Allegro is a free open source software library for video game development, with functions for basic 2D graphics, image manipulation, text output, audio output, midi music, input and timers, as well as additional routines for things like fixed-point and floating-point matrix arithmetic, unicode strings, file system access, file manipulation, data files, and (limited, software-only) 3D graphics.

History Initially standing for "Atari Low-Level Game Routines" [1], Allegro was originally created by Shawn Hargreaves for the Atari ST in the early 1990s. However, Shawn abandoned the Atari version as he realized the platform was dying, and reimplemented his work for the Borland C++ and DJGPP compilers in 1995. Support for Borland C++ was dropped in version 2.0, and DJGPP was the only supported compiler. As DJGPP was a DOS compiler, all games which used Allegro therefore used DOS. Around 1998, Allegro branched out into several versions. A port to Microsoft Windows, WinAllegro, was created, and also during this time, a Unix port of Allegro, XwinAllegro, was created. These various ports were brought together during the Allegro 3.9 WIP versions, with Allegro 4.0 being the first stable version of Allegro to support multiple platforms. The current version of Allegro supports Unix (Linux, FreeBSD, Irix, Solaris, Darwin), Windows (MSVC, MinGW, Cygwin, Borland C++), BeOS, QNX, Mac OS X, and DOS (DJGPP, Watcom). Shawn Hargreaves is no longer involved with Allegro.

The current version of Allegro is 4.2.0 stable. Following this release, the development roadmap calls for a shift to the so-called "new" API branch (also known as the 4.3.x series), which will feature a modern and revised API, as well as full hardware acceleration. (The 4.2.0 version only can use HW acceleration for certain 2D drawing primitives, and usually only when using Windows/DirectX.) Backwards compatibility will be maintained through an extra API layer emulating the old API. Work on the new API branch started in parallel with the 4.1.x series, meaning that a lot of the codebase has already been rewritten. The 4.2.x series will be the last utilising the old code base.
For hardware accelerated 3D and 2D acceleration on Linux and MacOS X, AllegroGL and OpenLayer are available. They are two add-on libraries that use OpenGL for accelerated graphics routines and use Allegro for all other gaming needs.

Comparison to other libraries There are many other free libraries with overlapping functionality to Allegro around such as ClanLib. The most popular of them is Simple DirectMedia Layer (SDL). Allegro is older than SDL, but SDL is in more widespread use. Both Allegro and SDL work under systems such as Linux and other UNIXes, Windows, QNX, BeOS and Mac OS X. Additionally, Allegro works under DOS, while SDL works on older versions of Mac OS and Amiga. SDL also has been ported to console game systems/handheld game systems such as PS2, Xbox, Dreamcast, GP32, et al.
