I'm curious why you'd want to do this when most all the rest of the
Fedora web infrastructure involves python.
There's /nothing/ wrong with using another web development platform if
you like it better.
Fedora should not have any language preferences.
Despite being a Python fan, having been on the wrong side of language
wars before, I won't support them, and they are wrong for lots of reasons.
However you make one very good point below:
The problem is that I cannot find a suitable Ruby parser for kickstart
files and writing one from scratch is what I'm trying to avoid.
Could someone please point me to the correct direction here.
Plan B is to switch to Django, which would enable me to use pykickstart.
pykickstart is the canonical kickstart file parser, being used by at
least a half dozen projects here. If you have to use another one or
write your own, you're going to have to play catch up when I need to
make changes to it.
That point is Anaconda is itself using pykickstart.
Fortunately though, there's absolutely no reason something building
kickstarts /needs/ pykickstart.
It's just as simple to build a system that /templates out/ kickstarts
from any arbitrary templating framework.
(Cobbler already does this, using Cheetah, though you could pick erb).
In the case of pykickstart, this is nice, because pykickstart running on
EL 4 can't create a Fedora 11 compatible kickstart anyway.... it doesn't
know about the new tags.
With a templating system, you could run your kickstart generator on any
platform, and it wouldn't matter what version of pykickstart you had.
Of course, if you want to /parse/ kickstarts and not just generate them
you need pykickstart, no doubt.
Yet, if you are just building a tool that generates kickstarts -- which
is what the input to livecd-creator and such really is -- and it's not
complicated -- I really don't see any need for a parser there.
The parser would be useful if you wanted someone to upload their own
kickstart and then make programmatic changes to it -- but, if you're
making a live CD or whatever, I'm not sure that's required or even all
that useful.
