That is because it is a shell, and needs to be able to execute files just like bash (your shell scripts should always work regardless of your choice of shell). I fully agree that qmlsh, which you are welcome to start ;), should allow a #! syntax for its source files. I have written scheme scripts and they do not treat #! specially. I needed to use an arcane starting line which starts with a ;, which is fortunately both the scheme comment char and a noop for bash.

And even more so to the hordes of Meego hackers already banging at > the gates ;-) Without #!, QML is still an extremely nifty tool for writing script style GUI applications. And from the GUI perspective, the important shortcut is that the QML interpreter is registered to open QML files when you click on them. QML is not currently recommended for creating command line UIs, and so it is not a very high priority to cut out the couple of extra chars required to type 'qml' before the file name. We do hope that Meego hackers find QML useful, but QML is simply not a shell scripting language. Not yet at least. -- Alan Alpert Software Engineer Nokia, Qt Development Frameworks _______________________________________________ Qt-qml mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-qml
