## Performance compared to other plugins

Unlike other statusline plugins, lualine loads only the components you specify, and nothing else.

Startup time performance measured with an amazing plugin [dstein64/vim-startuptime](https://github.com/dstein64/vim-startuptime)

Times are measured with a clean `init.vim` with only `vim-startuptime`,
`vim-plug` and given statusline plugin installed.
In control just `vim-startuptime` and`vim-plug` is installed.
And measured time is complete startuptime of vim not time spent
on specific plugin. These numbers are the average of 20 runs.

| control | lualine | lightline | airline |
| :-----: | :-----: | :-------: | :-----: |
| 17.2 ms | 24.8 ms |  25.5 ms  | 79.9 ms |

Last Updated On: 18-04-2022

## Installation

### [vim-plug](https://github.com/junegunn/vim-plug)

```vim
Plug 'nvim-lualine/lualine.nvim'
" If you want to have icons in your statusline choose one of these
Plug 'nvim-tree/nvim-web-devicons'
```

### [packer.nvim](https://github.com/wbthomason/packer.nvim)

```lua
use {
  'nvim-lualine/lualine.nvim',
  requires = { 'nvim-tree/nvim-web-devicons', opt = true }
}
```

### [lazy.nvim](https://github.com/folke/lazy.nvim)

```lua
{
    'nvim-lualine/lualine.nvim',
    dependencies = { 'nvim-tree/nvim-web-devicons' }
}
```

You'll also need to have a patched font if you want icons.

## Usage and customization

Lualine has sections as shown below.

```text
+-------------------------------------------------+
| A | B | C                             X | Y | Z |
+-------------------------------------------------+
```

Each sections holds its components e.g. Vim's current mode.

### Configuring lualine in init.vim

All the examples below are in lua. You can use the same examples
in `.vim` files by wrapping them in lua heredoc like this:

```vim
lua << END
require('lualine').setup()
END
```

For more information, check out `:help lua-heredoc`.

#### Default configuration

```lua
require('lualine').setup {
  options = {
    icons_enabled = true,
    theme = 'auto',
    component_separators = { left = '', right = ''},
    section_separators = { left = '', right = ''},
    disabled_filetypes = {
      statusline = {},
      winbar = {},
    },
    ignore_focus = {},
    always_divide_middle = true,
    globalstatus = false,
    refresh = {
      statusline = 1000,
      tabline = 1000,
      winbar = 1000,
    }
  },
  sections = {
    lualine_a = {'mode'},
    lualine_b = {'branch', 'diff', 'diagnostics'},
    lualine_c = {'filename'},
    lualine_x = {'encoding', 'fileformat', 'filetype'},
    lualine_y = {'progress'},
    lualine_z = {'location'}
  },
  inactive_sections = {
    lualine_a = {},
    lualine_b = {},
    lualine_c = {'filename'},
    lualine_x = {'location'},
    lualine_y = {},
    lualine_z = {}
  },
  tabline = {},
  winbar = {},
  inactive_winbar = {},
  extensions = {}
}
```

If you want to get your current lualine config, you can
do so with:

```lua
require('lualine').get_config()

```

---

### Starting lualine

```lua
require('lualine').setup()
```

---

### Setting a theme

```lua
options = { theme = 'gruvbox' }
```

All available themes are listed in [THEMES.md](./THEMES.md).

Please create a PR if you managed to port a popular theme before us, [here is how to do it](./CONTRIBUTING.md).

#### Customizing themes

```lua
local custom_gruvbox = require'lualine.themes.gruvbox'

-- Change the background of lualine_c section for normal mode
custom_gruvbox.normal.c.bg = '#112233'

require('lualine').setup {
  options = { theme  = custom_gruvbox },
  ...
}
```

Theme structure is available [here](https://github.com/nvim-lualine/lualine.nvim/wiki/Writing-a-theme).

---

### Separators

lualine defines two kinds of separators:

- `section_separators` - separators between sections
- `component_separators` - separators between the different components in sections

**Note**: if viewing this README in a browser, chances are the characters below will not be visible.

```lua
options = {
  section_separators = { left = '', right = '' },
  component_separators = { left = '', right = '' }
}
```

Here, left refers to the left-most sections (a, b, c), and right refers
to the right-most sections (x, y, z).

