@RaymondLim Done with initial review. This info.plist change appears to work just fine, but I'll wait for you to respond to @eugeneo 's comment before deciding to merge this change.

@eugeneo

in the case extensions add support to file types that are not currently supported.

Yes, my current change is exactly for file types that are not yet supported. So if an extension provides a pdf viewer or a video viewer, then the users should be able to view these file types with drag-and-drop on icon.

Thanks for pointing out "public.image" UTI. It's definitely better than listing individual image extensions, but I do have two concerns (or questions) for you.

• What is the key if we switch to "public.image"? I think it has to be LSItemContentTypes instead of CFBundleTypeExtensions that I'm currently using.
• "public.image" covers more extensions than we actually support in our preview image feature. Dropping an image file other than the extensions that I have will not show up in the image viewer in Brackets. So if we switch to "public.image", then users can use "Open With" in Finder for those image extensions that we don't yet supported. ( which I think is misleading)

Sorry, I overlooked the wildcard. I tested the change and found no issues.

I am not sure if there is a need to separately declare image extensions if there is a wildcard - I did not see any difference in my testing.

How about the key? Do you replace the key CFBundleTypeExtensions with LSItemContentTypes when you tested with "public.image"?

I did not try public.image - I tried your change as is and then tried your change after removing CFBundleTypeExtensions with the list of image extensions - saw no difference. In both cases I was able to drop to Dock icon and to use Open With... and then browse to the application.

I just re-tested with @RaymondLim 's original changes and with removing individual and/or all of the CFBundleTypeExtensions. From what I can tell, you do need to enumerate specific extensions in order support Open With of those file types. Otherwise, Brackets does not appear in the Open With list.

One observation: the Finder appears to cache the file type associations, so you'll need to be sure to do the following before any changes are recognized by the system:

• rebuild Brackets.app with your updated info.plist;
• run that just built Brackets.app; and
• force quit (and restart) the Finder.

Approving and Merging...
