Collection of brainfuck interpreters

Brainfuck interpreters

A collection of brainfuck interpreters in various languages.

Langues implemented

C

• Fixed stack size with no stack overflow
• Can read from stdin or a file
• Use make to compile and make debug to compile printing useful information for debugging.
• In the root directory is a slower implementation and under the c directory is faster. This uses a byte code transcompilation step and a stack layer.
• Execution time (Mandelbrot) 0m40,974s

Python

• Usage: ./brainfuck.py filename [-d -s stack_size]
• If no stack size is provided a dynamically expanding one is used.
• -d flag toggles printing debug information
• Can read from stdin or a file

JavaScript

• Usage: node brainfuck.js filename
• Reads the whole program first creating a "byte code" for execution.
• Surprisingly fast (6m16,514s)

GO

• Usage go build brainfuck.go and then ./brainfuck filename.
• Very similar to the javascript code.
• Mandelbrot time 1m48,398s

Julia

• Usage julia brainfuck.jl filename
• Uses a transcomilation step similar to the javascript implementation
• Mandelbrot time 0m54,092s, after some optimization does deliver. I might start using it for my own programs

Rust

• Usage rustc brainfuck.rs -C opt-level=3 and then ./brainfuck filename.
• As usal uses a transcompilation step similar to the other implementations.
• Mandelbrot time 0m34,147s

Planed

• ✔Python
• Lisp
• Haskell
• ✔Rust
• ✔Go
