CafeOBJ 1.5.7 released
Yesterday we released CafeOBJ 1.5.7 with lots of changes concerning the inductive theorem prover CITP, as well as fixes to make CafeOBJ work with current SBCL. The documentation has gained a few more documents (albeit in Japanese), please see Documentation pages for the full list. The reference manual has been updated and is available as PDF, Html, or Wiki. To quote from our README:
CafeOBJ is a new generation algebraic specification and programming language. As a direct successor of OBJ, it inherits all its features (flexible mix-fix syntax, powerful typing system with sub-types, and sophisticated module composition system featuring various kinds of imports, parameterised modules, views for instantiating the parameters, module expressions, etc.) but it also implements new paradigms such as rewriting logic and hidden algebra, as well as their combination.
