@hsbt Do you need other people's implementations?

[aycabta]

Squashed:

• Replaced IRB based lexer with Ripper.
  • Use Ripper for lexical analyser #512
  • It much improves the speed of generating documents.
  • To facilitate supporting new syntax in the future.
• Supported many new syntaxes of Ruby in the past few years.
• Used "frozen_string_literal: true". It reduces documents generation time by 5%.
• Supported did_you_mean.
