Split the display text into regions and display with multiple phantoms

[timfjord]

Scenarios

1. 

Expected regions: nt"

2.

Expected regions: nil values and do

FYI, this wouldn't work if the completion is longer than lines in the view. So if the view is 3 lines long and the completion is 5 lines, it would need to be split into 3 regions.

Region 1: 1 Line Region 2: 1 Line Region 3: 3 Lines

I think he means inline completion gives a single phantom which contains text already in the view atm.

Yeah, the idea of this issue is to parse the completion text before displaying the ghost text.
Currently, we show the entire string from the payload, but, when, for example, you are in the middle of the line and there is a trailing text, most of the time the ghost text is confusing

Like on the picture above, the ( symbol shouldn't be part of the completion

I will add more details to the issue later on.

Also, most likely this issue is valid only for single-line completion.

I'll take a stab at this

There is also an extreme case when you a completion should be split into multiple regions.
I will try to send a screenshot when I reproduce it

@TheSecEng I've added some scenarios to the card description.
