Brainfuck compiler

This a simple implementation of a Brainfuck compiler in Rust, has several modes of operation, and can be used as a REPL.

You need to have Rust installed, which is usually done via curl to get rustup (further instructions in the Rust home page), or at least rustc rust compiler with the std lib.

Brainfuck Interpreter Example scripts

This project includes several examples in many different programming languages with the same approach to making a simple brainfuck interpreter, these are purely meant to see the difference on how the same program can look very different on some languages and to highlight the importance of writing idiomatic code.

Installation

If you want to install it, after cloning the repo, you can do so with:

cargo install --path .

Usage

Everything will be explained with Cargo, but you can also use the binary if you installed it.

Build

cargo run --release -- build <file>

If you want to save the intermediate code representation, you can add the --save flag:

cargo run --release -- build <file> --save # or -s

Run

You can run the file directly like any other interpreted language would with:

cargo run --release -- run <file>

Or you can use the REPL mode with:

cargo run --release -- repl

And then you can enter your Brainfuck code, and it will be executed.

Help

If no command is given or if you use the --help flag it'll display the due help message and if the same flag is used in any of the commands it'll show relevant information too.

Example