#### Disabling separators

```lua
options = { section_separators = '', component_separators = '' }
```

---

### Changing components in lualine sections

```lua
sections = {lualine_a = {'mode'}}
```

#### Available components

- `branch` (git branch)
- `buffers` (shows currently available buffers)
- `diagnostics` (diagnostics count from your preferred source)
- `diff` (git diff status)
- `encoding` (file encoding)
- `fileformat` (file format)
- `filename`
- `filesize`
- `filetype`
- `hostname`
- `location` (location in file in line:column format)
- `mode` (vim mode)
- `progress` (%progress in file)
- `searchcount` (number of search matches when hlsearch is active)
- `selectioncount` (number of selected characters or lines)
- `tabs` (shows currently available tabs)
- `windows` (shows currently available windows)

#### Custom components

##### Lua functions as lualine component

```lua
local function hello()
  return [[hello world]]
end
sections = { lualine_a = { hello } }
```

##### Vim functions as lualine component

```lua
sections = { lualine_a = {'FugitiveHead'} }
```

##### Vim's statusline items as lualine component

```lua
sections = { lualine_c = {'%=', '%t%m', '%3p'} }
```

##### Vim variables as lualine component

Variables from `g:`, `v:`, `t:`, `w:`, `b:`, `o:`, `to:`, `wo:`, `bo:` scopes can be used.

See `:h lua-vim-variables` and `:h lua-vim-options` if you are not sure what to use.

```lua
sections = { lualine_a = { 'g:coc_status', 'bo:filetype' } }
```

##### Lua expressions as lualine component

You can use any valid lua expression as a component including:

- oneliners
- global variables
- require statements

```lua
sections = { lualine_c = { "os.date('%a')", 'data', "require'lsp-status'.status()" } }
```

`data` is a global variable in this example.

---

### Component options

Component options can change the way a component behave.
There are two kinds of options:

- global options affecting all components
- local options affecting specific

Global options can be used as local options (can be applied to specific components)
but you cannot use local options as global.
Global option used locally overwrites the global, for example:

```lua
    require('lualine').setup {
      options = { fmt = string.lower },
      sections = { lualine_a = {
        { 'mode', fmt = function(str) return str:sub(1,1) end } },
                  lualine_b = {'branch'} }
    }
```

`mode` will be formatted with the passed function so only first char will be
shown . On the other hand branch will be formatted with global formatter
`string.lower` so it will be showed in lower case.

#### Available options

#### Global options

These are `options` that are used in options table.
They set behavior of lualine.

Values set here are treated as default for other options
that work in component level.

For example even though `icons_enabled` is a general component option.
You can set `icons_enabled` to `false` and icons will be disabled on all
component. You can still overwrite defaults set in option table by specifying
the option value in component.

```lua
options = {
  theme = 'auto', -- lualine theme
  component_separators = { left = '', right = '' },
  section_separators = { left = '', right = '' },
  disabled_filetypes = {     -- Filetypes to disable lualine for.
      statusline = {},       -- only ignores the ft for statusline.
      winbar = {},           -- only ignores the ft for winbar.
  },

  ignore_focus = {},         -- If current filetype is in this list it'll
                             -- always be drawn as inactive statusline
                             -- and the last window will be drawn as active statusline.
                             -- for example if you don't want statusline of
                             -- your file tree / sidebar window to have active
                             -- statusline you can add their filetypes here.

  always_divide_middle = true, -- When set to true, left sections i.e. 'a','b' and 'c'
                               -- can't take over the entire statusline even
                               -- if neither of 'x', 'y' or 'z' are present.

  globalstatus = false,        -- enable global statusline (have a single statusline
                               -- at bottom of neovim instead of one for  every window).
                               -- This feature is only available in neovim 0.7 and higher.

  refresh = {                  -- sets how often lualine should refresh it's contents (in ms)
    statusline = 1000,         -- The refresh option sets minimum time that lualine tries
    tabline = 1000,            -- to maintain between refresh. It's not guarantied if situation
    winbar = 1000              -- arises that lualine needs to refresh itself before this time
                               -- it'll do it.

                               -- Also you can force lualine's refresh by calling refresh function
                               -- like require('lualine').refresh()
  }
}
```

