Hi, I am currently working on improving the calculator runner, by adding an optional dependency on libqalculate. If the library is found, the calculator runner will be built against libqalculate and it will support "advanced" operations (such as currency conversion, unit conversion, equation solving, ...). Otherwise it will fall back to the existing code that uses QtScript. I have tested the runner for some weeks now and it is stable.
I would like to hear some opinions about these points: - currently there are two calculator plasmoids, with and without libqalculate support (btw I am the author of the qalculate one). I think that we could use a similar approach here as with the runner, i.e. have a unified calculator plasmoid that optionally depends on libqalculate. - a Qalculate backend for Cantor is currently in playground (not developed by me). It is already quite stable and I think It would be nice to have it included in SC 4.5. - one problem is that the runner, applet and Cantor backend have some duplicate code (e.g. evaluation options, support for QString, ...). As Aaron suggested some time ago, maybe it is worth it to add a wrapper library for libqalculate use in KDE (something like libkdeqalculate, feel free to suggest a nicer name ;). Where should this library be placed? Would kdebase/workspace/libs be an appropriate place? Of course I volunteer to take care of these tasks before 4.5 freeze ;) Thanks for your attention, Matteo
