Scratchpad/KDEKDChart

Calligra, KMyMoney and Massif Visualizer (perhaps more) use KDAB's library KDChart/KDGantt. Because there is no public repo for these lib(s), the programs have a complete copy of the sources in their repos. Those copies get updated manually to newer version and also get custom patches. Not perfect.

Plan is to have the "public" version of KDChart/KDGantt in an own repo, maintained by KDE people.

Tasks

Name

KD* can not be used, something else will be needed. "kde-kdchart" working title for now. Proposals:

libkarta
KChart
KDiagram
(your proposal)

Perhaps split KDGantt and KDChart into separate projects, given they do not share code. A rename of the libs to KChart and KGantt could then directly be reflected in the repo name

Buildsystem

setup a CMake build system [Done]
remove qmake build system [Done] (some compiler flags still need checking if still relevant)

Repo location

Decide about location in KDE repos. Proposals:

Extragear/Libs
KF5 (does need license change to LGPL, see Licensing Policy)
(your proposal)

Clean up code

get rid of old code that's probably not required anymore, like libkdabfakes and stuff that's guarded by ancient QT_VERSION checks
ensure all relevant patches from Massif Visualizer, Calligra, ... are available in this version (Friedrich's version has MV & most Calligra commits added for KDChart)

Port programs to use it

Get rid of the custom copies, use this new library instead
