The Automated Testing Framework (ATF) is a collection of libraries to implement test programs in a variety of languages. At the moment, ATF offers C, C++ and POSIX shell bindings with which to implement tests. These bindings all offer a similar set of functionality and any test program written with them exposes a consistent user interface. ATF-based test programs rely on a separate runtime engine to execute them. The runtime engine is in charge of isolating the test programs from the rest of the system to ensure that their results are deterministic and that they cannot affect the running system. The runtime engine is also responsible for gathering the results of all tests and composing reports. The current runtime of choice is Kyua.

CFFI, the Common Foreign Function Interface, purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package. The CFFI-SYS backend package defines a low-level interface to the native FFI support in the Lisp implementation. It offers operators for allocating and dereferencing foreign memory, calling foreign functions, and loading shared libraries. The CFFI frontend provides a declarative interface for defining foreign functions, structures, typedefs, enumerated types, etc. It is implemented in portable ANSI CL making use of the low-level operators exported by CFFI-SYS. This package is compiled with SBCL.

PEAR::XML_Serializer serializes complex data structures like arrays or object as XML documents. This class helps you generating any XML document you require without the need for DOM. Furthermore this package can be used as a replacement to serialize() and unserialize() as it comes with a matching XML_Unserializer that is able to create PHP data structures (like arrays and objects) from XML documents, if type hints are available. If you use the XML_Unserializer on standard XML files, it will try to guess how it has to be unserialized. In most cases it does exactly what you expect it to do. Try reading a RSS file with XML_Unserializer and you have the whole RSS file in a structured array or even a collection of objects, similar to XML_RSS. Since version 0.8.0 the package is able to treat XML documents similar to the simplexml extension of PHP 5.

Codeville is a distributed Version Control System. It began with a novel idea for a merge algorithm, and has grown from there. It is designed to be easy to use, and scale from small personal projects, to very large distributed ones. If you'd like to know why there's need for new merge algorithms, consider what the lead monotone developer had to say: http://article.gmane.org/gmane.comp.version-control.monotone.devel/3264 Codeville works by creating an identifier for each change that is done, and remembering the list of all changes which have been applied to each file, and the last change which modified each line in each file. When there's a conflict, it checks to see if one of the two sides has already been applied to the other one, and if so, makes the other side win automatically. When there's a non automatically mergeable version conflict, Codeville behaves in almost exactly the same way as CVS.

The definition of conform is "Adapt or conform oneself to new or different conditions". As this library is used to adapt your application to its deployed environment, I think it's rather fitting. It's also a play on the word configuration, and the fact that Conform uses an init-style configuration, maintained in a .conf file. Conform is a library for Elixir applications. Its original intended use is in exrm as means of providing a simplified configuration file for deployed releases, but is flexible enough to work for any use case where you want init-style configuration translated to Elixir/Erlang terms. It is inspired directly by basho/cuttlefish, and in fact uses its .conf parser. Beyond that, you can look at conform as a reduced (but growing!) implementation of cuttlefish in Elixir.

IPython is a free software project which tries to: 1. Provide an interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. It tries to be a very efficient environment both for Python code development and for exploration of problems using Python objects (in situations like data analysis). 2. Serve as an embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. This can be very useful both for debugging purposes and for situations where a blend of batch-processing and interactive exploration are needed. 3. Offer a flexible framework which can be used as the base environment for other systems with Python as the underlying language. Specifically scientific environments like Mathematica, IDL and Mathcad inspired its design, but similar ideas can be useful in many fields.

Generate is a text preprocessor that I originally wrote to help me write custom accounting applications based on the Progress database product. I felt that the built in wasn't useful enough so I designed a new one and implemented it. It actually started life as a package configuration and batch file generator for DOS and mutated to a simple script interpreter to replace shar file distribution. At this point it has almost nothing in common with that first program. The basic idea behind generate is to create a script which generates files. There is some simple flow control constructs but the power lies in its macro processing. I have shamelessly stolen ideas from cpp, m4, make and David Tilbrook's dtree.

Gitolite is an access control layer on top of git, which allows access control down to the branch level, including specifying who can and cannot rewind a given branch. Gitolite lets you use a single user on a server to host many git repositories and provide access to many developers, without having to give them real userids on or shell access to the server. Authentication is most commonly done using sshd, but you can also use httpd if you prefer. Gitolite can restrict who can read from (clone/fetch) or write to (push) a repository. It can also restrict who can push to what branch or tag, which is very important in a corporate environment.

Developing and debugging UIs can be a pain. When something goes wrong, it's not always obvious why. You can waste hours writing logging statements only to find out that a widget is in the wrong container, or an attribute wasn't set correctly. Developing isn't much better either. Ever spend time writing temporary code just to test a new feature, code you know you're going to throw away in an hour, and yet you end up spending the next 20 minutes debugging your temporary code? Sucks, doesn't it? What your program really needs is a good Parasite infestation. Parasite is a debugging and development tool that runs inside your GTK+ application's process. It can inspect your application, giving you detailed information on your UI, such as the hierarchy, X window IDs, widget properties, and more. You can modify properties on the fly in order to experiment with the look of your UI.

convertible provides a typeclass with a single function that is designed to help convert between different types: numeric values, dates and times, and the like. The conversions perform bounds checking and return a pure Either value. This means that you need not remember which specific function performs the conversion you desire. Also included in the package are optional instances that provide conversion for various numeric and time types, as well as utilities for writing your own instances. Finally, there is a function that will raise an exception on bounds-checking violation, or return a bare value otherwise, implemented in terms of the safer function described above. Convertible is also used by HDBC 2.0 for handling marshalling of data to and from databases. Convertible is backed by an extensive test suite and passes tests on GHC and Hugs.
