What is TCLP ?

1. A prescriptive type system for Constraint Logic Programming, currently:
   • ISO-Prolog
   • GNU-Prolog
   • Sicstus Prolog and its libraries
   • Contraints programming libraries of Sicstus Prolog

2. Based on Typing Constraint Logic Programs by François Fages and Emmanuel Coquery. Journal of Theory and Practice of Logic Programming TPLP 1(6)., pp. 751-777. November 2001. Available as ps.

   TCLP uses 3 kind of polymorphism:

   • parametric polymorphism (e.g. : list(A))
   • subtyping (e.g. : list(A) < term)
   • overloading (also called adhoc polymorphism)
     e.g.: '-'/2 can have type int * int -> int and type A * B -> pair(A,B)
3. Usable:
   • No type declaration required !
     • type inference for predicates
     • default types for function symbols
   • Extensible to other dialects by providing types for built-ins

TCLP is implemented in Prolog/CHR.
