Jim is a small footprint implementation of the Tcl programming language. It implements a large subset of Tcl and adds new features like references with garbage collection, closures, a built-in object oriented programming system, functional programming commands, and first class arrays. The interpreter's executable file is only 70 KB in size, and can be reduced by further excluding some commands. It is appropriate for inclusion inside existing programs, for scripting without dependencies, and for embedded systems.
Free Electron is a C++ framework facilitating reuse and integration for R&D projects such as simulation, AI, and visual effects. The core systems include dynamic plugins, a strong component model, and a fast runtime database. All these systems are highly extensible. Integration has been demonstrated with Alembic, Armadillo, Boost, DevIL, GraphViz, Houdini, JSON, Lua, Maya, ODE, OpenAL, OpenGL, OpenMP, OSG, PCRE, RakNet, SDL (image and joy), TBB, TIFF, OpenVDB, X11/GDI, and XML. General operators built with this framework can be used in Houdini and Maya (etc.) without any direct dependencies on those environments (each has a custom meta-plugin which interfaces the APIs). Builds are done with Python scripts (simple at the module level, like Jam, but in Python), and supports distcc, ccache, and gch files.
ATF is a collection of libraries and utilities designed to ease unattended application testing in the hands of developers and end users of a specific piece of software. Tests can currently be written in C/C++ or POSIX shell and, contrary to other testing frameworks, ATF tests are installed into the system alongside any other application files. This allows the end user to easily verify that the software behaves correctly on her system. Furthermore, the results of the test suites can be collected into nicely-formatted reports to simplify their visualization and analysis.
extract_url.pl is a Perl script that extracts URLs from either correctly-encoded MIME email messages or from plain text. It can be used either as a pre-parser for a URL selector (such as urlview), or as a standalone URL selector. It is very configurable, can handle URLs that have been broken over several lines in format=flowed delsp=yes email messages, and eliminates duplicate URLs. It was designed primarily for use with Mutt, but can be used by for any similar purpose. The idea is that if you want to access a URL in an email, you pipe the email to a URL extractor (like this one), which then lets you select a URL to view in some third program (such as Firefox).
Premake is a build configuration tool. Describe your C, C++, or C# software project using a simple, easy to read syntax and let Premake generate the project files for Visual Studio, GNU Make, Xcode, Code::Blocks, CodeLite, SharpDevelop, or MonoDevelop. Premake allows you to manage your project configuration in one place and still support different build systems. It allows you to generate project files for tools that you do not own. It saves the time that would otherwise be spent manually keeping several different toolsets in sync. And it provides an easy upgrade path as new versions of your favorite tools are released.
TooN is a very efficient numerics library for C++. The main focus of the library is efficient and safe handling of large numbers of small vector matrices and providing as much compile time checking as is possible. The library also works with large vectors and matrices and integrates easily with existing code. In addition to elementary vector and matrix operations, the library also providers linear solvers, matrix decompositions, optimization, and wrappers around LAPACK.
