Getting environment variables in QML

[Martin.Wells]

I saw help documentation https://doc.qt.io/qtcreator/creator-qml-modules-with-plugins.html
I hope to get environment variables （QML_PUPPET_MODE）in qml

But I have no way
Whether it can only get the environment variable on the c++ https://forum.qt.io/topic/80788/calling-environment-variables

In your main.cpp file you can grab the env vars using QProcessEnvironment and add them as a context property...

app.getEngine().rootContext()->setContextProperty("env", QProcessEnvironment::systemEnvironment().toStringList());

This is pretty raw and they will still need parsing so maybe you'd want to do that and then pass in a QVariantMap instead.

In your main.qml you can try this by printing env in, say, Component.onCompleted

Yes you can get this environment variable from C++ qgetenv("QML_PUPPET_MODE") .
Then you can add it in the current QML context:
app.getEngine().rootContext()->setContextProperty("QML_PUPPET_MODE", qgetenv("QML_PUPPET_MODE"))

@kindid
Thank you this is a good idea.
