go-bf

⚠️ Care! Currently, this project only works on x64 macOS.

Brainfuck simulator and compiler (currently only for macOS) written in Go.

Prerequisites

For Development (and simulation):

• go installed on your system
• make installed on your system

For Compilation:

• macOS (for now - sorry Linux)
• NASM in your path
• ld in your path

Usage

Clone this repo and build the current version via

$ make release

You can now use the compiled executable under ./bin/darwin_amd64/go-bf. It accepts several command line options:

• -h: display a help menu
• -f <filename>: specify a file to simulate/compile
• -c: enter compilation mode (currently macOS only)
• -o <path>: specify an output directory (where all temporary and helper files are stored)

How it works

go-bf first lexes the provided file and removes all invalid/unimportant tokens. Then, it parses the lexed tokens and tries to build a structure similar to regular ASTs. On basis of this AST-like structure, it then generates NASM and compiles it.
