[rules-users] Regex parsing of drl file versus Visitor pattern

My project uses Drools type declarations with custom annotations that are used to assist in the dynamic mapping of underlying domain data to drools fact types. I need to provide a Swing user interface for rule creation that guides the user through the custom type declarations, rules, and functions. Guvnor doesn't seem to be a good fit. I've looked at drools-verifier (and the older DrlDumper class) and its use of the Visitor pattern to traverse a rule package, but it is a lot of work to implement just for the type declaration enhancements. Producing identical DRL to the imported file seems difficult. Also, any inline comments and formatting is lost. Alternatively, I could parse (via regex patterns) the DRL to extract the type declarations, rules, and functions and then reconstruct the complete package file. This seems simpler, though brittle. Also, the regex gets complicated when attempting to get extended information (metadata, annotations, etc.). Any thoughts on either approach? Is there an easier way to process a rules file into a simple data model that doesn't lose the original DRL syntax? -- View this message in context: http://drools.46999.n3.nabble.com/Regex-parsing-of-drl-file-versus-Visito...
