Hi PICers and Forthers,
Just announcing a new alpha cut of Pic18Forth, available from the usual
place: http://pic18forth.sf.net
Some highlights of new version:
- added dynamic multitasker (tasks can be easily 'spawn'ed at
run time)
- added global interrupt-driven millisecond-resolution clock,
plus thread-friendly time delay routines
- more examples, better doco
- massive compiler re-work:
- 98% of compiler capability is now unbundled into separate
a-la-carte library modules - the application source
code 'bootstraps' the compiler into needed capability
by loading chosen library modules (plugins),
- simpler internal structure
- big code cleanup
What might be noteworthy to non-pic18 users is the fact that the
compiler's new structure allows for it to be retargeted to other
devices, even completely unrelated devices like AVRs, ARMs, x86 or 68k
chips.
(I'm way tempted to start on an x86 backend - there might be some value
in a vm-based forth compiler that generates compact standalone apps - as
long as I add the ability to load/invoke external system libraries).

Cheers
