Bitcoin is a peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
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.
Config4*, pronounced "config for star", is a family of configuration-file parsers. It currently provides C++ and Java implementations. It offers an incredibly flexible and user-friendly syntax and an API with powerful features not available in other configuration technologies such as XML, JSON, Java properties, or the Windows Registry. The comprehensive and easy-to-read documentation includes a getting started guide, expert tips, API reference manuals, and a maintenance guide.
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.
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.
Deva is a programming language that is small, dynamic, and has some similarities to C and Python. It is designed for embedding in C++ applications, and is also suitable for basic programming tasks. It is written to be as simple as possible, but no simpler. Deva is a multi-paradigm language: it is essentially procedural and imperative, but with support for basic functional and object-oriented idioms.
Kittens is an application container that can embed X applications and steal them from your window manager in order to provide advanced window management options to any window manager. It can tab windows together, split to show them vertically side by side, and allow applications and splits to be resized with the mouse or keyboard. It works in environments such as GNOME, KDE, and XFCE. Kittens is also ideal for managing applications without having to use a mouse.
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.
Pito is a set of C++0x header libraries to facilitate writing system call interceptor libraries based on LD_PRELOAD wrappers. The program "pito" is also provided for loading Unix commands with such wrappers. This system is capable of passing command line arguments to loaded plugins for easy configuration. Pito is supplied with a powerful system call sandbox library to prevent modifications to supplied filesystem locations and a system call logging library.
