Full code snippet appears on nvim-cmp window but I can only accept the first line

[Vinni-Cedraz]

EDIT: I SOLVED IT AND IT WAS REALLY DUMB : I just figured it out when posting the cmd.lua configs here. There is a specific key to accept the suggestion entry and only when that key is pressed the entire suggestion is accepted, otherwise just the first line is inserted.

This is a different issue than the similar one we have there. That guy was having only the first line of code appearing in the nvim-cmp window. In my case the code appears entirely and without any issues in the window:

But pressing tab to accept it only writes out the first line on the file:

Here are my relevant configurations:

on plugins.lua (file where I install plugins using packer):

    use({
        "zbirenbaum/copilot.lua",
        event = { "vimenter" },
        config = function()
            vim.defer_fn(function()
                require("user.copilot").setup()
            end, 100)
        end,
    })

    -- copilot integration with nvim-cmp
    use({
        "zbirenbaum/copilot-cmp",
        after = { "copilot.lua" },
        config = function()
            require("copilot_cmp").setup({
                method = "getcompletionscycling",
            })
        end,
    })

on my copilot.lua file (config file required by init.lua where I configure the copilot.lua plugin):

local M = {}

function M.setup()
    require("copilot").setup({
        filetypes = { "lua", "c", "javascript", "typescript", "rust", "python" },
        suggestion = { enabled = false},
        panel = { enabled = false },
        plugin_manager_path = vim.call("stdpath", "data"),
    })
end

return M

cmp.lua (configuration file for nvim-cmp):

local cmp_status_ok, cmp = pcall(require, "cmp")
if not cmp_status_ok then
    return
end

-- Define a highlight group for the Copilot icon
vim.cmd('highlight MyCopilotIcon guifg=#ffa500')

local check_backspace = function()
    local col = vim.fn.col(".") - 1
    return col == 0 or vim.fn.getline("."):sub(col, col):match("%s")
end

That's all folks.

Since this is resolved I'm going to close it, glad you got it figured out!
