可以看看 [yapf](https://github.com/google/yapf)、[Git Hooks](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks)?

good idea, I'll look at it (maybe take times, quite busy these days). also, feel free to send pr.

same here, gentoo with qt 5.12, and i got error message like this: ``` plasmashell: relocation error: /usr/lib64/qt5/qml/QtQuick/XmlListModel/libqmlxmllistmodelplugin.so: symbol _ZN3QV46Object12insertMemberEPNS_6StringEPKNS_8PropertyENS_18PropertyAttributesE version Qt_5_PRIVATE_API not defined in file libQt5Qml.so.5 with link time...

better support for cross-compilation?
