Question

I have problem with saving of topics in my perl script.

reading of topics (no problem...) :
$text = TWiki::Func::ReadTopicText($web,$topic);

$text modified somehow...

and saving :
TWiki::Func::saveTopicText($web,$topic,$text,'1');
> Access to CHANGE ... for TwikiGuest ... is Denied

1) How twiki functions find out the name of user which operate with Twiki::func functions ? I anticipate that $session variable do this but i would like to see some pieces of code... how initialize $session in perl script ?

alternative - 2) Is possible use some Twiki function which is able to save topics and ignore permission settings (and using RCS system) ?

This script will start every night and actualize some topics (user topics&groups - ldap synchronize, and topics on the Project web - synchronize some data from database etc..).

thank you

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

If you can, then use the TWiki::Func API from the context of a plugin, which sets up the session for you.

If you are writing a stand-alone script, you can take inspiration from a range of Contribs that build sessions (such as MailInContrib, PublishContrib etc) or simply review the code of tick_twiki.pl in the tools directory. The API of the Store module provides methods for reading and writing topics. However i strongly recommend you do not use internal APIs, as they are subject to change.

If you want to use TWiki::Func methods from a perl script, then you have to fool TWiki into thinking you are callling them from a Plugin. You can so this by setting $TWiki::Plugins::SESSION to point to the TWiki object, e.g.

   my $session = new TWiki();
   $TWiki::Plugins::SESSION = $session;
   ... can now call TWiki::Func methods ...

How about "upgrade to TWiki 4.0" (bet you saw that one coming )

If you want your external script to execute as if it was run by the authorized user you can initialize your session like this:

   my $session = new TWiki( "TWikiName");
   $TWiki::Plugins::SESSION = $session;
   ... can now call TWiki::Func methods ...
