Hi,
I'm interested in using aspen as a configuration interface... where
aspen serves an HTML form, pre-populated based on the contents of a
configuration file. I would like the values to be adjustable by the
users who could then post the page back to aspen. Finally i would
like aspen to do some sanity checks on the data that was submitted and
write the data back to the config file.
Basically, I want to allow a user to modify the configuration file
of an application I'm working on using a web browser.
At first look, I think aspen can do it via its handlers. I wanted
to ask before I begin to invest significant amount of time
understanding python and aspen more as I'm not that good of a
programmer.

PS: this is related to a project for turning old laptops into picture
frames named "flickr-pitchr". The program is wrtten in python and
downloads images from flickr.com for display via SDL on a framebuffer
device.

Jason,
Yeah, should work. Do you have aspen installed? Try getting a
stdlib simplate running:
http://www.zetadev.com/software/aspen/0.8/doc/html/api-handlers-simplates.html
Simplates wiring example here:
http://www.zetadev.com/software/aspen/0.8/doc/html/handlers-conf.html
Then write your simplate like this:
"""
import os
CONF = os.path.join('path', 'to', 'file.conf')
^L
if environ['REQUEST_METHOD'] == 'POST': # <could be wrong API!>
blah = parse_form(environ)
fp = open(CONF)
fp.write(blah)
^L
<html>
<form action="<self>" method="POST">
...
</form>
</html>
"""
Check WebOb for environ wrapper:
hth,
chad
