Issue Details

using vim9 it works find

but If I use neovim-0.9

no function parameters show on screen?

• What did you do?
  pure vim-9 and nvim-0.9
  install only one plug Youcompleteme
  it shows different

1. vim -Nu /path/to/YCM/ycm_vimrc_minimal
2. :edit test.py
3. Enter insert mode and type .....

• What did you expect to happen?

nvim show the function parameter the same as vim

Output of vim --version

vim 9
neovim 0.9

Output of YcmDebugInfo

the only difference
vim:

-- Server logfiles:
--   /var/folders/05/dfw4d4ds0nx2xyyn7yt5ky3r0000gn/T/ycmd_56063_stdout_dnlp9nq1.log
--   /var/folders/05/dfw4d4ds0nx2xyyn7yt5ky3r0000gn/T/ycmd_56063_stderr_os0ffmbd.log
-- Semantic highlighting supported: True
-- Virtual text supported: True
-- Popup windows supported: True

neovim:

-- Server logfiles:
--   /var/folders/05/dfw4d4ds0nx2xyyn7yt5ky3r0000gn/T/ycmd_56333_stdout_b9d9ylww.log
--   /var/folders/05/dfw4d4ds0nx2xyyn7yt5ky3r0000gn/T/ycmd_56333_stderr_l9_wtfev.log
-- Semantic highlighting supported: False
-- Virtual text supported: False
-- Popup windows supported: False

does it cause by neovim not supporting Popup windows supported or Virtual text supported?

[Boris Staletic]

Please post the entire :YcmDebugInfo. I have a suspicion that you are not running clangd at all.

Signature help is not supported in neovim. See them docs. Or upgrade to vim.
