Functional programming is so called because a program consists entirely of functions. The main program itself is written as a function which receives the program's input as its argument and delivers the program's output as its result. Typically the main function is defined in terms of other functions, which in turn are defined in terms of still more functions until at the bottom level the functions are language primitives.
John Hughes-- Why Functional Programming Matters
Phoenix enables Functional Programming (FP) in C++. The design and implementation of Phoenix is highly influenced by FC++ by Yannis Smaragdakis and Brian McNamara and the BLL (Boost Lambda Library) by Jaakko Jaarvi and Gary Powell. Phoenix is a blend of FC++ and BLL using the implementation techniques used in the Spirit inline parser.
Phoenix is a header only library. It is extremely modular by design. One can extract and use only a small subset of the full library, literally tearing the library into small pieces, without fear that the pieces won't work anymore. The library is organized in highly independent modules and layers.
The Phoenix library is organized in logical modules. This documentation provides a user's guide and reference for each module in the library. A simple and clear code example is worth a hundred lines of documentation; therefore, the user's guide is presented with abundant examples annotated and explained in step-wise manner. The user's guide is based on examples: lots of them.
As much as possible, forward information (i.e. citing a specific piece of information that has not yet been discussed) is avoided in the user's manual portion of each module. In many cases, though, it is unavoidable that advanced but related topics not be interspersed with the normal flow of discussion. To alleviate this problem, topics categorized as "advanced" may be skipped at first reading.
Some icons are used to mark certain topics indicative of their relevance. These icons precede some text to indicate:
