How to set cursor style on exit?

[leejy12]

I am using Neovim nightly on Windows. Here's my attempt to set the cursor to a vertical bar that blinks every 530ms.

vim.api.nvim_create_autocmd({ "VimLeave", "VimSuspend" }, {
  callback = function()
    vim.opt.guicursor = "a:ver1-blinkwait530-blinkoff530-blinkon530"
  end,
})

But this doesn't work, can anyone help me?

Changed in Nvim 0.12 , see

• The autocmd that reshapes cursor when quitting neovim does not work after upgrading to latest pre-release #36863 (comment)

see also #4396 (comment) , but use nvim_ui_send() with Nvim 0.12:

:autocmd VimLeave * set guicursor= | call nvim_ui_send("...")

The nvim_ui_send() method didn't work, but I created a workaround for PowerShell that doesn't rely on Nvim. It works by overriding the prompt function.

function Register-CursorResetPromptHook {
    if (-not (Test-Path function:\global:CursorResetOrigPrompt)) {
        Copy-Item function:\prompt function:\global:CursorResetOrigPrompt -Force

        $global:CursorResetPromptScriptBlock = {
            Write-Host "`e[0 q" -NoNewline
            CursorResetOrigPrompt
        }

        Set-Content -Path function:\prompt -Value $global:CursorResetPromptScriptBlock -Force
    }
}

Register-CursorResetPromptHook

Put this in your $PROFILE.

This is directly inspired from ZLocation module's code.

Same, nvim_ui_send also doesn't work!

(autocmd! [:VimLeave :VimSuspend]
          {:desc "[Cursor Style] Restore terminal cursor style"
           :pattern "*"
           :callback (fn []
                       (set GUI_CURSOR_CACHE (vim.opt.guicursor:get))
                       (set vim.opt.guicursor {})
                       ;; \x1b[?12l -> disable cursor blink
                       ;; \x1b[6 q -> set cursor style to bar
                       (vim.api.nvim_ui_send "\x1b[6 q \x1b[?12l")
                       nil)})

I use Alacritty + tmux. The only reliable way I've found to restore the cursor shape (bar without blinking in my case) is to use a shell hook:

For zsh add this to ~/.zshrc:

precmd() { printf '\e[6 q'; }

For bash add this to ~/.bashrc:

PROMPT_COMMAND='printf "\e[6 q"'

Use \e[5 q if you want bar with blinking.

Thanks, this works to me.
in ~/.bashrc

PROMPT_COMMAND="$PROMPT_COMMAND; printf \"\e[6 q\""

Same issue, none of the below work on 0.12 (or course, using PROMPT_COMMAND does work, but sending one more command on each prompt does not seem ideal?).

autocmd VimLeave,VimSuspend * set guicursor=a:hor20
autocmd VimLeave,VimSuspend * set guicursor= | call nvim_ui_send("\e[4 
autocmd VimLeave,VimSuspend * set guicursor= | call chansend(v:stderr, "\x1b[4 q")

Tested on both Alacritty + Tmux and Ptyxis. The response here #36863 (comment) is that it's the terminal job to restore to default.

infocmp -x $TERM | grep Se get me Se=\E[2 q (block cursor) which I suppose explains it (I am using an underline by default). So another solution could be to change Se at terminfo or tmux level.
