Hi --
I really hope that one day the world will forget about CGIs and never look back.
This is probably my own opinion, although I'm relatively sure that others feel
the same way. There are many better technologies for web based applications,
I've listed many of them before. One of the best (but alas, poorly documented
and hard to learn) is Woven from Twistedmatrix.com . Using a python web
application framework would "only require python", if you did just a little bit
of hacking you could bring just the parts of Twisted needed for Woven (or some
other python web framework).
You seem to have good knowledge of Python, but have you looked into other Python
web technologies other than the tried and true but antiquated and limited CGI?
One thing woven will allow you to have is have complete separation of code and
display (MVC again).
Code sections such as:
def page_header(title):
print "Content-Type: text/html"
print
print
print '<html><head>'
print '<title>',title,'</title>'
print '</head><body>'
Don't allow for easy expansion of webportage's look/feel. Following the
model-view-controller design pattern the "view" would be completely abstracted
into templates which are expanded based on how the other two facets of MVC
interact.
Currently you are using a hacked up version of portage that also hard codes HTML
into print statements, in my opinion your search class needs to have an extra
layer in between it and portage, so it'll be able to expand when portage
changes.
For example when you initialise the search class:
def __init__ (self, ...):
self.portageInterface = PortInterface()
And all interaction with portage would be "proxyed" through your interface,
i.e. a line line:
full_package=portage.best(portage.portdb.xmatch("match-all",match))
Would be translated to:
full_package=self.portageInterface.best(self.portageInterface.xmatch("match-all",match))
Using an interface intelligently could mean that in the future the only thing
you would have to changed would be how the interface actually interacts with
portage.
I hope I've provided some good ideas that aren't to obvious or useless :-) -- I
think the idea of a web interface to portage is really cool, I'd like to see
webportage come to fruition but making good decisions on design now will help it
be much more successful in the future.
Toodles.
