# gyb

A bytecode interpreter for the Garter & Gasm programming languages

## Purpose

gyb is intended to function as a portable bytecode interpreter.

gyb's architecture is designed to be close-enough to a real machine

that an assembly language designed to target this bytecode can be 

translated to real machine-code somewhat trivially.

## Implementation

gyb is based on a "ture", 

a register-based turing computer

that runs just the process and has wrappers for common syscalls.

It has a very limited instruction set

and it's bytecode is intended to

resemble RISC-V and x86-64. 

gyb is also written in C, and will stay that way.

I plan to make *alternative versions* so that there's

more options for bootstrapping the Garter compiler-chain,

but I think having a version of gyb written in C

at every step in its life-cycle will be really important

to the accessibility of the language as a whole.

## Limitations and Scope 

gyb is only intended to run on 64-bit machines,

and building a version that runs on 32-bit computers 

isn't really in my plans. 

Additionally, the gyb interpreter can only handle

a small subset of system calls.

This program is intended to function

as part of the Garter cross-compilation stage,

and to act as a target for Gasm assembly.

Anything beyond those two goals is outside the scope of this project.
