Goneovim cannot display cmdline_popup

[przepompownia]

I use master version of Neovim, built from sources everyday. After numerous bugs with redrawing from some moment (on Wayland) I switched from nvim-qt to goneovim (https://github.com/akiyosi/goneovim).

Looking into rcarriga/nvim-notify#5 and neovim/neovim#16396 I decided to check what it is Noice. Unfortunately, cmdline_popup turned out not to work in Goneovim. In terminal (kitty) command line popup works.

If you can reproduce it, then probably we need to warn users similarly to Neovide (docs + checkhealth).

Probably the problem is not as general as I described it above: I can display nui input:

require('nui.input')({position = '50%', size = {width = 50}}, {prompt = 'Goneovim > ', default_value = 'works'}):mount()

Please note that the command still displayed in nvim's built-in cmdline. The same in terminal:

goneovim.mp4

I can also reproduce it with the minimal config /tmp/noice-min.lua from https://github.com/folke/noice.nvim/wiki/Minimal-%60init.lua%60-to-Reproduce-an-Issue

goneovim --nvim ~/tmp/nvim-from-src/bin/nvim -u /tmp/noice-min.lua

Most likely a Goneovim problem. Especially since it works in Tui.

Goneovim externalizes multigrid. With that ext enabled, Noice cant work

[folke]

I've added additional health checks for multigrid until that is fixed on the Neovim side.

@folke thanks for adding warning mesages and checkhealth, especially to avoid confusing new users. I never had not need to read ui.txt but maybe it's the time.

It's a chance that I can switch back to neovim-qt on which Noice displays cmdline_popup correctly.

In theory it should work, but something currently prevents messages and cmldine events when multigrid is enabled. See neovim/neovim#21068

[folke]

I have a Neovim PR that fixes the problems with multigrid, but Goneovim will also need to make a change.
