The three Rubies
and Salama
Syntax
and meaning
Pure OO, blocks, closures,clean syntax, simple but consistant, open classes
Just to name a few of the great features of the ruby syntax and it's programming model.
Syntax is an abstract thing, as far as i know there is no ebnf or similar definition of it.
Also as far as i know there is only the mri which is considered the only source of how ruby works.
With more vm's appearing this is changing and the mpsec is apparently catching up.
As we are just starting we focus on oo consistency and implement only essential features.
Vm
Salama
The heart of the salama project is salama, the virtual machine
Salama is written in 100% ruby
Salama uses an existing ruby to bootstrap itself
Salama generates native code, and ( with 1+2) creates a native ruby virtual machine.
Salama does not interpret, it parses and compiles (just making sure that's clear)
Salama uses a statically typed value based core with rtti and oo syntax to achieve this (think c++ with ruby syntax)
Core Library
Parfait
Ruby has core and std lib, with a slightly unclear distinction. Parfait is a minimalistic core library on which this could be built.
Stdlib, as Libc , have grown over the decades to provide overlapping and sometimes inconsistant features, most of which can and should be outside such a standard component.
Salama considers only that core which can not be suplied though an external gem, this is called Parfait. It only provides Array and String and an ability to access the operating system, in 100% ruby.
Full ruby stdlib compliance is not an initial project goal, but may be achieved through external libraries
