Module: Lexdrill::Colorizer

Defined in:
lib/lexdrill/colorizer.rb

Overview

Wraps text in an ANSI color code. paint_by_count maps a word's show count onto a blue -> red truecolor gradient, one step per Lexdrill::Stats::BUCKET_SIZE shows, so a word's color reflects how many times it's been drilled — unless drill color random is set (see Lexdrill::Color), in which case a vivid random color is used every time instead.
