Method: Keybox::Application::PasswordSafe#load_color_scheme

Defined in:
lib/keybox/application/password_safe.rb

#load_color_scheme ⇒ Object

load the given color scheme. If the scheme cannot be found it will default to the :none scheme which has no color

The color_scheme file exists either in the application data directory, or in the same directory as the configuration file.

The file name convention for the scheme file is schemename.color_scheme.yaml. So for instance the default :dark_bg color scheme file is named:

dark_bg.color_scheme.yaml
