Extensions API: enhance DecorationOptions with a custom element

[wmaurer]

vscode.DecorationOptions allows for a hoverString, but I would like decorated ranges to display a text popover text that doesn't require hovering.

This would allow me to develop an extensions equivalent to atom's jumpy

[wmaurer]

@alexandrudima To further refine what I'd like to be able to do:

• instead of a hover text, be able to be able to define a html string, e.g. "<div class='jumpy label'>aa</div>"
• be able to define the jumpy and label CSS classes
• also allow inline styles on the div element
• be able to position the div element relative to the decorated range, i.e. horizontal and vertical offset
• should also work with ranges of zero length, i.e. Range(new Position(0, 3), new Position(0,3)) (this currently works with hoverString)
• be able to programatically define whether the hover element can be displayed or not (possibly via inline style? or by setting the string property to undefined?)

Any feedback on the likelihood of this being implemented would be appreciated.

With this such feature, I could also implement the editor rulers via extension (if the VSC is not going to implement #1673 ) properly.

Instead of this...

Could be this...

Migrating alm.tools to monaco (:heart:) PR alm-tools/alm#121

I had a working version of jumpy in alm with codemirror

Will try and figure out how to add this to monaco 🌹

What an amazing job you are doing, I wasn't aware of the alm suite. Can't wait it to use in on vscode. tks.

I want to write a jumpy too, but don't have any better api to show some label on document text.

[Brakkar]

Please keep us informed here guys, if you manage to get jumpy like into vscode

Jumpy allows just to move to the beginning of the word. It's better to support jumps to any symbol. https://github.com/easymotion/vim-easymotion is a good example of such functionality.

Ok, so it seems that since I created this issue, the API has improved somewhat, and DecorationOptions supports more configuration, including a contentIconPath.

DecorationOptions could still be improved, but as far as I'm concerned this issue can be closed - I'll consider raising a new issue for further improvements.

BTW, if anyone's interested, I've created a slightly buggy but usable Jumpy extension: https://marketplace.visualstudio.com/items?itemName=wmaurer.vscode-jumpy
I'll continue to work on this extension to make it better.
