# BFC - Brainf*ck compiler

A Brainf*ck compiler for Linux.

`bfc` translates Brainfuck into C and immediately feeds it into GCC, producing small standalone ELF executables. No interpreters, no virtual machines, no runtime dependencies.

## Build the compiler

Just one command:

`make`

## Build a brainfuck program

Just one more command:

`cat file.bf | ./build/bfc > output`

Then running the program is as simple as:

`./output`


## How it works

Brainf*ck source -> Lexer -> Parser -> AST -> C codegen -> GCC -> ELF executable

A simple Hello World! program is about 9.3kb big.

## Limitations

* Linux only
* Soft-requires GCC (could be substituted for something else)
* Finite memory tape (30kb)

## Why?

Because interpreters suck.

Also because turning Brainf*ck into an ELF executable is just objectively fun.
