LispInABox-为什么要启动服务器？-LispInABox-Whyisitstartingaserver?

Sockets are more flexible than pipes. For one, SLIME lets you connect to Swank servers on the network, which is very useful for doing live fixes on remote machines with long-running processes (such as web servers). Given this, why would you add another layer of complexity by abstracting communication in such a way as to support both pipes and sockets? It's not like pipes are any simpler to program than sockets, anyway.

插座比管道更灵活。首先,SLIME允许您连接到网络上的Swank服务器,这对于在具有长时间运行的进程(例如Web服务器)的远程计算机上进行实时修复非常有用。鉴于此,为什么要通过以支持管道和套接字的方式抽象通信来添加另一层复杂性?无论如何,它不像管道比插座更简单。

The purpose is so that Lisp will be running in parallel.

目的是让Lisp并行运行。

Slime connects to the session and then you can have the same environment, definitions, etc from many different windows (or machines even). This means that you can start up your application and debug it on the fly, for instance.

Slime连接到会话,然后您可以从许多不同的窗口(或甚至机器)拥有相同的环境,定义等。这意味着您可以启动应用程序并在运行中进行调试。

Well, Slime starts Lisp process to give you integrated development environment. So that you can test and debug your code on the fly and also be able to inspect objects. I think architecture with sockets was chosen for better portability between different lisps (Btw, Slime also supports Clojure and MIT Scheme ) and OS-es (Slime works on Windows too). Also it allows cross-platform development - you can test your software on target architecture from your Emacs.

好吧,Slime启动Lisp进程为您提供集成开发环境。这样您就可以动态测试和调试代码,并且还可以检查对象。我认为选择具有套接字的架构是为了在不同的lisps(Btw,Slime还支持Clojure和MIT Scheme)和OS-es(Slime也适用于Windows)之间实现更好的可移植性。它还允许跨平台开发 - 您可以从Emacs在目标架构上测试您的软件。

So I think, that this decision is great, you just should not put swank (Slime back-end) on production servers.

所以我认为,这个决定很棒,你不应该把swank(Slime后端)放在生产服务器上。

You get a REPL (read-evaluate-print-loop) running in parallel, so that you can compile and test code snippets on the fly from your editor. "Practical Common Lisp" (freely available on the web) has a good explanation for this, and it is a very good book for learning Lisp.

您将获得并行运行的REPL(读取 - 评估 - 打印 - 循环),以便您可以从编辑器中动态编译和测试代码片段。 “Practical Common Lisp”(在网上免费提供)对此有一个很好的解释,这是一本非常好的学习Lisp的书。
