Free pykde software for linux

PyKHTML is a Python module for writing website scrapers/spiders. Whereas traditional methods focus on writing the code to parse HTML/forms themselves, PyKHTML uses the excellent KHTML engine to do all the trudge work.

It therefore handles webpages very well (even the severely crufty ones) and is pretty darn fast (implemented in C++). As a bonus the module handles JavaScript and cookies transparently.

How?

PyKHTML requires PyKDE 3 (and hence in turn PyQt 3 + KDE libs). If you would like to run PyKHTML on servers without an X display then Xvfb is required. Fortunately these requirements should come bundled with most modern Linux distributions, and support for Windows/Mac should appear in the next few months.

Show me some code

Okay. Here is an example (one of many examples included in the bundle) that scrapes the title and navigation from this page, with excessive commenting to give you a feel of what programming with PyKHTML is like:

import pykhtml

PyKHTMLUrl = "http://paul.giannaros.org/pykhtml"

def extractBitsFromPage(browser):
# getElementsByTagName returns a generator, so we convert
# to a list and access the first element
title = list(browser.document.getElementsByTagName("title"))[0]
print "Title:", title.text
# Get the text of the navigation items
navigation = []
# First get the container of the list items...
navigationElement = browser.document.getElementById("navigation")
# ... and then loop over the li elements we find
for listItem in navigationElement.getElementsByTagName("li"):
# Inside the list item is an anchor
anchor = listItem.children[0]
# And the text inside the anchor is what we want
navigation.append(anchor.text)
print "Navigation:", " | ".join(navigation)
# Stop here, were done
pykhtml.stopEventLoop()

def main():
browser = pykhtml.Browser()
# the browser is passed as a parameter to extractBitsFromPage
# when it is called (when the page has loaded)
browser.load(PyKHTMLUrl, extractBitsFromPage)
# kick things off
pykhtml.startEventLoop()

main()

FARnodes is a protocol simulation and execution environment. FARnodes project comes with a command-line frontend, a protocol code distribution manager, and a statistical analyser based on PyKDE.
Example algorithms like Consensus and several other small tools and a big chunk of documentation make this a suitable entry-level software for people who have some interest in this (somewhat academic) area.
Main features:
- High portability and easy extensibility of the framework due to a pure Python implementation.
- Protocols can assume either fully synchronous or asynchronous systems, or one of FAR (Finite Average Response times) or PS (Partial Synchrony).
- Channels can exhibit unreliable or stubborn behaviour.
- Failure detectors include EA-FD and PS-FD, both eventually perfect, but others can be added.
- Simulations can expect a virtual timer and can be saved and reloaded in many cases.
- Tools for remote execution and graphical data analysis.

Panzis Lyrics is a collection of amaroK lyrics plugins.
Panzis Lyrics amaroK-script requires amaroK 1.4 and pyKDE!
Contens:
- Local Lyrics, see also: http://www.kde-apps.org/content/show.php?content=37981
- Lyrix.at
- Leos Lyrics

KAOMP can be used to download songs from AllOfMp3. The songinformation can be retrieved from the MusicBrainz database to complete the song tags.

It is written in Python and requires pyCurl, pyQT and pyKDE, MusicBrainz, TunePimp and taglibs.

SKaz is a SuperKaramba interface to Azureus (Bittorrent client). Shows most useful info/controls in a simple desktop interface.
Main features:
- Graphical progress bar with ability to Start/Stop/Remove downloads
- Displays ETA for downloads and upload rate for seeds
- Displays Total Download/upload rate for Azureus
- Clicking on the health icon of a torrent shows more detailed information, as well as basic controls
- Clicking the torrent name opens the downloaded file/dir in your preferred application. You must enable "Use generic classes" under advanced settings in the configuration of the XML over HTTP plugin (needs Azureus 2.4.0.0 and PyKDE)

KatchTV is an "Internet TV" application for KDE. KatchTV makes it easy to subscribe to "TV" channels from all over the internet in the form of podcasts, so that you can browse channels, download shows, and watch them, all from one convenient interface.

KatchTV is very similar to Democracy TV, but focuses on KDE integration, using KHTMLPart and embedded players such as kaffeine. Its much faster, and lighter on resources if you run a KDE desktop without GTK apps.

Installation is easy, as long as your distro has PyKDE, PyQt, and Kaffeine. Just untar to some directory like /usr/local, and run the KatchTV program. You can also make a symlink to that executable from a directory like /usr/local/bin, and KatchTV will work out where to find its files.

Comments welcome; let me know if youve any problems using it.

SoundMania is a desktop applet designed for the purpose of displaying information and control of known media players.
It supports amaroK, noatun, XMMS, rhythmbox, KsCD, kaffeine, JuK, Kaboodle, BMP.
It works best with superkaramba 0.37 or higher.)
For XMMS support you need to install the xmmsctrl package (which depends on xmms-devel):
http://user.it.uu.se/~adavid/utils/
Different backgrounds to make the theme compatible with most popular ones.
Main features:
- Displays artist name, song title, remaining time, bitrate(amaroK & JuK only) of the playing song.
- Displays the album cover if available (Look at the screenshots!). Rounded edges option (requires ImageMagick)
- Interactive progress bar: You can browse through the song by clicking on the progress bar.
- Control buttons
- Mouse wheel over the applet controls the volume.
- Menu choice to switch between the players.
- Auto-select player feature.
- Menu choices to display the album cover, shadow text, change the text and progressbar colors, the background and buttons.
- Customizable the text color.
- Customizable layout (limited)
- Configuration window (requires PyQt, or kdebindings).
- Detection of PyKDE (or kdebindings) libraries. If found the script does native dcop calls, which take less CPU.
- Optional Fetch albumcover for the currently playing track from internet function. This saves the albumcovers in the ~/.albumcovers directory. When using amarok this function first checks amarok for the albumcover. In order to download an albumcover from internet, the artist and album name infos must be correctly entered in the id3 tag of the track.

Cbar project is a Konqueror sidebar with the following goals:
- Provide contextual information when browsing directories, similar to Metabar and Windows sidebar.
- Easy to extend by providing extensions in the form of scripts.
- Cross-platform (thanks to using scripts, which are platform-independent).
Cbar wouldnt be created without many other people. Thanks go to:
- KDE team - for creating such a great and extensible system as KDE.
- Phil Thompson - for creating Python bindings for Qt (pyQt) and KDE (pyKDE).
- Sebastian Sauer - for creating Kross scripting engine for KDE.
- Florian Roth - for creating Metabar.
- OU - for everything.
Main features:
- Pluggable scripts for selected items, selected folder, theme and script loading.
- Konqueror sidebar module.
- Preloading plugin for fast loading.
- Basic scripts showing capabilities of Cbar:
- Image preview
- Other places
- File details
- Eject media
- Generic Cbar library with scripting capabilities, which can be embedded in other modules.
