LSP/DAP provided UI

[Kuinox]

One of the problem the draco project will reach is that there are various IDE/Text Editors (I will bundle "Text Editors with IDE from now on for conciseness), and to add various features, like a debugger view of all the running Tasks in a .NET program, we would need to have specific code for each extensions.

Worse, IDEs rarely have nice API that allows to quickly extend it's UI.

I propose a "shortcut", by moving the UI logic in the common components: the LSP/DAP.

The LSP/DAP would send UI windows defined in HTML/CSS (which is sadly the most supported cross-programs way of displaying things) to the text editor/IDE, and communicate with a IDE specific client.

While this isn't a small task, it will allow to make trivial to add complex windows in the compiler or the debugger.

The server need to:

• Send a first page, then send updates to that page.

The client need to:

• Create the window and display the html content
• Make the window elements somehow interact with the context of the IDE.

Other pending questions:
Do we want JS or not at all ?
How do we want to handle UI interactions (like animations) ?
