using the RSS standard lib

F

Francis Hwang

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?

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

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.

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).

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,

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?

I'm glad to hear the indentation is changing, but the multiple newlines
in the outputted XML is more what I was talking about:

<?xml version="1.0"?>
<rss version="2.0">
<channel>
<title>talbott.ws</title>
<link>http://homeplace/</link>
<description>The Talbott family's blog.</description>
... 11 newlines ...
<item>
<title>Another post!</title>

<link>http://homeplace/weblog/permalink/2004/10/12/another-post.html</
link>
<description>&lt;p&gt;Stuff!!!&lt;/p&gt;</description>
...5 newlines...
<pubDate>Tue, 12 Oct 2004 20:35:02 -0400</pubDate>

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?

Thanks,

I added it and committed. Please try it.


I'll add convenient API for making new RSS soon. If someone
has some ideas, please tell me.

I think it is not work of RSS Parser. It is the talk of the
layer above RSS Parser.


Would you write multiple feeds parser? ;)

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?

It appears that 1.8.2 preview 3 has an rss/maker section, but when I
tried to run rdoc over this code I got a SystemStackError error:

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!

Strange: I just ran the latest RDoc against that directory. I got a
warning about an unexpected token in xml-stylesheet.rb, but no
SystemStackError.

Could you tell me if you see this with the latest RDoc from CVS?
