How to make mini.completion work with nvim runtime completions

[craigmac]

Right now when doing vim.api.nvim in a lua buffer I don't automatically get results from the nvim api, but if I do vim.api.nvim<C-x><C-o> to trigger built-in (in a pretty recent nvim commit b:omnifunc is set to v:lua.vim.lsp.omnifunc if it isn't set).

If I were to explicitly do setlocal omnifunc=.. like described in the mini docs (inside on_attach() lsp callback), then would I still get the 2-stage completion feature?

Here's my lua-language-server settings (using neovim/nvim-lspconfig):

require('lspconfig').lua_ls.setup({
  settings = {
    Lua = {
      runtime = {
        version = 'LuaJIT',
      },
      diagnostics = {
        globals = { 'vim' },
      },
      workspace = {
        library = vim.api.nvim_get_runtime_file('', true),
        checkThirdParty = false,
      },
      telemetry = {
        enable = false,
      },
    },
  },
})

First of all, thanks for library = vim.api.nvim_get_runtime_file('', true), line. I didn't update my Lua Lsp setup in a while, mostly because it works and I tend to read Neovim help docs anyway. But replacing my previous workspace.library with this one made it better. Maybe even a bit too much, as it suggests from plugin codebases, so we'll see.

Second, I am not sure what to tell you. I've just reproduced vim.api.nvim autocompletion with your 'lua_ls' setup and plain require('mini.completion').setup(). Let's try to be on the same page:

• Do you suggestions show if you press <Ctrl> + <Space> (default mapping for triggering two-stage completion)?
• What does executing :echo &completefunc and :echo &omnifunc show?

I should have produced a minimal repro first, it's something in my runtime messing with it because I stripped it back and see it is working as intended, thanks!

Through bisect I've narrowed it down to this bit of code being uncommented in my init.lua, which causes the issue:

local MyAugroup = vim.api.nvim_create_augroup('MyAugroup', {})
vim.api.nvim_create_autocmd('BufEnter', {
     group = MyAugroup,
     command = 'if &bt ==# "terminal" | norm! a | endif',
     desc = 'Automatically enter terminal-mode when entering a terminal buffer'
})

@echasnovski I'm not sure how this is not compatible with the mini.completion BufEnter event settings. Do you see how setting this autocmd would mess it up? Is there a hidden terminal running or something, or maybe it's a load order thing with this autocmd?

[echasnovski]

No, can't think of anything why this should be incompatible with 'mini.completion'.

Is there a reason you don't use autocmd TermOpen * startinsert?

[craigmac]

Right. This is my error in transferring over some older vim script stuff, thanks for the hint!
