binarygcode

A no_std + alloc rust library and (coming soon) binary crate to deserialise and serialise binary gcode (.bgcode) files. The binary gcode specification can be found here.

Support

Please consider supporting the crate by:

• Downloading and using the crate.
• Raising issues and improvements on the GitHub repo.
• Recommending the crate to others.
• ⭐ the crate on GitHub.
• Sponsoring the maintainer.

Functionality

The crate is still under construction. So far we have managed to complete...

Example

Examples can be found in the examples folder. Below is an example of reading the headers

use std::{
	env,
	fs::File,
	io::{BufReader, Read},
	str,
};

use binarygcode::{
	common::{BlockKind, Encoding},
	deserialiser::{DeserialisedBlock, DeserialisedResult, Deserialiser},
};
use meatpack::{MeatPackResult, Unpacker};

fn main() {
	// Create the path to the gcode file
	let mut path = env::current_dir().unwrap();
	path.push("test_files");
	path.push("mini_cube_b.bgcode");

	// Open the file and attach a reader
	let file = File::open(path).unwrap();
	let mut reader = BufReader::new(file);

	// Initialise the deserialiser
	let mut deserialiser = Deserialiser::default();

	// Initialise the read buffer. This could be reading from a file
	// or waiting for intermittent bytes from a network transfer.
	let mut buf = [0u8; 256];

	loop {
		// Read bytes into the buffer
		let read = reader.read(buf.as_mut_slice()).unwrap();
		// Exit when exhausted
		if read == 0 {
			break;
		}
		// Provide the read bytes to the deserialiser
		deserialiser.digest(&buf[..read]);

		// Loop through running deserialise on the deserialisers inner
		// buffer with it returning either a header, block or request for more bytes.
		// Or an error when deserialising.
		loop {
			let r = deserialiser.deserialise().unwrap();
			match r {
				DeserialisedResult::FileHeader(fh) => {
					println!("{:?}", fh);
				}
				DeserialisedResult::Block(b) => {
					println!("{}", b);
				}
				DeserialisedResult::MoreBytesRequired(_) => {
					break;
				}
			}
		}
	}
}
