When auto-completing with neovim's LSP, whenever selecting a menu entry from the auto-complete list a scracth/preview buffer is created, even if empty:

How can I disable these buffers specifically for auto-completion ?

I'm aware of previewheight; setting it to 0 doesn't seem to have any effect, and even if it would, it would disable the preview buffer everywhere whereas I just want it disabled for auto-completion.

  • Try :help 'completeopt', though IDK if NeoVim baked in the preview flag there or not.

  • @D.BenKnoble yep, completeopt exists and defaults to menu,preview; setting it to menu fixes the issue; if you make that into an answer i'll gladly accept it

You should be able to use :set completeopt-=preview to remove this behavior.
