E5113: Error while calling lua chunk: /home/hrq/.config/nvim/init.lua:64: Vim(let):E121: Undefined variable: g:compe

[hrqmonteiro]

I installed the plugin, and it ran the install.sh script.

But when i try to set it on my configs, i got this error when i open nvim.

[tzachar]

Make sure you call the compe plugin b4 the tabnine one and also setup compe b4 configuring tabnin.

[tzachar]

Also, the error you report looks like to be coming from within you own configuration. So unless you share something there's not much I can do to help u.

Compe is called before compe-tabnine:

And i am calling the line on the last line of my compe.lua file on purpose now so the compe setup is done before it:

local protocol = require "vim.lsp.protocol"
vim.o.completeopt = "menuone,noselect"
local remap = vim.api.nvim_set_keymap
local npairs = require('nvim-autopairs')
local exec = vim.api.nvim_exec

require "compe".setup {
  enabled = true,
  debug = false,
  min_length = 1,
  preselect = "disable",
  source_timeout = 200,
  -- incomplete_delay = 400,
  allow_prefix_unmatch = false,
  documentation = true,
  source = {
    path = {menu = ""},
    buffer = {menu = ""},
    vsnip = {menu = ""},
    nvim_lsp = {menu = ""},
    nvim_lua = {menu = ""},
    treesitter = {menu = "滑"},
    spell = true,
    calc = true,
    tags = true
    -- omni = true
  }
}

local t = function(str)
  return vim.api.nvim_replace_termcodes(str, true, true, true)
end

local check_back_space = function()
  local col = vim.fn.col(".") - 1
  if col == 0 or vim.fn.getline("."):sub(col, col):match("%s") then
    return true
  else
    return false
  end
end

-- Use (s-)tab to:
--- move to prev/next item in completion menuone
--- jump to prev/next snippet's placeholder
_G.tab_complete = function()
  if vim.fn.pumvisible() == 1 then
    return t "<C-n>"
  elseif vim.fn.call("vsnip#available", {1}) == 1 then
    return t "<Plug>(vsnip-expand-or-jump)"
  elseif check_back_space() then
    return t "<Tab>"
  else
    return vim.fn['compe#complete']()
  end
end
_G.s_tab_complete = function()
  if vim.fn.pumvisible() == 1 then
    return t "<C-p>"
  elseif vim.fn.call("vsnip#jumpable", {-1}) == 1 then
    return t "<Plug>(vsnip-jump-prev)"
  else
    return t "<S-Tab>"
  end
end

_G.MUtils= {}
vim.g.completion_confirm_key = ""
MUtils.completion_confirm=function()
  if vim.fn.pumvisible() ~= 0  then
    if vim.fn.complete_info()["selected"] ~= -1 then
      vim.fn["compe#confirm"]()
      return npairs.esc("<c-y>")
    else
      vim.defer_fn(function()
        vim.fn["compe#confirm"]("<cr>")
      end, 20)
      return npairs.esc("<c-n>")
    end
  else
    return npairs.check_break_line_char()
  end
end

remap('i' , '<CR>','v:lua.MUtils.completion_confirm()', {expr = true , noremap = true})
remap("i", "<Tab>", "v:lua.tab_complete()", {expr = true})
remap("s", "<Tab>", "v:lua.tab_complete()", {expr = true})
remap("i", "<S-Tab>", "v:lua.s_tab_complete()", {expr = true})
remap("s", "<S-Tab>", "v:lua.s_tab_complete()", {expr = true})

exec(
[[
let g:compe.source.tabnine = v:true
]], "")

And it still causing the same error:

Also, the install.sh runs normally if i do it again:

$ ./.local/share/nvim/site/pack/paqs/start/compe-tabnine/install.sh
++ curl -sS https://update.tabnine.com/version
+ version=3.2.28
+ case $(uname -s) in

[tzachar]

you should initialize tabnine as ou do all the internal source:

require "compe".setup {
  enabled = true,
  debug = false,
  min_length = 1,
  preselect = "disable",
  source_timeout = 200,
  -- incomplete_delay = 400,
  allow_prefix_unmatch = false,
  documentation = true,
  source = {
    path = {menu = ""},
    buffer = {menu = ""},
    vsnip = {menu = ""},
    nvim_lsp = {menu = ""},
    nvim_lua = {menu = ""},
    treesitter = {menu = "滑"},
    spell = true,
    calc = true,
    tags = true,
    tabnine = true
  }
}

@tzachar I added tabnine = {kind = "", priority=200, max_num_results=3} to my config and TabNine never starts up. Here is my entire compe config.

local M = {}

M.config = function()
    require "compe".setup {
        enabled = true,
        autocomplete = true,
        debug = true,
        min_length = 1,
        preselect = "enable",
        throttle_time = 80,
        source_timeout = 200,
        incomplete_delay = 400,
        max_abbr_width = 100,
        max_kind_width = 100,
        max_menu_width = 100,
        documentation = true,
        source = {
          path = {kind = " "},
          buffer = {kind = "﬘", true},
          luasnip = {kind = " ", true},
          nvim_lsp = true,
          nvim_lua = true,
          tabnine = {kind = "", priority=200, max_num_results=3}
        }
    }
end

M.snippets = function()
    local ls = require("luasnip")

    ls.config.set_config(
        {
            history = true,
            updateevents = "TextChanged,TextChangedI"
        }
    )
    require("luasnip/loaders/from_vscode").load()
end

return M
