toggleterm.nvim

A neovim plugin to persist and toggle multiple terminals during an editing session

Multiple orientations

• Float

• Vertical

• Tab

Send commands to different terminals

Winbar (Experimental/Nightly ONLY)

Requirements

This plugin only works in Neovim 0.7 or newer.

Installation

Using packer in lua

use {"akinsho/toggleterm.nvim", tag = '*', config = function()
  require("toggleterm").setup()
end}

Using vim-plug in vimscript

Plug 'akinsho/toggleterm.nvim', {'tag' : '*'}

You can/should specify a tag for the current major version of the plugin, to avoid breaking changes as this plugin evolves. To use a version of this plugin compatible with nvim versions less than 0.7 please use the tag v1.*.

Notices

• 28/07/1990 — If using persist_mode terminal mappings should be changed to use wincmd instead otherwise persist mode will not work correctly. See here for details.

Why?

Neovim's terminal is a very cool, but not super ergonomic tool to use. I find that I often want to set a process going and leave it to continue to run in the background. I don't need to see it all the time. I just need to be able to refer back to it at intervals. I also sometimes want to create a new terminal and run a few commands.

Sometimes I want these side by side, and I really want these terminals to be easy to access. I also want my terminal to look different from non-terminal buffers, so I use winhighlight to darken them based on the Normal background colour.

This is the exact use case this was designed for. If that's your use case this might work for you.

Roadmap

All I really want this plugin to be is what I described above. A wrapper around the terminal functionality.

It basically (almost) does all that I need it to.

I won't be turning this into a REPL plugin or doing a bunch of complex stuff. If you find any issues, please consider a pull request not an issue. I'm also going to be pretty conservative about what I add.

Setup

This plugin must be explicitly enabled by using require("toggleterm").setup{}

Setting the open_mapping key to use for toggling the terminal(s) will set up mappings for normal mode If you prefix the mapping with a number that particular terminal will be opened.

If you set the insert_mappings key to true, the mapping will also take effect in insert mode; similarly setting terminal_mappings to will have the mappings take effect in the opened terminal.

However you will not be able to use a count with the open mapping in terminal and insert modes. You can create buffer specific mappings to exit terminal mode and then use a count with the open mapping. Check Terminal window mappings for an example of how to do this.

alternatively you can do this manually (not recommended but, your prerogative)

" set
autocmd TermEnter term://*toggleterm#*
      \ tnoremap <silent><c-t> <Cmd>exe v:count1 . "ToggleTerm"<CR>

" By applying the mappings this way you can pass a count to your
" mapping to open a specific window.
" For example: 2<C-t> will open terminal 2
nnoremap <silent><c-t> <Cmd>exe v:count1 . "ToggleTerm"<CR>
inoremap <silent><c-t> <Esc><Cmd>exe v:count1 . "ToggleTerm"<CR>

NOTE: Please ensure you have set hidden in your neovim config, otherwise the terminals will be discarded when closed.

Usage

ToggleTerm

This is the command the mappings call under the hood. You can use it directly and prefix it with a count to target a specific terminal. This function also takes arguments size, dir and direction. e.g.

:ToggleTerm size=40 dir=~/Desktop direction=horizontal

If dir is specified on creation toggle term will open at the specified directory. If the terminal has already been opened at a particular directory it will remain in that directory.

The directory can also be specified as git_dir which toggleterm will then use to try and derive the git repo directory. NOTE: This will not work for git-worktrees or other more complex setups.

If size is specified, and the command opens a split (horizontal/vertical) terminal, the height/width of all terminals in the same direction will be changed to size.

If direction is specified, and the command opens a terminal, the terminal will be changed to the specified direction.

size and direction are ignored if the command closes a terminal.

Caveats

• Having multiple terminals with different directions open at the same time is unsupported.

ToggleTermToggleAll

This command allows you to open all the previously toggled terminal in one go or close all the open terminals at once.

TermExec

This command allows you to open a terminal with a specific action. e.g. 2TermExec cmd="git status" dir=~/<my-repo-path> will run git status in terminal 2. note that the cmd argument must be quoted.

NOTE: the dir argument can also be optionally quoted if it contains spaces.

The cmd and dir arguments can also expand the same special keywords as :h expand e.g. TermExec cmd="echo %" will be expanded to TermExec cmd="echo /file/example"

These special keywords can be escaped using the \ character, if you want to print character as is.

The size and direction arguments are like the size and direction arguments of ToggleTerm.

By default, focus is returned to the original window after executing the command (except for floating terminals). Use argument go_back=0 to disable this behaviour.

You can send commands to a terminal without opening its window by using the open=0 argument.

see :h expand() for more details

Sending lines to the terminal

You can "send lines" to the toggled terminals with the following commands:

• :ToggleTermSendCurrentLine <T_ID>: sends the whole line where you are standing with your cursor
• :ToggleTermSendVisualLines <T_ID>: sends all the (whole) lines in your visual selection
• :ToggleTermSendVisualSelection <T_ID>: sends only the visually selected text (this can be a block of text or a selection in a single line)

(<T_ID is an optional terminal ID parameter, which defines where should we send the lines. If the parameter is not provided, then the default is the first terminal)

Example:

send_lines_example.mov

ToggleTermSetName

This function allows setting a display name for a terminal. This name is primarily used inside the winbar, and can be a more descriptive way to remember, which terminal is for what.

You can map this to a key and call it with a count, which will then prompt you a name for the terminal with the matching ID. Alternatively you can call it with just the name e.g. :ToggleTermSetName work<CR> this will the prompt you for which terminal it should apply to. Lastly you can call it without any arguments, and it will prompt you for which terminal it should apply to then prompt you for the name to use.

