Hello,<br>
<br>
as suggested by Aaron in a previous discussion, I am having a look at the<br>
calculator runner with the purpose of extending the capabilities of the runner<br>
by using libqalculate when it is available, otherwise falling back to the<br>
currently used 'qscript' method. So here are my questions (sorry if some of<br>
them are stupid ones...):<br>
* how should I detect the presence of qalculate on the system? Should I let<br>
CMake find the library and then use the preprocessor (#ifdef, ....) thus making<br>
it a compile-time optional dependency?<br>
* it was mentioned that thread safety is important in this case. How can I find<br>
out if libqalculate is thread safe?<br>
* I think it would be nice if the runner respects the same settings of the<br>
plasmoid (if it's being used). Is there a way to do this, apart from reading<br>
the plasma-desktop-appletsrc file?<br>
<br>
BTW, while looking at the code I found a bug in the runner. The expression<br>
'e+' is interpreted as '^' instead of '*10^'. So if you type 2e+2 you<br>
currently get the wrong result (4 instead of 200). The same applies to 'e-'.<br>
