}

Usage​

After installation, please exit and restart Vim or NeoVim. Then you can check the Tabby plugin status by running :Tabby in your vim command line. If you see any message reported by Tabby, it means the plugin is installed successfully. If you see Not an editor command: Tabby or any other error message, please check the installation steps.

In insert mode, Tabby plugin will show inline completion automatically when you stop typing. You can simply press <Tab> to accept the completion. If you want to dismiss the completion manually, you can press <C-\> to dismiss, and press <C-\> again to show the completion again.

Configuration​

Tabby Server​

You need to start the Tabby server before using the plugin. For Tabby server installation, please refer to this documentation.

If your Tabby server endpoint is different from the default http://localhost:8080, please set the endpoint in ~/.tabby-client/agent/config.toml.

If your Tabby server requires an authentication token, remember to set it here.

# Server
# You can set the server endpoint here.
[server]
endpoint = "http://localhost:8080" # http or https URL
token = "your-auth-token"

Node.js Binary Path​

Normally, this config is not required as the Tabby plugin will try to find the Node.js binary in your PATH environment variable.
But if you have installed Node.js in a non-standard location, or you are using a Node.js version manager such as nvm, you can set the Node.js binary path in your vim config file (~/.vimrc for Vim and ~/.config/nvim/init.vim or ~/.config/nvim/init.lua for NeoVim).

let g:tabby_node_binary = '/path/to/node'
--- lua
vim.g.tabby_node_binary = '/path/to/node'

Completion Trigger Mode​

Completion trigger mode is set to auto by default, Tabby plugin will show inline completion automatically when you stop typing.
If you prefer to trigger code completion manually, add this config in your vim config file. Tabby plugin will not show inline completion automatically, you can trigger the completion manually by pressing <C-\>.

let g:tabby_trigger_mode = 'manual'
--- lua
vim.g.tabby_trigger_mode = 'manual'

KeyBindings​

The default key bindings for accept completion(<Tab>), manual trigger/dismiss(<C-\>) can be customized with the following global settings.

let g:tabby_keybinding_accept = '<Tab>'
let g:tabby_keybinding_trigger_or_dismiss = '<C-\>'
--- lua
vim.g.tabby_keybinding_accept = '<Tab>'
vim.g.tabby_keybinding_trigger_or_dismiss = '<C-\\>'

Known Conflicts​

  • For the default settings, Tabby will attempt to set up the <Tab> key mapping. If Tabby's inline completion is not displayed, it will fall back to the original mapping. However, this approach might not work when there is a conflict with other plugins that also map the <Tab> key, as they could overwrite Tabby's mapping. In such cases, you can use a different keybinding to accept the completion and avoid conflicts.

  • Tabby internally utilizes the <C-R><C-O> command to insert the completion. If you have mapped <C-R> to other functions, you won't be able to accept the completion. In such scenarios, you may need to manually modify the function tabby#Accept() in autoload/tabby.vim.
