[Qt-creator] Clang Model plugin interface

[Antonio Di Monaco]

Hi Bryan, 

yes, that could be a start, even if I cannot use the JSON compile database. 

What I'd like to have is just an interface class for clang parameters, that I can subclass and register in the Clang Model, in order to pass such options dynamically. 

Maybe the bug proves that I did not miss anything, and indeed there's no support for that yet. As I have to work on it in any case, cause it's a showstopper for me, I'll do my change proposal, when it's completed. 

Thanks, 

BR, 
A.

Hi Antonio,

FWIW I raised QTCREATORBUG-18402
<https://bugreports.qt.io/browse/QTCREATORBUG-18402> which *might* address
your needs, if implemented - I have yet to even think about how it'd be
done though.

Cheers, Bryan.
