tabbymacs

Tabbymacs is an Emacs minor mode that brings Tabby AI inline completions into your editor. It displays completions as ghost text, similar to GitHub Copilot, but is powered by Tabby - an open-source, self-hosted AI coding assistant.

Features

• Inline (ghost text) completions at point
• Automatic or manual triggering of completions
• Accept or dismiss suggestions with simple key bindings
• Suggestions disappear automatically when you keep typing
• Efficient incremental sync with tabby-agent via JSON-RPC
• Lightweight LSP client design with inline completion support (approach recommended by Tabby team)

Requirements

• Emacs 27.1+
• Tabby Server: The backend LLM server, please refer to this documentation
• Tabby Agent (LSP server): Requires Node.js version v18.0+ and tabby-agent installed (npm install --global tabby-agent)
  • Remember to configure Tabby Agent according to documentation

Installation

Manual

Clone this repo and add it to your load-path:

(add-to-list 'load-path "/path/to/tabbymacs")
(require 'tabbymacs)

Using use-package

;;Example configuration
(use-package tabbymacs
  :load-path "/path/to/tabbymacs"
  :init
  (setq tabbymacs-inline-completion-idle-time 0.6)
  (setq tabbymacs-log-level :debug)
  :hook (prog-mode . tabbymacs-mode))

Enable tabbymacs-mode in a buffer: M-x tabbymacs-mode.

If everything is working, ghost text suggestions will appear while you type.
