I/D Machine

An implimentation of both the 2-instruction and OISC versions of https://esolangs.org/wiki/I/D_machine.

Building

zig build -Drelease-fast

Build Dependencies

• Zig
  • Tested on version 0.10.0-dev.1888+e3cbea934

Usage

./zig-out/bin/id-machine <code file> <output file>

To exit a program, dereference outside of accessible memory.

Header Byte

The first byte of the code file must be a header byte in the following format:

aaaabbbc

Where a controls the amount of cells (0x10000 * (1 + a) cells). b controls the ammount of bits ignored at the end of 2-instruction mode. If c is 0, then the code is interpreted in OISC mode, otherwise it is interpreted in 2-instruction mode.

OISC Mode

Aside from the header byte the length of the code must be a multiple of the number of bytes in your machine's word size (ex. 8 bytes on a 64-bit machine).

2-Instruction Mode

Each instruction is a bit, 0 is Increment, 1 is Dereference.
