This would be a pretty hard part of your dream to realize, someone would have to think very hard about it and be very, very good with both python and Java. Remember, alot of the trickiest parts of Zope are written in C, and almost all objects dabble their hands in Acquisition, which is written in While were on the subject, I have a dream too, people not sending HTML encoded mail to the list. ;) -Michel

I have a dream!

The Zope creator: Being around for almost a year, I still not able to handle its syntax. I recently notice zope have several xml products. I have a dream to able to draw my web site with a WYSIWYG editor and save it as XML, then, Zope convert it into a zope tree. This ever have advantage for normal document, which, for example, if i need to cross-reference a part, I could just specify an id for that part, and insert it with dtml syntax. This combine with WEBDAV with so turning zope an ideal document management server. We would see that it point to very promising and creative use of zope. If zope is fast and stable enough, it can even play as an object file system. I would like to re-arrange the recent zope (dtml) syntax to allow the use of dot (.) as object name ; a syntax like that xsl using to reference to objects in the zope tree; and a unified the naming of zope-defined variables and methods. I would also like zope to handle true xml with full unicode support, changing zope syntax (dtml) to compily with xml so it can be processed by zope and other xml tools. I hope I am not asking for too much, but I can't hold to spell out my dream. The last wish is zope be compatible with both cpython and jpython. Rgs, Kent Sin

Yep, yer right there. and I suspect there might be a future need for a generalization, say, PATH that truely is protocol independent. I think Jim is thinking really hard about this right now for particular problem he has, 'upwards' and 'downwards' references between objects. > That way, I could > just say <a href="ftp://&dtml-url0">download this page</a> > and everything would be hunky-dory, _assuming_ I'm not > worried about multi-hosting. Perhaps it could be abstracted out more than that. I dunno. Maybe we could let ZPublisher build up URLs that accuratly reflect the protocol used during the request. I don't know if this is a good idea or not either, but maybe I've been afraid to suggest some sort of application level variable that defines the current request's protocol. We allready have quite a few that define HTTP specific stuff... I didn't intend my message to say that protocols shouldn't be taken into account in the application but I guess that's what I said. If they are taken into account, there should be a pretty well thought out way they are presented to the application level logic (and at some degree maybe even the DTML level). -Michel > > On the subject of multi-hosting, shouldn't a FTP0 be > intelligent enough to go where the file is actually hosted? But FTP is a different medusa module than HTTP. They would both need to be configured to work with multi-hosting. I think that the plan is, down the road, we *might* put virtualhost support in ZServer's http server (or, we could just leave that whole death pit for the apache folks). I'm not sure if multi-hosting FTP is planned at the same time, it does introduce a mighty interesting problem of configuration, we might have to bring ourselve to have some sort of XML based configuration *file*, which is something we've avoided completely, having stuck with the command-line argument style of doing things. However, there is a plus to a config file, if it's XML and parsable then Zope itself (as an application) could be used to configure it's protocol level components through a yet to be defined API. > > But doesn't BASE/URL violate what you're saying? or do I > misunderstand how they work?

In your method you can string.split(URL0, SCRIPT_NAME) and you'll get just the path of the requested object. I've found that useful. -Michel

Zope direction and 2.2 roadmap...
by Brian Lloyd 08 Dec '99

08 Dec '99

Hi all. Now that Zope 2.1.0 is out the door, we at DC want to let the community know our direction and the "roadmap" leading to 2.2. In a nutshell, our direction and focus will be on usability. Making it easier to get things done with Zope has been a recurring theme on the lists lately, and we will be working to make progress on this front. For 2.2, here is the short list of we will be working on: o Online Help System - Amos has been doing great work on a real honest-to-goodness online help system for Zope that will make its debut in 2.2. o Python Methods - work will be done to include Evan Simpson's Python Methods in the Zope core. This should help a lot in avoiding the headaches of convoluted DTML logic. o Site Objects - will make it easier to deploy "virtual sites" in the same Zope with far less effort than is required now. o The ability to associate ZClasses as "brains" for relational database data instead of having to write Python classes. o And of course, fixes for bugs and issues in the Collector. We are expecting to have these things available in at least a pre-release by the time of the Zope track at the Python Conference. There are other usability initiatives underway as well. Rob and Amos have been doing a _lot_ of work coming up with a much better and much more scalable approach to documentation that should have a big impact on the quality and breadth of documentation. Work will also continue on making Zope.org a better resource with things like ZTopics (Yahoo-style directory views). And there are some other projects percolating (which I can't talk about yet :) that will have a big impact on usability.

What happens though when the HTTP side of Zope supports multi-hosting (as it will in 2.2) and the FTP side doesn't? When you start putting protocol specific widgets at the application layer (which is supposed to protocol independant) expect to be bitten somewhere, at some time. I would love to be able to, for example, detect when a method is being called by XML-RPC instead of HTTP, but it just can't be done, and it *shouldn't* be done, because all information pertaining to the protocol should be abstracted out at the application. -Michel

request: FTP

The BASE and URL are great. I'd love, however, to be able to say FTP0 and get the same behavior as BASE0 or URL0 (take yer pick) but with ftp:// on the front instead of http:// could someone point to where I could hack this? -- Ethan "mindlace" Fremen you cannot abdicate responsibility for your ideology.

Hi. If you know the decision of a problem of search char, if char > 127, please explain, how to decide this problem. I use locale, but "Russian" not always works correctly. Sergey.
