I recently transitioned from LanguageClient-neovim to built-in lsp support and completion using omnifunc. However I was enticed by the promise of auto-imports and completion snippets including function arguments, so I've been trying to integrate nvim-cmp. It requires a snippet engine so I installed vsnip, which seems to be working fine. However autocomplete is not working.
No matter what I do, it won't recognize any of the completion sources I try to install.
I don't see any errors at any point, it just seems to be silently failing; autocomplete does not appear when I type.
Here is the output from running CmpStatus:
# unknown source names
- nvim_lsp
I'm not sure what other debugging options are available to me at this point other than print-debugging the cmp plugin.
I have installed the following relevant plugins using pathogen:
- cmp-nvim-lsp
- cmp-vsnip
- nvim-cmp
- nvim-lspconfig
- vim-vsnip
- vim-vsnip-integ
I have gradually pared down my config file to a (hopefully reasonably) minimal representation, including removing all of the sources and mappings I tried to configure for nvim-cmp except lsp support:
syntax on
filetype plugin indent on
set runtimepath=$HOME/.config/vim,$VIMRUNTIME
execute pathogen#infect()
execute pathogen#helptags()
map / <leader>
