another dtml-var question

Is it possible to sql_quote, then url_quote a variable, without copying the variable first. Something like <dtml-var name sql_quote url_quote>, which doesn't actually work. --sam -- -------------------------- Sam Gendler CTO, Impossible, Inc. 1222 State St. Suite 250 Santa Barbara, CA. 93101 p: 805-560-0508 f: 805-560-0608 c: 805-689-1191 e: sgendler(a)impossible.com

IMO you don't want a tag that translate strings based on word matching. The output won't be usable. (See my rantings in a previous email today). You might get nonsensical translations or partial translations. On the other hand I think "dtml-translate" is an interesting idea if translation is limited to full sentences or longer matches. >dtml-localize - this is a localized variable. normal acquisition does not work > with it. just the url transversal. and even the transversal is limited to > iso names. dtml-lvar looks for localized variables on the translator object > it has access to (default acquisition to find them) and inside folders > with iso names (as l10nfolder does at now.) We may need to look again at the ZI18N product and similar ideas. What do we need ? - A way to offer language choice based on browser settings. - The choice needs to be overridable (eg. first check cookies, then browser settings, then a property, then whatever.) - The language-choice services need to be available for existing products and objects. How about base classes (available for ZClasses too) that affect which object is returned from an URL (eg. return "index_html_FR" or "/FR/index_html" instead of index_html based on browser settings or acquisition path or a language property). Do we really need to add localization tags? Isn't there a way we can handle these issues at object level instead? Or did I miss the point? Cheers. Alexandre

WebDAV : Can not add webfolder to certain parts of zope
by Sin Hang Kin 24 Mar '00

24 Mar '00

I can add a webfolder on some brenches of my zope on the same pc under win98 and IE5. However, I can not add the root and some brenches. What is preventing this operation? I got the message when trying: Cannot connect to the Web server http://localost:8080 the server could not be located, or may be too busy to respond. Please check your typing or check to make sure the web server is available. I try to connect to serveral sub-folders under the root, some of them works, some not. However, I could not find the difference between them except the name. Rgs, Kent Sin

Perhaps, there's hope yet for a standard XML format for the Import/Export feature? See http://www.xml.com/pub/2000/03/22/psi/index.html. -Otto.

ZODB: interface for walking object graph?
by Andrew M. Kuchling 24 Mar '00

24 Mar '00

I'd like a way to find all instances of a given class in a ZODB. (In ODBMS jargon, this feature seems to be called "class extents".) The purpose is to handle changes to a class that require rearranging; you can do it lazily in a __setstate__ method, but after you've had 10 changes, that __setstate__ will be really complicated. And you can never simplify it, because you never know if there's a version 1 object hiding somewhere that just hasn't been accessed yet. Instead, I'd like to do it eagerly; write a script that loops over all the instances of class C, make a change to all of them, and then commit. I only see one way of doing this, by walking over the whole object graph starting from the ZODB's root objects. Storage objects do this in their pack() method to determine reachability. Problem: you'd have to copy the walking logic out of the pack() method into your own method. Proposal: expose some interface allowing clients of a Connection to run a function over every single object in a ZODB. It'd be like os.path.walk(), except over objects, not directories and files. This means unpickling *every* *single* object in the ZODB (and sending them all over the wire if you're using ZEO). Inefficient, but there seems no other alternative, and you wouldn't do this very often. Jim, what's your reaction? -- A.M. Kuchling http://starship.python.net/crew/amk/ Somehow the people who do as they please seem to get along just about as well as those who are always trying to please others. -- Bob Edwards

You could do this in a Version, perhaps -- that would lock the instances as they were changed, freezing out the "frequent writers," which isn't that bad an idea if you are changing their class, anyway; the other alternative would be to bring the HTTP server down and run the update in the Monitor. -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Translator 0.1 released
by al028823＠alumail.uji.es 24 Mar '00

24 Mar '00

Hi again! The dtml-str thread yesterday was very active and it continue.... :) Yesterday I printed the email messages and the L10NFolder source code and studied it before going to sleep. The result is the first release of the Translator product and this message, an attempt to join our until now dispersed work. Download the translator from http://www.zope.org/Members/jdavid/translator The translator product is just the old vocabulary product renamed following the Michell advices and with a new translate tag which is a first implementation of the Shane's proposal. Suppose the data contained by our Translator instance is: {'my': {'es': 'mi'}, 'house': {'es': 'casa'}, 'is': {'es': 'es'}, 'green': {'es: 'verde'} } Then if you type: "<dtml-translate>my house is green</dtm-in>" and "languages" is "['es']" then the result is "mi casa es verde" (and it's right!!). It does it by: - split the string - translate each word - join the string Yes, this is only a bogus algorithm but it shows how it would be. Future releases should allow to plug more intelligent translators. So now we have a good way to translate "static" strings: <dtml-var "translator('manage main')"> and also a good way to translate dynamic texts with the "dtml-translate" tag. Now I'm going to comment the L10NFolder by Federico. There're two things I don't like with it: 1. The L10NFolder changes the default behaviour of the dtml-var tag, this could break lot of dtml code in an unexpected way. The translator product does it in a different longest way. But other solutions could be tried, for instance the "dtml-var" tag could be modified to accept a new argument called "translate", if present it would translate the string returned by the "var" tag. For now I think the translator product approach is enough. 2. Say I have a University site which is an instance of my own product which subclasses Folder. Then I want to provide internationalization support using the L10NFolder, I have to modify my product so it subclasses from L10NFolder instead of Folder. I think it's not a good way. What I *really* like of the L10NFolder product is its url traversal special feature. I propose to implement that feature in the translator product but in a slight different way. Say my site is: University/ image Department/ image to transform it into a multilingual site I would add a translator object and translate the objects (documents, images,...): University/ translator image image_es Department/ document document_es Then the url "University/image" would return the "University/image" object but the url "University/translator/image" would return the "University/image_es" object. It could also be used deeper in the hierarchy so "University/Department/translator/document" would return "University/Department/translator/document_es". In this way there is no need to modify the python code, just modify the urls. What do you think about this Federico? If you think this is a better approach feel free to add your url traversal magic to the Translator product and your name to the copyright. There're also a lot of other issues I haven't talked about in this message because I think the first step is to join the work that has already been done in a single product. I think this translator thing can be a really powerfull feature, think about an Squishdot with multilingual support, each user sees the aricles and comments in their own language. Really a killing feature for Zope :) David
