Tabby Agent

The tabby-agent is an agent used for communication with the Tabby server. It is based on Node.js v18 and runs as a language server.

Breaking Changes: The tabby-agent will only support running as a language server since version 1.7.0.

The tabby-agent mainly supports the following features of LSP:

• Completion (textDocument/completion)
• Inline Completion (textDocument/inlineCompletion, since LSP v3.18.0)

For collecting more context to enhance the completion quality or providing more features like inline chat editing, the tabby-agent extends the protocol with some custom methods starting with tabby/*. These methods are used in Tabby-provided editor extensions.

Usage

Note: For VSCode, IntelliJ Platform IDEs, and Vim/NeoVim, it is recommended to use the Tabby-provided extensions, which run the Tabby Agent underlying.

• VSCode
• IntelliJ Platform IDEs
• Vim/NeoVim

The following guide is only for users who want to set up the tabby-agent as a language server manually.

Start the Language Server

npx tabby-agent --stdio

Connect the IDE to the tabby-agent

Since most text editors have their built-in LSP clients or popular LSP client plugins, you can easily connect to the tabby-agent from your editor. Here are some example configurations for popular editors.

Vim/Neovim (coc.nvim)

There are several Vim plugins that provide LSP support. One of them is coc.nvim. To use the tabby-agent as a language server, you can add the following code to your :CocConfig.

{
  "languageserver": {
    "tabby-agent": {
      "command": "npx",
      "args": ["tabby-agent", "--stdio"],
      "filetypes": ["*"]
    }
  }
}

Emacs

The package lsp-mode provides an LSP client for Emacs. You can add the following code to your Emacs configuration script to use the tabby-agent as a language server.

(with-eval-after-load 'lsp-mode
  (lsp-register-client
    (make-lsp-client  :new-connection (lsp-stdio-connection '("npx" "tabby-agent" "--stdio"))
                      ;; you can select languages to enable Tabby language server
                      :activation-fn (lsp-activate-on "typescript" "javascript" "toml")
                      :priority 1
                      :add-on? t
                      :server-id 'tabby-agent)))

Helix

Helix has built-in LSP support. To use the tabby-agent as a language server, you can add the following code to your languages.toml.

[language-server.tabby]
command = "npx"
args = ["tabby-agent", "--stdio"]

# Add Tabby as the second language server for your specific languages
[[languages]]
name = "typescript"
language-servers = ["typescript-language-server", "tabby"]

[[languages]]
name = "toml"
language-servers = ["taplo", "tabby"]
