scan(input_object, options: nil, &block) click to toggle source

Scans the given regular expression text, or Regexp object and collects the emitted token into an array that gets returned at the end. If a block is given, it gets called for each emitted token.

This method may raise errors if a syntax error is encountered.

def self.scan(input_object, options: nil, &block)
  new.scan(input_object, options: options, &block)
end

lazy-load property maps when first needed

Emits an array with the details of the scanned pattern

  # end-users, so we keep track of char-based indices and emit those instead.
