barbar.nvim

Tabs, as understood by any other editor.

barbar.nvim is a tabline plugin with re-orderable, auto-sizing, clickable tabs, icons, nice highlighting, sort-by commands and a magic jump-to-buffer mode. Plus the tab names are made unique when two filenames match.

In jump-to-buffer mode, tabs display a target letter instead of their icon. Jump to any buffer by simply typing their target letter. Even better, the target letter stays constant for the lifetime of the buffer, so if you're working with a set of files you can even type the letter ahead from memory.

Install

Requirements:

• Neovim v0.7+

Optional Requirements:

• File icons: nvim-web-devicons
  • NOTE: Requires a nerd font by default. Can be configured to remove this requirement.
• Git integration: gitsigns.nvim

Using lazy.nvim

require('lazy').setup {
  {'romgrk/barbar.nvim',
    dependencies = {
      'lewis6991/gitsigns.nvim', -- OPTIONAL: for git status
      'nvim-tree/nvim-web-devicons', -- OPTIONAL: for file icons
    },
    init = function() vim.g.barbar_auto_setup = false end,
    opts = {
      -- lazy.nvim will automatically call setup for you. put your options here, anything missing will use the default:
      -- animation = true,
      -- insert_at_start = true,
      -- …etc.
    },
    version = '^1.0.0', -- optional: only update when a new 1.x version is released
  },
}

Using packer.nvim

-- These optional plugins should be loaded directly because of a bug in Packer lazy loading
use 'nvim-tree/nvim-web-devicons' -- OPTIONAL: for file icons
use 'lewis6991/gitsigns.nvim' -- OPTIONAL: for git status
use 'romgrk/barbar.nvim'

Using vim-plug

Plug 'nvim-tree/nvim-web-devicons' " OPTIONAL: for file icons
Plug 'lewis6991/gitsigns.nvim' " OPTIONAL: for git status
Plug 'romgrk/barbar.nvim'

Features

Re-order tabs

Auto-sizing tabs, fill the space when available

Jump-to-buffer mode

Type a letter to jump to a buffer. Letters stay constant for the lifetime of the buffer. By default, letters are assigned based on buffer name, eg README.md will get letter r. You can change this so that letters are assigned based on usability: home row (asdfjkl;gh) first, then other rows.

Sort tabs automatically

:BufferOrderByName, :BufferOrderByDirectory, :BufferOrderByLanguage, :BufferOrderByWindowNumber, :BufferOrderByBufferNumber

Clickable & closable tabs

Left-click to go, middle-click or close button to close. Don't forget to set mouse+=a.

Unique names when filenames match

Pinned buffers

bbye.vim for closing buffers

A modified version of bbye.vim is included in this plugin to close buffers without messing with your window layout and more. Available as BufferClose and bufferline#bbye#delete(buf).

Scrollable tabs, to always show the current buffer

Offset bufferline when showing sidebars

Usage

Mappings & commands

Vim script

No default mappings are provided, here is an example. It is recommended to use the BufferClose command to close buffers instead of bdelete because it will not mess your window layout.

Note

In the below key mappings, the Alt key is being used. If you are using a terminal like iTerm on Mac, you will want to make sure that your Option key is properly mapped to Alt. Its under Profiles > Keys, select Esc+

Highlighting

Highlight groups are created in this way: Buffer<STATUS><PART>.

<STATUS>	Meaning
Alternate	The :h alternate-file.
Current	The current buffer.
Inactive	:h hidden-buffers and :h inactive-buffers.
Visible	:h active-buffers which are not alternate or current.

<PART>	Meaning
ADDED	Git status added.
Btn	The button that shows when a buffer is unpinned and unmodified.
CHANGED	Git status changed.
DELETED	Git status deleted.
ERROR	Diagnostic errors.
HINT	Diagnostic hints.
Icon	The filetype icon (when icons.filetype == {custom_colors = true, enabled = true}).
Index	The buffer's position in the tabline.
INFO	Diagnostic info.
Mod	When the buffer is modified.
ModBtn	The button that shows when a buffer is modified.
Number	The :h bufnr().
Pin	When the buffer is pinned.
PinBtn	The button that shows when a buffer is pinned.
Sign	The separator between buffers.
SignRight	The separator between buffers.
Target	The letter in buffer-pick mode.
WARN	Diagnostic warnings.

