I've been thinking about this problem on and off for a while. I think that one of the issues that is being bumped into with using Composer in core is that core is both a library (or really collection of libraries) and an application. I believe that the composer.json file was taken out of core to make it easier for consumers of MW the application to use composer to manage extensions in their local install via composer. This supports Joroen's use case of allowing folks running a MW instance to manage their extensions using Composer. The side effect is that it removed the ability to use Composer to manage external components used by MW the library which is Tyler's proposed use case [0]. I have used Composer with both applications [1] and libraries [2], but I've never tried to make a single project serve both roles. Finding a way to separate MW the library from MW the application may be a solution to this conflict. I don't think this would be a trivial project, but it doesn't seem impossible either. There would be several installation use cases to work through for a successful conversion: Foundation wiki farm, developer installs, consumer install via packagist, consumer install via tarball, etc. [0]: https://www.mediawiki.org/wiki/Requests_for_comment/Third-party_components [1]: https://git.wikimedia.org/summary/wikimedia%2Fwikimania-scholarships [2]: https://packagist.org/users/bd808/ Bryan -- Bryan Davis Wikimedia Foundation <bd...@wikimedia.org> [[m:User:BDavis_(WMF)]] Sr Software Engineer Boise, ID irc: bd808 v:415.839.6885 x6855 _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
