KDE Framework Port
Branches Creation
All port code must be stored in dedicated "frameworks" git branch for each project. Branch must be created from master.
$>git checkout master
$>git pull --rebase
$>git checkout -b frameworks
$>git push origin frameworks:frameworks
$>git branch -a
* frameworks

KF5 Repositories list is given below :
Kipi-plugins Refactoring
A lots of tools are not maintained since a while, other one have been never finalized. See the list of plugins which will be ported or not :
- Tools which can be ported as well :

- sendimages
- timeadjust
- metadataedit
- videoslideshow
- advancedslideshow
- flashexport
- kmlexport
- acquireimages
- calendar

- Tools in pending stage :
- dlnaexport <=== Needs HUpnp lib Qt5 port
- htmlexport <=== Nobody maintain this code since a while, but tool still used.
- photolayoutseditor <=== A complex but powerful tool. Will be complex to port.
- removeredeyes <=== We can share red eyes removal core implementation in libkface in way to share with other KDE applications and replace digiKam Image Editor tool by this code. A new digiKam BQM tool must be created. A GSoC 2015 project can be planned about this topic.
- Web export tools which must be factored (same settings widgets, common dialog, common high level interface to process import/export). Another GSoC 2015 project can be planned about this topic.

- mediawiki <=== need to port libmediawiki from extragear/libs/.
- vkontakte <=== require libkvkontakte from extragear/libs/.
- Tools never finalized (can be moved to attic for the moment) :
- imgurexport <=== require libqtkoauth from SF.net
- photivointegration
- jalbumexport
- wallpaper
- Tools obsolete (can be moved to attic for the moment) :
- batchprocessimages <=== replaced by digiKam BQM
- rawconverter <=== replaced by digiKam BQM
- jpeglossless <=== replaced by new digiKam core tool
- kopete <=== KF5 will use new API
- ipodexport <=== work only with very old Apple devices.
- galleryexport <=== Gallery web service is not maintained since a while. Gallery project is dead.

Recommendations
Porting to KF5 is divided in 4 stages:
1/ Change CMake files. Some Laurent scripts do this stuff. We use now ECM scripts collection from KDE core to manage dependencies and report on the console. Some macros disappear, and are replaced by new ones. For this job, it's recommended to look well all done in CMake files from libkexiv2 and libkdcraw already ported and polished.
2/ Port C++ code using KDE4Support. This include older classes from Qt4 and KDE4 to make transition faster. This will help to have quickly a code compilable, but this will generate a lots of deprecated warnings. First regression tests must be done at this stage to see if nothing is broken.
3/ Port C++ code to pure KF5. The goal of KF5 is to reduce KDELibs fingerprint everywhere, when it's possible. Qt API will be used in priority against KF5 API. But sometime, this will be not possible as well, without big changes. A lot of KDE API have migrated to Qt5 (as for ex : KUrl -> QUrl and kDebug ->qDebug). It's sound like KDELibs will become an incubator for new implementations which will move later to Qt. Also, to have the most of code using pure Qt5 will simplify future transitions more easy to do. Removing KDE4Support dependency will force to use non-deprecated KF5 API.
4/ Port C++ code to pure Qt5. Porting most of KF5 Api to use Qt5 instead is prefered, when it's possible. Another important change in Qt5 is the non-support of char pointer with QString.
In first stage we must use remove_definitions(-DQT_NO_CAST_FROM_ASCII -DQT_NO_CAST_TO_ASCII) in CMake script to compile code. These definitions force to not use deprecated QString methods.
Another definition to add while Qt5 porting is add_definitions(-DQT_NO_URL_CAST_FROM_STRING) about cast between QString and QUrl.
In last stage we must use remove_definition(-DQT_DEPRECATED_SINCE(5,0)) in CMake script to compile code. These definitions force to disable deprecated methods in Qt API.

Scripts to port code
Laurent Montel has written scripts to port CMake and C++ code to KF5/Qt5 and remove kdelibs4support dependency. There are available in this repository (see kf5 sub-dir).
Scripts must be applied in this order, with a test compilation between each one :
- Full safe scripts :
- convert-to-k4aboutdata.pl (first one to apply, this help to compile)
- adapt_cmakelists_file.pl (to convert CMake scripts, but code must don't be capititalized)
- remove-kde4support.pl
- convert-kicon.pl
- convert-kmenu.pl
- convert-kshortcut.pl
- convert-kcolordialog.pl
- convert-klistwidget.pl
- convert-kmd5.pl
- convert-kmenubar.pl
- convert-ksplashscreen.pl
- convert-kdebug.pl
- Less safe scripts :
- convert-kintnuminput.pl
- convert-kintspinbox.pl
- convert-ktextbrowser.pl
- convert-kfontcombobox.pl
