Window was closed immediately

[mrtnvgr]

Describe the bug When I try to open multiple windows at once, I get this error. How can I spawn multiple selection windows?

System information

• OS: linux
• Neovim version: nightly
• This is related to vim.ui.select backend.
• Dressing config:

vim.api.nvim_create_autocmd("FileType", {
    pattern = "DressingSelect",
    callback = function(args)
        vim.keymap.set("n", "<Tab>", "j", { buffer = args.buf })
        vim.keymap.set("n", "<S-Tab>", "k", { buffer = args.buf })
    end,
})

require("dressing").setup({
    input = { border = initlua.settings.ui.border },
    select = {
        nui = {
            border = { style = initlua.settings.ui.border },
        },
        builtin = {
            border = initlua.settings.ui.border,
        },
    },
})

To Reproduce

vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice) end)
vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice) end)
vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice) end)

What are you trying to accomplish? You cannot open more than one selection at a time because there is no way for the user to interact with more than one window at a time. If you need to perform multiple selections, you'll need to do that in sequence.

vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice)
  vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice)
    vim.ui.select({ "Yes", "No" }, { prompt = "1" }, function(choice) end)
  end)
end)

Yes, that's what I need! Is there a way doing this without nested functions? Ideally I would want to call them in a for loop.

for _, name in ipairs(names) do
  vim.ui.select({ "Yes", "No" }, { prompt = "Do you want to enable " .. name .. "?" }, function(choice) ... end)
end

If you want to call async functions as though they were synchronous, you'll need to use lua's coroutines. It's possible to use raw coroutines for this, but it would probably be easier to use an async lib. The most popular one I know of is plenary.async, but there are others out there.

Thank you so much! I will try it
