It seems as if I am missing quite a bit of documentation. I have DTML, ZAG, ZCMG, ZDG (just the archive names) and tried to read about everything that is relevant to "plain" DTML (seems to be limited to DTML, ZCMG). But then I run into "Zope Quick Reference" which is quite massive and all very fine - the problem just is: where is the more elaborate counter-part to this *quick* reference, with all the explanations? Essentially I am looking for documentation on "techniques" - ways of how to do things. Now, there are quite a few of HOWTOs. But unfortunately most of these HOWTOs appear to demonstrate higher-level concepts. Take, for instance, <dtml-with Images> <dtml-in "objectValues(['Image'])"> <dtml-var sequence-item> </dtml-in> </dtml-with> which I found in the archives for this mailing list. Given the current "official" documentation, how could I have found out an explanation of what <dtml-in "objectValues(['Image'])"> does (ignoring the problem of how to find objectValues)? The only place I have found "objectValues" mentioned is "For example, to display all sub-objects of a folder, the objectValues method may be used (figure 13)." Sure, so what? What's this "Image" thing? Apparently it is an index into a Python list which returns a list of all images in the current folder? Name space? What else is there? Well, the "Entire Zope FAQ" (FAQ!) says "You can however, specify a list of object metatypes that it should return. objectValues(['DTML Document']) will only return all DTML Document objects in a Folder. Other metatypes you could select on are: Folder, DTML Method, File, Image, Mail Host, User Folder and Session." Do you see my problem? When I *have* something, I can *backtrack* this to at least some bits and pieces of information - although the only way to find it is a grep, which is as brute-force as it can be. But where is the documentation that "looks forward", that helps me to find out how to write "original" code? Reverse-engineering may be fun, but it's a bit time-consuming for my taste? Thanks for any pointers!
