 ====== Rich Model Language ====== ====== Rich Model Language ======
  
-  ​http://​www.cl.cam.ac.uk/​research/​hvg/​Isabelle/dist/Isabelle/doc/main.pdf+===== Syntax ===== 
 + 
 +  ​lisp syntax based on Isabelle ​identifier names (perhaps clean-up names in Isabelle ​itself) 
 +  * tools to provide nicer surface syntax and generate lisp syntax 
 +    * we have a candidate using LR(1) parser (CUP) 
 +    * an earlier version: [[Vepar Grammar]] 
 + 
 +===== Semantics ===== 
 + 
 +Classical HOL 
 +  * built in operators 
 +  * define them whenever natural, or state strong enough properties 
 + 
 +===== Type System ===== 
 + 
 +Simple types 
 + 
 +Parametric polymorphism 
 + 
 +Soft typing systems on top? 
 + 
 +===== Starting Points =====

 +Document summarizing operators of interest: 
 +  * {{:​isabellemain.pdf|What'​s in Isabelle Main, October 14, 2009}} 
 + 
 +Some differences:​ 
 +  * separate operators for + on integers, reals 
 +  * no '​nat'​ for now, indexing lists gives unknown value for negative 
 +  * a '​finite'​ predicate, no separate type 
 +    * introduce a type for SMT-LIB 2.0 (same problem for maps) 
 +    * finiteness inference 
 +  * no set intervals 
 +  * option types 
 +  * a subset of list operations
