Overview

The Scannable module tries to emulate a super-simple Abstract Syntax Tree structure including method for accessing ast nodes.

Usage

Include the Scannable module and set the ‘self.scanner` value.

class ParserFoo
  include Scannable

  self.scanner = ScannerFoo
end

Now you can access the AST using the node method.

node "created_on"
# => "2009-12-12"

node? "created_on"
# => true

node? "created_at"
# => false
