OpenXAdES enables people to work with legally-binding digital signatures (primarily giving and verifying them). Legislation often defines a set of requirements that legal digital signature technologies and infrastructures must be compliant with, and OpenXAdES aims at meeting many, if not all, such requirements from different legislations.
P::Classes is a portable, high performance C++ application framework which provides many classes needed for real-world application development, emphasing on ease of use, size and stability. Its current highlights are a typesafe and threadsafe signal/slot mechanism, an I/O system including a plugin-based architecture for network-protocol transparent I/O, a plugin-based application message logging framework, classes and driver-plugins to access SQL databases, a message digest library, and classes for configuration management.
DialogBlocks is a low-cost dialog editor for the free wxWindows GUI toolkit. It helps you quickly create resizeable, portable dialogs and panels, and sophisticated wizards. The properties for each control and sizer can be edited in a convenient, consistent property editor, and C++ variables can be connected to controls by selecting a validator. It supports context-sensitive help and tooltips, image resources and inline or file-based XPMs, and editing of generated C++ code by hand. An image conversion tool, ImageBlocks, is also included.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
Sparse is a semantic parser of source files. It's neither a compiler (although it could be used as a front-end for one) nor a preprocessor (although it contains a preprocessing phase). It is meant to be a small, simple, easy to use library. Its function is to create a semantic parse tree for some arbitrary user for further analysis. It's not a tokenizer, nor is it a generic context-free parser. Context (semantics) is what it's all about: figuring out not just what the grouping of tokens are, but what the types are that the grouping implies.
Stone Three Foundation Classes (S3FC) is a software library which facilitates the rapid development of high-performance distributed computing applications. It is implemented as a number of C++ classes and functions that includes an efficient multi-threading framework built on top of POSIX threads, numerous efficient and lightweight queues, local (intraprocess) and network transports that provide object replication, secure network communications via OpenSSL, synchronization via mutexes, semaphores, or condition variables, periodic notification, an extensible and modular marshaling (serialization) system, a message passing system, an event dispatching and handling framework, local and remote event logging, and much more.
Q Engine is a cross-platform development system for games and interactive 3D applications. Its design strengths include built-in streaming, outstanding visual quality, and high-productivity development tools for deployment on Sony PlayStation 2, Microsoft Xbox, Linux, and Microsoft Windows.
tkscript is a JIT-accelerated C-like scripting language with bindings for OpenGL, SDL, SDL_net, libpng, and zlib. A plugin SDK can be used to dynamically extend the script engine with custom C functions and C++ classes. It can be used to create portable, 3D, OpenGL-accelerated multimedia applications.
