A basic C# gcode parser and interpreter.

Once you've downloaded a copy of the repository (e.g. as a git submodule), you should be able to start using the gcodes library by asking Visual Studio to add a reference to it.

If you just want to inspect a gcode program without doing any simulation you just need to run the Parser and inspect its output.

Parsing the input text takes place in two steps:

• Tokenizing, using the Lexer class to convert source text into a stream of Tokens
• Parsing, using a Parser to convert a stream of Tokens into a bunch of Gcode objects.

public static void ParseGcodeFile(string filename) {
	string src = File.ReadAllText(filename);

	var lexer = new Lexer(src);
	List<Token> tokens = lexer.Tokenize().ToList();

	var parser = new Parser(tokens);
	List<Code> gcodes = parser.Parse().ToList();

	// do something with the gcodes
}

Note: For convenience, Parser also has a constructor which accepts a string and will tokenize everything for you.

There is no guarantee that every argument is provided to a gcode, therefore if you want to fetch an argument's value (e.g. X or feed rate) you can use the ValueFor() method. This will search the arguments provided to a particular gcode for the specified ArgumentKind, and return its value.
