Zyan Communication Framework simplifies development of distributed applications. It works on Windows, Linux, Mac OS, and Android platforms via .NET or Mono runtimes. It features LINQ support for three-tier applications, full duplex TCP support, traffic, compression, and encryption, transparent support for events and EBC (event-based components), and Windows and LDAP authentication support.
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.
Configurator is a configuration file parser. It allows you to use arbitrary nesting of sections. The user can define an option's default value, necessity, and semantic check. It supports single-line and multi-line comments (in C++ style). It provides common checks of options and sections, like duplication, incorrection, etc. It uses only Boost C++ libraries and ISO C++. It is header-only (does not require building) and very easy to use.
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.
