I'm excited about this, and about the book that Logan has picked out. :)

Regardless on whether you plan to read along, please feel free to drop in on
the #lucy_dev IRC channel during any of these virtual get-togethers and say
hello.  There are a lot of you that I'd love to meet or to introduce to each

The book club format is something I've participated in numerous times before.
Right now at Eventful there's a group of us going through "Pro Git" by Scott
Chacon; since it's directly applicable to our daily work, the rewards for
learning the material are tangible and immediate.  It's great to have a
similar opportunity with the Lucy community and a book I've wanted to read for
a long time!

There are three parsers in the Lucy codebase (if we exclude the
lexers/tokenizers among our Analyzers):

    * QueryParser
    * The Lemon-based JSON parser.
    * The Clownfish header parser, also Lemon-based.

JSON is a simple format which everyone already knows, so I can imagine us
pressing the JSON parser into service as example code for the chapter on
formal grammars.

The top review at Amazon provides a taste of what's in store:

    Over the years the Compilers: Principles, Techniques, and Tools (2nd
    Edition) (also knwon as the dragon book) has become the de facto standard
    for introducing compilers and related topics at universities. This is very
    unfortunate because "Programming Language Pragmatics" is in a completely
    different league and should be the one used instead. It gives the student
    (or the self taught) a complete and through overview of parsing, grammar,
    automata theory and other key language constructs. What really
    differentiates this book from others (and most notably the (in)famous
    "Dragon Book") is that it does so in a easy to understand manner and with
    lots of well written examples.
