Installation

Pull this module

go get -u github.com/ronnathaniel/brainfuck.go

Build executable from source

cd ~/go/src/github.com/ronnathaniel/brainfuck.go
go build .
mv brainfuck.go /usr/local/bin/brainfuck

Usage

This compiler can be used both in-line code and in the command line. Simple integrations allow for Used-From-Anywhere.

CLI

On the command line side, this interpreter can be stored as a quasi-executable, like gcc.

Run brainfuck, pass in BF source files as args. Source files should end with extensions .b or .bf

brainfuck hello.bf

interprets and optimizes hello.bf before computing the logic. Input is retrieved from stdin and Output pushed to stdout.

Optionally pass in a string from the command line.

brainfuck -c "++[>+<-]"

Inline

Compiling within code is easy. The Exec function will parse, optimize, compile, and run any string of BrainFuck logic.

The function has a signature of

func Exec(inputRaw string) 

allowing it to be called from anywhere.

import "github.com/ronnathaniel/brainfuck.go/brainfuck"

brainfuck.Exec(">++++[+>+++>>+<<<-]")

Open source files with a supplied OpenFile function. Pass it a relative string path.

fuckRaw := brainfuck.OpenFile("<PATH/TO/SRC>.bf")
brainfuck.Exec(fuckRaw)

Configurations

Enable debugging logs by setting the DEBUG flag.

brainfuck.DEBUG = true

The default tap size is set to 500. Override it with the TAPE_SIZE_DEFAULT flag.

brainfuck.TAPE_SIZE_DEFAULT = <NEW-SIZE: uint32>
