# 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 input.bf | ./build/bfc > output`
or:
`echo "bf string" | ./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.
