It will give you an overview of the solutions you're supposed to use to deal with some of the dependencies. Also, when splitting out a framework, it is part of being done to comply with the KDE Frameworks Policies, it will also need to follow this Epic Policies. Any framework in the staging area cannot move to its final place without following those policies. And last but not least, if you create a new framework, please consider being its maintainer as well. We need people to ensure the stewardship of all the frameworks. Existing frameworks Definition of done: No dependency on kde4support, kdecore, kdeui, kio, kparts... All unused dependencies are removed Tier1 modules depend only on Qt modules Library name is in CamelCase Modularized CMakeLists.txt [using extra-cmake-modules (ECM)] Installs a Config.cmake file for itself Does not install any Find*.cmake modules itself Calls feature_summary at the end of the toplevel CMakeLists.txt (see kcoreaddons for an example) All Find*.cmake modules needed by the framework and used also by other frameworks have been upstreamed to extra-cmake-modules (via the kde-buildsystem mailing list) or directly to cmake (via the cmake list). To make sure of this, do not append to CMAKE_MODULE_PATH, but set it. Does not set EXECUTABLE_OUTPUT_PATH anymore. Follows the policy on directory organization Unit tested Maintains source compatibility over kdelibs Does not use any Q_WS_* defines. Does not include config.h. Does not use QObject::tr() static calls, but only use QCoreApplication::translate(), tr() in a non-static way, or i18n() if the framework depends on ki18n.

Yet to be produced frameworks (foreseen tier and type, not set in stone): ... And probably more... Finalization tasks To be executed to complete the epic when all the frameworks are "done": Make sure it builds and runs against Qt 5.2 final Split into its own git module; pre-existing history will remain in the kdelibs repository and be accessible with git graft Produce a script or cmake file to recreate a kdeexamples tarball out of a set of examples directory in the frameworks Policies Strive for Source Compatibility Avoid removing API from the frameworks branch, even if it is replaced or deprecated. Prefer to implement the old API in terms of the new API. In some cases this is very easy. For example, many APIs in KGlobal will be replaced as part of the frameworks effort. KGlobal::charsets() -> KCharsets::charsets() KGlobal::dirs() -> KStandardDirs::global() (or something?) KGlobal::ref() / KGlobal::deref() -> QEventLoopLocker etc. Removing this API from KGlobal is not necessary in most cases, and it introduces a porting burden which is best avoided. There is unlikely to be a 1:1 mapping of old API to new API in every case, so how to implement the old API may not always be obvious. However, attempting to ensure that the older API remains useful should be at the front of our efforts and standards in the frameworks branch. Binary compatibility policy relaxed During the execution of this epic, the binary compatibility contraints from the global policy list is lifted.
