- Amara
- Library for XML processing in Python, designed to balance the native idioms of Python with the native character of XML.
- Anemone
- Anemone is a Ruby library that makes it quick and painless to write programs that spider a website. It provides a simple DSL for performing actions on every page of a site, skipping certain URLs, and calculating the shortest path to a given page on a site. The multi-threaded design makes Anemone fast. The API makes it simple. And the expressiveness of Ruby makes it powerful.
- AngelScript
- The AngelCode Scripting Library, or AngelScript as it is also known, is an extremely flexible cross-platform scripting library designed to allow applications to extend their functionality through external scripts. Featuring a syntax similar to C/C++, it has been designed from the beginning to be an easy to use component, both for the application programmer and the script writer.
- AntTweakBar
- AntTweakBar allows programmers to quickly add a light and intuitive graphical user interface into graphic programs to interactively tweak them. It is a small and easy to use C/C++ library that can be readily integrated into OpenGL and DirectX applications. It targets graphical programs that need an easy way to tweak parameters and see the result in real-time like 3D demos, light inline game editors, small 3D applications, prototypes, debug facilities of weighter graphical programs, etc. 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. In most cases, only one line of code is needed to add a new variable to a tweak bar. AntTweakBar can be easily integrated with your own windowing system or with existing toolkits. Examples of integration with GLFW, SDL, GLU are provided.

- Apophenia
- 'Apophenia' is a statistical library for C. It provides functions on the same level as those of the typical stats package (OLS, probit, singular value decomposition, &c.) but doesn't tie the user to an ad hoc language or environment. It uses the GNU Scientific Library for number crunching and SQLite for data management, so the library itself focuses on model estimation and quickly processing data.
- AppTools
- The AppTools project includes a set of packages that Enthought has found useful in creating a number of applications. They implement functionality that is commonly needed by many applications
- enthought.appscripting: Framework for scripting applications.
- enthought.help: Provides a plugin for displaying documents and examples and running demos in Envisage Workbench applications.
- enthought.io: Provides an abstraction for files and folders in a file system.
- enthought.naming: Manages naming contexts, supporting non-string data types and scoped preferences.
- enthought.permissions: Supports limiting access to parts of an application unless the user is appropriately authorised (not full-blown security).
- enthought.persistence: Supports pickling the state of a Python object to a dictionary, which can then be flexibly applied in restoring the state of the object.
- enthought.preferences: Manages application preferences.
- enthought.resource: Manages application resources such as images and sounds.
- enthought.scripting: A framework for automatic recording of Python scripts.
- enthought.sweet_pickle: Handles class-level versioning, to support loading of saved data that exist over several generations of internal class structures.
- enthought.template: Supports creating templatizable object hierarchies.
- enthought.type_manager: Manages type extensions, including factories to generate adapters, and hooks for methods and functions.
- enthought.undo: Supports undoing and scripting application commands.
- Argtable
- Argtable is a freely available C/C++ programmer's library for parsing the command line arguments. Having only a few functions and a simple set of rules, it is capable of handling most aspects of command line parsing and error reporting with a minimum of fuss.
- Armadillo: C++ library
- Armadillo is a C++ linear algebra library (matrix and vector maths) aiming towards a good balance between efficiency and ease of use while staying lean. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language like Matlab î or GNU Octave. Armadillo uses a delayed evaluation approach in order to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through extensive use of recursive templates and template meta-programming.
- Aspell
- GNU Aspell is a spell checker that can be used either as a library or as an independent spell checker. It does a much better job of coming up with possible suggestions than other English language spell checkers. Other technical enhancements over Ispell include shared memory for dictionaries and intelligent handling of personal dictionaries when more than one Aspell process is open.
- Async-timeout
- Used in cases where part of the software being developed is time-sensitive, so that the code block doesn't wait too much time for certain event to complete.
- At-spi
- AT-SPI is a D-Bus based accessibility framework. It defines a D-Bus protocol for providing and accessing application accessibility information. The project includes a library for bridging the D-Bus protocol to the ATK API, allowing Gtk based applications to be made accessible. It also contains a client (AT) side library in C and a wrapper for Python.
- Atomthreads
- Atomthreads is a free, lightweight, portable, real-time scheduler for embedded systems. It is targeted at systems that need only a scheduler and the usual RTOS primitives. No file system, IP stack or device drivers are included, but developers can bolt on their own as required. Atomthreads will always be a small number of C files which are easy to port to any platforms that require threading by adding a simple architecture-specific file.
- Aubio
- aubio is a library for audio labeling. Its features include segmenting a sound file before each of its attacks, performing pitch detection, tapping the beat and producing midi streams from live audio. The name aubio comes from 'audio' with a typo: several transcription errors are likely to be found in the results too. The aim of this project is to provide these automatic labeling features to other audio softwares. Functions can be used off-line in sound editors and software samplers, or online in audio effects and virtual instruments.
- Autotrace
- Autotrace is a program which converts bitmap images to vector images. It can import images in BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick, and can output Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk
- Avl
- libavl is a collection of computer subroutines for constructing and manipulating binary trees and balanced trees. It includes unthreaded, right threaded, and fully threaded variants of AVL tree, as well as unthreaded red-black trees. It features self-test routines as well as insertion, deletion, tree count, tree copy, tree walking and traversal, search, and threading and unthreading routines. Each function has a comment describing its interface, and each step in the algoritms the program uses has a comment also. Each source code file includes a built-in test routine.
- B-Forms
- 'B-Forms' is an object-oriented PHP library for developing Webform-based applications. It supports tabular forms with multiple records of the same type being edited simultaneously, and provides security mechanism against data tampering. The library provides two base layouts that cover the the vast majority of cases. Only in very tricky form layouts would you have to write HTML code to specify the form layout. It also automatically saves and restores hidden fields. 'B-Forms' divides a script into three logical areas: form definition, data management, and form presentation. Forms have a powerful block architecture, each block typically representing a different data object within the form. Each block can be used to edit several objects at once- the library handles record management.
- BLAS
- The BLAS (Basic Linear Algebra Subprograms) are routines that provide standard building blocks for performing basic vector and matrix operations. The Level 1 BLAS perform scalar, vector and vector-vector operations, the Level 2 BLAS perform matrix-vector operations, and the Level 3 BLAS perform matrix-matrix operations. Because the BLAS are efficient, portable, and widely available, they are commonly used in the development of high quality linear algebra software, LAPACK for example.
- BRL-CAD
- BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.
- Babel
- A collection of tools for internationalizing Python applications Babel is composed of two major parts:
- tools to build and work with gettext message catalogs
- a Python interface to the CLDR (Common Locale Data Repository), providing access to various locale display names, localized number and date formatting, etc.
