在emacs中隐藏^ M [英] Hiding ^M in emacs

问题描述

有时我需要在行尾读取具有^ M（control-M）的日志文件。我可以做一个全局的替换来摆脱它们，但是更多的东西被记录到日志文件中，当然，它们都会回来。

Sometimes I need to read log files that have ^M (control-M) in the line endings. I can do a global replace to get rid of them, but then something more is logged to the log file and, of course, they all come back.

设置unix-样式或dos类型的行尾编码似乎没有太大的区别（但是unix样式是我的默认值）。我正在使用未定义的（unix | dos）编码系统。

Setting unix-style or dos-style end-of-line encoding doesn't seem to make much difference (but unix-style is my default). I'm using the undecided-(unix|dos) coding system.

我在Windows上，读取log4net创建的日志文件（尽管log4net显然不是只有这个烦恼的来源）。

I'm on windows, reading log files created by log4net (although log4net obviously isn't the only source of this annoyance).

任何提示？

推荐答案

(defun remove-dos-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 []))
