Rainbow-blocks is an Emacs mode that highlights blocks made of parentheses, brackets, and braces according to their depth. Each successive level is highlighted in a different color. This makes it easy to orient yourself in the code, and tell which statements are at a given level.
Highlighting scope rather that syntax is sometimes more useful for Clojure/Lisp languages, and sometimes even Python.
It is a fork from the brilliant rainbow-delimiters.el package, and only applies minor patches.
-
Install via melpa:
M-x package-install RET rainbow-blocks RET -
Compile the file (necessary for speed):
M-x byte-compile-file [location of rainbow-blocks.el] -
Add the following to your dot-emacs/init file:
(require 'rainbow-blocks) -
Activate the mode in your init file (e.g. for clojure):
(add-hook 'clojure-mode-hook 'rainbow-blocks-mode) -
It is also often useful to temporarily enable the mode by just calling:
M-x rainbow-blocks-mode
