cafeobj - algebraic specification and programming language
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
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
selects the underlying common lisp engine. If not given, the first one selected
during build time is used.
lists all available common lisp engines
sets the path where memory dumps of the lisp interpreters are found
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
gives the standard prelude file defining modules
load additional prelude file
set list of pathnames for module search path, separated by colons
adds a list of pathname for module search path
FILES files that are loaded at startup time in order.
