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.

In the previous two installments of this article series (The Magical Power of Attributes in Spirit – Primitives and The Magical Power of Attributes in Spirit – Operators) we talked about the attribute handling in different constructs utilized to build parsers and generators with Spirit. We will continue this walkthrough while touching on the remaining parts: directives and non-terminals

Each operator implements its own set of attribute propagation rules. These rules define the synthesized attributes of Qi expressions and the consumed attributes of Karma expressions. As we have seen already, it is very important to understand how the synthesized and consumed attributes are formed. Parsers and generators are most elegant and efficient if they are tightly integrated with your data structures, and learning to match those to the attributes is crucial to being able to apply Spirit for your own needs.

Spirit V2.1 has been released only a couple of weeks ago. The first feedback we have gotten so far was overwhelming! Many people seem to quickly understand the concepts of the new library, being able to apply its power to their needs. We try to follow people’s comments and watch for reported problems. There is one theme recurring over and over again: attributes. This new (for Spirit) concept turns out to be the most difficult idea to understand, especially for somebody starting to work with the library.

In the good tradition of highlighting Spirits both major sub-libraries based on similar use cases I will talk about Karma today. In a previous installment (see Creating Your Own Parser Component for Spirit.Qi) I presented the steps needed to create a parser terminal. Our topic here is the creation of a new generator directive allowing to group output elements in columns.

This is another article in the series of “How To’s” providing you with shrink wrapped grammars directly usable in any project. I’m going to describe a Karma grammar you can use to generate output for quoted strings, where all contained special characters are properly escaped.

Even if it feels a bit like cheating I decided to get back to the example highlighting lists of key/value pairs I initially wrote about here. On the other hand looking at this very same problem from the standpoint of generating output allows me to highlight a couple a interesting facilities Spirit provides you with.
