Copilot Extra

ai.copilot runs GitHub’s official copilot-language-server as a regular LSP server and shows its suggestions with Neovim’s native inline completion (:help lsp-inline_completion). No Copilot plugin is involved. It is never enabled by default.

Enable it

-- ~/.config/blak/lua/blak/user.lua
return {
  extras = {
    enabled = {
      "ai.copilot",
    },
  },
}

Or enable it from Neovim:

:BlakExtras enable ai.copilot

Mason installs copilot-language-server automatically. Mason’s launcher needs Node.js 22.13 or newer on PATH.

What it adds

Surface	Contribution
LSP	copilot server (config from nvim-lspconfig)
Mason	copilot-language-server
Inline completion	vim.lsp.inline_completion.enable()
Commands	:LspCopilotSignIn, :LspCopilotSignOut in attached buffers
Keymap	<M-l> in insert mode accepts the suggestion
Keymap	<M-]> / <M-[> in insert mode cycle suggestions

The keymaps appear in :BlakKeys. They do nothing when no suggestion is shown.

Sign in

Open any file, then run:

:LspCopilotSignIn

The command (from nvim-lspconfig) copies a one-time code to your clipboard and offers to open the GitHub device-login page. The server keeps credentials in $XDG_CONFIG_HOME/github-copilot/, the same store copilot.lua’s bundled server uses, so an existing copilot.lua sign-in carries over. Until you sign in, the server attaches but shows no suggestions; requests fail quietly with NotSignedIn in the LSP log. :checkhealth vim.lsp lists the copilot client and the log path.

Configure Copilot

Server settings go through lsp.servers.copilot. For example, nvim-lspconfig sends telemetry.telemetryLevel = "all" by default; lower it with:

return {
  extras = { enabled = { "ai.copilot" } },
  lsp = {
    servers = {
      copilot = {
        settings = { telemetry = { telemetryLevel = "off" } },
      },
    },
  },
}

To pause suggestions for a session:

:lua vim.lsp.inline_completion.enable(false)

Next Edit Suggestions

ai.sidekick uses this same Copilot server for Next Edit Suggestions. Enable both extras and set ai.sidekick.nes.enabled = true. See the Sidekick extra.

Disable it

:BlakExtras disable ai.copilot

Restart Blak to stop the server. copilot-language-server stays installed in Mason until you remove it with :Mason.
