Question

Hi,

I tried to create some links to published iCal calendars in a topic on our local TWiki, but the link was not recognised. It's because the link protocol is webcal:, and this is not recognised in TWiki.pm, where the $linkProtocolPattern variable is hard-coded to a specific set of protocols.

It was easy enough to edit TWiki.pm and add webcal to $linkProtocolPattern.

But I thought I would try and be clever and make it a variables in TWiki.TWikiPreferences as a variable called LINKPROTOCOLPATTERN, then use TWiki::Prefs::getPreferencesValue("LINKPROTOCOLPATTERN") to initialise it. Unfortunately, it doesn't work.

Have I missed something?

Is this even a good thing to do? Maybe the preference should be additional protocols?

Thanks for any advice.

Answer

As you found out, adding this to $linkProtocolPattern in TWiki.pm is the easiest fix.

For your preferences variable solution you need to make sure that you get the value after the preferences are initialized, e.g. after &TWiki::Prefs::initializePrefs( $wikiUserName, $webName ); in TWiki.pm's initialize.
