- Contains a large part of a Common Lisp implementation. Not a toy.
- Includes the org.jatha.dynatype package that implements a hierarchy of dynamically-typed data types that follows the Common LISP set of data types.
- Useful as an embedded library, or as a stand-alone application.
The API allows programmatic access to LISP from Java, either using an eval() method or using Java methods, e.g.
Additional LISP primitives can be written in Java and registered at runtime to be used in the LISP interpreter. The LISP engine compiles the input forms to an abstract machine code specified in Kogge's book "The Architecture of Symbolic Machines". The engine is pretty fast on today's computers. The following program can calculate 2^128 = 340282366920938463463374607431768211456 in about 4 milliseconds:
The Jatha library is covered by the Gnu Lesser General Public License, which allows libraries to be combined with non-free software.
