Can QML files be obfuscated before bundling it in a sis file

If it doesn’t already exist, it will soon. Where there’s a will, there is a way. Unfortunately it seems you’re stuck in a game of cat and mouse. However, if you make it too difficult, the cat may not bother to chase.Don’t challenge me.
It would seriously be a cool project . Qt Resource Decompiler.
The only issue I see is that every compiler aligns his C arrays differently into the binary. So such a decompiler would always be limited to one or two configurations at a time.
If you need/want a real challenge I have a good one: a qml compiler! Or even better a QML to c++ generator.
That would be quite awesome! Not only do you get to keep the benefit of coding fast, you can skip the whole interpretive stuff, have the code in pure Qt C++ and you don’t have to worry about obfuscating the code :).
But I mean a lot of the code practices we use in QML are based around the fact that it is going to be interpreted. This would be hard to convert :\.
Maybe a .pyc or similar where it compiles the javascript but not in to C++.

It doesn’t need to be a 100% conversion or for every project.
It will convert optimize anything it can but it can still make use of the “script” run-time environment. I don’t think converting the “qml” would be a problem. Converting the javascript “portions” may prove not feasible.
The idea would be to use the qml as a replacement for the designer forms on c++ applications. For projects mostly based on qml/javascript it probably doesn’t make sense anyway.
tamhanna: What makes you think resources are in any way safe? There are tools available to introspect Qt applications that do quite a lot of neat things, including extraction of resources.
You might want to give this tool [gitorious.org] a try. In addition to resources it can help to examine the widget tree, etc. It is really amazing what you can do with Qt introspection.

Somehow since I started dealing with Qt I had this idea in the back of my mind that such tool would exist. Thanks for exposing it.
By the way, do you know of any good references of how to use “introspection” on your code? Introspection is widely used on java and .net projects but I haven’t seen much about how much can be done with Qt.

Don’t know why I hadn’t thought of it. Makes sense. The Type’s are directly translatable to classes with read/write/notify functions. So this could be compiled in and the app could possibly run faster :) Or at least load faster.
