I just put version 1.0 of my new SPL cross-compiler up for folks to
take a look at. SPL is a simple language which compiles to assembly
which is then turned into machine code by the as6502 assembler.
Download it here: http://home.comcast.net/~oneelkruns/
Some key points of the language and compiler:
1. Written in Python, will run almost everywhere
2. Comes with a library of over 100 assembly words, including ProDOS
disk support
3. Forth-like, though simpler
4. The compiler can generate 140k disk image files as output allowing
development using emulators
5. Easily modified to work with other 6502 systems
6. Documentation included
7. The compiler only outputs the code it truly needs. No large
runtime module.
I wrote this as a pet project and it seems to be working well enough
to release it for others to play around with. Of course, do let me
know if you find any bugs or if you think you'll use it for something.
