[ANN] Pythonutils updates - approx, approxClientproxy, caseless etc
by Fuzzyman 10 Mar '05

10 Mar '05

Various of the Voidspace Pythonutils modules have been updated. http://www.voidspace.org.uk/python/index.shtml approx.py has been updated (Python CGI Proxy script) approxClientproxy.py version 2.0 is available listquote, caseless, linky, and downman have all been updated. *MAJOR UPDATE* approx.py approx.py is now at version 0.6.3 This includes many new features, improvements and bugfixes since the last public release 0.6.0. http://www.voidspace.org.uk/python/cgi.shtml#approx approx.py is a Python CGI proxy. It aids unrestricted internet browsing in a censored environment. It is inspired by the James Marshall Perl cgiproxy. Whilst it is not as fully developed as that script it has several advantages. These include URL obfuscation and that it is designed to work with approxClientproxy - see below. 2005/02/15 Version 0.6.3a Refactoring again - less global variables, slightly neater structure. (A full class based structure might still be better) Removed a couple of unimplemented features. Session cookies are now saved. (before they were always discarded) Userid can now be hardwired into approxClientproxy - meaning we don't get *hundreds* of cookie files. Updated default user agent. Fixed bug in cookie sending. (now can send the userid cookie on non-html pages and when modify is off) 2005/01/20 Version 0.6.2a Obfuscation changed to use dataenc. URL obfuscation now *only* available if dataenc and dateutils modules are available. (This restriction will be removed, and the functions built in, when testing is complete) 2005/01/02 Version 0.6.1c Fixed bug(s) in python 2.4 compatibility. Fixed bug in cookie naming. Removed extraneous whitespace from urls entered in the form. Fixed a bug in debug mode introduced in a previous update ! Logging is off by default - avoids file permission errors for new users. (If people want logging they can switch it on themselves) Removed a source of crashes in handling unsupported authentication methods. Basic url obfuscation implemented - for the sake of server logs. In the event of error we now keep the url in the form. Many thanks to Jose for testing and encouragement. *NEW* approxClientproxy.py Version 2.0.0 alpha February 2005 http://www.voidspace.org.uk/python/cgi.shtml#approx This is an experimental client proxy to go with approx.py. It runs on the client machine and transparently rewrites URL requests from the browser to go through the approx proxy. It doesn't yet support fetching https URLs, which is the target of the next update. *UPDATED* caseless and listquote updates http://www.voidspace.org.uk/python/modules.shtml#caseless http://www.voidspace.org.uk/python/modules.shtml#listquote These two modules have had updates for the latest ConfigObj update. This includes optimisations and improvements for unicode support. caseless provides a "Case Insensitive Dictionary, List and Sort" listquote "contains a set of functions for parsing lists from text and writing them back out again" *UPDATED* downman.py Version 0.3.1 17th February 2005 http://www.voidspace.org.uk/python/cgi.shtml#downman Simple download manager. A CGI script for 'serving' files for downlaod and gathering/presenting statistics about their use. Several minor improvements since 0.2, including support for different sections. 2005/02/17 Version 0.3.1 Added version string. Uses the 'formatbytes' function from pathutils. 2005/02/07 Version 0.3.0 Greatly simplified. Doesn't do links or use fileid. Will now serve files from several directories (sections) with different stats. Now can order results by average download rate (or reverse). Now displays file size and will sort by file size. Filenames are also links to the file. *UPDATED* linky.py Version 0.1.1 16th February 2005 http://www.voidspace.org.uk/python/programs.shtml#linky A script that uses BeautifulSoup to check links on a website. Particular emphasis is checking local links within a website and comparing link 'casing' with files on the filesystem. This will pick up errors when testing your website on windows (where case errors may not be apparent). Regards, Fuzzy http://www.voidspace.org.uk/python/index.shtml

cx_bsdiff 1.1
by Anthony Tuininga 09 Mar '05

09 Mar '05

What is cx_bsdiff? bsdiff is a very simple Python extension module that allows Python to perform the same tasks as the bsdiff utility available from http://www.daemonology.net/bsdiff and runs on any platform on which Python runs. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) This is the first release of this project. I have used it at our company for a couple of years now and found it quite useful. I have written a script that accepts a source and target directory and performs a diff between the two, storing the binary differences in a pickled file which can then be used to reconstitute the target directory given the source directory and the patch file. I am willing to make this available if there is enough interest. -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software. Real People.

