ColorScheme objects encapsulate a named set of colors to be used in the HighLine.colors() method call. For example, by applying a ColorScheme that has a :warning color then the following could be used:
colors("This is a warning", :warning)
A ColorScheme contains named sets of HighLine color constants.
Example: Instantiating a color scheme, applying it to HighLine,
and using it:
ft = HighLine::ColorScheme.new do |cs|
cs[:headline] = [ :bold, :yellow, :on_black ]
cs[:horizontal_line] = [ :bold, :white ]
cs[:even_row] = [ :green ]
cs[:odd_row] = [ :magenta ]
end
HighLine.color_scheme = ft
say("<%= color('Headline', :headline) %>")
say("<%= color('-'*20, :horizontal_line) %>")
i = true
("A".."D").each do |row|
if i then
say("<%= color('#{row}', :even_row ) %>")
else
say("<%= color('#{row}', :odd_row) %>")
end
i = !i
end
Create an instance of HighLine::ColorScheme. The customization can happen as a passed in Hash or via the yielded block. Key‘s are converted to :symbols and values are converted to HighLine constants.
