Grammar of Kitten

This is an annotated EBNF grammar of the latest rewrite of Kitten. Items marked with a dagger (†) are explained in the surrounding prose, not in EBNF.

Source Locations

The source column of a token is the offset to its first character within the line in which it appears. The indentation of a line is the source column of the first token in the line. Tab characters are illegal.

Layout

Achievement	Engine/Game	Why it's bad
storing world space positions in gbuffer	STALKER, F.E.A.R.	Depth buffer can be used to derive position saving a lot of memory bandwidth
uploaded texture upside down	Various engines, mostly Quake derived.	Difficult to debug with tools like apitrace, nsight, pix, renderdoc, etc
