[ANNOUNCE] gmpy 1.0 alpha released
by Alex Martelli 13 নভেম্বর, 2005

13 নভেম্বর, 2005

See http://gmpy.sourceforge.net/ for details. What is it: a wrapper for the GMP library, to provide multi-precision arithmetic for Python. Multi-precision floats, and unbounded-precision rationals, are not present in stock Python; multi-precision integers ('long') are, but gmpy's version of multi-precision integers is faster for some operations (NOT all -- used to be, but Python 2.3 did serious enhancements to some operations on longs) and provides lots of nifty pre-packaged additional functions. Minor changes and bug-fixes since the latest 0.9 pre-alpha; support for Python 2.3. The Windows binary release is now for Python 2.3 _only_ (if you're stuck with Python 2.2 on Windows, you can keep using gmpy 0.9 pre-alpha and not really suffer from that). Known bug on Windows: the scan0 and scan1 functions appear broken (perhaps related to the lack of a GMP 4.0 library for Windows -- haven't found one around yet). Alex

ANNOUNCE: KirbyBase 1.7.1 (Bugfix Release)
by Jamey Cribbs 31 জানুয়ারি, 2005

31 জানুয়ারি, 2005

After releasing version 1.7 yesterday, I found a bug this afternoon that could result in incorrect query results if you are doing a regular expression query against more than one string field. So, I felt like I needed to get a quick bug-fix version out the door to try to minimize the damage. You can download KirbyBase for Python at: http://www.netpromi.com/files/KirbyBase_Python_1.7.1.zip You can find more information on KirbyBase at: http://www.netpromi.com/kirbybase.html Sorry about this! I hope the bug did not negatively impact anyone. Jamey Cribbs

ANNOUNCE: Rx4RDF and Rhizome 0.4.3
by Adam Souzis 31 জানুয়ারি, 2005

31 জানুয়ারি, 2005

Rx4RDF is application stack for building RDF-based applications and web sites implemented in Python. Rhizome is a Wiki-like content management and delivery system built on Rx4RDF that brings the Wiki metaphor to building dynamic web sites. What's new? Major changes since last announced release (0.4.1): - Support for RDF Schema (subclasses and subproperties) - Added a UI for adding comments and several other UI improvements - Added a notion of themes to ease customization of look and feel. - More security enhancements including sanitizing HTML and supporting Google's new anti-comment spam standard. - Smoother installation and command line handling. - Compatibility with 4Suite 1.0a4 (enables OS X support). In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details. More Info: * Rx4RDF is a set of technologies designed to make RDF more accessible and easier to use. It includes: ** RxPath provides a deterministic mapping between the RDF abstract syntax to the XPath data model, allowing you to query, transform and update a RDF model with languages syntactically indentical to XPath, XSLT and XUpdate (dubbed RxPath, RxSLT, and RxUpdate respectively). ** ZML is a Wiki-like text formatting language that lets you write arbitrary XML or HTML (using Python-esque indentation rules), enabling you to author XML documents with (nearly) the same ease as a Wiki entry. ** RxML is an alternative XML serialization for RDF that is designed for easy authoring in ZML, allowing novices to author and edit RDF metadata. * Raccoon is a simple application server that uses an RDF model for its data store, roughly analogous to RDF as Apache Cocoon is to XML. Raccoon uses RxPath to translate arbitrary requests (currently HTTP, XML-RPC and command line arguments) to RDF resources, each of which can be associated with RxSLT and RxUpdate stylesheets. * Rhizome is a Wiki-like content management and delivery system built on Raccoon that takes the concept of the Wiki to the next level: everything is editable, not just content but its meta-data and behavior, even the structure of the site itself. Furthermore, Wiki entries are abstract globally unique RDF resources that can have any kind of content and whose presentation is contextual.

ANNOUNCE: VendorID-1.0.0
by Ulrich Berning 31 জানুয়ারি, 2005

31 জানুয়ারি, 2005

I'm pleased to announce the first public release of VendorID-1.0.0. You can download it from www.riverbankcomputing.co.uk/vendorid ----- What is it? VendorID is a Python package, that contains functionality to restrict the availability of dynamic loadable extension modules to specific Python interpreters. Only specific Python interpreters are allowed to import such extension modules. A generic Python interpreter will fail to import such extensions. By the term specific Python interpreter, we mean a binary executable that runs a single specific Python application, something you create with tools like freeze or py2exe. ----- Why? The motivation for the VendorID package was the following condition in Trolltech's commercial Qt license agreement. "Applications may not pass on functionality which in any way makes it possible for others to create software with the Licensed Software;" This software provides a simple mechanism for conforming to this condition. Because I want to create commercial applications based on Python, Qt and PyQt, I either had to make the PyQt modules builtin into the specific interpreter (resulting in huge executables), or I had to find a solution to prevent the import of these modules from a generic Python interpreter. ----- Contents of the Package The VendorID package contains a distutils setup script that generates the necessary code and builds a static library and a shared module. The package also contains a Python script named sib.py that you can use to create application specific executables. See the documentation in the doc directory of the package. ----- License VendorID is licensed under the same terms and conditions as Python itself. See the file LICENSE.txt of the package for more details. VendorID places no restrictions on the license you may apply to interpreters and extension modules that make use of the VendorID functionality. ----- If you have any questions or enhancement suggestions, either contact me directly (ulrich.berning(a)desys.de) or use the PyKDE mailing list. Thanks to Phil Thompson for hosting the package at www.riverbankcomputing.co.uk Ulli Berning DESYS GmbH www.desys.de

