chilon::parser provides an extended PEG-like language using C++0x template meta-programming. This PEG-based language has been extended to support AST building features directly embedded into the type system. chilon::parser uses the input PEG to create the AST type at compile time using tuples, vectors, variants, custom classes, ranges, and primitive types. The AST is populated by parsers generated from the same type description at run-time.
phpx augments PHP syntax with powerful metaprogramming constructs such as mixins, class-level eval()/macros, pattern matching, annotations and interface delegation. It also implements a simple compiler for converting this extended syntax to standard PHP. The "compiled" code can be cached to disk, allowing features to be used without any runtime performance penalty.
JSONBOT is a remote event-driven framework for building bots that talk JSON to each other over XMPP. This distribution provides bots built on the JSONBOT framework for console, IRC, XMPP for the shell and WWW, and XMPP for the Google App Engine. A plugin infrastructure can be used to write your own functionality.
C++ command line parameters parser (CLPP) is a command line parameter parser with callback functions and, if necessary, type/semantic checking of values of input parameters. It uses only Boost C++ libraries and ISO C++. It is header-only (no need to build it) and very simple to use.
