如何得到抑制^ M字符在我ClojureBox（EmacsW32）REPL连接到lein swank

问题描述

我从我的安装连接到swank服务器。也就是说 lein swank 从我的项目目录，然后 Mx slime-connect 从EmacsW32。

然而，当我这样做，我看到在REPL（ ^ M ）的DOS行结尾。即

  user> （doc map）
 ------------------------- M 
 clojure.core / map ^ M 
 （[f coll] [f c1 c2] [f c1 c2 c3] [f c1 c2 c3& colls]）^ M 
返回由将f应用于
集合的结果组成的延迟序列的每个coll的第一项，随后将f应用于每个coll中的第二项的集合
，直到任一个coll是
 exhausted。其他coll中的任何剩余项目将被忽略。函数
 f应该接受colls参数。^ M 
 nil 
 
用户> （printlnfoo）
 foo ^ M 
  

做平台编码，但我有麻烦了解如何抑制它们。我在EmacsW32菜单中戳了一下，尝试使用java命令行系统属性（在lein.bat中） -Dfile.encoding = ISO-8859-1 p>

我还发现了关于在缓冲区中进行全局查找/替换^ M的其他问题 - 但我想过滤REPL输出。

我也注意到 * inferior-lisp * 缓冲区中的以下内容：

（do（.. java.net.InetAddress getLocalHost getHostAddress）nil）（swank.swank / start-serverc：/Users/noahz/AppData/Local/Temp/slime.4912：encodingiso-latin -1-unix）

解决方案

 （defun hide-eol（）
不要在包含UNIX和DOS行结尾的文件中显示^ M
（交互）
（setq buffer-display-table）
（aset buffer-display-table？\ ^ M []）
  

我需要时用Mx hide-eol调用它。

信用是由于个人未知 - 我从某处复制了这个函数，但是我从一个地方复制了这个函数不记得哪里。

I am connecting to a swank server from my ClojureBox install. I.e. lein swank from my project directory and then M-x slime-connect from EmacsW32.

However, when I do this I see the DOS line-endings everywhere in the REPL (^M). I.e.

user> (doc map)
-------------------------^M
clojure.core/map^M
([f coll] [f c1 c2] [f c1 c2 c3] [f c1 c2 c3 & colls])^M
  Returns a lazy sequence consisting of the result of applying f to the
  set of first items of each coll, followed by applying f to the set
  of second items in each coll, until any one of the colls is
  exhausted.  Any remaining items in other colls are ignored. Function
  f should accept number-of-colls arguments.^M
nil 

user> (println "foo")
foo^M

I'm aware that this has to do with platform encoding, but I'm having trouble figuring out how to suppress them. I poked around in the EmacsW32 menus and tried the java command line system property (in lein.bat) -Dfile.encoding=ISO-8859-1 to no avail.

I've also found other questions about doing global find/replace of ^M within buffers - but I want to filter REPL output.

I also noticed the following in the *inferior-lisp* buffer:

(do (.. java.net.InetAddress getLocalHost getHostAddress) nil)(swank.swank/start-server "c:/Users/noahz/AppData/Local/Temp/slime.4912" :encoding "iso-latin-1-unix")

解决方案

I have this in my .emacs:

(defun hide-eol ()
  "Do not show ^M in files containing mixed UNIX and DOS line endings."
  (interactive)
  (setq buffer-display-table (make-display-table))
  (aset buffer-display-table ?\^M []))

I just call it with M-x hide-eol when required. You could bind a key, or put it in a hook of some sort if you prefer.

Credit is due to persons unknown - I copied this function from somewhere, but I don't remember where.