[ANN] PyComicsViewer 0.9.5
by ionutz 31 জানুয়ারি, 2005

31 জানুয়ারি, 2005

PyComicsViewer-0.9.5 has been released. What is PyComicsViewer? ======================= Is a comics viewer written in python, PyGTK and PIL. I made it as I didn't fully like any of the existing viewers and I wanted something that works the same (nice) way on both Linux and Windows. Because of the way it was implemented, you can also use it like a kind of image browser/viewer, but this is not its primary destination. Browsing images from uncompressed directories is provided because resulted naturally from the implementation and because I've seen some people that distribute their scaned comics uncompressed. Changes in 0.9.5 (2005/01/30) ============================= * solved rotation bug for images that have sizes not divizible by 4 * set the size of the 'Open' dialog in the glade template, not in the program * show the number of files detected so far during dir scanning * set UI to use tear-off menus * added code to sort files alfa-numerically (that is, the file '5.jpg' will come before '10.jpg') * better installation support Licensing ========= PyComicsViewer is released under the GPL. Where can I get it? =================== Home page: http://borco.net/html/PyComicsViewer/ Latest version: http://borco.net/html/PyComicsViewer/PyComicsViewer-0.9.5.tar.gz Cheers,

cfgparse v01_00 released
by Dan Gass 31 জানুয়ারি, 2005

31 জানুয়ারি, 2005

I'm pleased to announce the initial release of cfgparse (V01_00) Background ------------------------------------------------------------- cfgparse is a more convenient, flexible, and powerful module for parsing configuration files than the standard library ConfigParser module. cfgparse uses a more declarative style modelled after the popular optparse standard library module. cfgparse can optionally cooperate with the optparse module to provide coordination between command line and configuration file options. In addition, the cooperation can be used to allow the user to control features of the parser from the command line. URLs ------------------------------------------------------------- Docs/home page: http://cfgparse.sourceforge.net/ Download: http://sourceforge.net/projects/cfgparse/ Feature Summary ------------------------------------------------------------- + Simple ini style configuration syntax + Type checking with error handling and help messages + Help summary modelled after that in optparse + Round trip - read, modify, write configuration files with comment retention + Cooperates with optparse for configuration file options that should be overridden by command line options + Supports heirarchically organized option settings * User may store multiple option settings in a arbitrarily deep keyed dictionary. * Application uses a key list to walk into the dictionary to obtain a setting. * User controls key list with setting in configuration file. * Supports adding keys to the list through a command line option or from environment variables. + Supports allowing user control of configuration files used. * Environment variables may be used to allow user to specify a default configuration file. * Command line options to specify configuration file supported. * Configuration files may include other configuration files where where sections are read in parallel. * Configuration files may be nested heirarchically by including configuration files from within a section or subsection. + Configuration files may alternatively be written in Python. * full power and flexibility of Python available for creation of option settings * allows options settings to be real Python objects * this feature is NOT enabled by default + May be extended to support syntax such as XML. Enjoy, Dan Gass

