in reply to How to make dynamic result in META varriable in perl template toolkit

You've only posted HTML. If this is really a problem of Perl inserting a variable title, consider below:
use strict; use warnings; my $pageTitle = 'variable title text'; print qq[ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http:/ + +/www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>$pageTitle</title> <meta name="generator" content="Ipad2 and iphone accesories" / +> <meta name="author" content="cloudsandcolors.com" /> ]; print qq[rest of properly formatted web page];
The above will allow you to insert variable text in the title, if that is all you want.

I suspect, however, you want something cooler, like dynamic update of <title> after page is already loaded. If I am wrong, my code above should help.

    Thanks for the post, my page is loading in template toolkit like
    [%content wrapper html + layout%]

    my header and footer were loading after all the content were created so bringing the variable to template was good and it started working.

    Thank for your time

[ambrus]: Corion: well Prima::Object says something like that the cleanup method will send an onDestory message and that you can't get more messages after cleanup, or something.
[Corion]: ambrus: Yeah - I don't think the deep source dive will be necessary if things are implemented as simple as they could be :)) And hopefully I won't need (more) timely object destruction. I can update the screen at 60Hz and hopefully even do HTTP ...
[Corion]: ... transfers in the background. Now that I think about it, this maybe even means that I can run the OpenGL filters on Youtube input :)
[ambrus]: Corion: I mentioned that the unix event loop of Prima always wakes up at least once every 0.2 seconds. Have you found out whether the win32 event loop of Prima does that too?
[Corion]: ambrus: Hmm - I would assume that the onDestroy message is sent from the destructor and doesn't go through the messageloop, but maybe it is sent when a window gets destroyed but all components are still alive...
[ambrus]: Corion: partly deep source dive, partly just conservative coding even if it adds an overhead.
[Corion]: ambrus: Hmm - no, I haven't looked at wakeup intervals ... I wonder why it should want to wakeup periodically because it gets a lot of messages from the Windows message loop (on Windows obviously)
[ambrus]: (Alternately a deep source dive and then rewrite that event loop to make it better, and then as a bonus you get an idle method.)
[ambrus]: The 0.2 seconds wakeup is likely a workaround for some bug, but I can't guess what bug that is.
[ambrus]: It's been there since Prima 1.00 iirc
