undefined method `parse_failure_cause' #173

Closed Mackaber closed 7 years ago

Trying to run the examples included in your getting started guide (http://kschiess.github.io/parslet/get-started.html) gets me the error: 

NoMethodError: undefined method `parse_failure_cause' for #<Parslet::ParseFailed:0x007f93b142f648>
        from miniparser.rb:22:in `rescue in parse'
        from miniparser.rb:18:in `parse'
        from (irb):6
        from /Users/mackaber/.rvm/rubies/ruby-2.1.8/bin/irb:11:in `<main>'

However looking at the documentation I realized it should be:

     failure.cause.ascii_tree

Not 

    failure.parse_failure_cause.ascii_tree

Yeah, that's because we've published the new versions API ahead of time. It used to be just cause.
