Support format on paste

[jrieken]

We should add support for format on paste. Idea is to simply invoke selection formatters when paste has happened.

On OS X, could this be mapped to "Paste and Match Style"? ⌥⇧⌘V

@rebornix Do you want me to get started on this? We already have the concept for formatting a range so, my plan is to do the following:

1. detect paste range
2. invoke range formatter

[rebornix]

@jrieken previously I implemented it in another way but we think that's not good, I'll follow your suggestions and do this again :)

Like @coreh I'm also interested to know whether this can be a command separate from paste so the user can choose which to use on demand (i.e. one keyboard shortcut for paste, one for paste + format)

Firstly, thanks for adding this, it's been the one feature I really missed from Sublime Text.

Having a play around with it, it seems to create two entries into undo history per single paste. I can't decide if that's a bug or a feature.

[rebornix]

@jakearchibald It's not a bug but I can't say it's a feature :( The behavior is consistent with FormatOnType or Save as we hook the formatting handler to Type/Save/Paste event, which makes it two entries in undo/redo stack. cc @jrieken

Another "is this a bug or not?"

If I paste:

self.addEventListener('fetch', function(event) {
  event.respondWith(
    promiseAny([
      caches.match(event.request),
      fetch(event.request)
    ])
  );
});

It adds a space between function and (event). I didn't expect it to do that.

@mjbvz I suppose what @jakearchibald mentioned is actually TypeScript formatter's default behavior, right?

Yes, you can disable this formatting using "javascript.format.insertSpaceAfterFunctionKeywordForAnonymousFunctions": false or "typescript.format.insertSpaceAfterFunctionKeywordForAnonymousFunctions": false
