GUI-builder for PyQt/PyKDE
by Henning Schroeder Sept. 30, 1999

Sept. 30, 1999

Hi there, [...] I am working on a visual IDE based on the Qt and KDE bindings for Python. Therefore I implemented a small component library which fits the needs for visual development. I call the library ViPyl. It consists mainly of some wrapper classes around Qt widgets and adds property support to them. Unique and easy event handling is under development and currently not available. So it is not ready for real development yet. If you are interested int ViPyl and the GUI builder look at the following page for some screenshots and for an alpha version to download: http://www.henning-schroeder.de/en/python/vipyl/ Suggestions are welcome!

PSI - Python Script Interface
by henk_p＠my-deja.com Sept. 30, 1999

Sept. 30, 1999

This is the announcement of the PSI (Python Script Interface) version 0.01. The PSI is a FastCGI like interface between the Apache webserver and long running python scripts. The package consists of an Apache module (mod_psi) that handles client CGI requests and a simple python based framework for publishing long running CGI scripts. The purpose of PSI is to be able to use python based CGI scripts without the need to invoke the interpreter for every request, and to share some global 'state' (db connections, sessions, etc) between each request. This software is very very alpha. I am releasing this as a way to generate some comment on the design/implementation. PSI_0.01 can be downloaded from: http://huizen.dds.nl/~d50/psi_0.01.tar.gz Sent via Deja.com http://www.deja.com/ Before you buy. <A HREF="http://huizen.dds.nl/~d50/psi_0.01.tar.gz">PSI 0.0.1 (click to download as .tar.gz file)</A> - Python Script Interface; an Apache module for long-running Python CGI scripts, similar to FastCGI.

ldap-client-cgi.py 0.5.0: WWW gateway for accessing LDAP servers
by Michael Ströder Sept. 30, 1999

Sept. 30, 1999

HI! I would like to announce a new version of ldap-client-cgi.py, a WWW-LDAP-Gateway written in Python. It's available for free (GPL) from http://sites.inka.de/ms/python/ldap-client-cgi/ There's also a working demo there. I would like to encourage people to give feedback about the usability of this program. Ciao, Michael. Changes since 0.4.4 - complete re-design of add/modify - client-side schema checking with appropriate input forms for required and allowed attributes - automatically checking for missing parent DNs if add fails with "NO SUCH OBJECT" for reducing FAQ-traffic on OpenLDAP mailing lists ;-) - support for setting hashed passwords ({crypt},{md5} and {sha}) - minor enhancements of user interface - some small bug fixes <A HREF="http://sites.inka.de/ms/python/ldap-client-cgi/">ldap-client-cgi.py 0.5.0</A> - LDAP web client, now with support for client-side schema checking and hashed passwords.

Psion Series 5mx/7: Yet another Python port
by Otfried Cheong Sept. 26, 1999

Sept. 26, 1999

I've made a port of Python 1.5.2 to the Epoc operating system (as on the Psion Series 5mx, Series 7, NetBook, or Ericson MC218) available at http://www.cs.ust.hk/Python. This is a study in embedding Python in EPOC applications, and therefore has a quite different user interface from Duncan Booth's port. It behaves like a standard EPOC application, and you can run Python code by tapping it from the system screen.

Garbage Collection Patch for Python
by nascheme＠enme.ucalgary.ca Sept. 25, 1999

Sept. 25, 1999

Garbage Collection for Python This patch adds garbage collection to Python 1.5.2c1. Reference counting is still used. The garbage collector only frees memory that the reference counting does not (ie. reference cycles). This seems to provide the best performance. http://www.acs.ucalgary.ca/~nascheme/python/gc.html Currently the patch is only tested on Linux. It will probably work on other Unix machines as well. On my Linux machine, the GC version of Python passes all regession tests. Sample usage: $ cd Python-1.5.2c1 $ patch -p1 < ../gc-python-1.diff $ ./configure --with-gc The patch assumes you have libgc.a installed somewhere so that linking with -lgc works (/usr/local/lib should be okay). If you don't have the library, download and install it before compiling. If you are trying to fix a memory leaking Python program, Tim Peter's Cyclops module may also be useful. It is available on the Python ftp site.

