And thanks to you for suggesting the idea and getting on it so quickly!

Hi,
thanks for opening the task! :) I was free and started to work on this some minutes ago, because I really like the idea, so I already added a change to gerrit, before anyone has the chance to discuss this :( But I hope, that we get such a function into ExtensionRegistration! Big thanks again for bringing this up.
Best, Florian

Hi Florian,
Thanks! For my immediate purposes, I think just doing the isLoaded() check will probably suffice, as I don't actually have any need to check versions at the moment. But I agree with your suggestion, extending the 'requires' section of extension.json does seem like it would be very helpful and extension developer-friendly, and that's a great idea.
I've opened a Phabricator task here https://phabricator.wikimedia.org/T117277, but feel free to tweak it if I've described something poorly or didn't tag it correctly - I've never actually created a task in Phabricator before.
Thanks!

You can, in your php extension code, so not inside the extension.json, check, if another extension is installed or not:
ExtensionRegistry::getInstance()->isLoaded( 'ExtensionName' );
There's also a "requires" section, which is parsed in extension.json, but it currently only supports MediaWiki core versions (it behaves like composer's requires section). I'm wondering, if dependencies like yours are widely used and if extending the requires section support to extensions would help to solve your problem (with that you could specify a specific version, a range of version or any version above a specific one, or all versions, too, so your VIKIJS_VERSION wouldn't be
needed anymore, too).
Would you like to open a task in phabricator to discuss this?
Best, Florian

Hi there,
I'm the primary developer of the VIKI https://www.mediawiki.org/wiki/Extension:VIKI extension and its two companion extensions, VikiSemanticTitle < https://www.mediawiki.org/wiki/Extension:VikiSemanticTitle%3E and VikiTitleIcon https://www.mediawiki.org/wiki/Extension:VikiTitleIcon.
I thought I'd take a look at converting these three extensions to the new extension registration < https://www.mediawiki.org/wiki/Manual:Extension_registration%3E format, but I ran into a problem. According to the documentation, the new extension registration does not support PHP constants < https://www.mediawiki.org/wiki/Manual:Extension_registration/Limitations .
I use a PHP constant to declare an explicit dependency on VIKI for VikiSemanticTitle and VikiTitleIcon. In my VIKI.php file, I declare:
*define( 'VIKIJS_VERSION', '1.3');*
And then in VikiSemanticTitle and VikiTitleIcon, I have a check that looks something like:
*if( !defined( 'VIKIJS_VERSION' ) ) {*
die('Error: The extension VikiSemanticTitle requires VIKI to beinstalled first.');* *}*
(As an aside, I also happen to use VIKIJS_VERSION as my version number, which I increment as I release new versions. But that's not as important.)
Because the new extension registration format doesn't support PHP constants, this no longer works, and I can't run VikiSemanticTitle and VikiTitleIcon alongside VIKI - the VIKIJS_VERSION constant is seemingly no longer defined, so any page load dies with the error
message above.
If I can't use PHP constants anymore, does anyone have a better recommendation for declaring explicit dependencies? Or should I just avoid migrating the VIKI extensions to the new registration format?
Thanks,
