Extensions

ChalkX11

This extension class adds proper methods to Chalk for all of the standard X11/CSS/SVG color names for use by Chalk. This extension has the added advantage of providing code completion and type checking at coding/compile time. Using the dynamic color method cannot provide any coding/compile time checks because it works via a dynamic lookup at run time. Example of using this extension for Chalk: chalk.lightGoldenrodYellow.onCornflowerBlue(...) versus having to use the color (or css or x11) method to get a dynamic so you can use the dynamic lookups: chalk.color.lightGoldenrodYellow.onCornflowerBlue(...) Because of the dynamic lookup is not resolved until run time that method can be prone to errors which would not be detected until run time.
