ErcAlias

Defining an alias works as follows:

    ERC> /alias foo privmsg kensanata yow!

Now you can use the new command FOO to trigger the stored command:

    ERC> /foo

And here is the code:

    (defun erc-cmd-ALIAS (command &rest words)
      (fset (intern (concat "erc-cmd-" (upcase command)))
            (list 'lambda '(&rest ignore)
                  (list 'erc-send-command (mapconcat 'identity words " ")))))

Another use would be “templates”. By defining the following template, you can use /foo to save you some typing:

    ERC> /template foo don't do this!
    ERC> /foo
    ERC> don't do this!

And here is the code:

    (defun erc-cmd-TEMPLATE (command &rest words)
      (fset (intern (concat "erc-cmd-" (upcase command)))
            `(lambda ()
	       (run-with-idle-timer 0 nil
				    (lambda (&rest ignore)
				      (insert ,(mapconcat 'identity words " ")))))))

It is also easy to implement new ERC aliases entirely in Emacs Lisp. For example, here’s a /WII alias, which can save you a lot of typing if you find yourself often typing /WHOIS with two arguments (i.e. to see idle information about a connected IRC user):

    (defun erc-cmd-WII (nick &rest ignore)
      (erc-send-command (mapconcat #'identity (list "WHOIS" nick nick) " ")))

Now you can type the short form:

    /WII nickname

instead of the longer form:

    /WHOIS nickname nickname
