使用 leiningen 和 swank/slime 在 emacs 中运行 clojure 测试时停止无限循环
在某些类型的代码中，在不破坏堆栈的情况下相对容易导致无限循环。当使用 clojure-test 测试这种性质的代码时，有没有办法在不重新启动 swank 服务器的情况下中止当前正在运行的测试？
目前我的工作流程涉及
$ lein swank
使用 slime-connect 通过 emacs 连接到 swank，然后切换到测试，使用 Cc C-, 执行，测试运行直到无限循环，然后刚返回，但测试中一个 cpu 仍在不停地运转。我发现阻止这个问题的唯一方法是重新启动 lein swank，但这似乎是一个相对常见的问题？有人有更好的解决方案吗？
In certain kinds of code it's relatively easy to cause an infinite loop without blowing the stack. When testing code of this nature using clojure-test, is there a way to abort the current running tests without restarting the swank server?
Currently my workflow has involved
$ lein swank
Connect to swank with emacs using slime-connect, and switch to the the tests, execute with C-c C-,, tests run until infinite loop, then just return but one cpu is still churning away on the test. The only way to stop this I have found is to restart lein swank, but it seems like this would be a relatively common problem? Anyone have a better solution?

是的，在开发中编写无限循环是程序员的常见问题:)。答案很简单。它被称为“中断命令”，它是
Cc CbLeiningen 与此无关。这是 SLIME/Swank/Clojure。当您在 Emacs 中评估代码时，您将在 Clojure 中生成一个新线程。 SLIME 保留对这些线程的引用，并显示有多少线程在 Emacs 模型行中运行。如果您处于图形环境中，您可以单击模型行，其中指示您的名称空间并看到许多选项。一种选择是“中断命令”
Eval
(while true)和Cc Cb来获取一个显示java.lang.ThreadDeath错误的对话框，其中可能包含只有一个选择。您可以键入0或q退出该线程，终止该错误消息缓冲区并将焦点返回到之前的缓冲区。Yes, it is a common problem for programmers to write infinite loops in development :). And the answer is very simple. It's called "Interrupt Command" and it is
C-c C-bLeiningen has nothing to do with this. This is SLIME/Swank/Clojure. When you evaluate code in Emacs you are spawning a new thread within Clojure. SLIME keeps reference to those threads and shows you how many are running in the Emacs modeline. If you're in a graphical environment you can click the modeline where it indicates your namespace and see lots of options. One option is "Interrupt Command"
Eval
(while true)andC-c C-bto get a dialog showing ajava.lang.ThreadDeatherror with probably just one option. You can type0orqto quit that thread, kill that error message buffer and return focus to your previous buffer.根据此旧讨论，添加
(use 'clojure.contrib.repl-utils))和(add-break-thread!)到 user.clj 应该使您能够按Cc Cc用于将 SIGINT 传递给长时间运行的评估/进程。As per this old discussion, adding
(use 'clojure.contrib.repl-utils))and(add-break-thread!)to user.clj should enable you to pressC-c C-cfor passing SIGINT to the long running evaluation/processe.如果一切都失败了..
alt-x slime-quit-lisp并重新启动 REPL。当然首先尝试 Psyllo 的答案。if all else fails..
alt-x slime-quit-lispand restart the REPL. try Psyllo's answer first of course.
