Agar is a toolkit for graphical applications. It features a modern GUI system with an unobtrusive API. Agar can use different graphics interfaces, such as SDL and OpenGL, and it has been ported to numerous platforms, including game consoles and embedded systems. Agar is implemented in C, but can be used from other languages.
Akelos is an MVC framework for PHP that tries to bring the magic of Ruby on Rails to the PHP world. Akelos based applications can run on most shared hosting service providers since Akelos only requires a standard PHP installation on the server. Akelos is designed to make developers lives simpler by solving complex problems with unusual speed and productivity. Favoring "convention over configuration" leads to the creation of uniform and simpler-to-understand code.
Allegro is a multi-platform game library for C/C++ developers that provides many functions for graphics, sounds, player input (keyboard, mouse, and joystick), and timers. It also provides fixed and floating point mathematical functions, 3D functions, file management functions, compressed datafile, and a GUI.
Angel is a 2D game prototyping engine based on OpenGL and C++. It was originally made by a group of employees at Electronic Arts Los Angeles for use in a GameJam they were planning for April of 2008. Angel provides many useful functions for prototyping gameplay, including simple physics, particles, text rendering, sound, input mappings, config files, pathfinding, and Python scripting.
AntTweakBar is a small and easy-to-use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL or DirectX based graphic programs to interactively tweak them. Program variables can be linked to a graphical control that allows users to modify them. Programmers are not required to design the graphical interface by providing coordinates or by using a visual UI editor. Controls are automatically organized following an optional given hierarchy.
The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform- specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
AqBanking is a modular and generic interface to online banking tasks, financial file formats (import/export), and bank/country/currency information. AqBanking uses backend plugins to actually perform the online tasks. HBCI, OFX DirectConnect, and EBICS are currently supported. AqBanking is used by GnuCash, KMyMoney, Pecunia, AqBanking-CLI, and QBankManager.
Argyll is an ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, and film recorders, and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for a fast 8-bit raster color conversion engine as well as support for fast, fully accurate 16-bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
Artisan System is a PHP framework aimed at build Web sites and e-commerce Web software very quickly and efficiently. It supports most of the features expected in a PHP framework, along with a feature-set with e-commerce classes. The e-commerce classes will support credit card processing, other payment methods, shipping calculators and estimators, product management, customer processing, and order creation and management. Artisan System has a very fast but structured development roadmap.
Asbru Web Content Management is an easy-to-use and inexpensive Web content management system. It runs on most major Web platform operating systems, databases, Web servers, and scripting languages. It is available in three editions: Personal (for individuals), Professional (for organizations), and Hosting (for Web hosting service providers).
