buffer-on-part nil
erc-save-queries-on-quit nil
erc-log-write-after-send t
erc-log-write-after-insert t
erc-log-file-coding-system 'utf-8)

Above config makes ERC log every message and write to log files right after receive or send. I don’t want it to write when I close Emacs and then ask for saving ~.~, which is the default behavior.

That’s all, folks 😀 .
