Styling cli-tools

Beauty is in the eye of the beholder; cli-tools makes a default set of choices for what kind of colors and fonts to use for its output, but this can be overridden.

Styles are defined by two vars in namespace net.lewisship.cli-tools.styles; each is a map from a usage name (such as :tool-name-label) to a font definition.

• default-styles are the defaults for all usages
• *style-overrides* contains overrides for default-styles (and is dynamic)

By overriding or rebinding this var, the fonts can be overridden.

The most common usages to override are:

• :tool-name (default :bold.green) used when writing the name of the tool itself
• :command-path (default :bold.green) used when writing the command path

Example:

    (binding [style/*style-overrides* {:tool-name :inverse.bold}]
      (cli-tools/dispatch { ... }))
