Here’s another cool Spirit talk. This time from Bryce Alexander Lelbach:

utree, a recent addition to the Boost.Spirit codebase, is a generic data structure designed to represent abstract syntax trees. Bindings to Qi and Karma make utree a powerful tool for parser and generator development with Boost.Spirit. This presentation would demonstrate the usage of utree and Spirit to build and manipulate an abstract syntax tree for four parsing/generating use cases: XML, symbolic expressions, JSON, and C-like source code. The details of utree’s integration with Spirit and their implications for writing utree-centric Spirit parsers and generators would be discussed. Additionally, design patterns for compiling a utree AST to other internal representations (DOM tree for XML, function tree for a Scheme-like language for symbolic expressions, associative arrays for JSON objects, a simple VM bytecode for mini-C source code) would be covered.
