This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
How to start?¶
The very first thing you need to do during development new extension is adding the dependency into your
ext_emconf.php file. Thanks to this, users who'll install your ext from TER via EM won't need to install the GeoPicker manually.
sample entry can look like this:
$EM_CONF[$_EXTKEY] = array( ..., 'constraints' => array( 'depends' => array( 'typo3' => '6.2', 'geopicker' => '1.0.0', // of course version number should be confirmed by you ), ..., ), );
Of course it would be best if you tested newest GeoPicker version and update the dependency, each time when you are gonna to publish new version of your extension.
