要在Lisp中实现基于Web的实时协作工具,可以借助现有的Web开发框架如Hunchentoot或者Clack。以下是一些步骤和示例代码:
(ql:quickload :hunchentoot)
(defpackage :my-app
(:use :cl :hunchentoot))
(in-package :my-app)
(defun handle-request (request)
(format nil "Hello, World!"))
(setf (hunchentoot:define-easy-handler (my-handler :uri "/") (request)
(handle-request request))
(ql:quickload :clack-websocket)
(defun websocket-handler (env)
(clack.websocket:websocket-handshake env
:on-open (lambda (websocket)
(format t "WebSocket connected!"))
:on-message (lambda (websocket message)
(format t "Received message: ~a" message))
:on-close (lambda ()
(format t "WebSocket disconnected!"))))
(defvar *shared-doc* (make-hash-table))
(defun update-shared-doc (key value)
(setf (gethash key *shared-doc*) value))
(defun get-shared-doc (key)
(gethash key *shared-doc*))
(defun chat-message (user message)
(update-shared-doc user message))
(defun handle-chat (request)
(if (hunchentoot:request-header request "Upgrade")
(clack.websocket:websocket-handler request)
(format nil "Please upgrade to WebSocket for real-time chat.")))
需要注意的是,以上示例代码只是简单的演示,实际应用中可能需要更复杂的逻辑和功能。同时,Lisp在Web开发方面的生态相对较小,可能需要更多的自行实现或者使用第三方库来实现特定功能。
