crustyBASIC - a BASIC cross-compiler for retro machines

crustyBASIC is a BASIC cross-compiler for 80s systems. It compiles BASIC source into native machine code. It runs on Windows, MacOS, and Linux.  NOTE: this is a WIP, but is being very actively developed/improved.

Currently supported machines are: 

• Apple ][ series
• Atari 8-bit (inc 5200), 2600 VCS
• Commodore 64, Vic-20, Plus/4
• TRS-80 Color Computer 1/2/3
• Nintendo - NES
• MSDOS 16 bit

Some are a little further along than others. More will be added in the future.  Lots of example code is included to get you started.

• Compiles BASIC to native machine code for speed
• Options for speed vs size, carts, math libs, etc
• Flexible syntax that can be tailored with @REWRITE and @REWRITE_EXPR
• Modularity supported by @INCLUDE, pull in files, resources
• Portable APIs (TILE, MISSILE, GRAPHICS, CELL, IMAGE, INPUT, SOUND, etc) - write once and run multiple on systems
• Support for compiling old BASIC listings, including tokenized

Quick Start

@OPTION TARGET c64
CLS
POSITION 0, 0
PRINT "HELLO, WORLD!"

Compile to assembly:

crustybasic compile hello.cbs -o hello.s

Build a runnable .prg in one shot:

crustybasic build hello.cbs -o hello.prg

Full usage guide and language reference included as well as lots of example code.  Bug reports/feature requests can be posted here in the forums or at https://github.com/bsturk/crustybasic
