Colorize the mode line according to the Flycheck status. This package provides the `flycheck-color-mode-line-mode' minor mode which changes the color of the mode line according to the status of Flycheck syntax checking. To enable this mode in Flycheck, add it to `flycheck-mode-hook': (add-hook 'flycheck-mode-hook 'flycheck-color-mode-line-mode) Thanks go to: - Thomas Järvstrand (tjarvstrand) for the initial code from the excellent EDTS package - Sebastian Wiesner (lunaryorn) for flycheck and his awesome support.