[ANN] ConfigObj Update and New PythonUtils Package
by Fuzzyman 09 Mar '05

09 Mar '05

ConfigObj has had another update - now version 3.3.0 Several of the Voidspace PythonUtils modules have been packaged together as the 'Voidspace Pythonutils Package'. This makes it easier to release packages that depend on ConfigObj and the other modules. This update includes several important new features and bugfixes. New features include - string interpolation similar to ConfigParser, unicode support for reading and writing of config files, and a validation schema for validating config files. The validation schema is implemented using validate.py, which is co-written by Mark Andrews and maintained at http://www.la-la.com (although included in all the distributions). The unicode support will recognise and preserve the UTF-8 BOM when reading/writing files. Check out the docs for full details of the changes and how they work. Homepage : http://www.voidspace.org.uk/python/configobj.html For downloading, see the download section of the homepage. NEW ConfigObj API Docs Online : http://www.voidspace.org.uk/python/configob-api What is ConfigObj ================== A python module (class) for ultra simple reading and writing of simple config files, including config files with sections. Designed to allow the greatest flexibility in the config files it will read (and your users will create). Many flexible features - but you don't need to use them ! What's New ? ============= Changes in the new version : 2005/03/01 Version 3.3.0b Requires listquote 1.2.0 - which is improved/optimised Requires caseless 2.2.0 which has support for unicode Adding support for validation using the configspec To be done with an external validator. (Validator class created with help of Mark Andrews) This means added methods/attributes : parseconfigspec method stripconfigspec method validate method __configspec__ attribute BOM attribute Experimental unicode internally. 'encoding' and 'backup_encoding' keywords added 'lists' keyword added - can turn off list handling (lists are left as strings) A ConfigObj can be created by passing in a dictionary Added a __repr__ method for the ConfigObj configspec can now be a filename (or StringIO instance...) - including for the write method Now raises a TypeError rather than a KeyError if you pass in invalid options writein can now return a config file as a list of lines if no filename is set duplicate keys/sections in writein now raise 'duplicate' errors, rather than 'conspecerror' String interpolation from the 'default' section - using '%(keyword)s' format - similar to ConfigParser Attribute access as well as dictionary syntax Added a test for lists Coerce sections created as dictionaries to caselessDict (bug fix) Escaped '&mjf-lf;' and '&mjf-quot;' in unquoted values are converted (bug fix) Bug fixed in configspec with section files (bug fix) Bug fix in reporting of duplicate sections with configspec. (bug fix) Fixed bugs in sectionfiles with 'configspec_only' (errors in the empty last section would be missed) (bug fix) Bug fix in __buildconfigspec (bug fix) Improved support for '/*... */' in the writein method (bug fix) Fixed typo in verify and reset methods (bug fix) configspec is no longer destroyed for flatfiles (bug fix) Missing keys and Extra keys errors the wrong way round in write method (bug fix) Plus other minor bugfixes, simplifications and optimisations The next version will have some refactoring to use more reg-exes in parsing (I've had to succomb and import re for string interpolation so I might as well make better use of it) and improvements to the error system. *NEW* Voidspace PythonUtils Package Version 0.1.0 1st March 2005 http://www.voidspace.org.uk/python/pythonutils.html The Voidspace Pythonutils package is a simple way of installing the Voidspace collection of modules. For programs that use ConfigObj (which also requires caseless and listquote), it is simpler to install this package than to use the modules separately. This makes it simpler to distribute programs that depend on ConfigObj, without you having to distribute ConfigObj as well. Of course all the modules are useful in their own right. The modules included are : * ConfigObj - simple config file handling * caseless - case insensitive datatypes and sorting * listquote - list and element handling * validate - schema validation system * StandOut - flexible output object (simple logging and verbosity control) * pathutils - for working with paths and files * cgiutils - cgi helpers Regards, Fuzzyman http://www.voidspace.org.uk/python/index.shtml

Announcement: PyMatrix-0.0.1a Released
by Colin J. Williams 08 Mar '05

08 Mar '05

PyMatrix is a package to provide access to the functionality of matrix algebra. This package is currently based on numarray. It includes a statistics module which includes a basic analysis of variance. In the future it is hoped to enhance the generality of the divide operation, to add the transcendental functions as methods of the matrix class and to improve the documentation. The expectation is that Numeric3 will eventually replace numarray and that this will necessitate some changes to PyMatrix Downloads in the form of a Windows Installer (Inno) and a zip file are available at: http://www3.sympatico.ca/cjw/PyMatrix An /Introduction to PyMatrix/ is available: http://www3.sympatico.ca/cjw/PyMatrix/IntroToPyMatrix.pdf Information on the functions and methods of the matrix module is given at: http://www3.sympatico.ca/cjw/PyMatrix/Doc/matrix-summary.html Colin W.

ANN: PyEnchant 1.1.0
by Ryan Kelly 08 Mar '05

08 Mar '05

I'm pleased to announce the release of PyEnchant version 1.1.0. This release includes several major changes and additions of functionality: * Shiny new sourceforge site: http://pyenchant.sourceforge.net * Preliminary support for input/output with unicode objects as well as standard python strings * Windows installer now comes with MySpell as the default instead of ISpell, which generally gives better results. This backend is compatible with dictionaries from the OpenOffice.org project. ISpell support is also still present * The enchant.tokenize package provides functions for splitting text into its component words * The enchant.utils.SpellChecker class implements a high-level spellchecking loop over a chunk of text Unfortunately I dont have much experience with unicode so the preliminary support for it might be a little flaky. Anyone who can help with testing this out, would be very gratefully appreciated. Cheers, Ryan About: ------- Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ Current Version: 1.1.0 Licence: LGPL with exemptions, as per Enchant itself -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.
