[Ann] DocFinder 1.0: ask Zope about its documentation
by Dieter Maurer 25 Aug '03

25 Aug '03

It is often difficult to find accurate documentation about the Zope infrastructure. Often, I have written: look into the Zope source, its source documentation is quite good. However, as Zope's implementation language Python provides good introspection facilities, there is a better way: extract the documentation directly from Zope. That's what 'DocFinder' does. It analyses any Zope object inside a running Zope, determines which classes have been used in the object's makeup and provides information about their class level attributes: name, allowed roles, arguments, documentation strings. It provides (read only) access to to source code of Python implemented classes and methods, as well. What's new in version 1.0: * Direct access to source code of Python implemented classes and methods * Implemented as a single persistent <code>DocFinder</code> instance (rather than a DTML object and External Method pair) * Alternative URL-calling to document objects which intercept traversal * Now uses PageTemplates rather than DTML for presentation More information and download: <http://www.dieter.handshake.de/pyprojects/zope/DocFinder.html> Dieter

@python.org and @zope.org email troubles
by Martijn Pieters 22 Aug '03

22 Aug '03

Thanks to the enormously proliferant W32.Sobig.F, the mail.python.org email server has been having real trouble dealing with the flood of email pounding on it's ports. We are currently hard at work trying to bring the mailserver back to sanity again, and you should be seeing email emerge again, although it may take some time still before things will be back to normal operation. In the meantime, we apologize for the inconvenience. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

VarImage 2.3 Released
by Terry Hancock 20 Aug '03

20 Aug '03

VarImage means "Variable Image" -- it is a Zope product which allows you to load a single image and serve modified versions of it, but with efficient caching. Thus you can have most of the flexibility of "on-the-fly" image generation, with very little penalty compared to pre-prepared images. Available from: http://www.anansispaceworks.com/papers_html#VarImage-2.3.tgz Provided plugins allow for: scaling, resizing, cropping, foveal thumbnailing, photonegative, black-and-white conversion, color tinting, superimposition of "image components" to construct composite images, and simple drop-shadow effects. Although VarImage itself does not explicitly rely on Python Imaging Library, all of the currently distributed plugin operators do. VarImage supports a simple plugin API for writing your own image operators. New in 2.3: Interactive graphical ZMI tool for setting the image fovea. (Requires manager to use a javascript/CSS capable browser -- tested working on Mozilla 1.0.0, Konqueror 2.2.2, probably works on IE 5+ (untested), doesn't work on Netscape 4.77). "Key" syntax for calling from Python expressions or code, e.g.: <dtml-var expr="my_image_png['tn_100_100.jpg']"> Streamlined regeneration code, and fixed several bugs affecting large or unusual images. Foveal thumbnailing algorithm fixed for some edge cases that failed to preserve correct aspect ratios. There is also a "drop shadow" plugin, contributed by Andrew Meier, and a "no-op" plugin for testing images for PIL compatibility. Improved the failover behavior for errors occuring in the plug-ins (usually in PIL): in most cases, a "VarImage Error" will be served if the conversion fails. Enjoy!

Ape 0.7.1 Released
by Shane Hathaway 18 Aug '03

18 Aug '03

Ape 0.7.1 has been released. Version 0.7 had not been adequately tested with Python 2.1, but this release fixes the bugs discovered by Seb Bacon and others. http://hathaway.freezope.org/Software/Ape BTW, here is another reason you might want to try Ape: Ape transparently converts a static HTML site into a dynamic site using page templates. Just add static HTML on the filesystem, then add TAL attributes to the .html files either through the web or on the filesystem. Try it! Shane

Ape 0.7 Released
by Shane Hathaway 11 Aug '03

11 Aug '03

Ape version 0.7 is ready. There's something new for everyone: Ape now uses XML to configure mappers, gives other products an opportunity to enhance the mappers, periodically scans the filesystem for changes to cached objects, and if you like to ride the wild side, there's experimental code for storing properties using one table per class. Ape (short for Adaptable Persistence) adapts Zope objects to storage on the filesystem, in relational databases, or practically anywhere else. It combines the advantages of transparent object persistence with arbitrary databases and formats. It is especially designed to work with ZODB, but can work independently of both Zope and ZODB. Give it a spin. This is still an alpha release because there are some unstable APIs, but with help a beta could come soon. http://hathaway.freezope.org/Software/Ape Shane
