Enable syntax highlighting as you type in the Rails console via coolline and coderay (MRI 1.9.3+ only). Disabled by default as it's a bit buggy.
Call from a Rails initializer:
FunkHands.enable_syntax_highlighting_as_you_type!
# File lib/funk_hands.rb, line 40 def enable_syntax_highlighting_as_you_type! raise 'Syntax highlighting only supported on 1.9.3+' unless RUBY_VERSION >= '1.9.3' # Use coolline with CodeRay for syntax highlighting as you type. # Only works on >= 1.9.3 because coolline depends on io/console. require 'coolline' require 'coderay' Pry.config.input = Coolline.new do |c| c.transform_proc = proc do CodeRay.scan(c.line, :ruby).term end c.completion_proc = proc do word = c.completed_word Object.constants.map(&:to_s).select { |w| w.start_with? word } end end end
Also aliased as: enable_syntax_highlighting_as_you_type
