grabbing rss or other type of feeds within lift

[Mark Essel]

trying to conjure up a similar functioning piece of code in scala to
grab my status from twitter.

(php)
$username = "victusfate";
$feed = "http://search.twitter.com/search.atom?q=from:" . $username .
"&rpp=1";
//echo $feed;
function parse_feed($feed) {
$stepOne = explode("<content type=\"html\">", $feed);
$stepTwo = explode("</content>",$stepOne[1]);
$tweet = $stepTwo[0];
$tweet = str_replace("&lt;", "<", $tweet);
$tweet = str_replace("&gt;", ">", $tweet);
return $tweet;
}
$twitterFeed = file_get_contents($feed);
echo stripslashes($prefix) . parse_feed($twitterFeed) . stripslashes
($suffix);

(.scala file)
var username = "victusfate"
var feed = "http://search.twitter.com/search.atom?q=from:" +
username + "&rpp=1"
<span>{ feed }</span>

stuck here tried Rome, and various other feed fetching libraries
without much luck (very new to the language and setup)

[Timothy Perrett]

mark,

take a look at: http://is.gd/1iUJN

That should provide you some guidance. I notice from your example your
trying to parse the twitter feed? Perhaps if you want to do something
with twitter you should consider a proper twitter api lib:
http://code.google.com/p/java-twitter/

Cheers, Tim

[Mark Essel]

Thanks Tim. will definitely check out the lib (not sure of licensing
issues, plan on developing a product with it)

[David Pollak]

Personally, I'd use Scala's XML parsing to parse the feed... skip the external library.

You may also want to look at the ESME code http://incubator.apache.org/esme/  There's an RSS reader and a Twitter poller in there.  The code is Apache 2.0 license, so you can use it without any license-related concerns.

I remembered this came up a long time ago as well:

Thanks David. I'm going with some direct calls for simplicity (along
the path you suggested).
along the lines of:

val rssFeed = XML.load( (new URL
(feedUrl)).openConnection.getInputStream )

One more oddity, I'm getting problems compiling normal scala code but
I can build lift projects (with scala inside them).

Something that I need to add in the config file like a path to the
scala binaries? (installed it in windows default spot)
for netbeans.conf
the netbeans_default_options var, adding
-J-Dscala.home=SCALA_HOME
where's SCALA_HOME supposed to point to?
I tried:
-D\"c:\Users\Dude Jones\.netbeans\6.7rc3\scala\scala-2.7.3.final\\"
where the binaries are no luck

Getting the error:

Lift, the simply functional web framework http://liftweb.net

Beginning Scala http://www.apress.com/book/view/1430219890

[Mark Essel]

Thanks think I'm making progress
following this:
http://wiki.netbeans.org/Scala
after the install of 6.7RC3, jdk, scala plugin, lift, maven (used it
to get a test lift project)
my lift project worked with scala code inside the project

but what I didn't do was set SCALA_HOME, my class path appended with
that SCALA_HOME\bin and finally
add that option -J-Dscala.home=SCALA_HOME to the netbeans.conf

hoping that does it.

Not for nothing but I wonder why all the hoops to get a compiler + IDE
has so many little steps. Eclipse I tried something similar with but
never even got the lift project or maven working.

I come from an old makefile /command line library background, and
recently .NET libraries, mains (various languages).
Netbeans is still new to me (used once before for gcc in cygwin).

Which maven plugin did you try for eclipse? M2eclipse works for me...

-------------------------------------

[Mark Essel]

Yeah Naftoli it was m2eclipse. May have been my failure to set
SCALA_HOME and the path properly.
I'll review it next time I do an eclipse setup (hopefully not for a
while now that netbeans is cooking with scala/lift)

Seriously, thanks much for all the feedback and help gents.

[Mark Essel]

ps found a nice code framework to help with my initial setup here from
Ted Neward
http://www.ibm.com/developerworks/java/library/j-scala06029.html
Will use some of those classes/objects to get started (Ted's cool with
it as long as I show him how it ends up)
