How to make autocomplete manually triggered?

[brokenthorn]

Whenever I am writing code but most often happens with comments, there are situations where the autocomplete popup shows up with some match, and while writing the comment or code in the speed of it, NvChad totally messes up what I am trying to write, as it is either inserting a huge snippet or overwriting the word I am trying to write with something else, and all I'm doing is just simply writing.

I am not looking to disable the autocomplete popup, as I find it useful to see suggestions, but I want to have to press TAB first to actually select into it an item that I want to autocomplete, and then press Enter like usual to activate the completion, but I do not want the completion to ever activate by itself.

I have been looking into this but I am quite new to using nvim, just a few months. I believe it's the cmp plugin that I need to configure, and I need to disable the preselection to be None, as referenced here: hrsh7th/nvim-cmp#1411 but I am not sure how to configure cmp correctly with NvChad.

Can anyone help and is there any chance that this might become the default configuration? It's practically the default with most other editors.

Thanks!

#2193 - completely disables autocomplete popup and you have to press Ctrl-Space to trigger it, which I do not want. Two less keys to press this way.
#1667 - is also not what I want and the solutions proposed there are not very idiomatic.

I seem to have found the solution, which is what is proposed in #2193, except it does not disable the popup like it says in the ticket, but only disables cmp from automatically performing completion with the first item (which it used to automatically select) when pressing space, which is exactly what I wanted!

local plugins = {
  -- other plugins...
  {
    "hrsh7th/nvim-cmp",
    opts = {
      completion = {
        autocomplete = false,
      },
    },
  },
  -- other plugins...
}

Correction, that did not fix it. Here is a demo:

I think there might be two fixes: either change the autocomplete key, or disable preselecting of the first item.

I would prefer the second, as I like to be able to trigger with Enter.

@brokenthorn there's an option for the 2nd one, google up & read cmp docs, and seek help in our discord server as its more active than here

Finally did it!

  {
    "hrsh7th/nvim-cmp",
    opts = {
      mapping = {
        ["<CR>"] = cmp.mapping.confirm {
          behavior = cmp.ConfirmBehavior.Insert,
          -- when true, auto-selects the first item if nothing was selected,
          -- making noselect below not take effect.
          select = false,
        },
      },
      -- adding noselect compared to default, to prevent autocomplete when typing,
      -- and this is actually nvim-cmp defaults, but NvChad overrides this.
      completion = {
        completeopt = "menu,menuone,noselect",
      },
      -- for LSPs that (re)enable this:
      preselect = cmp.PreselectMode.None,
    },
  },

@brokenthorn opts does merge, but the thing is that you ran cmp module directly, which will break lazyloading of cmp, so we better wrap it in a function!

[brokenthorn]

I'm not sure where I was running it directly or what that means. Please can you explain?

[brokenthorn]

@brokenthorn your method removes all of lazyloading of cmp by calling its module directly into opts table, instead of that we make opts a function

  {
    "hrsh7th/nvim-cmp",
    opts = function()
      local config = require "plugins.configs.cmp"
      local cmp = require "cmp"

      config.mapping["<CR>"] = cmp.mapping.confirm {
        behavior = cmp.ConfirmBehavior.Insert,
        select = false,
      }

      config.completion = {
        completeopt = "menu,menuone,noselect",
      }

      config.preselect = cmp.PreselectMode.None

      return config
    end,
  }

Worked perfectly. Thank you.

[siduck]

yes you ran it directly, if a module is exposed outside a function then nvim automatically executes it, but if you wrap it in a function then nvim doesnt execute it by default, it executes it when the function call happens

Works for me too!
