Brainfuck Interpreter in Go

A Go-based interpreter to read and run Brainfuck programs in pure Go in the simplest way. (With a C-generator Brainfuck interpreter written in Brainfuck)

Using

$ CGO_ENABLED=0 go build -o bf .
$ ./bf

Compiler

./bf compiler.bf

After running the program, the program will wait for you to type your BF program, finally you can easily type any character you want. like x to finish and generate C-code.

Brainfuck

Brainfuck is an esoteric programming language created in 1993 by Urban Müller.

Notable for its extreme minimalism, the language consists of only eight simple commands, a data pointer and an instruction pointer. While it is fully Turing complete, it is not intended for practical use, but to challenge and amuse programmers. Brainfuck requires one to break commands into microscopic steps.

The language's name is a reference to the slang term brainfuck, which refers to things so complicated or unusual that they exceed the limits of one's understanding as it was not meant or made for designing actual software but to challenge the boundaries of computer programming.
