Manual install

(add-to-list 'load-path "~/Projects/elisp/flycheck-css-colorguard/")
(load-library "flycheck-css-colorguard")
(eval-after-load 'flycheck
  '(add-hook 'flycheck-mode-hook #'flycheck-css-colorguard-setup))

Usage

Just open any css file. If flycheck is properly configured, flycheck-css-colorguard will start automatically.

CSS Colorguard installation

Make sure that you have CSS colorguard installed npm install -g colorguard.

Use CSS Colorguard version 1.0.0 or higher! If you for some reason need to support CSS Colorguard older then 1.0.0, take oldest revision of flycheck-css-colorguard.el and uncomment :error-parser and comment :error-patterns code.

If you can't install CSS Colorguard globally or can't put executable in $PATH:

(custom-set-variables
 '(flycheck-css-colorguard-executable "~/my_executables/colorguard"))')

CSS Colorguard options

CSS Colorguard supports only two options: --treshold <value from 0 to 100> and --options <your configuration in json file>. You can set those in your init.el:

(custom-set-variables
 '(flycheck-css-colorguard-threshold "5"))

If you set --options config file, CSS Colorguard will ignore --threshold, so there is no point for setting both of those.

(custom-set-variables
 '(flycheck-css-colorguard-config "config.json"))
