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.
Data2l is a language neutral, platform neutral way for describing large sets of proprietary binary data. An example of this kind of data is car navigation data, which is about 1GB to 15GB in a typical embedded navigation. With Data2l you can easily describe almost any binary data format using primitive description blocks like basic type, array, structure, or alternative and using a functional dependency description language. Using such a description, one can generate source code optimized for certain tasks, like a lightweight data reading layer, fast querying code, or code suitable for data generation and transformation.
PHPTAL is a fast, safe, XML-based template engine for XHTML and HTML5. It implements Zope's Template Attribute Language, which has clean, concise syntax that is compatible with XML tools (no custom ugly tags), and template source files can even be previewed in Web browsers or opened in WYSIWYG editors. Templates are compiled to PHP and cached, giving great performance and taking advantage of PHP accelerators. PHPTAL by default ensures well-formed output and escapes XML-unsafe characters everywhere, which means that your pages can be completely safe against HTML-injection (XSS) without great effort. It features fine-grained caching of output, pre- and post- filters, internationalization via gettext or custom backend, creation of custom template attributes and expressions, and templates loaded from non-standard sources (e.g. databases). It supports UTF-8 well, is easy to integrate and redistribute with PHP frameworks and applications, and has an object-oriented design and a comprehensive unit test suite.
JGrit is a program that converts images from common formats (e.g. GIF, JPEG, BMP, and PNG) to source code that can be used to render the image on either the Game Boy Advance (GBA) or the Nintendo DS (NDS) system. There are already programs that do this, but none that play nicely with both Windows and Linux. It uses the grit command line tool as a backend.
CocoXml is a combination of programming language scanner/parser generator (defined by .atg) and XML language scanner/parser generator (defined by .xatg). The generated sources can be updated by updating the .atg or .xatg. Source inclusion, automatic indentation, and backslash newline are supported. Some real usable scanners and parsers are provided for CExpr, JSON, Kconfig, patch, and RSS.
