Is it possible to use tab normally when suggestions aren't shown and to accept suggestions when they are?

[Roundlay]

copilot.vim allows me to use tab for both accepting Copilot suggestions when they're visible, and for increasing the indentation level of the cursor as per normal when Copilot suggestions aren't visible. Is there a way to achieve the same functionality with copilot.lua?

[Roundlay]

Strangely enough, binding accept to "<C-i>" lets me use tab for both normal indentation and for accepting Copilot suggestions whenever they're visible, but this doesn't seem to work for other keybindings. Is this expected behaviour? Couldn't find anything about this in the help docs.

You can have super-tab like behavior, e.g.: https://github.com/MunifTanjim/dotfiles/blob/6b5199346f7e96065d5e517e61e2d8768e10770d/private_dot_config/nvim/lua/plugins/cmp.lua#L48-L63

For example:

vim.keymap.set('i', '<Tab>', function()
  if require("copilot.suggestion").is_visible() then
    require("copilot.suggestion").accept()
  else
    vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("<Tab>", true, false, true), "n", false)
  end
end, { desc = "Super Tab" })

Thank you 🙏

Hi! Thanks for the suggestion! Where would you write those lines? I'm not sure if they should be inside a mapping overwrite or inside the copilot.lua config

[MunifTanjim]

Disable the default accept keymap by doing:

require("copilot").setup({
  -- other options
  suggestion = {
    -- other options
    keymap = {
      -- other keymaps
      accept = false
    }
  }
})

Then add your custom accept keymap anywhere in your config. You can add it right below your require("copilot").setup call.

Hey @MunifTanjim I did this, but it still doesn't work can you please help

return {
  {
    "zbirenbaum/copilot.lua",
    cmd = "Copilot",
    event = "InsertEnter",
    config = function()
      require("copilot").setup({ suggestion = { auto_trigger = true, keymap = { accept = false } } })
      vim.keymap.set("i", "<Tab>", function()
        if require("copilot.suggestion").is_visible() then
          require("copilot.suggestion").accept()
        else
          vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("<Tab>", true, false, true), "n", false)
        end
      end, { desc = "Super Tab" })
    end,
  },
}

What's the output for :imap <Tab>?

[mikkybang]

Here:
i <Tab> * <Lua 529: ~/.local/share/nvim/lazy/LazyVim/lua/lazyvim/plugins/coding.lua:23>

LazyVim is overriding your keymap.

$XDG_CONFIG_HOME/nvim/lua/plugins/copilot.lua:

return {
  {
    "zbirenbaum/copilot.lua",
    cmd = "Copilot",
    event = "InsertEnter",
    opts = {
      panel = { enabled = false },
      keymap = { accept = false },
      auto_refresh = true,
      filetypes = {
        yaml = true,
        markdown = true,
        suggestion = { auto_trigger = true },
      },
      vim.keymap.set("i", "<Tab>", function()
        if require("copilot.suggestion").is_visible() then
          require("copilot.suggestion").accept()
        else
          vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("<Tab>", true, false, true), "n", false)
        end
      end, { desc = "Tab for copilot" }),
    },
  },
}

:imap <Tab> shows "Tab for copilot". But still, I cannot accept using Tab. Any ideas?

Your help is much appreciated.
