Simple gerber parser meant to be used in conjuction with the gerber-types crate

Gerber-parser

A simple gerber parser written in rust to be used with the gerber-types crate.

use std::fs::File;
use std::io::{BufRead, BufReader};
use gerber_parser::parser::parse_gerber;

// open a .gbr file from system
let file = File::open(path).unwrap();
let reader = BufReader::new(file);

// Now we parse the file to a GerberDoc 
let gerber_doc: GerberDoc = parse_gerber(reader);

// it is possible to convert to an 'atomic' representation purely 
// in terms of Vec<Command> of the gerber-types crate
let commands:Vec<Command> = gerber_doc.to_commands();

Current State

⚠️ Note: this package is still in development and does not cover the full Gerber spec

Currently missing

• All AM commands
• LM, LR, LS commands (note: these are deprecated in the spec)
• AB commands

Partial:

• The TF and TA commands only support a limited range of arguments; custom attributes will result in an error

In addition, comments in the header section of the file (i.e. unit type declaration, format specification and aperture declarations) will be placed below the header when the parsed Gerber is converted back to string via serialisation.

General to-do

• Make parsing a bit cleaner, with Result
• Reduce the number of panics
• Make error messages clearer (avoid plain unwraps in places where errors can realistically occur)
• Do proper coordinate check (compatibility with format specification)
