soml was updated to have a typed ast layer to make programatic creation easier this brings LOTS of syntax change with it, that does not really mean anything at all All tests pass again so back to the same |

Salama
Salama is about native code generation in and of ruby.
It is probably best to read the The Book first.
The current third rewrite adds a system language, with the idea of compiling ruby to that language, Soml. The original ruby parser has been remodeled to parse Soml and later we will use whitequarks parser to parse ruby. Then it will be ruby --> Soml --> assembler --> binary .
Done
Some things that are finished, look below for current status / work
Soml
A working of the system language is done. It is strongly typed, but leans more towards ruby style syntax.
Completely object oriented, including calling convention. Not much slower than c.
A runtime: Parfait
In a dynamic system the distinction between compile-time and run-time is blurs. But a minimum of support is needed to get the system up, and that is Parfait
Interpreter
After doing some debugging on the generated binaries i opted to write an interpreter for the register layer. That way test runs on the interpreter reveal most issues.
Debugger
And after the interpreter was done, i wrote a visual debugger. It is a simple opal application that nevertheless has proven great help both in figuring out what is going on, and in finding bugs.
Status
Having finished Soml, it's time to compile ruby to it.
This will mean more work on the type front.
Stary sky
Iterate:
- more cpus (ie intel)
- more systems (ie mac)
- more syscalls, there are after all some hundreds
- A lot of modern cpu's functionality has to be mapped to ruby and implemented in assembler to be useful
- Different sized machines, with different register types ?
- on 64bit, there would be 8 bits for types and thus allow for rational, complex, and whatnot
- Housekeeping (the superset of gc) is abundant
- Any amount of time could be spent on a decent digital tree (see judy). Or possibly Dr.Cliffs hash.
- Also better string/arrays would be good.
- The minor point of threads and hopefully lock free primitives to deal with that.
- Other languages, python at least, maybe others
- translation of the vm instructions to another vm, say js
And generally optimize and work towards that perfect world (we never seem to be able to attain).
Contributing to salama
Probably best to talk to me, if it's not a typo or so.
I do have a todo, for the adventurous.
