What is LiLFeS?

LiLFeS is a programming language using Typed Feature Structures. LiLFeS features

• Manipulation of feature structures as builtin data structure --- LiLFeS is a logic programming language similar to Prolog. You can easily write programs with typed feature structures, such as unification grammars and parsers.
• High-speed runtime system --- LiLFeS runtime system can efficiently process Unification of Feature Structures at high speeds, which tend to require heavy processing.
• Feature Structure database --- Users can use databases with feature structure keys.
• C++ libraries --- You can implement C++ programs to deal with feature structures.

System Requirements

OS: Linux, Solaris
Compiler: g++ 3.2 or newer
You can also compile LiLFeS on Cygwin.
