Zope Weekly News - Wed, 24 Nov 1999
by Mike Pelletier Nov. 26, 1999

Nov. 26, 1999

G'day, Zope Weekly News is a digest of some of the useful and interesting events which have occurred on the various Zope mailing lists and the Zope.org site. It is published each Wednesday evening. New Products and Announcements * "jwashin" released ZRTChat, an entirely ZClass real-time chat object. No java or javascript! http://www.zope.org/Members/jwashin/ZRTChat * The new Sybase Database Adapter has been released. It has been completely rewritten. http://www.zope.org/Products/DA/SybaseDA * "tseaver" submitted an internationalisation ZClass. It contains a set of translations of a document and serves the correct language to the user. http://www.zope.org/Members/tseaver/ZI18N * "Zen" has released GenericUserFolder, which seems to allow you to mix and match authentication methods to suit your needs. GenericUserFolder is very much beta, and not to be used on production sites. http://www.zope.org/Members/Zen/GenericUserFolder Updates * "anthony" released an update of his SQL Session product. SQL Session provides SQL database-based session objects, keyed to browser cookies. Unlike the previous update, this one does not break existing SQL Session objects. http://www.zope.org/Members/anthony/software/SQLSession * "rossl" has updated the LDAPAdapter product, which allows you to authenticate web users with an LDAP server. http://www.zope.org/Members/rossl/LDAPAdapter_0.7 * Itmar Shtull-Trauring has released v0.3 of ZCache. http://www.zope.org/Members/itamar/ZCache Zope.org items * "AlexR" posted a How-To about using ZCatalog's keyword index facility. A keyword index is something halfway between a text index and a field index-- it is a list of values which are treated atomically. http://www.zope.org/Members/AlexR/KeywordIndexes * Brian Lloyd has submitted a patch for Apache which allows you to use WebDAV with Zope through Apache. Normally Apache intercepts the HTTP OPTIONS request. With this patch, the request gets passed to Zope so it can offer WebDAV services. http://www.zope.org/Members/Brian/Misc/mod_cgi_webdav_patch.html * "Earthtone" wrote a mini-review of the Zope coverage in a new book, "The Quick Python Book". http://www.zope.org/Members/Earthtone/news-zope_chapter Notable Discussions * Sachin Shah wrote in to suggest that the Properties management view should include each of the property's type. Martijn Faassen agreed and suggested including the ability to change property types. Evan Simpson pulled a property-type-changer out of a hat! Oleg Broytmann suggests cut/copy/paste support. http://www.zope.org/pipermail/zope/1999-November/014379.html * "Chas" asked for advice selecting an OS for his Zope server. He will be using it with an Oracle server on another machine, and so the operating system must be supported by Oracle. Suggestions so far: Linux and Sun Sparc and FreeBSD with Linux emulation. No one has verified whether FreeBSD, Chas's preference, would actually work. http://www.zope.org/pipermail/zope/1999-November/014366.html * "Milt" wants to move a Zope server from a Windows machine to a Linux one. He solicited advice for accomplishing this. Solution: copy var/Data.fs from one machine to the other. It is platform-independent. http://www.zope.org/pipermail/zope/1999-November/014359.html * Ross Boylan gives us a heads-up on a bug in Zope Products. It seems that a failure in Product registration (ie, in the Product's __init__.py file) can cause Zope to misreport an old error, leading to the occasional headache. http://www.zope.org/pipermail/zope/1999-November/014340.html * Alexander Limi is understandably concerned about sending cleartext passwords over the Internet when authenticating Zope users and managers. Christopher Petrilli offers some solutions. http://www.zope.org/pipermail/zope/1999-November/014339.html * Jason Jone kicked off a brisk discussion of FastCGI and Zope. The verdict: to get full functionality, you have to use a snapshot (prerelease) of version 2.2.3 of mod_fastcgi. Using prerelease code made some people uncomfortable. This will change when 2.2.3-final is released. http://www.zope.org/pipermail/zope/1999-November/014254.html See also, doc/WEBSERVER.txt of the Zope CVS == Mike Pelletier. -- ----------- comp.lang.python.announce (moderated) ---------- Article Submission Address: python-announce(a)python.org Python Language Home Page: http://www.python.org/ Python Quick Help Index: http://www.python.org/Help.html ------------------------------------------------------------

o2x
by sabren＠manifestation.com Nov. 26, 1999

Nov. 26, 1999

Hey everyone, This is my contribution to pythondom.. :) XML can get ugly. There's a lot of editors for it that let you manage its tree-like structure, but I much prefer the simple outline-mode interface provided by emacs. So, I wrote o2x to convert outline-mode files to XML. (works as a module or standalone program) http://www.sabren.com/code/python/ Thanks, -Michal Sent via Deja.com http://www.deja.com/ Before you buy. <A HREF="http://www.sabren.com/code/python/">o2x</A> - convert Emacs ''outline mode'' files to XML.

