How to close popup when cursor on parent buffer moves?

[anuvyklack]

I am trying to create a popup window that will be closed on cursor move, but this code doesn't work:

local popup = Popup({
   enter = false,
   focusable = false,
   position = "50%",
   size = {
      width = "80%",
      height = "60%",
   },
   buf_options = {
      modifiable = false,
      readonly = true,
   },
})

popup:mount()

popup:on(event.CursorMoved, function()
  popup:unmount()
end)

Do you want the popup to close when

• the cursor inside popup is moved?
• the cursor on the buffer outside the popup is moved?

popup:on(event.CursorMoved, function()
  popup:unmount()
end)

What this does is, when the cursor inside the popup is moved, it unmounts the popup.

But what you want is something like this:

local autocmd = require("nui.utils.autocmd")
local event = require("nui.utils.autocmd").event

-- this is the `bufnr` where it cursor is currently at (where you're editing your file)
local bufnr = vim.api.nvim_get_current_buf()
autocmd.buf.define(bufnr, event.CursorMoved, function()
  popup:unmount()
end, { once = true })

popup:mount()
