And Now For Something Completely Different:


Zope Presentation Templates

— by Ethan Fremen

“Zope Presentation Templates”, http://www.zope.org/Members/tcoram/PresentationTemplates
now in an alpha release, have the promise of both replacing dtml
and integrating well with wysiwyg tools, like Adobe GoLive.

I’m really excited about this project: it should go a long way
towards us being able to have real separation of logic,
presentation, and data.

The basic idea is that attributes in a namespace will control
manipulation of nodes in a native XML namespace: the most common
example will be XHTML.

This means that you’ll no longer have a page so saturated with
additional tags that you cannot identify the underlying XHTML:
instead, you’ll have a well formed document that your editor can
play nicely with.

A crude example is:

<p tal_insert=”here/saying”>Dummy Text</p>

Assuming the document had a property called “saying”, with a
value of “Hello World”, the result would be:

<p>Hello World&l;t;/p>

There are “more examples”, http://dev.zope.org/Wikis/DevSite/Projects/ZPT/Examples
including basic loop constructs.

After you download and try out the software, please give some
feedback to the “development project.”, http://dev.zope.org/Wikis/DevSite/Projects/ZPT/CurrentStatus


Zope Status

Zope 2.3.1 beta 1 released

Recent News

This week’s not-so-weekly update: Thursday Feb. 15 we released
beta 1 of Zope 2.3.1. 2.3.1 will follow in a week or so barring any

The 2.3.1 release contains quite a number of bug fixes, both
issues found during the upgrade cycle to 2.3 and quite a few older
issues that had been languishing in the Collector. We anticipate
that 2.3.1 will be quite solid, so we will be able to turn some
attention to other things and start talking about some new
longer-term initiatives for Zope.


The Content Management Framework Formerly Known as the PTK

–by Ethan Fremen

The CMF has been on the fast track for the past month or so.
Tres reports that we should have a 1.0 release by the end of this

You can read all about it at the “CMF dogbowl”, http://cmf.zope.org so today I’ll just
hilight one of the exciting things in the CMF: Access-based
filtered searching.

An article that has just been written but not approved might
appear in a list of to-be-approved items for an editor. This list
is generated by a catalog query: however, a regular user, searching
for articles, will not see the yet-approved article.

Perhaps once this article is published, it is in a members only
area. Then, members will see it both in a catalog-driven list of
content, but also in raw searches, yet it will remain invisible to
the “Anonymous User”.

I reviewed quite a few indexing engines a while ago. Finding one
that stayed up-to date with the changes made to the site was hard
enough (All CMF content is automatically catalogued): Finding one
that gave a different set of results to different kinds of viewers
was impossible.


Zope Web

–by Ethan Fremen


For the past few weeks, Zope.org has been rather unstable. I’m
pretty confident in the zope software, and so I found this rather
unnerving. I put some work into tracking it down, but Shane
Hathaway really found the culprit, and Ken Manheimer finally put it
to rest.

The new wikis had an infinite-recursion loop that was causing
zope to segfault. Luckily, this has been corrected, and my pager
has been silent since (yay!).

Cluster Grows

Zope.org’s cluster is also getting a bit bigger: We’re adding a
new storage server so that the mail can have a machine to itself.
Other benifits of the new server will be support for files greater
than 2GB, so that zope.org will stop coming to a writing halt every
time the database passes that point.

We’re also adding another ZEO client box to the cluster that
will allow us to have a place to do things (like load in all of the
mailing list messages) that are a bit … resource intensive.

Zope.org grows up

Since the CMF is nearing release status, it’s high time that
Zope.org starts moving in that direction. We’re going to be
building a new Zope.org off of this one-dot-oh release, so stay
tuned for a lot of activity next month.
