Expose macOS native sharing dialog via ns-share

[xenodium]

The PR exposes the macOS native sharing dialog via ns-share.

Change unlikely to be accepted upstream until there's a linux equivalent, thus proposing to emacs-plus, my favorite build ;)

ns-share "does what I mean" (DWIM) by operating on either:

• Region text (any buffer other than dired).
• Current buffer file (any buffer other than dired an no region selected).
• Dired marked files
• Dired region files

A couple of sample screenshots:

Sounds amazing. Thanks a lot @xenodium ❤️

I see that there is some active discussions in the linked thread, so I'll wait a bit before merging. If in the end the alternative solutions would not be accepted, I'll just merge your PR. If the upstream solution will be not ideal - I am open to macos specific patch here.

Does that make sense to you? :)

[xenodium]

Sounds good. Looks like there's still a chance to upstream it, so let's indeed wait for the outcome of that.

@xenodium That's a nice one.

I will add it to https://github.com/daviderestivo/homebrew-emacs-head once it's stable enough :).
Thanks for having shared it ..

Still working through patch feedback, in the hope we can upstream 🤞

I guess I have found a little bug :).

When two buffers are visible the popup menu appears always in the first left buffer even if the selection is on the right one:

Oooh, OK, will take a look :)

@xenodium, once you have the fix, could you please open a PR for homebrew-emacs-head?
