emacs rainbow-mode and rainbow.el 安裝

 
rainbow-mode 
用途：在特定語句或語法時，會產生顏色
安裝方法：
M-x package install -> rainbow-mode 
結果圖：


rainbow.el 
用途：在對應的delimiters會也相對應的顏色
安裝方法：
MELPA 好像也有這個package，但是好像有點錯誤，不知為何無法下載，感覺像是還沒放到伺服器上。
所以，只好使用老方法下載安裝了~~

git clone https://github.com/jlr/rainbow-delimiters.git
(add-to-list 'load-path "/path/to/rainbow-delimiters/") ;
(require 'rainbow-delimiters)
(global-rainbow-delimiters-mode)

個人感覺，原本的顏色不是很好，因此，透過rainbow-mode，稍微修改了一下rainbow-delimiter.el裡的顏色
