Syx improvements

Hi,
some times ago i talked about my Smalltalk implementation, Syx.
These are the main objectives i reached till now:
  • Working on Windows and Linux indifferently, using the Scons build system
  • Added a very simple garbage collector and memory management
  • Added a basic plugin system
  • Introduced immediate Characters (like SmallIntegers)
  • Exception handling/ensuring
  • Image compatible with both 32bit and 64bit format
This is what's next:
  • Coalesced hash tables with consistent hash functions
  • Add system signal handling
  • Complete the basic environment
  • Implement a strong method caching
  • Use non-blocking functions for I/O
  • Foreign Function Interface (maybe FFICall?)
Here is the ChangeLog and a screenshot of Gtk+ running inside Syx

    No, FFCall, this one: http://www.haible.de/bruno/packages-ffcall.html

    There's no libffi inside MingW Gcc. However, i still don't know... really

    Bringing up the GtkWindow didn't work for me. Here's what I got:

    > GtkWindow new showAll.
    > Gtk main!
    PrimitiveFailed>>signal
    PrimitiveFailed class>>signal
    GtkWindow class>>primitiveFailed
    GtkWindow class>>primNew
    GtkWindow class>>new
    UndefinedObject>>goDoIt
    String>>doIt
    BlockClosure>>repeat
    Console>>run
    Console class>>run
    >

    I checked it out of svn a few minutes ago. Will try more. Ubuntu 7.04, with the gtk2.0-dev and readline5-dev packages installed.

    You need to load the plugin first:

    > Smalltalk loadPlugin: 'gtk'!
