Lisaac: The power of simplicity at work for operating systems

Identity card
concept small prototype-based programming language
The ideas in Lisaac are mostly inspired by Smalltalk (all values are objects), Self (prototype-based)
and Eiffel (design by contract)
platforms all platforms (host/target specific for GCC)
features pure object language
very fast (like C code)
dynamic and multiple inheritance
dynamic definition slot
static typing (invariant)
genericity type
auto-cast type system
programming by contract
interrupt manager
include C code facilities
emacs

Making a new operating system drive us to conceive a new programmation language : Lisaac.

This language based on prototype object is strongly inspired from self language.

More than the advantages of self, Lisaac give protection of comunication mecanism and operating system tools.

Using prototype and dynamic inheritance is fully adapted to the conception of operating system.

First tests learn us, that Lisaac compiler is able to give the same performance than C compiler. Lisaac inherit of Self's semantic and of the Eiffel's static typing.
