[Zope] CMFCore.DirectoryView

[sean.upton@uniontrib.com]

Perhaps I misunderstand the issue, but a few months back Kapil repackaged
DirectoryViews for use outside the CMF...

They can be arbitrary but they can not be modified/defined "through the
Web".
You must change something in the file system.

You can have a general "__init__.py" that registers all directories
it finds by some means (e.g. via a configuration file).

Also, note, that with one directory all subdirectories can also be
accessed.

This, too, would be possible. But I do not know whether you should
go this way.

When you really want, you can search for a product that
provides for configurable startup scripts.
It allows you to put scripts in a special Zope folder that
are called automatically when Zope starts.
I forgot the name of this product...

It is usually "registerFileExtension" and not "registerMetaType".

Yes.

The same said for directories above applies for file extension.

Maybe.

"DirectoryView" has just been implemented for the CMF.
That we use it outside was probably not forseen...

Then you will need to wait until someone else modifies "DirectoryView"
to work somehow like "LocalFS".

It would probably be difficult but most people can probably
live with "DirectoryView" as it is now...