#### General component options

These are options that control behavior at component level
and are available for all components.

```lua
sections = {
  lualine_a = {
    {
      'mode',
      icons_enabled = true, -- Enables the display of icons alongside the component.
      -- Defines the icon to be displayed in front of the component.
      -- Can be string|table
      -- As table it must contain the icon as first entry and can use
      -- color option to custom color the icon. Example:
      -- {'branch', icon = ''} / {'branch', icon = {'', color={fg='green'}}}

      -- icon position can also be set to the right side from table. Example:
      -- {'branch', icon = {'', align='right', color={fg='green'}}}
      icon = nil,

      separator = nil,      -- Determines what separator to use for the component.
                            -- Note:
                            --  When a string is provided it's treated as component_separator.
                            --  When a table is provided it's treated as section_separator.
                            --  Passing an empty string disables the separator.
                            --
                            -- These options can be used to set colored separators
                            -- around a component.
                            --
                            -- The options need to be set as such:
                            --   separator = { left = '', right = ''}
                            --
                            -- Where left will be placed on left side of component,
                            -- and right will be placed on its right.
                            --

      cond = nil,           -- Condition function, the component is loaded when the function returns `true`.

      draw_empty = false,   -- Whether to draw component even if it's empty.
                            -- Might be useful if you want just the separator.

      -- Defines a custom color for the component:
      --
      -- 'highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' } | function
      -- Note:
      --  '|' is synonymous with 'or', meaning a different acceptable format for that placeholder.
      -- color function has to return one of other color types ('highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' })
      -- color functions can be used to have different colors based on state as shown below.
      --
      -- Examples:
      --   color = { fg = '#ffaa88', bg = 'grey', gui='italic,bold' },
      --   color = { fg = 204 }   -- When fg/bg are omitted, they default to the your theme's fg/bg.
      --   color = 'WarningMsg'   -- Highlight groups can also be used.
      --   color = function(section)
      --      return { fg = vim.bo.modified and '#aa3355' or '#33aa88' }
      --   end,
      color = nil, -- The default is your theme's color for that section and mode.

      -- Specify what type a component is, if omitted, lualine will guess it for you.
      --
      -- Available types are:
      --   [format: type_name(example)], mod(branch/filename),
      --   stl(%f/%m), var(g:coc_status/bo:modifiable),
      --   lua_expr(lua expressions), vim_fun(viml function name)
      --
      -- Note:
      -- lua_expr is short for lua-expression and vim_fun is short for vim-function.
      type = nil,

      padding = 1, -- Adds padding to the left and right of components.
                   -- Padding can be specified to left or right independently, e.g.:
                   --   padding = { left = left_padding, right = right_padding }

      fmt = nil,   -- Format function, formats the component's output.
                   -- This function receives two arguments:
                   -- - string that is going to be displayed and
                   --   that can be changed, enhanced and etc.
                   -- - context object with information you might
                   --   need. E.g. tabnr if used with tabs.
      on_click = nil, -- takes a function that is called when component is clicked with mouse.
                   -- the function receives several arguments
                   -- - number of clicks in case of multiple clicks
                   -- - mouse button used (l(left)/r(right)/m(middle)/...)
                   -- - modifiers pressed (s(shift)/c(ctrl)/a(alt)/m(meta)...)
    }
  }
}

        -- Same values as the general color option can be used here.
        active = 'lualine_{section}_normal',     -- Color for active tab.

      show_modified_status = true, -- Shows indicator when the window is modified.

      },
    }
  }
}

### Tabline

You can use lualine to display components in tabline.
The configuration for tabline sections is exactly the same as that of the statusline.

```lua
tabline = {
  lualine_a = {},
  lualine_b = {'branch'},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}
```

This will show the branch and filename components on top of neovim inside tabline.

lualine also provides 2 components, buffers and tabs, that you can use to get a more traditional tabline/bufferline.

```lua
tabline = {
  lualine_a = {'buffers'},
  lualine_b = {'branch'},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {'tabs'}
}
```

### Winbar

From neovim-0.8 you can customize your winbar with lualine.
Winbar configuration is similar to statusline.