Metalanguage (v0.3) for mxTextTools
by Tony J Ibbs (Tibs) Nov. 26, 1999

Nov. 26, 1999

This is to announce v0.3 (tiepin) of my metalanguage translator for mxTextTools. Marc-André Lemburg provides mxTextTools, a package of fast text manipulation tools for use with Python. The tagging engine within that package takes as input a set of tuples, the Tag Table, which tells it what to do. Although simple in format, these tuples aren't particularly readable, and indeed Marc-André himself says: "I admit, these tables don't look very elegant. In fact I would much rather write them in some meta language that gets compiled into these tables instead of handcoding them. But I've never had time to do much research into this, so unless someone volunteers, it will stay like this for some time." This version of the metalanguage translator implements enough notation to allow its own tag tables to be written in the metalanguage. Although it doesn't yet support various things (notably, strings with escaped quotation marks, function calls, and embedded tables with T/F conditions) it already provides enough power for most of my own needs, and should hopefully be useful to other people. Significant advantages of using the metalanguage are: * it avoids the problem of counting (and recounting) offsets between tuples * it avoids the pitfall of forgetting a comma between two tuples (which on my Windows machine at home is enough to crash Python) * it enforces indentation for meaning in the same way that Python itself does * it provides an "if" construct * obviously, I believe it to be more readable than the bare tuple notation Licensing: I like the Python Powered license at http://starship.python.net/~just/pythonpowered/ so please apply that with suitable amendments. Although Marc-André is aware of this work, it is in no way his fault (apart from the quote above and some helpful comments, for which thanks), so don't blame him... Note that mxTextTools v1.1.1 or later is required to use the translator. The metalanguage description and translator is available at http://www.tibsnjoan.demon.co.uk/mxtext/Metalang.html mxTextTools itself is available at http://starship.python.net/crew/lemburg/mxTextTools.html <A HREF="http://www.tibsnjoan.demon.co.uk/mxtext/Metalang.html">Metalanguage v0.3 for mxTextTools</A> - a little language (and its translator) to make it easier to write mxTextTools tag tables.

sockserv -- SMTP/NNTP/POP-like server module
by Sean Reifschneider Nov. 26, 1999

Nov. 26, 1999

The sockserv Python module allows one to easily create SMTP/NNTP/POP-like command/response socket servers very easily. Take the following example: import sockserv, os, string class uptimed(sockserv.sockserv): helpinfo_QUIT = ( '200- QUIT', 'Terminate the connection.' ) def do_QUIT(self, client, cmd, args): client.send('Bye now!', nl = 1) return(1) helpinfo_UPTIME = ( '200- UPTIME', 'Display hosts uptime information.' ) def do_UPTIME(self, client, cmd, args): uptime = string.strip(os.popen('uptime', 'r').readlines()[0]) client.send(str(uptime), nl = 1) s = uptimed(5000) s.mainloop() The standard socket library module is a fairly slim layer on top of standard Unix sockets. As you can see, this is a much higher-level abstraction. It's been in use internally for around a year now, and has been used as the base for numerous internal projects including SMTP servers and proxies, POP and other similar protocols.

TreeWidget 0.01
by Dieter Maurer Nov. 14, 1999

Nov. 14, 1999

TreeWidget 0.01 displays (dynamically changable) tree structures as interactive hierarchical content tables. (i.e. the display is similar to the left part of the MS Windows Explorer and other hierarchical tree browsers.) TreeWidget is based on Greg McFarlane's excellent Python MegaWidget Framework (URL:http://www.dscpl.com.au/pmw/). It is similar to the TreeExplorer in Doug Hellmann's PmwContribD package (URL:http://members.home.net/doughellmann/PmwContribD/index.html), but supports dynamic modification of the displayed tree. More information and download at: URL:http://www.handshake.de/~dieter/pyprojects/treewidget.html - Dieter <A HREF="http://www.handshake.de/~dieter/pyprojects/treewidget.html">TreeWidget 0.01</A> - displays PMW-based hierarchical content trees; similar to TreeExplorer from the PmwContribD package.

Hello, I'm pleased to announce the second release of GPS - Groves and Property Sets for Python. There has been a lot of changes in this release. The most important being the support for grove managers and managed grove nodes, and a grove walker module. See the changes.txt file in the distribution for a complete list of changes. Suggestions and bug reports should be sent to: grove(a)infotek.no Geir O. Grønmo -------------------------------------------------------------------------- Title: GPS - Groves and Property Sets for Python Version: 0.20 Released: November 12th 1999 Author: Geir O. Grønmo, grove(a)infotek.no License: GPL Homepage: http://www.infotek.no/~grove/software/gps/index.html - -- >>> What is GPS? GPS is an implementation of the groves and property set concepts defined in the HyTime and DSSSL standards. GPS is written in Python, and should work* on any platform to which Python have been ported - including the Java Platform. There are two implementations in the current distribution, one in-memory implemention and one that supports ZODB - the Zope Object Database. Both groves, property sets and grove plans can be made persistent by the ZODB implementation. - -- >>> Features o Loading of property sets from documents conforming to the Property Set DTD, or any derived DTD [requires architectural processing]. o Grove plans. Default grove plans is automatically created by wrapping a GrovePlan object around a property set. Inclusion and omitting of modules, classes and properties are fully supported. o Self-managed and managed grove node implementations, both generic classes for representing grove nodes. o Grove managers that manages a repository of managed grove nodes. o ZODB - Zope Object Database versions of all grove, grove manager, property set and grove plan classes, plus some ZODB utilities. o Module for building XML groves from SAX event streams. This module also contains a class for emitting SAX events by walking XML groves. o Grove walkers, allows for selective processing of groves. o Sample Property Sets - -- >>> Requirements - Python 1.5.2 or newer [3] - An SGML/XML parser with a SAX driver - SAX 1.0 for Python [4] - xmlarch 0.25, optional unless architectural processing is needed [5] - -- >>> References [1] http://www.jpython.org/ [2] http://www.ornl.gov/sgml/SC34/ [3] http://www.python.org/ [4] http://www.stud.ifi.uio.no/~larsga/download/python/xml/saxlib.html [5] http://www.infotek.no/~grove/software/xmlarch/index.html [6] http://www.infotek.no/~grove/software/gps/licence.html * The ZODB implementation won't work in a Java environment, since ZODB contains code written in C. -------------------------------------------------------------------------- <A HREF="http://www.infotek.no/~grove/software/gps/">GPS 0.20</A> - Groves and Property Sets for Python; an implementation of the groves and property set concepts defined in the HyTime and DSSSL standards.
