spywhere/tmux.nvim

neovim plugin for turning neovim into terminal multiplexer

tmux.nvim

This plugin still under development

This plugin provides a framework to turns Neovim into terminal multiplexer (heavily based on tmux)

The intention of this plugin is to eliminate the need of tmux for a basic terminal multiplexing feature by leveraging Neovim split and tab features

For those who's on Windows, this could be a workaround for lack of tmux but only for terminal multiplexing

Features

This are non exhaustive list of features available

• Panes
• Windows
• Status bar¹
• Copy mode¹
• (Detachable) Sessions²

1: Partially implemented
2: This requires Neovim to implement a server / client architecture which planned in neovim#10071

Getting Started

To quickly setup and run the first session of tmux.nvim

curl -fLo ~/.tmux.nvim/init.lua --create-dirs https://raw.githubusercontent.com/spywhere/tmux.nvim/main/tests/git.lua
nvim -u ~/.tmux.nvim/init.lua

This will download a basic configuration to ~/.tmux.nvim/init.lua and run it. In which, it will automatically install and setup the plugin using vim-plug.

Configurations

As the plugin still under development, please find the default configurations from following locations...

• Neovim configurations: lua/tmux/config.lua
• Status bar (built using tabline): lua/tmux/statusbar.lua
• Key bindings: lua/tmux/bindings.lua
• Available commands: lua/tmux/commands.lua

Please note that some options are opinionated and will be updated to match tmux's defaults later on

Installation

Requires neovim v0.7.0 or later.

If you wish to use tmux.nvim with older neovim version (v0.5.0 up to v0.6.1), check out nvim-0.5.0 branch. Do note that nvim-0.5.0 branch is for migration purpose only so the code will not be maintained.

It is highly recommended to clone the repository (or download a zip file) and place it somewhere (~/.tmux.nvim would work too)

git clone https://github.com/spywhere/tmux.nvim ~/.tmux.nvim

or install using a plugin manager of your choice, for example:

Plug 'spywhere/tmux.nvim'

Integration

Create a file named init.lua and place it somewhere (in this example, ~/.tmux.nvim/init.lua will be used)

-- if you're cloning the repository, you will need to add the plugin directory
--   to the 'runtimepath'
vim.opt.rtp:append('~/.tmux.nvim')

local tmux = require('tmux')
local cmds = require('tmux.commands')

-- some configurations go here

-- may be changing the default prefix key?
--   tmux.prefix('<C-a>')

-- may be binding a new key?
--   tmux.bind('|', cmds.split_window { 'v' } )
--   tmux.bind('-', cmds.split_window { 'h' } )

tmux.start() -- this will start a terminal session

then, when you're ready to use Neovim as terminal multiplexer, just run

nvim -u ~/.tmux.nvim/init.lua

Check out bindings.lua for how tmux.nvim set a default key bindings

Supported Features

These are a list of features that required a certain version of Neovim

Neovim 0.8 or later is required for

• Cleaner status line (hide the command line)

Neovim 0.7 or later is required for

• Status line on the bottom (above command line)

Neovim 0.5 or later is required for

• Basic functionality

Contributes

During the development, you can use the following command to automatically setup a working configurations to test the plugin...

or

nvim -u tests/init.lua

Alternatively, if you wish to test the plugin through direct cloning, use...

make testrun-from-git

or

nvim -u tests/git.lua
