Welcome to Spirit

Spirit is a set of C++ libraries for parsing and output generation implemented as Domain Specific Embedded Languages (DSEL) using Expression templates and Template Meta-Programming. The Spirit libraries enable a target grammar to be written exclusively in C++. Inline grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.

Spirit is part of Boost Libraries, a peer-reviewed, open collaborative development effort.

Even if I sloppily call this series ‘Tip of the Day’, I by no means plan to have a tip a day.

This time I’m going to highlight the difference between three different ways to parse or generate a single character: ‘a’, lit(‘a’), and char_(‘a’).
