问题
Editing lex or yacc files with Emacs is a nuisance: if I use C mode the indenting goes wrong, and if I don't use C mode I can't use indenting. Does anyone have a trick, a method, or an editing mode to get around it?

It's not entirely what you want but there is a very excelent Bison mode for Emacs.

This is a better link:

Since Yacc and bison are so closely related I don't find it lacking too much. Though I do most of my work with Antlr anymore.

Looks like Matz (of Ruby fame) wrote a yacc(/bison) mode. Have a look at http://www.rubyist.net/~matz/a/yacc.el

I generally toggle between Makefile mode, text mode, and C mode depending on which line I am on. If you want better, you should write the mode!
