text_box with color

[obfuscoder]

I am using text_box as it allows me to define a box which the text resides in and will never escape from. I also want to change the color of the font. However, the color option is not supported and I have no idea how I would be able to change the color while using text_box. The documentation does not provide a solution to this problem.

I would recommend either to enhance the documentation to explain, how coloring of the text can be achieved or add support for that option to that method.

It's necessary to use formatted_text_box and put the color on each fragment.

formatted_text_box([{ text: 'foobar', color: 'FF0000' }])

You could introduce a convenience function that wraps text_box:

def text_box_with_color string, opts = {}
  fragments = [{ text: string, color: opts.delete(:color) }]
  formatted_text_box fragments, opts
end

text_box_with_color 'foobar', color: 'FF0000'

But how you get a background color?

It's necessary to use a callback that draws a box using the boundaries of the fragment. You can study Asciidoctor PDF to learn how you might approach it. See https://github.com/asciidoctor/asciidoctor-pdf/blob/master/lib/asciidoctor/pdf/formatted_text/text_background_and_border_renderer.rb
