OK, I did some playing. Regexp names can't be looked up sensibly in other dssls. The reason is the lookup needs to be done when the "rule" for a grammar production is layed down (i.e. translated from Felix to Dypgen). This is done when building the dssl, before opening it. So foreign regdef names don't exist yet.
Unfortunately the binding is directly to a Dyp.regexp term, and there's no further point at which the lookup can be done. There's no way in Dypgen to add to the list of pre-defined regexps (defined by let in the %lexer section of the hard coded grammar). So, the binding requires all the regexps locally. You just need to define nonterminals in the same dssl. If you need a new literal .. you have to redefine the regexps required. I may find a solution to this later. Note, the regexps are tree-expanded anyhow (so there's no saving using names). -- john skaller skal...@users.sourceforge.net http://felix-lang.org ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Felix-language mailing list Felix-language@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/felix-language
