Re: Different background color for different windows/modes

[Alexandre Oberlin <alxobr@gmail.com>]

Hello,

Someone gave me a hint to do this in Emacs 24.4+ but I don't find the message on gnu.emacs.help (Is this NG dying?). 

The trick is to uses defface and face-remap-add-relative. It works very well, including in GNU Emacs 24.5.1 (x86_64-unknown-cygwin) under Cygwin without X.

To modify the font and colors of your shell windows for instance, just add/load the code below from your .emacs and add more attributes and more modes (text, lisp, etc.) as desired. 

The commented out entries are not necessary but may come handy when tweaking your config.

Important: this code should be loaded before you visit/find any concerned file or launch a shell from .emacs. 

;;;;;;;;;;;;;;;;;;;;;;;; BEGIN .emacs CODE ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; (face-spec-reset-face 'myshellface)
(defface myshellface
  '((t :foreground "black"
       :background "aquamarine"
       :weight semi-bold
       :underline nil
       ))
  "Face for shells."
  :group 'myfaces )

;; (face-spec-set
;;  'myshellface
;;    '((t :foreground "black"
;;        :background "aquamarine"
;;        :weight semi-bold
;;        :underline nil
;;        ))
;;  'face-defface-spec
;;  )

;; (facep 'myshellface)
;; (boundp 'myshellface)
;; (remove-hook 'shell-mode-hook
;; (lambda ()
;;   (face-remap-add-relative 'default 'myshellface)))

(setq shell-mode-hook nil)
(add-hook 'shell-mode-hook
          (lambda ()
            (face-remap-add-relative 'default 'myshellface)))

;;;;;;;;;;;;;;;;;;;;;;;; END .emacs CODE ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;


Cheers,
