Something I was playing around with a couple of years ago and never took the project to full production was a user extensible machine-tool parser which kept the rules and the grammar in persistent dynamically loadable objects. I was able to load new commands on the fly, or actually change the grammar rules themselves... The intent was to provide an RS-274 (D-X) parser that the end user can overload behaviors as implemented historically by different vender's over the last 40 years. Also, to allow the end user to implement some of the more esoteric functionality (like PH and NURB curves).

I would have to reimplement it in Spirit2 and seriously clean it up though... Would something like that be interesting?

Yeah, that's cool! I'm not sure it fits the criteria I outlined though. Seems to be too complex for the cookbook? Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
