emacs - 如何在（emacs）shell命令的输出中有颜色？

Question

执行命令shell-command时，相关缓冲区中显示的输出未着色。

从 emacs 中调用测试框架（输出黄色/绿色/红色...）时，这尤其令人讨厌。

如何配置或扩展 emacs 以使shell 命令允许在 shell 中进行彩色输出并在表示该输出时保留颜色？

谢谢！

附言。我在 UN*X 系统上使用 Bash shell。

Answer 1

这可能是你想要的：

(add-hook 'shell-mode-hook 'ansi-color-for-comint-mode-on)

Answer 2

您可以实现自己的 shell 执行，例如

(defun my-shell-execute(cmd)
   (interactive "sShell command: ")
   (shell (get-buffer-create "my-shell-buf"))
   (process-send-string (get-buffer-process "my-shell-buf") (concat cmd "\n")))

Answer 3

这增加了ansi-color-apply-on-region在 shell 命令完成后在 minibuffer 上运行的建议：

(require 'ansi-color)

(defun ansi-color-apply-on-buffer ()
    (ansi-color-apply-on-region (point-min) (point-max)))

(defun ansi-color-apply-on-minibuffer ()
  (let ((bufs (remove-if-not
               (lambda (x) (string-starts-with (buffer-name x) " *Echo Area"))
               (buffer-list))))
    (dolist (buf bufs)
      (with-current-buffer buf
        (ansi-color-apply-on-buffer)))))

(defun ansi-color-apply-on-minibuffer-advice (proc &rest rest)
  (ansi-color-apply-on-minibuffer))

(advice-add 'shell-command :after #'ansi-color-apply-on-minibuffer-advice)
;; (advice-remove 'shell-command #'ansi-color-apply-on-minibuffer-advice)

它不依赖于 shell-mode 或 comint。我将其与以下内容一起使用以获得不错的测试输出（一个绿色笑脸，其中包含成功的 doctests 计数。

(defun add-test-function (cmd)
  (interactive "sCommand to run: ")
  (setq my-testall-test-function cmd)
  (defun my-testall ()
    (interactive)
    (shell-command my-testall-test-function))
  (local-set-key [f9] 'my-testall))
