API to add a tree viewer / navigator to a web document ?

Folks,
  for one of you experts, this must be trivial / must exist already
within some big Python-web package:

say I'm looking at a long web doc.html which has no tree view on the
left,
but I can hack a local tree view file with level, name, href like

+ 1 US href=  ("+" button expands, "-" folds)
  2 Alabama href=
  3 ...
  2 Alaska href=
  ...
+ 1 Canada href=
  ...

Is there a small API that can generate a tree viewer / navigator from
this,
either side by side in the same browser window with the remote web
pages, or in a separate window ?
(The tree view lines can of course be reformatted to xml or whatever
the API wants.)

There are really 2 APIs here:
a) class TreeView
b) display the tree view and the remote web page in split windows.

(Is there a general introduction to Python-webbing
for someone who knows Python but almost no CSS nor web services ?)

Session events

Hi

I've been looking through the range of choices for Python web
[application] frameworks/libraries (Just to have all the bases
covered) for a new build project and standardisation of some small
utilities. There's one feature that I'm not finding and was just
wanting to check on before considering the joys of rolling my own: I'm
not finding any support for user session events, I'm particularly
interested in being able to register a handler on session expiry or
cleanup. I've mainly been looking at the lighter weight frameworks
since my requirement for the new build is mainly aggregate and list
operations, so the least suitable load for ORMs.

Have I missed the feature session event somewhere?

Thanks

I hope, for your own sanity, that by "rolling my own" you mean "my own
session extension", not "my own web framework." ;)

> Have I missed the feature session event somewhere?

You haven't missed it in CherryPy because we actually took it out a few
years ago on purpose--it was a request rare enough to warrant favoring
simplicity of the code base over feature creep. These days, the standard
approach in CP 3.x is to subclass cherrypy.lib.sessions.FileSession (or
one of the others), and add your own calls where you want them, then
just stuff your new class into the sessions module via
"cherrypy.lib.sessions.MyFileSession = MyFileSession" (and the config
system will automatically pick it up).

I would still recommend Django. I think it's the best web-framework if
you are beginning. It's not like PHP, but I don't know of anything like
PHP in Python.

Yes, it's hard, especially if you are new to web development.

Re: Web Framework

Hey, this is more complex than web2py:

 <at> bobo.query('/')
def hello():
     return "Hello world!"

In web2py you do not need the first line.

Hi Omar.  Please have a look at WHIFF.
It has a lot of PHP-like features, but it's better :).

Please let me know what you think of it.
I'd be especially interested if you find
the documentation hard to understand --
please let me know where you got confused or
whatever.  Thanks.

http://aaron.oirt.rutgers.edu/myapp/docs/W.intro

By the way I agree that PHP is ugly and most
Python frameworks are too complicated.  I also
think the only reason PHP is so popular is
because there was never an appropriate Python
based alternative for the kinds of things
people like to do with PHP.  This is the vacuum
I'm trying to fill with WHIFF.

This is supported at least here:

Re: API to add a tree viewer / navigator to a web document ?

WHIFF now has treeviews.

I will document the usage in a tutorial soonish.
In the mean time here are the test/demos

  reloading frame variant:
  http://aaron.oirt.rutgers.edu/myapp/root/misc/frameTest

  non-reloading ajax variant:
  http://aaron.oirt.rutgers.edu/myapp/root/misc/ajaxTest

The implementation supports large externally stored
trees.

Source for the implementations and demos
are available from the WHIFF mercurial archive

http://aaron.oirt.rutgers.edu/cgi-bin/whiffRepo.cgi

Hope you like!  -- Aaron Watters