Gnuplot.py v. 1.3
by Michael Haggerty Sept. 25, 1999

Sept. 25, 1999

This is to announce the release of version 1.3 of Gnuplot.py. Gnuplot.py is a Python [1] package that allows you to create graphs from within Python using the gnuplot [2] plotting program. This version fixes plotting of function objects and moves to a package structure. Gnuplot.py can be obtained from http://monsoon.harvard.edu/~mhagger/Gnuplot/Gnuplot.html Prerequisites (see footnotes): the Python interpreter [1] the Python Numeric module [3] the gnuplot program [2] Some ways this package can be used: 1. Interactive data processing: Use Python's excellent Numeric package to create and manipulate arrays of numbers, and use Gnuplot.py to visualize the results. 2. Web graphics: write CGI scripts in Python that use gnuplot to output plots in GIF format and return them to the client. 3. Glue for numerical applications (this is my favorite): wrap your C++/C/Fortran subroutines so that they are callable from Python, then you can perform numerical computations interactively from scripts or from the command line and use Gnuplot.py to plot the output on the fly. 4. Compute a series of datasets in Python and plot them one after the other using Gnuplot.py to produce a crude animation. Features added in version 1.3: * Converted to python package format. The main file is now called __init__.py, which can be loaded by typing 'import Gnuplot'. * Passing GridData a callable function was basically broken because of the kludgey way of overloading the argument. Instead of trying to fix it, I moved that functionality to a new type of PlotItem called 'GridFunc'. Features already present in older versions: + Two and three-dimensional plots. + Plot data from memory, from a file, or from an expression. + Support for multiple simultaneous gnuplot sessions. + Can pass arbitrary commands to the gnuplot program. + Object oriented, extensible design with several built-in types of plot items. + Portable and easy to install (nothing to compile except on Windows). + Support for MS Windows, using the `pgnuplot.exe' program. + Support for sending data to gnuplot as `inline' or `binary' data. These are optimizations that also remove the need for temporary files. Temporary files are also still supported. Footnotes: ---------- [1] Python <http://www.python.org> is an excellent object-oriented scripting/rapid development language that is also especially good at gluing programs together. [2] gnuplot <ftp://ftp.gnuplot.vt.edu/pub/gnuplot/> is a free, popular, very portable plotting program with a command-line interface. It can make 2-d and 3-d plots and can output to myriad printers and graphics terminals. [3] The Numeric Python extension <ftp://ftp-icf.llnl.gov/pub/python/README.html> is a Python module that adds fast and convenient array manipulations to the Python language.

GLADE/libglade: RAD GUI Building for GNOME/GTK+
by Markus Fleck Sept. 25, 1999

Sept. 25, 1999

HTML version: http://developer.gnome.org/news/summary/1999_September7-September21.html ============================================================== Lots of gushing about Glade -------------------------------------------------------------- Glade + libglade = REALLY EXCELLENT RAPID APPLICATION DEVELOPMENT TOOL! Check these out if you haven't. Glade is a nice GUI builder, it has lots of features and it's reasonably stable at version 0.5. Glade saves files in XML format; at runtime, your application can load them up using libglade. Basically this at least halves the number of lines of code involved for simple applications. It's very nice. We wrote a floppy formatter interface in 15 minutes just now. New Glade announced: http://www.gnome.org/mailing-lists/archives/gnome-announce-list/1999-Septem… New libglade announced: http://www.gnome.org/mailing-lists/archives/gnome-announce-list/1999-Septem… Note that the James Henstridge, the libglade author, is also the author of PyGNOME. He has Python bindings for libglade too. So you can combine Python with the GUI builder and create GNOME applications very, very quickly. ============================================================== FAQ: Frequently-Asked Questions at http://www.gnome.org/gnomefaq <A HREF="http://glade.pn.org">GLADE/libglade</A> - a GUI builder for GTK+ and GNOME that saves UI descriptions as XML files; also usable with PyGNOME.
