request: gcode highlighting

[marc-medley]

Request: add "G-code" syntax highlighting to prism with the language identifier of gcode.

G-code is the common name for the most widely used numerical control (NC) programming language. see Wikipedia: G-code

The implementation is really small and already exists in https://github.com/kmoser77/prismjs-reprap-gcode.

Prism.languages.reprap_gcode = {
	comment: /;.*/,
	keyword: /\b(G[\d]+|M[\d]+)\b/g,
	property: /\b(X|Y|Z|E|F|S|P|T|I|J|D|H|R|Q|N|\*)/g
};

May I ask what the * property refers to? I can't find it in the linked Wikipedia page.

[marc-medley]

/;.*/ is comment string wildcard

property…\*)… is for a checksum field that may appear at the end of the executable portion of the line:

N3 T0*57 ; This is a comment
N4 G92 E0*67
; So is this
N5 G28*22

see https://reprap.org/wiki/G-code#.2A:_Checksum

@marc-medley
Thank you!

We might as well also add strings before they destroy our comments.
