Automatically reload local config files when changed

[naoliv]

It would be nice if JOSM could automatically reload local config files (validator .cfg or .mapcss, for example) when they get modified (using some file notification system for this).

That's something for Java 7: ​http://docs.oracle.com/javase/tutorial/essential/io/notification.html

That would be very helpful. When you edit and test mappaint styles, you always need to restart JOSM or delete and re add the style to JOSM after every little change to see the result. That is a bit annoying.

Concerning map styles, there is already a mechanism with mappaint.auto_reload_local_styles in the Map Paint dialog, which can be replaced by a generic WatchService approach.

Replying to Don-vip:

Thanks for the hint, that helps a lot. Though this does only work if the dialog is displayed in the sidebar.

[Don-vip]

Yes I plan to replace this feature by a better mechanism. But I'll keep the preference entry.

It still doesn't apply to local MapCSS validator files, right?

[Don-vip]

Not yet, work in progress :)
