Common lisp 连接到松弛IRC网关时出错
我正在使用库通过Slack提供的IRC网关连接Slack 但是,当我尝试使用Common lisp 连接到松弛IRC网关时出错,common-lisp,irc,slack,sbcl,Common Lisp,Irc,Slack,Sbcl,我正在使用库通过Slack提供的IRC网关连接Slack 但是,当我尝试使用读取消息循环启动消息循环时,出现以下错误: error while parsing arguments to DESTRUCTURING-BIND: invalid number of elements in ("duncan_bayne" "Welcome" "to" "Slack" "IRC" "Gateway" "server" "duncan_bayne!~duncan_bayne@1.2.
读取消息循环启动消息循环时,出现以下错误:

to satisfy lambda list

我不确定我在这里做错了什么;我相当肯定这不是我的钩子,因为即使我禁用了所有钩子,问题仍然存在
此外,如果我不尝试启动消息循环,我也可以按预期使用连接,比如加入一个通道并发送消息
我猜Slack是在用一条意外消息响应连接?正如@jkilski所建议的,修复方法是修改cl irc,以接受Slack的稍微不寻常(但可能是标准编译器?)响应:
(in-package #:cl-irc)
(defmethod default-hook ((message irc-rpl_welcome-message))
(with-slots
(connection host user arguments)
message
(destructuring-bind
(nickname &rest welcome-message)
arguments
(setf (user connection)
(make-user connection
:nickname nickname
:hostname host
:username user)))))
(in-package #:irc)
(defmethod default-hook ((message irc-rpl_namreply-message))
(let* ((connection (connection message)))
(destructuring-bind
(nick chan-visibility channel &optional names)
(arguments message)
(declare (ignore nick))
(let ((channel (find-channel connection channel)))
(setf (visibility channel)
(or (second (assoc chan-visibility
'(("=" :public) ("*" :private) ("@" :secret))
:test #'string=))
:unknown))
(unless (has-mode-p channel 'namreply-in-progress)
(add-mode channel 'namreply-in-progress
(make-instance 'list-value-mode :value-type :user)))
(dolist (nickname (tokenize-string names))
(let ((user (find-or-make-user connection
(canonicalize-nickname connection
nickname))))
(unless (equal user (user connection))
(add-user connection user)
(add-user channel user))
(set-mode channel 'namreply-in-progress user)
(let* ((mode-char (getf (nick-prefixes connection)
(elt nickname 0)))
(mode-name (when mode-char
(mode-name-from-char connection
channel mode-char))))
(when mode-name
(if (has-mode-p channel mode-name)
(set-mode channel mode-name user)
(set-mode-value (add-mode channel mode-name
(make-mode connection
channel mode-name))
user))))))))))
我已申请加入开发人员邮件列表,不久将提交修补程序。如果将分解绑定(在event.lisp第149行中)更改为(昵称和rest欢迎消息)
,请查看是否有其他错误。WELCOME-MESSAGE
似乎没有任何用途,因此可能开发人员只是忘记了&rest,而它恰好在他的测试用例中工作。如果您可以修复它并提交补丁,那就太好了。否则,上次我试着用IRC做一些事情时,我使用了它,它成功了。
