encode and decode strings into and from application/x-www-form-urlencoded The application/x-www-form-urlencoded format encodes a ordered data sets of pairs consisting of a name and a value, with pairs separated by ampersand or semicolon and names and values separated by the equal sign. Space characters are replaced with plus sign and any characters not in the unreserved character set is encoded using the percent-encoding scheme also used for resource identifiers. A percent-encoded octet is encoded as a character triplet, consisting of the percent character "%" followed by the two hexadecimal digits representing that octet's numeric value.

Beautiful Soup parses arbitrarily invalid XML- or HTML-like substance into a tree representation. It provides methods and Pythonic idioms that make it easy to search and modify the tree. A well-formed XML/HTML document will yield a well-formed data structure. An ill-formed XML/HTML document will yield a correspondingly ill-formed data structure. If your document is only locally well-formed, you can use this library to find and process the well-formed part of it. The BeautifulSoup class has heuristics for obtaining a sensible parse tree in the face of common HTML errors.

This is a little WWW-proxy that can communicate over both IPv4 and IPv6. It's primary use is as stub-proxy between a IPv4-only browser and the rest of the (v4 and v6) Internet. This proxy is meant to run on a client machine as frontend to an IPv4-only browser and not to serve a large number of clients. If you need the latter you're much better off with a full-fledged proxy like squid. This program is based on same code copyrighted by the Junkbusters Corp.

This extension makes all html textareas into a very stripped-down version of Vi[m]. It's modal, supports infinite undo, has register support, search, visual mode, and various movement and editing commands There's a lot yet to implement, but I've tried to cover all the basics that you'd use every day to type an email, edit a wiki page, etc. That being said, you'll note that the version number hasn't hit 1.0 yet. If you like the power of ItsAllText, but want something a bit lighter-weight, give it a try.

LessTif is a API compatible clone of the Motif toolkit. Currently LessTif is partially implemented with most of the API in place. Both Motif 1.2 and Motif 2.0 libraries are built and installed. By default, the 1.2 library is used because it is a more complete implementation of the Motif 1.2 API. The Hungry Programmers, the people writing LessTif, have adopted a naming scheme where an even minor number indicates a stable release of the libraries and an odd number is a development release. *Ports will be made for even number releases only.*

Unique is a library for writing single instance application. If you launch a single instance application twice, the second instance will either just quit or will send a message to the running instance. Unique makes it easy to write this kind of applications, by providing a base class, taking care of all the IPC machinery needed to send messages to a running instance, and also handling the startup notification side. Unique aims to replace the BaconMessageConnection code that has been copied by many projects and the code using Bonobo and D-Bus.

When programming Tk, it's almost always a good idea to keep a reference to the widgets that you created in the interface. Most of the time, a simple hash is enough; but it is usually wrapped up in methods to make the hash private to the window object. And of course, those methods are duplicated in all modules, under a form or another. Since duplication is bad, this module implements a Moose role implementing those methods once and forever. This implies that your class is using Moose in order to consume the role.

Libsx is a library of code that sits on top of and to the side of the Athena widget set. Its purpose is to make writing X applications *much* easier. To accomplish this, libsx encapsulates a large portion of the uglier details that arise while programming in X and it fills in some gaps that exist with the Athena Widget set (such as a widget for drawing graphics); libsx tries to simplify the common case down to a single function call with only a few arguments.

Metisse is an experimental X desktop with neat OpenGL features. It consists of a virtual X server called Xmetisse, a special version of FVWM, and a FVWM module FvwmCompositor. Metisse was designed with two goals in mind. First, it should make it easy for HCI researchers to design and implement innovative window management techniques. Second, it should conform to existing standards and be robust and efficient enough to be used on a daily basis, making a suitable platform for the evaluation of the proposed techniques.
