Proof of Concept: attempt to use the puppet parser and lever for better accuracy and consistency.

[rnelson0]

See hlindberg/misc-puppet-docs#8 for a description of how to use the parser/lexer.

As this is a proof of Concept, work will not be done in the master branch and may even be done in a different repo. This project will be worked on during the December 13th hackathon, too.

I started creating an example API tool at https://github.com/rnelson0/puppet-parser_api_example. It currently parses and validates code; next is enumerating the tokens in the lexer.

See #586 for code validation and #584 for better lexing.
