[TYPO3-dev] How to make it right?

[Christian Opitz - Netzelf]

Hi list,

I've been watching the development of 4.3, extBase and FLUID for a while 
now. Actually i have to write a bachelor thesis about developing an 
extension for TYPO3 and i'd rather write about developing in FLOW3 
architecture then the regular one but OTOH i want to use my extension in 
4.x installations too.

At the moment i'm using the gimmefive component on which i like that 
it's possible to include in an extension and users don't need to install 
it before. But to be honest: the view rendering is a real gap compared 
to other frameworks or FLUID. Due to that i wrote an own view renderer 
that let's me use some logic in templates:

    public function assign($varName, $value) {
        $varName = str_replace(array('$',' ','/','\\'),'',$varName);
        $name = strval(trim($varName));
        if (strlen($name) > 0) {
            $this->vars[$name] = $value;
        } else {
            throw new Exception('Name for the assigned variable 
"'.$varName.'" is of the wrong type or contains restricted chars.');
        }
    }

    private function renderPHP($templateFile) {
        extract($this->vars);
        ob_start();
        @include_once($templateFile);
        $templateContent = ob_get_contents();
        ob_end_clean();
        return $templateContent;
    }

I really want to use a template engine and FLUID seems growing to a good 
one.

My major question is if it's possible to use extBase and/or FLUID in 
minor versions then 4.3? Probably i could test this by checking them out 
and trying it on my own but maybe s.o. already has a clear answer...

I'd apreciate if someone could give me a hint about which of the 
concepts arround i should use for development of a stable but future 
ready extension.

Thank you a lot
