BNF Grammars

I'm using this gist to collect a bunch of BNF grammars I've written, extracted, or found across the web. All of them are representations of existing languages. I found them useful, someone else might as well

Languages:

C c-grammar.bnf - An incomplete representation of the C language in BNF (from 1988, all newer versions I could find were EBNF or PEG. Let me know if you have a better one.)

Adapted from The C Programming Language, 2nd edition, by Brian W. Kernighan and Dennis M. Ritchie,Prentice Hall, 1988.

Python Wiggle Walk

This is a turtle simulation of a random wiggle walk.

Steps

1. Create 20 turtles of a random color
2. Move forward 10 steps
3. Turn randomly (from 0 to 360 in rounded.py, and any multiple of 90 in straight.py)