Set terminal shading

This plugin automatically shades terminal filetypes to be darker than other window you can disable this by setting shade_terminals = false in the setup object

require'toggleterm'.setup {
  shade_terminals = false
}

alternatively you can set, which filetypes should be shaded by setting

-- fzf is just an example
require'toggleterm'.setup {
  shade_filetypes = { "none", "fzf" }
}

setting "none" will allow normal terminal buffers to be highlighted.

Set persistent size

By default, this plugin will persist the size of horizontal and vertical terminals. Split terminals in the same direction always have the same size. You can disable this behaviour by setting persist_size = false in the setup object. Disabling this behaviour forces the opening terminal size to the size defined in the setup object.

require'toggleterm'.setup{
  persist_size = false
}

Terminal window mappings

It can be helpful to add mappings to make moving in and out of a terminal easier once toggled, whilst still keeping it open.

function _G.set_terminal_keymaps()
  local opts = {buffer = 0}
  vim.keymap.set('t', '<esc>', [[<C-\><C-n>]], opts)
  vim.keymap.set('t', 'jk', [[<C-\><C-n>]], opts)
  vim.keymap.set('t', '<C-h>', [[<Cmd>wincmd h<CR>]], opts)
  vim.keymap.set('t', '<C-j>', [[<Cmd>wincmd j<CR>]], opts)
  vim.keymap.set('t', '<C-k>', [[<Cmd>wincmd k<CR>]], opts)
  vim.keymap.set('t', '<C-l>', [[<Cmd>wincmd l<CR>]], opts)
end

-- if you only want these mappings for toggle term use term://*toggleterm#* instead
vim.cmd('autocmd! TermOpen term://* lua set_terminal_keymaps()')

Custom Terminals

using lazygit

Toggleterm also exposes the Terminal class so that this can be used to create custom terminals for showing terminal UIs like lazygit, htop etc.

Each terminal can take the following arguments:

Terminal:new {
  cmd = string -- command to execute when creating the terminal e.g. 'top'
  direction = string -- the layout for the terminal, same as the main config options
  dir = string -- the directory for the terminal
  close_on_exit = bool -- close the terminal window when the process exits
  highlights = table -- a table with highlights
  env = table -- key:value table with environmental variables passed to jobstart()
  clear_env = bool -- use only environmental variables from `env`, passed to jobstart()
  on_open = fun(t: Terminal) -- function to run when the terminal opens
  on_close = fun(t: Terminal) -- function to run when the terminal closes
  auto_scroll = boolean -- automatically scroll to the bottom on terminal output
  -- callbacks for processing the output
  on_stdout = fun(t: Terminal, job: number, data: string[], name: string) -- callback for processing output on stdout
  on_stderr = fun(t: Terminal, job: number, data: string[], name: string) -- callback for processing output on stderr
  on_exit = fun(t: Terminal, job: number, exit_code: number, name: string) -- function to run when terminal process exits
}

Custom terminal usage

local Terminal  = require('toggleterm.terminal').Terminal
local lazygit = Terminal:new({ cmd = "lazygit", hidden = true })

function _lazygit_toggle()
  lazygit:toggle()
end

vim.api.nvim_set_keymap("n", "<leader>g", "<cmd>lua _lazygit_toggle()<CR>", {noremap = true, silent = true})

This will create a new terminal, but the specified command is not being run immediately. The command will run once the terminal is opened. Alternatively term:spawn() can be used to start the command in a background buffer without opening a terminal window yet. If the hidden key is set to true, this terminal will not be toggled by normal toggleterm commands such as :ToggleTerm or the open mapping. It will only open and close by using the returned terminal object. A mapping for toggling the terminal can be set as in the example above.

Alternatively the terminal can be specified with a count, which is the number that can be used to trigger this specific terminal. This can then be triggered using the current count e.g. :5ToggleTerm<CR>

local lazygit = Terminal:new({ cmd = "lazygit", count = 5 })

You can also set a custom layout for a terminal.

local lazygit = Terminal:new({
  cmd = "lazygit",
  dir = "git_dir",
  direction = "float",
  float_opts = {
    border = "double",
  },
  -- function to run on opening the terminal
  on_open = function(term)
    vim.cmd("startinsert!")
    vim.api.nvim_buf_set_keymap(term.bufnr, "n", "q", "<cmd>close<CR>", {noremap = true, silent = true})
  end,
  -- function to run on closing the terminal
  on_close = function(term)
    vim.cmd("startinsert!")
  end,
})

function _lazygit_toggle()
  lazygit:toggle()
end

vim.api.nvim_set_keymap("n", "<leader>g", "<cmd>lua _lazygit_toggle()<CR>", {noremap = true, silent = true})

WARNING: do not use any of the private functionality of the terminal or other non-public parts of the API as these can change in the future.

Statusline

To tell each terminal apart you can use the terminal buffer variable b:toggle_number in your statusline

" this is pseudo code
let statusline .= '%{&ft == "toggleterm" ? "terminal (".b:toggle_number.")" : ""}'

Custom commands

You can create your on commands by using the lua functions this plugin provides directly

command! -count=1 TermGitPush  lua require'toggleterm'.exec("git push",    <count>, 12)
command! -count=1 TermGitPushF lua require'toggleterm'.exec("git push -f", <count>, 12)

Open multiple terminals side-by-side

Direction	Supported
vertical	✔️
horizontal	✔️
tab	✖️
float	✖️

In your first terminal, you need to leave the TERMINAL mode using C-\C-N which can be remapped to Esc for ease of use.

Then you type on: 2<C-\>, and the result:

Explain:

• 2: this is the terminal's number (or ID), your first terminal is 1 (e.g. your 3rd terminal will be 3<C-\>, so on).
• C-\: this is the combined key mapping to the command :ToggleTerm.
