Description

This layer colors your life with:

• rainbow identifiers
• rainbow mode
• [nyan mode][]

rainbow identifiers mode will colorize each variables and functions with an almost unique color. The keywords and the declaration of function colors are disabled in order to make the colorized variables and functions stand out.

rainbow mode displays strings representing colors with the color they represent as background.

[nyan mode][] display a Nyan cat progress bar in the mode-line.

Install

To use this contribution add it to your ~/.spacemacs

(setq-default dotspacemacs-configuration-layers '(colors)
  "List of contribution to load."
)

Enable rainbow-identifiers

To enable the package rainbow-identifiers set the variable colors-enable-rainbow-identifiers to t:

(setq-default dotspacemacs-configuration-layers '(
  (colors :variables colors-enable-rainbow-identifiers t))
  "List of contribution to load."
)

Enable Nyan cat

To enable the package nyan-mode set the variable colors-enable-nyan-cat-progress-bar to t:

(setq-default dotspacemacs-configuration-layers '(
  (colors :variables colors-enable-nyan-cat-progress-bar t))
  "List of contribution to load."
)

It may be handy to enable it only in a GUI, you can do it by using a quasi-quoted list:

(setq-default dotspacemacs-configuration-layers
  `((colors :variables
            colors-enable-nyan-cat-progress-bar ,(display-graphic-p)))
  "List of contribution to load."
)
