Instance Method Details

#enable_syntax_highlighting_as_you_type ⇒ Object

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:

JazzHands.enable_syntax_highlighting_as_you_type
