Plugin ignores file association

[Dodje]

Hello. I have a lua file with extension (.ds), sadly completion seems to be not able to associate it with lua and show complete menu

init.vim
...
autocmd BufRead,BufNewFile *.ds set filetype=lua
lua require'nvim_lsp'.sumneko_lua.setup{on_attach=require'completion'.on_attach}

echo &filetype returns 'lua'

Can you see if you can setup omnifunc completion and use that in the .ds file? I've done some testing on my side and find out completion-nvim seems to be attached but the server is not responding.

If I'm not mistaken, wrote this to enable

filetype plugin on
set omnifunc=syntaxcomplete#Complete

and CTRL-X CTRL-O shows

Ahh that is not coming from lsp. You have to set

au Filetype lua    setl omnifunc=v:lua.vim.lsp.omnifunc

Here is the result: without and

I also tried to work with lsp and set up some config, where I put paths from :LspInstallInfo and added ds file into filetypes property
