Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
XIDEK is an extensible interpreter development kit. It supports an interpreter and simple compiler development with a small but complete collection of reusable, extensible parsing and support modules. These modules implement standard expression and statement syntax, including control statements, symbol tables, abstract syntax trees, and simple bytecode interpreters. They can be used as a starting point for rapid development of language processors for script languages, "little languages", or domain-specific languages. Numerous documented examples show how to combine and extend the base modules into custom interpreters.
XSLT syntax highlighting is an implementation of syntax highlighting as an extension module for Java based XSLT processors (such as Xalan or Saxon). For example, if you have an article about programming written in DocBook, code examples can be automatically syntax highlighted during the XSLT processing phase.
Xye is a puzzle game in which the objective is to get all the gems in each level. The mission is not as easy as it sounds: there are traps, monsters, and very hard puzzles everywhere. The player can interact with objects in the game in a lot of ways, and some of the objects can also interact with other objects.
