The Rust Forth Compiler

This tool allows me to write Forth "source" that will get transpiled to an assembler dielect. It currently supports AT&T-style (so, UNIX, Linux, etc.) and 64tass for the 6502 and similar family.

Installation

cargo build

Then run in place (or with cargo run) or cargo install it (I guess) or whatever completes you.

Invocation

rfc --arch ca6502 -d ARCH_65816,ARCH_WDC fth_main.fs > fth.s

The above will cause ARCH_65816 and ARCH_WDC to be defined so that the Forth compile-time word [DEFINED] can test for them (or any arbitrary string). As an example:

[DEFINED] ARCH_6502 [IF]

include fth_core_6502.fs

[THEN]

[DEFINED] ARCH_65816 [IF]

include fth_core_65816.fs

[THEN]

Caveats

This isn't a full Forth-2012 or DPANS94. It's a way to write a Forth in Forth instead of hand-editing assembler files.

I'm working on rudimentary vocabulary support but that is not yet done.
