Question

Can any one let me know whether Twiki now supports Headline Plugin??? I did evrything that was said in the installation of Headline Plugin. But I coudn't find any news feeds into the HTML. Installed Headlines Plugin and called the plugin using the following.

%HEADLINES{ href="http://slashdot.org/slashdot.rdf" }%

which ideally should pull the news feed and display it but I just got

$channeltitle?

I looked at the logs but not much information in it. I'm ale to view the rdf file in a browser so don't think firewall is a problem...I coudn't figure out what is goin wrong as there are not much debug statements . Also I did read on the documentation that Headline Plugin may not be supported in future releases of Twiki as it uses undocumented Twiki: getURL() .. Please help.

Answer

The HeadlinesPlugin is specifically written for TWiki, yes, TWiki does support the Plugin

The getURL() call is not the problem, is available in all TWiki versions since 01 Dec 2001.

Set the debug flag in the Plugins topic, see data/debug.txt if the Plugin initialized OK. You should see a - TWiki::Plugins::HeadlinesPlugin::initPlugin( Web.topic ) is OK message.

Try also other news feeds. If needed, so some TWikiDebugging.

Thx Peter, I tried out the Twiki Debugging, I think I got the problem. Basically the getUrl function for some reason is always returning empty string.

my $text = getUrl($theUrl);

for example when I use a feed http://www.ifr.us/backend.php i.e $theUrl , returned value in $text is empty . What could be the reason?? Can you please suggest.

its me again, I track down the exact problem now. getUrl function was not at all being called from HeadlinesPlugin.pm script. reason being it was called directly as below

my $text = getUrl($theUrl);

but when I specified the path of the function it did work..

my $text = &TWiki::Net::getUrl($theUrl);

but i'm getting into one more problem I get the following error...

Software error:

Bad arg length for Socket::pack_sockaddr_in, length is 0, should be 4 at /usr/local/lib/perl5/5.8.0/i686-linux/Socket.pm line 373.

line 373 of Socket.pm is

372: croak "usage: sin_sv = sockaddr_in(port,iaddr))" unless @_ == 2; 373: pack_sockaddr_in(@_);

i'm a novice in Perl programming and this is definetly out of my scope. Can anyone pl provide a solution??

The problem was due to the Web Proxy , I changed it to the correct value in TWiki.cfg . Evrything is working fine now. Thanks PeterThoeny for debugging hints.
