Using Spirit X3, Part I

Explore the fundamentals of Spirit X3, a powerful parsing library for C++14, in this comprehensive conference talk from CppNow. Dive into the world of domain-specific embedded language (DSEL) parsing as Michael Caisse and Joel de Guzman guide you through building grammars, selecting appropriate data structures, and implementing useful patterns. Learn how to capture line numbers, handle context on failures, and solve real-world parsing problems. Discover why Spirit X3 compiles faster, runs faster, and offers a more user-friendly experience compared to its predecessor. Gain insights into concepts such as rules, parsers, character parsers, combining parsers, and attribute synthesis. Master techniques like sequence, pipe, evaluate, clean star, look ahead, and difference expectations. By the end of this talk, you'll be equipped to employ Spirit X3 for all your parsing needs in modern C++ development.
