This is the official repository for the Soufflé language project. The Soufflé language is similar to Datalog (but has terms known as records), and is frequently used as a domain-specific language for analysis problems.
-
Efficient translation to parallel C++ of Datalog programs
-
Efficient interpretation
-
Extended semantics of Datalog, e.g., permitting unbounded recursions with numbers and terms
-
Simple component model for Datalog specifications
-
Recursively defined record types (aka. constructors) for tuples
