Mercury programming language
|
|
Mercury is a functional/logical programming language based on Prolog, but more useful for real-world programming.
Mercury is compiled rather than interpreted, as is traditional for logic languagues. It features a sophisticated, strict type and mode system. Its authors claim these features and logic programming's abstract nature speeds writing of reliable programs. Mercury's module system enables division into self-contained units, a problem for past logic programming languages.
Hello World in Mercury:
:- module hello_world.
:- interface.
:- import_module io.
:- pred main(io__state, io__state).
:- mode main(di, uo) is det.
:- implementation.
main -->
io__write_string("Hello, World!\n").
(by Ralph Becket (http://www.cs.mu.oz.au/research/mercury/tutorial/hello-world.html) at the University of Melbourne):
Mercury is developed at the University Of Melbourne Computer Science department under the supervision of Dr. Zoltan Somogyi.
Unfortunately, the current Mercury implementation lacks user level documentation (only reference documentation exists). Thus it is almost unused outside the team of its creators.
