Issues: 1. New Zope users often expect to be able to write  in order to get the effect of    2. In 1.10.13, at least, you can create an object with "/" in its id, with confusing and inconsistent results. Proposal: 1. Don't allow "/" in object ids. 2. Do allow tags with name arguments to treat  as equivalent to:      since it's so much more concise, and nicer than  (which I suspect of having slightly different semantics, as well). BTW, with this sort of thing should I just whip up a patch and send it to the Collector instead of testing the waters here? just-like-in-a-URL-ly y'rs Evan Simpson

Adding a ZClass via DTML
by Kevin Dangoor 14 Jul '99

14 Jul '99

A couple days back, there was a good exchange that showed how to create a ZClass instance via an External Method. Is there a convenient way to do this via DTML? It's really easy to add a Folder or a DTML Method through DTML... Kevin

ANN: Universal Zope Build System (looking for better name...)
by Anthony Pfrunder 14 Jul '99

14 Jul '99

Hi, Located at: http://student.uq.edu.au/~s341625/ Is a new version of what was 'Zope for Windows'. ZwinG2.zip contains a snapshot of a python make utility, makefiles etc for a cross-platform Zope build script. Current only works for Visual C ;), however, it should take only 15mins to finish off the platform specific bits (hint, hint). It works by abstracting the makefile and implementing *.exe, *.obj and *.pyd rules in loadable platform makefiles. For VC it drives it using the cmdline. I've included binaries for Zope A4 and it appears to work great - no patches required! Simply type: make install make zopec (or zopew for no console and update the icon ;) make ZExtensions and that's it! Exactly the same procedure for: * Mingw32 * Cygwin * Unix (not started yet though ;) Could those people using mingw32 fix up the cygwin.zmake. It compiles but bombs on a link. I've also got a plugin which I'll release when it is stable which generates a self-installing exe and / or a completely self-contained Zope server (ie run the exe and zope starts right away, no python, zope source needed!!). Naturally, equivalents are available on unix. Cheers, Anthony Pfrunder

maintaining a separate CVS branch
by Brian Hooper 14 Jul '99

14 Jul '99

Hi - I would like to be able to track the Zope sources but add my own changes on another branch, so that improvements to the main Zope sources would be easier for me to integrate in with my own site-specific changes - can anyone out there who knows how to do this with CVS give me some advice? The instructions for setting up CVS on the Zope site only show how to track the latest version of the sources, and this sets up everything as just a read-only mirror, as far as I understand. Is it possible to instead do a 'cvs import' of the Zope sources somehow and then make changes on another branch, in some way that would allow new sources and local changes to be automagically merged? I've read through the CVS docs but can't really figure this out. Thanks in advance, Zope on! --Brian

Patch: Add versatile "tag" method to Image
by bruce＠perens.com 14 Jul '99

14 Jul '99

The Image class has a str() method that outputs an <IMG ...> tag with an absolute URL, and with the height, width, and alternate text set for you. This is a very efficient way to embed images in your documents, because the page renders better when the height and width of the image are given and you don't have to hard-code them into your document, and the absolute URL uses the web browser's cache efficiently. However, I found this method constraining in that I could not add attributes such as "BORDER=0" to the tag. This patch adds a more versatile tag() method to Image. Arguments to the tag() method can be any of the usual IMG attributes. Defaults are provided for height and width (again, set from the image file) and For example:  ... will result in the image being rendered with the given attributes. Can we get something like this included in the main Zope thread?

possible problem in cPickleCache.c

My C compiler gives me a warning which on inspection I believe about an uninitialized variable usage at cPickleCache.c line 392. The code is static PyObject * cc_invalidate(ccobject *self, PyObject *args) { PyObject *inv, *key, *v; int i; if (PyArg_ParseTuple(args, "O!", &PyDict_Type, &inv)) { for (i=0; PyDict_Next(inv, &i, &key, &v); ) if (key==Py_None) { /* Eek some nitwit invalidated everything! */ for (i=0; PyDict_Next(self->data, &i, &key, &v); ) _invalidate(self, key); break; } else _invalidate(self, key); PyDict_Clear(inv); } else { PyErr_Clear(); UNLESS (PyArg_ParseTuple(args, "O", &inv)) return NULL; if (PyString_Check(inv)) _invalidate(self, key); /*possible error*/ else if (inv==Py_None) /* All */ for (i=0; PyDict_Next(self->data, &i, &key, &v); ) _invalidate(self, key); else { int l; -- Robin Becker
