How to attach an external debugger for the .js files?

[sdsnatcher]

How can I attach an external debugger (like VSCode) to debug a .js extension for Tiled I'm currently working?

The javascript "debugger" command also just shows "Unimplemented code" on the Tiled console. IMHO, it should pause the script execution so you can connect a debugger and continue in step-by-step.

Unfortunately I think this is currently not possible. The only way I can find to debug JS code running in a QQmlEngine would be to use Qt Creator, compile Tiled yourself with "QML debugging and profiling" enabled, and then use the QML debugger in Qt Creator. However, I just tried to get this to work without success. See https://doc.qt.io/qtcreator/creator-debugging-qml.html if you want to try this yourself.

Otherwise, there is issue https://bugreports.qt.io/browse/QTBUG-55905 open about this kind of functionality, but it's been open for 5 years now so I don't expect such a solution to be implemented anytime soon. :-(
