Are there any good lexer and parser libraries (like flex/bison) for D?  If not, how much work would be involved in using flex and bison and wrapping it to D?  How straightforward is it to pass a struct from C to D (the documentation http://dlang.org/struct.html just says that D structs go directly to C -- the other way holds too if the C side is written in a certain way, but gives no examples of what is needed on both sides)?

A POD struct in D is interchangeable with C structs, both ways. You just have to make the declaration of the struct in both languages.

There is also http://www.semitwist.com/goldie/ but I did not use it.

If you like Parser Expression Grammar there's Pegged: https://github.com/PhilippeSigaud/Pegged

Better to go to [1], where I combined that series of posts into a single article and updated a few things, too.
