[Terminal] Cursor shape escape sequences not working

[caksoylar]

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.18362.86]

• What you're doing and what's happening: (Copy & paste specific commands and their output, or include screen shots)
  Using DECSCUSR escape sequences do not change the cursor shape, which is fixed to what it is set in profiles.json.

• What's wrong / what should be happening instead:
  Cursor shape changes like it does in conhost, see conhost above and Terminal below:
  

AFAICT all sequences here are supported in conhost, and larger values (e.g. echo -e -n "\x1b[\x37 q") changes it to the "legacy underscore" version. Also related #68.

Yep that's correct, the cursor sequences aren't hooked up quite yet for the terminal.

If someone wants to take their chances at implementing this themselves, I'd take a look at Terminal.h/cpp, TerminalApi.cpp, TerminalDispatch.cpp.

I believe these two are the methods that need to be Implemented in TerminalDispatch:

    // From TermDispatch.hpp
    virtual bool SetCursorStyle(const DispatchTypes::CursorStyle cursorStyle) = 0; // DECSCUSR
    virtual bool SetCursorColor(const COLORREF Color) = 0; // OSCSetCursorColor, OSCResetCursorColor

Hi! Is anybody working on this? I would like to take a stab at it!

In my version -- latest released to date, and with Powershell Core -- the cursor still does not change shape in vim on WSL.

I deleted a previous comment asserting that this is not fixed, which was incorrect.

However, it is true that neither Vim nor Emacs seem to be able to detect (or detect reliably and/or accurately) the capabilities of the terminal to enable the cursor behavior that one would expect after using the GUI versions of those programs.

I'm leaving this note for anyone who stumbles on this thread, as I did. You will likely need to amend your Vim or Emacs configuration to make cursor shape change as you expect.

If you use Emacs, you may try the evil-terminal-cursor-changer package (available in Melpa), though note that as of this time, that package will not correctly identify Windows Terminal as an xterm-compatible terminal, so you should set the XTERM_VERSION environment variable to any value (I did that from within my Emacs config), to force it to use the xterm escape sequences.
