I'm not an expert at archetypes by any means, but I did kinda/sorta figure out some basics when I put together the JPA archetypes. I'd be happy to help if I can. Going one further, I wonder if there would be a way to just make a single engine that could dynamically generate the artifacts it needs o

Derek, et al, Thanks for all the kind feedback. i could use a little help with one thing. In addition to this project, i've also got - A project exploring how a relational query language is generated from a DSL describing typed sets of tuples - A pro

We just can't be half-assed about anything, can we? ;) Seriously, this is really, really cool. I'm looking forward to seeing how this grows. Derek On Mon, May 4, 2009 at 7:55 PM, Meredith Gregory wrote: > Lifted, Scalad and lasses, > > Recently Martin passed along a little code challenge regardi

Right ... I always found combinator parsers a very nice fit for BNF. I agree these parser are not trivial but I still like them a lot :) Br's, Marius On May 5, 5:48 pm, Meredith Gregory wrote: > Marius, > > Thanks for the query. Yes, there is a not so subtle point. Take a look at > the > gramm

Marius, Thanks for the query. Yes, there is a not so subtle point. Take a look at the grammar. To my way of thinking, these are it's advantages. - Readable (and therefore maintainable) - Targets the following la
