nvim-tabline

A minimal Tabline plugin for Neovim, written in Lua. It is basically a drop-in replacement for tabline.vim but with a few differences.

Installation

With lazy.nvim:

{
    'crispgm/nvim-tabline',
    dependencies = { 'nvim-tree/nvim-web-devicons' }, -- optional
    config = true,
}

Configuration

require('tabline').setup({opts})

Defaults

require('tabline').setup({
    show_index = true,           -- show tab index
    show_modify = true,          -- show buffer modification indicator
    show_icon = false,           -- show file extension icon
    fnamemodify = ':t',          -- file name modifier string
                                 -- can be a function to modify buffer name
    modify_indicator = '[+]',    -- modify indicator
    no_name = 'No name',         -- no name buffer name
    brackets = { '[', ']' },     -- file name brackets surrounding
    inactive_tab_max_length = 0  -- max length of inactive tab titles, 0 to ignore
})

Show Tabline

" Only if there are at least two tabs (default)
vim.opt.showtabline = 1

" Always
vim.opt.showtabline = 2

" Never
vim.opt.showtabline = 0

Mappings

Vim's tabpage commands are powerful enough, :help tabpage for details. If you need switch between tabs, here is a great tutorial.

Highlights

The highlighting of the tab pages line follows vim settings. See :help setting-tabline for details.

Differences

nvim-tabline is not exactly a Lua translation. There are some differences for configuration:

• Control whether to display tab number (show_index) and buffer modification indicator (show_modify).
• File extension icon with nvim-dev-icons.
• Customize modify indicator and no name buffer name.
• Close button (g:tablineclosebutton) is not supported.
