And Now For Something Completely Different:
Zope Presentation Templates
-- by Ethan Fremen
"Zope Presentation Templates",
now in an alpha release, have the promise of both replacing
dtml and integrating well with wysiwyg tools, like Adobe
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:
There are "more examples",
including basic loop constructs.
After you download and try out the software, please give
some feedback to the "development project.",

Zope 2.3.1 beta 1 released
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 problems.
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

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 month.
You can read all about it at the "CMF dogbowl",
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
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.

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!).
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.