ANNOUNCE: KirbyBase 1.7
by Jamey Cribbs 30 জানুয়ারি, 2005

30 জানুয়ারি, 2005

KirbyBase is a simple, plain-text, database management system written in Python. It can be used either embedded in a python script or in a client/server, multi-user mode. You use python code to express your queries instead of having to use another language such as SQL. KirbyBase is disk-based, not memory-based. Database changes are immediately written to disk. You can find more information on KirbyBase at: http://www.netpromi.com/kirbybase.html You can download KirbyBase for Python at: http://www.netpromi.com/files/KirbyBase_Python_1.7.zip Wow! It's been almost two years since the initial release of KirbyBase. Time sure does fly! Version 1.7 includes most of the bug fixes that have accumulated over the months and a few enhancements that I hope you will enjoy. I would like to thank everyone who has emailed me with comments, bug reports, and enhancement requests/ideas. Hearing from people who actually use KirbyBase is what makes working on it worthwhile. Please keep the emails coming! I would particularly like to thank Pierre Quentel, the author of Karrigell (http://karrigell.sourceforge.net), for his contribution of ideas and code for many of the enhancements in version 1.7 of KirbyBase. For those of you who requested better documentation, the manual has been completely re-written. I'm not saying it's any better, but at least it's different. :) Changes in Version 1.7: ***IMPORTANT - IF YOU ARE UPGRADING THIS COULD BITE YOU!!!*** * Changed the default value for the keyword argument 'useRegExp' to be false instead of true. This means that, when doing a update, delete, or select, records being selected on string fields will be matched using exact matching instead of regular expression matching. If you want to do regular expression matching, pass 'useRegExp = True' to the method. ***IMPORTANT*** * Added a keyword argument to select() called returnType. If set to 'object', the result list returned will contain Record objects where each field name is an attribute of the object, so you could refer to a record's field as plane.speed instead of plane[4]. If set to 'dict', the result list returned will contain dictionaries where each key is a field name and each value is a field value. If set to 'list', the default, the result is a list of lists. * Added a new method, insertBatch. It allows you to insert multiple records at one time into a table. This greatly improves the speed of batch inserts. * Added a new public method called validate. Calling this method with a table name will check each record of that table and validate that all of the fields have values of the correct type. This can be used to validate data you have put into the table by means other than through KirbyBase, perhaps by opening the table in a text editor and typing in information. * Fixed a bug in _closeTable where if an exception occurred it was blowing up because the variable 'name' did not exist. * Fixed a bug in _writeRecord where if an exception occured it was blowing up because the variable 'name' did not exist. * Fixed a bug in _getMatches where I was referencing self.field_names as a method instead of as a dictionary. * Added a new private method, _strToBool, that converts string values like 'True' to boolean values. * Added a new private method, _convertInput, and moved to it the code that ensures that the data on an insert is in proper list format. I did this so that I did not have duplicate code in both the insert and insertBatch methods. * To accomodate the fact that users can now send a large batch of records to be inserted, I changed _sendSocket so that it first sends the length of the database command to the server, then it actually sends the command itself, which can now be any length. * Changed the code in _getMatches to precompile the regular expression pattern instead of dynamically compiling every time the pattern is compared to a table record. This should speed up queries a little bit. * Changed the code in select that converts table fields back to their native types to be more efficient. * Changed _sendSocket to use StringIO (actually cStringIO) to hold the result set of a client/server-based query instead of just capturing the result by concatenating records to one big string. In informal testing on large result sets, it shaves a few tenths of a second off the query time. Jamey Cribbs jcribbs(a)twmi.rr.com

ANN: ClientForm 0.1.17
by jjl＠pobox.com 30 জানুয়ারি, 2005

30 জানুয়ারি, 2005

http://wwwsearch.sourceforge.net/ClientForm/ The old 0.0.x series is no longer supported. This is a bugfix release. Changes from 0.1.16 to 0.1.17: * Fix case where FORM action contains a '?' or '#' (again!). * Fix failure to raise ParseError (!) * Workaround for failure of sgmllib to unescape attributes (bug report from Titus Brown). * Fix image control in case where value is present. * Hack choose_boundary not to fail on hostname lookup. * Allow user to supply own Request class. * Fix ISINDEX action URL (bug only showed up in Python 2.4). Requires Python >= 1.5.2. Works with Python 2.4. ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. It has developed from a port of Gisle Aas' Perl module HTML::Form, from the libwww-perl library, but the interface is not the same. Simple example: from urllib2 import urlopen from ClientForm import ParseResponse forms = ParseResponse(urlopen("http://www.example.com/form.html")) form = forms[0] print form form["author"] = "Gisle Aas" # form.click returns a urllib2.Request object # (see HTMLForm.click_request_data.__doc__ if you're not using urllib2) response = urlopen(form.click("Thanks")) John

ANN: F2PY - Fortran to Python Interface Generator
by Pearu Peterson 30 জানুয়ারি, 2005

30 জানুয়ারি, 2005

F2PY - Fortran to Python Interface Generator -------------------------------------------- I am pleased to announce the ninth public release of F2PY, version 2.45.241_1926. The purpose of the F2PY project is to provide the connection between Python and Fortran programming languages. For more information, see http://cens.ioc.ee/projects/f2py2e/ Download: http://cens.ioc.ee/projects/f2py2e/2.x/F2PY-2-latest.tar.gz http://cens.ioc.ee/projects/f2py2e/2.x/F2PY-2-latest.win32.exe http://cens.ioc.ee/projects/f2py2e/2.x/scipy_distutils-latest.tar.gz http://cens.ioc.ee/projects/f2py2e/2.x/scipy_distutils-latest.win32.exe What's new? ------------ * Added support for wrapping signed integers and processing .pyf.src template files. * F2PY fortran objects have _cpointer attribute holding a C pointer to a wrapped function or a variable. When using _cpointer as a callback argument, the overhead of Python C/API is avoided giving for using callback arguments the same performance as calling Fortran or C function from Fortran or C, at the same time retaining the flexibility of Python. * Callback arguments can be built-in functions, fortran objects, and CObjects (hold by _cpointer attribute, for instance). * New attribute: ``intent(aux)`` to save parameter values. * New command line switches: --help-link and --link-<resource> * Numerous bugs are fixed. Support for ``usercode`` statement has been improved. * Documentation updates. Enjoy, Pearu Peterson --------------- <P><A HREF="http://cens.ioc.ee/projects/f2py2e/">F2PY 2.45.241_1926</A> - The Fortran to Python Interface Generator (30-Jan-05)
