cafeobj [OPTION]... [FILES]...

Starts the CafeOBJ interpreter.

CafeOBJ is a most advanced formal specification language which inherits many advanced features (e.g. flexible mix-fix syntax, powerful and clear typing system with ordered sorts, parameteric modules and views for instantiating the parameters, and module expressions, etc.) from OBJ (or more exactly OBJ3) algebraic specification language.

CafeOBJ is a language for writing formal (i.e. mathematical) specifications of models for wide varieties of software and systems, and verifying properties of them. CafeOBJ implements equational logic by rewriting and can be used as a powerful interactive theorem proving system. Specifiers can write proof scores also in CafeOBJ and doing proofs by executing the proof scores.

CafeOBJ has state-of-art rigorous logical semantics based on institutions. The CafeOBJ cube shows the structure of the various logics underlying the combination of the various paradigms implemented by the language. Proof scores in CafeOBJ are also based on institution based rigorous semantics, and can be constructed using a complete set of proof rules.

There are two classes of options. The first are options for the cafeobj wrapper script that allows to select the underlying Common Lisp interpreter, and to adjust search path parameters.

-engine NAME

selects the underlying common lisp engine. If not given, the first one selected during build time is used.

-list-engines

lists all available common lisp engines

-wrapper-libpath PATH

sets the path where memory dumps of the lisp interpreters are found

-wrapper-sharepath PATH

sets the path where CafeOBJ initialization files are searched

The following set of options are directed at the CafeOBJ interpreter directly:

-help

print a help message

-q

do not load user's initialization file

-batch

run in batch mode

-p PATH

gives the standard prelude file defining modules

+p PATH

load additional prelude file

-l DIR-LIST

set list of pathnames for module search path, separated by colons

+l DIR-LIST

adds a list of pathname for module search path

FILES

files that are loaded at startup time in order.