• e.g. the current buffer's highlight when modified is BufferCurrentMod

There are a few highlight groups which do not follow this rule. They are:

Group	Usage
BufferOffset	The background of the header for a sidebar_filetype
BufferScrollArrow	The arrow which shows to indicate that there are more buffers to the left or right of the scroll position.
BufferTabpageFill	The space between the open buffer list and the tabpage
BufferTabpages	The color of the tabpages indicator.
BufferTabpagesSep	The separator between the tabpages count.

You can also use the doom-one.vim colorscheme that defines those groups and is also very pleasant as you could see in the demos above.

Integrations

scope.nvim

To preserve buffer order while using scope.nvim, you can add this to your config:

require('scope').setup {
  hooks = {
    pre_tab_leave = function()
      vim.api.nvim_exec_autocmds('User', {pattern = 'ScopeTabLeavePre'})
      -- [other statements]
    end,

    post_tab_enter = function()
      vim.api.nvim_exec_autocmds('User', {pattern = 'ScopeTabEnterPost'})
      -- [other statements]
    end,

    -- [other hooks]
  },

  -- [other options]
}

Sessions

barbar.nvim can restore the order that your buffers were in, as well as whether a buffer was pinned. To do this, sessionoptions must contain globals, and the User SessionSavePre event must be executed before :mksession.

mini.nvim

Here is a mini.sessions config which can be used:

vim.opt.sessionoptions:append 'globals'
require'mini.sessions'.setup {
  hooks = {
    pre = {
      write = function() vim.api.nvim_exec_autocmds('User', {pattern = 'SessionSavePre'}) end,
    },
  },
}

persistence.nvim

Here is a persistence.nvim config which can be used:

require'persistence'.setup {
  options = {--[[<other options>,]] 'globals'},
  pre_save = function() vim.api.nvim_exec_autocmds('User', {pattern = 'SessionSavePre'}) end,
}

persisted.nvim

Here is a persisted.nvim config which can be used:

vim.opt.sessionoptions:append 'globals'
vim.api.nvim_create_autocmd({ 'User' }, {
  pattern = 'PersistedSavePre',
  group = vim.api.nvim_create_augroup('PersistedHooks', {}),
  callback = function()
    vim.api.nvim_exec_autocmds('User', { pattern = 'SessionSavePre' })
  end,
})

resession.nvim

This plugin comes with support for resession.nvim through an extension. To enable, add the following snippet to your resession config:

extensions = {
  barbar = {},
}

If using lazy.nvim then ensure you add barbar.nvim as a dependency to resession, to ensure that the extension loads before resession.

Custom

You can add this snippet to your config to take advantage of our session integration:

vim.opt.sessionoptions:append 'globals'
vim.api.nvim_create_user_command(
  'Mksession',
  function(attr)
    vim.api.nvim_exec_autocmds('User', {pattern = 'SessionSavePre'})

    -- Neovim 0.8+
    vim.cmd.mksession {bang = attr.bang, args = attr.fargs}

    -- Neovim 0.7
    vim.api.nvim_command('mksession ' .. (attr.bang and '!' or '') .. attr.args)
  end,
  {bang = true, complete = 'file', desc = 'Save barbar with :mksession', nargs = '?'}
)

Known Issues

Lightline

Barbar doesn't show up because lightline changes the tabline setting. Add:

let g:lightline={ 'enable': {'statusline': 1, 'tabline': 0} }

Netrw

netrw has a lot of bugs which make it hard to support. It may work partially, but we will not make changes to barbar.nvim to work-around netrw-specific bugs (e.g. #82).

You can use any other file explorer instead.

Sidebars On Startup

The sidebar_filetypes option may not work as expected if your sidebar opens on startup. See nvim-tree/nvim-tree.lua#2130 for details, and #421 for a workaround.

About

Barbar is called barbar because it's a bar, but it's also more than a bar: a "barbar".

It is pronounced like "Jar Jar" in "Jar Jar Binks", but with Bs.

No, barbar has nothing to do with barbarians.
