[Zope-Annce] ZOQL Method 0.4.0 development preview
Fri, 11 Jan 2002 00:42:54 -0600
it has been a while, since the ZOQL team has posted any progress. This was
due to the fact that Thomas Foerster rewrote the entire ZOQL Grammar, Lexer
and Semantics! Everything is now much more object- and component-oriented
and therefore easier to develop with. The kwParsing Module (that generates
the language and provides the generic parser) has been adapted to Python
2.1 by moving all regex to re. There are also many unittests that help with
the quality assurance of the product.
The language rules itself changed slightly, in order to remove some sneaky
reduce and shift errors in the parser. We also changed some language rules,
if we found that the old way was inconsistent.
But I think the biggest new feature is the ability to add python-based
products (if your Zope user has the required permissions on the FS). Here
ZOQLMethod makes use of the slightly refactored MakeProduct product which
was originally developed by Erik Enge, Thingamy. Since Erik does not work
with Zope anymore, I took over the project, and will develop it further in
combination with ZOQLMethod.
Another small new feature is the ability to add sequences to your Zope
tree, but it does not do much yet.
What is ZOQL?
ZOQL is a query language similar to SQL for the ZODB. Since other Object
Query Language standards were not suitable, we developed ZOQL from scratch,
having only Zope in mind. ZOQL Methods allow you to quickly query and
manipulate objects in the ZODB. You do not require the ZCatalog or worry
about all the namespace issues.
There are no dependencies on ZOQLMethod and it should be platform independent.
