Completions

Zed supports supports two sources for completions:

"Code Completions" provided by Language Servers (LSPs) automatically installed by Zed or via Zed Language Extensions.
"Inline Completions" provided by external APIs like GitHub Copilot or Supermaven.

Code Completions

When there is an appropriate language server available, Zed will by-default provide completions of variable names, functions, and other symbols in the current file. You can disable these by adding the following to your zed settings.json file:

"show_completions_on_input": false

You can manually trigger completions with ctrl-space or by triggering the editor::ShowCompletions action from the command palette.

Configuring Inline Completions

GitHub Copilot

To use GitHub Copilot (enabled by default), add the following to your settings.json:

{
  "features": {
    "inline_completion_provider": "copilot"
  }
}

You should be able to sign-in to GitHub Copilot by clicking on the Copilot icon in the status bar and following the setup instructions.

Supermaven

To use Supermaven, add the following to your settings.json:

{
  "features": {
    "inline_completion_provider": "supermaven"
  }
}

You should be able to sign-in to Supermaven by clicking on the Supermaven icon in the status bar and following the setup instructions.

Using Inline completions

Once you have configured an Inline Completions provider, you can start using inline completions in your code. Inline completions will appear as you type, and you can accept them by pressing tab or enter or hide them by pressing esc.

There a number of actions/shortcuts available to interact with inline completions:

editor: accept inline completion (tab): To accept the current inline completion
editor: accept partial inline completion (cmd-right): To accept the current inline completion up to the next word boundary
editor: show inline completion (alt-\\): Trigger a inline completion request manually
editor: next inline completion (alt-]): To cycle to the next inline completion
editor: previous inline completion (alt-[): To cycle to the previous inline completion

Disabling Inline-Completions

To disable completions that appear automatically as you type, add the following to your settings.json:

{
  "show_inline_completions": false
}

You can trigger inline completions manually by executing editor: show inline completion (alt-\\).

You can also add this as a language-specific setting in your settings.json to disable inline completions for a specific language:

{
  "language": {
    "python": {
      "show_inline_completions": false
    }
  }
}
