nyu is a combination of modern academic approaches to parsing formal grammars from PEGs and expression grammars that represents the new state of the art in parser generators. nyu grammars are written in a powerful language based on PEGs (parsing expression grammars) but with modifications to allow both the AST and the parser to be specified intuitively in a single grammar. nyu outputs parsers that take advantage of the chilon::parser meta-programming library for C++. The generated parsers are almost as concise and readable as the input grammars, yet perform as well as hand-written C code. nyu ASTs are built using tuples, variant types, and lists, and allow self referential parsers and AST nodes to be manipulated. Advanced features such as hashed containers and grammar inheritance are also possible and well tested. nyu is currently powerful enough to deal with complex grammars and bootstraps its own parser.
Thumbnailator is a thumbnail generation library with a fluent interface for Java. It simplifies the process of producing thumbnails from existing image files and image objects by providing an API which allows for fine tuning of thumbnail generation, while keeping the amount of code that needs to be written to a minimum.
The Open Game Libraries is a collection of separately usable C++ libraries for creating games. It provides OpenGL window management, zip file management, OpenAL audio management, a developer console window, input management, bitmapped fonts with Unicode and kerning support, image loading and saving, model loading and importing, and generic classes and objects for game development such as math and text processing.
Anchor automatically adds curly braces and semicolons to code written in various programming languages, saving typing and making programs easier to read. It lets you pretend to be coding in Python or Lua while actually writing standard C, Java, PHP, C++, .NET, C#, or D. A script may generate files in the target language and invoke the compiler. An example bash script integrates with TCC to make runnable "scripts" with the speed of C. The scripts are easily modified to target another compiler or interpreter.
LZHAM is a general purpose lossless data compression library that borrows many ideas from LZMA, but purposely makes several key tradeoffs that favor decompression speed over compression ratio. LZHAM's compression ratio is typically within .5% of LZMA, but decompresses 2-3 times faster. LZHAM's compressor is heavily threaded in a way that does not sacrifice compression ratio. The decompressor supports streaming and memory to memory decompression, and is designed to be particularly fast on embedded devices, handhelds, and game console platforms.
aime is a simple, C-like programming language and an interpreter, both designed to be embeddable in applications. The language is straightforward, trivial, and direct. Its syntax is simpler than that of C, while still providing for full object management, higher order functions, and references. The interpreter is secure and expressive, allowing comprehensive control over program execution and providing powerful methods of application integration.
SharpTAL compiles XML-based templates to .NET assemblies. It contains a complete implementation of the Zope Page Templates (ZPT) language, a system which can generate HTML, XML, or plain text output. ZPT is formed by the Template Attribute Language (TAL), the Expression Syntax (TALES), and the Macro Expansion Template Attribute Language (METAL).
