Line number in program about pygcode

[fragmuffin]

@TurBoss thanks for the issue!

My CAM software doesn't generate line numbers, so I hadn't picked this problem up yet.

Workaround

define the following class (anywhere)

import pygcode    

class GCodeLineNumber(pygcode.gcodes.GCode):
    @classmethod
    def word_matches(cls, w):
        return w.letter == 'N'
    word_letter = 'N'
    word_value_configurable = True
    exec_order = 0

but before that works, you'll have to modify a line in gcode.py from:

if (not exhaustive) and (word.letter not in 'GMFST'):

to

if (not exhaustive) and (word.letter not in 'GMFSTN'):

If you're interested

The issue is that the parser pulls all words (<letter><number>) out of the gcode string, then attempts to bind them as parameters to the closest valid gcode to the left of it.
Anything that remains (in your case, N10) is considered to be a parameter to a modal motion gcode (eg: G0)...
So what this is saying is that G0 N10 isn't a valid code, which it isn't... but that's because I haven't assigned N codes to be their own dummy gcode.

I'll be releasing v0.1.3 very soon to fix this, and some other issues.

correction: make that v 0.2.0, I'll move this lib to alpha

ok, new version is out... let me know if you have any more troubles.
