emacs shell 命令输出不显示 ANSI 颜色，但显示代码 [英] emacs shell command output not showing ANSI colors but the code

问题描述

当我做 M-！在我的 emacs 21.4 中，ANSI 代码是文字的.例如:ls --color

When I do M-! in my emacs 21.4 the ANSI codes gets literal. Eg: ls --color

有没有办法用颜色和 UTF8 来实现它?

Is there a way of having it with color and UTF8?

同样的问题已经在SO之前但结果并不完全令人满意(给出的解决方案是打开shell模式).我知道如何在外壳中添加颜色.我只想知道怎么和M一起上色！(shell-command) 或者根本不可能.

The same question has been answered in SO before but with not totally satisfactory results (the solution given was to open a shell-mode). I know how to have colors in a shell. I only want to know how I can have color with M! (shell-command) or if it is not possible at all.

当您只想快速显示某些内容而不想移动到此缓冲区并且希望它在没有 C-x-k 的情况下自动消失时，shell 模式太具有侵入性.显然，在某些情况下，shell 缓冲区更方便，但多亏了另一个问题，我发现了如何为 shell 模式添加颜色.

A shell mode is too intrusive when you want only to show something quick and don't want to move to this buffer and you would like to have it disappear automatically without C-x-k. Obviously there are situations where a shell buffer is more convenient but thanks to the other question I found how to put color to the shell-mode.

推荐答案

ansi-color.el 包含处理 ANSI 颜色代码的函数.不幸的是，并没有真正的好方法将它挂接到 shell-command.这是一个黑客，但它的工作原理:

ansi-color.el contains the functions to process ANSI color codes. Unfortunately, there's not really a good way to hook it into shell-command. This is something of a hack, but it works:

(require 'ansi-color)

(defadvice display-message-or-buffer (before ansi-color activate)
  "Process ANSI color codes in shell output."
  (let ((buf (ad-get-arg 0)))
    (and (bufferp buf)
         (string= (buffer-name buf) "*Shell Command Output*")
         (with-current-buffer buf
           (ansi-color-apply-on-region (point-min) (point-max))))))