```lua
winbar = {
  lualine_a = {},
  lualine_b = {},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}

inactive_winbar = {
  lualine_a = {},
  lualine_b = {},
  lualine_c = {'filename'},
  lualine_x = {},
  lualine_y = {},
  lualine_z = {}
}
```

Just like statusline you can separately specify winbar for active and inactive
windows. Any lualine component can be placed in winbar. All kinds of custom
components supported in statusline are also supported for winbar too. In general
You can treat winbar as another lualine statusline that just appears on top
of windows instead of at bottom.

#### Buffers

Shows currently open buffers. Like bufferline . See
[buffers options](#buffers-component-options)
for all builtin behaviors of buffers component.
You can use `:LualineBuffersJump` to jump to buffer based on index
of buffer in buffers component.
Jumping to non-existent buffer indices generates an error. To avoid these errors
`LualineBuffersJump` provides `<bang>` support, meaning that you can call
`:LualineBufferJump!` to ignore these errors.

```vim
  :LualineBuffersJump 2  " Jumps to 2nd buffer in buffers component.
  :LualineBuffersJump $  " Jumps to last buffer in buffers component.
  :LualineBuffersJump! 3  " Attempts to jump to 3rd buffer, if it exists.
```

#### Tabs

Shows currently open tab. Like usual tabline. See
[tabs options](#tabs-component-options)
for all builtin behaviors of tabs component.
You can also use `:LualineRenameTab` to set a name for a tabpage.
For example:

```vim
:LualineRenameTab Project_K
```

It's useful when you're using rendering mode 2/3 in tabs.
To unname a tabpage run `:LualineRenameTab` without argument.

#### Tabline as statusline

You can also completely move your statusline to a tabline by configuring
`lualine.tabline` and disabling `lualine.sections` and `lualine.inactive_sections`:

```lua
tabline = {
......
  },
sections = {},
inactive_sections = {},
```

If you want a more sophisticated tabline you can use other
tabline plugins with lualine too, for example:

- [nvim-bufferline](https://github.com/akinsho/nvim-bufferline.lua)
- [tabline.nvim](https://github.com/kdheepak/tabline.nvim)

tabline.nvim even uses lualine's theme by default 🙌
You can find a bigger list [here](https://github.com/rockerBOO/awesome-neovim#tabline).

### Extensions

lualine extensions change statusline appearance for a window/buffer with
specified filetypes.

By default no extensions are loaded to improve performance.
You can load extensions with:

```lua
extensions = {'quickfix'}
```

#### Available extensions

- aerial
- chadtree
- ctrlspace
- fern
- fugitive
- fzf
- lazy
- man
- mason
- mundo
- neo-tree
- nerdtree
- nvim-dap-ui
- nvim-tree
- oil
- overseer
- quickfix
- symbols-outline
- toggleterm
- trouble

#### Custom extensions

You can define your own extensions. If you believe an extension may be useful to others, then please submit a PR.

```lua
local my_extension = { sections = { lualine_a = {'mode'} }, filetypes = {'lua'} }
require('lualine').setup { extensions = { my_extension } }
```

---

### Refreshing lualine

By default lualine refreshes itself based on timer and some events. You can set
the interval of the timer with refresh option. However you can also force
lualine to refresh at any time by calling `lualine.refresh` function.

```lua
require('lualine').refresh({
  scope = 'tabpage',  -- scope of refresh all/tabpage/window
  place = { 'statusline', 'winbar', 'tabline' },  -- lualine segment ro refresh.
})
```

The arguments shown here are default values. So not passing any of them will be
treated as if a default value was passed.

So you can simply do

```lua
require('lualine').refresh()
```

Avoid calling `lualine.refresh` inside components. Since components are evaluated
during refresh, calling refresh while refreshing can have undesirable effects.

### Disabling lualine

You can disable lualine for specific filetypes:

```lua
options = { disabled_filetypes = {'lua'} }
```

You can also disable lualine completely.
Note that you need to call this after the setup

```lua
  require('lualine').hide({
    place = {'statusline', 'tabline', 'winbar'}, -- The segment this change applies to.
    unhide = false,  -- whether to re-enable lualine again/
  })
```

The arguments show for hide above are default values.
Which means even if the hide function is called without
arguments it'll work as if these were passed.

So in short to disable lualine completely you can do

```lua
require('lualine').hide()
```

To enable it again you can do

```lua
require('lualine').hide({unhide=true})
```
