自动生成的Vim和Emacs的BNF语法着色

Of course, converting a context-free grammar to a regular grammar is not possible in the general case; however, practical languages are highly regular (otherwise regex-based syntax highlighting systems like vim and emacs wouldn"t work at all!) Autohighlight generates vim and emacs syntax highlighting from a BNF grammar and a description of which terms should be highlighted which colors. This project originated from a student collaboration between Scotty Allen and Scott Williams at the University of Colorado in 2006.
