[TYPO3-dev] EM - Hook _before_ installing an Extension ...

[Stefan Geith]

Hi Devs,


Question 1:
is there a way to execute code of a extension, _before_ it is uploaded ?

Usecase:
Imagine, your extension needs some special php-modules to be loaded;
Then installation of this extension should be denied, if these modules 
are missing - Typo3-EM only checks for PHP/Typo3-Version and existance 
of extension-versions.

Is there any kind of 'ext_install_check.php' mechanism, that could
check prerequisites and return an error-message in case of errors?
If not: would this be worth to get implemented ?


Question2:
Is there a way to get additional information to the 'Information'-Page
of an extension ?
Output of something like 'ext_em_information.php' ?
This could be an alternative to the option above:
There could be checked of prerequisite of an extension - no matter if 
installed or not ...


Any comments / ideas ?
