“Boostache Exposed : the internals of Boost's template engine"
summary
Boostache is a C++11 template engine that parses Mustache and Django-like templates with a Boost.Spirit parser, compiles them to a small set of compiled VM intrinsics (render, for-each, if/else, select, etc.), and applies those against user data via category-based type dispatch (sequence, associative, variant, optional, plain). It uses Fusion-adapted structs and an extended-variant for recursive models, offers extension points for render/test/for_each/context, compiles templates ahead of generation for speed, and partials and some context-walking features are still unfinished.
