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
Use git to obtain the source code of Soufflé.
$ git clone git://github.com/souffle-lang/souffle.git
Build instructions can be found here.
If you have written code for an older version of Souffle, please use the command line flag --legacy.
Alternatively, please add the following line to the start of your source-code:
.pragma "legacy"
