Shell-mode gives access to a shell in a normal emacs buffer, meaning you can move around and edit it as usual. A drawback is that you can not launch programs like htop or other ncurses ones.

Usage

M-x shell

Look at the menu: you have several key to interact with the shell. Some of them are:

  • [M-p] previous input of command line
  • [C-c r] go to beginnig of output (useful when you have a large output and want to read through the beginning)
  • [C-c-p] go to beginnig of previous output group


To launch a shell in the current buffer, have a look to shell-here: https://github.com/ieure/shell-here (available through ELPA).

Customisation

More colors

If you have bad colors in the output, try using ansi-mode:

    (require 'ansi-color)
    (defun colorize-compilation-buffer ()
    (toggle-read-only)
    (ansi-color-apply-on-region (point-min) (point-max))
      (toggle-read-only))
      (add-hook 'compilation-filter-hook 'colorize-compilation-buffer)

You can highlight some text based on regexp (useful to see "OK" or warnings):

      (add-hook 'shell-mode-hook (lambda () (highlight-regexp "\\[OK\\]" "hi-green-b")))


Make URLs clikable

   (add-hook 'shell-mode-hook (lambda () (goto-address-mode )))
