[TYPO3-50-general] Valid Package Keys

[Malte Jansen]

Hi David!

Check out the FLOW3CGL on forge.typo3.org


Until now we are checking it like this:

|^[A-Z][a-zA-Z0-9]+$|

But I'm pretty sure the numbers of characters a PackageKey must have, 
will be raised.

Until now there are no special characters allowed, because you have to 
use "UpperCamelCase"-style for your package name.

All code should be human readable. So vars- and class-names etc. must 
consists in common of a-zA-Z0-9. But check the FLOW3CGL.

Other unicode characters won't be allowed, because not you should create 
/search for a PackageKey with your Keyboard. So default language is English.

Here you can get the draft of the documentation.

Cheers,

Malte
