NAME
    Color::Theme::Role - Role for class wanting to support color themes

VERSION
    This document describes version 0.020 of Color::Theme::Role (from Perl
    distribution Color-Theme-Role), released on 2018-02-25.

DESCRIPTION
    This role is for class that wants to support color themes. Color theme
    is represented as a structure according to the specification described
    in Color::Theme.

    Color theme module. Color themes are put in modules under
    "Color::Theme::Themes::" (configurable using "color_theme_module_prefix"
    attribute). Each color theme modules can contain one or more color
    themes. The module must define a package global variable named
    %color_themes that contain color themes keyed by their names. Example:

     package MyProject::ColorThemes::Default;

     our %color_themes = (
         no_color => {
             v => 1.1,
             summary => 'Special theme that means no color',
             colors => {
             },
             no_color => 1,
         },

         default => {
             v => 1.1,
             summary => 'Default color theme',
             colors => {
             },
         },
     );

ATTRIBUTES
  color_theme => HASH
    Get/set color theme.

  color_theme_args => HASH
    Get/set arguments for color theme. This can be

  color_theme_module_prefix => STR (default: CLASS + "::ColorTheme::")
    Each project should have its own class prefix. For example,
    Text::ANSITable has its color themes in "Text::ANSITable::ColorTheme::"
    namespace, Data::Dump::Color has them in
    "Data::Dump::Color::ColorTheme::" and so on.

METHODS
  $cl->list_color_themes($detail) => array
    Will search packages under "color_theme_module_prefix" for color theme
    modules, then list all color themes for each module. If, for example,
    the color theme modules found are "MyProject::ColorTheme::Default" and
    "MyProject::ColorTheme::Extras", will return something like:

     ['Default::theme1', 'Default::theme2', 'Extras::extra3', 'Extras::extra4']

  $cl->get_color_theme($name) => hash
    Get color theme hash data structure by name. Note that name must be
    prefixed by color theme module name (minus the
    "color_theme_module_prefix").

  $cl->get_theme_color($item_name) => str
    Get an item's color value from the current color theme (will get from
    the color theme's "colors" hash, then the $item_name key from that
    hash). If color value is a coderef, it will be

  $cl->get_theme_color_as_rgb($item_name, \%args) => str|hash
    Like "get_theme_color", but if the resulting color value is a coderef,
    will call that coderef, passing %args to it and returning the value.
