Roo - Unofficial Goo Format Parser for Elegoo 3D Printers

Roo is a Rust library that enables you to parse .goo files, the proprietary format used by Elegoo 3D printers. This library is not officially associated with Elegoo and is a community-driven project.

Roo is inspired by the UVTools project, and is essentially a rewrite of the GooFile.cs class found in that project. The purpose of this library is to make it easier for Rust developers to work with .goo files.

Installation

To use Roo in your project, add the following to your Cargo.toml file:

[dependencies]
roo_parser = "0.1.0"

Then run cargo build to download and compile Roo.

Usage

Here is a basic example of how you can use Roo to load and count the layers in a .goo file:

use std::fs::File;
use roo::Roo;

fn main() {
    // Specify the path to your .goo file
    let path = "/path/to/your/file.goo";
    
    // Open the file
    let file = match File::open(&path) {
        Err(why) => panic!("couldn't open {}: {}", path, why),
        Ok(file) => file,
    };

    // Create a Roo object from the file
    let mut roo = Roo::from_file(file).expect("Failed to parse the .goo file");

    // Iterate over the layers in the .goo file
    let mut layer_count = 0;
    while let Some(layer) = roo.next() {
        println!("Layer {}: {:?}", layer_count, layer);
        layer_count += 1;
    }

    println!("Total layers: {}", layer_count);
}

In this example, we open a .goo file, create a Roo object from it, and then we iterate over each layer in the file, printing it out and incrementing a count. At the end, we assert that the count is 32, which is the expected number of layers in our test file.
