Is anybody out there using the RSS standard lib that comes with Ruby 1.8.2? I'm trying to make use of it but am finding the lack of documentation frustrating.
Also, is it possible to use this to do parsing of multiple feeds each of a different version? Require "rss/2.0" seems to force me to use 2.0 parsing for all my feeds, but what if I'm parsing a bunch of feeds with different versions?

Is anybody out there using the RSS standard lib that comes with Ruby
1.8.2? I'm trying to make use of it but am finding the lack of
documentation frustrating.
It's worse when you try to read the source, since it's not conformant
to the rest of the Ruby codebase standard.
Also, is it possible to use this to do parsing of multiple feeds each
of a different version? Require "rss/2.0" seems to force me to use 2.0
parsing for all my feeds, but what if I'm parsing a bunch of feeds with
different versions?
I haven't seen anything that allows you to do anything smart like this.

Straight from Tutorial.en from rss-0.0.9:
Include this if you want to handle RSS 0.9x/1.0/2.0:
require 'rss/1.0'
require 'rss/2.0'
You don't need including it because of RSS 2.0 includes RSS 0.9x:
require 'rss/0.9'
Sure, there's no documentation in /usr/lib/ruby/1.8, but there's
certainly documentation available. Look for rss on raa. Didn't take
much work. Good luck,

I'm using it every day to create RSS feeds from non RSS sources (such as CVS commit logs and amazon sales ranks).
There's documentation and examples of using it in the new PickAxe (he says, at the risk of sounding like a salesman).

I guess I just saw no RDoc over at the Ruby-doc.org standard lib page ( http://www.ruby-doc.org/stdlib/ ) and assumed that was the end of that. I always forget to look over at RAA, so thanks for that reminder.
May I humbly suggest that at least there could be a pointer to the tutorial buried in the .rb files? I mean, I'm familiar enough with Ruby that I should've thought to look at RAA, but not every Ruby user is.

Question for the group, while we're on the topic: I've just started using it to generate feeds myself (for the blog I'm writing)... is there any way to get it to output a bit cleaner? There's tons of extraneous whitespace in the generated XML.
Thanks,

Try using FeedForAll http://www.feedforall.com for rss feed creation. Makes
things a whole lot easier.

That tutorial doesn't hold for ruby1.8. Ruby1.8 doesn't have
a rss/maker, so the whole encoding section at the bottom isn't too
helpful. No idea if the parsing part is good.
Anybody know what happened to rss/maker?

How exactly would anybody know WHICH of the many RSS libs on the RAA was
adopted into ruby?

Yeah, the documentation of the standard libraries is lacking for many
libraries (look at mkmf for example...it's a pain trying to figure out
what you can do with it).

Which of `tab indent' and `two or more new-lines' is your
problem? Or both?
If your answer is the first one, please wait. I'll change
`tab indent' of outputted RSS and source code to two spaces
indent.

Might it not be better to ensure that such documentation is readily available from the Rdoc files in the first place? If something is being included as part of the standard library then its documentation should be complete and easily accessible.
Why should one have to think of it as a stand-alone project in order to locate the docs?

It doesn't affect the function of the feed at all, but I guess I'm just a bit picky about the form of things. Is there already a way to clean this up? If not, can you add one?

Ok, I still don't know what happened, but I think the darwinports version of
the preview doesn't have rss/maker, but has the rest. I'm a little confused.
Anyhow, I downloaded and manually installed rss1.0 from the RAA, and I have
rss/maker.
Sorry!

I installed ruby from cvs, I don't see any problems with it, just a few
"unexpected token" errors.
The one that was dying with stack was version:
RDoc V1.0pr1: 2004/04/04 23:19:58 (1.1.2.6)
But I guess the latest is doing good.
