Lolli
<language> (Named after the "lollipop" operator "-o") An
interpreter for
logic programming based on
linear logic, written by Josh Hodas <
[email protected]>.
Lolli can be viewed as a refinement of the Hereditary Harrop formulas of Lambda-Prolog.
All the operators (though not the higher order unification) of Lambda-Prolog are supported, but with the addition of linear variations.
Thus a Lolli program distinguishes between clauses which can be used as many, or as few, times as desired, and those that must be used exactly once.
Lolli is implemented in
SML/NJ.
