## 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.

## 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 'kyazdani42/nvim-web-devicons'
|
|
```
|
|
|
|
### [packer.nvim](https://github.com/wbthomason/packer.nvim)
|
|
|
|
```lua
|
|
use {
|
|
'nvim-lualine/lualine.nvim',
|
|
requires = { 'kyazdani42/nvim-web-devicons', opt = true }
|
|
}
|
|
```
|
|
|
|
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 = {},
|
|
always_divide_middle = true,
|
|
globalstatus = false,
|
|
},
|
|
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 = {},
|
|
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
|
|
- `components_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)
|
|
- `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`, `go:`, `vo:`, `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.
|
|
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.
|
|
}
|
|
```
|
|
|
|
#### 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`.
|
|
|
|
-- 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.
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
#### Component specific options
|
|
|
|
These are options that are available on specific components.
|
|
For example you have option on `diagnostics` component to
|
|
specify what your diagnostic sources will be.
|
|
|
|

### 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'}
|
|
}
|
|
```
|
|
|
|
#### 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.
|
|
```vim
|
|
:LualineBuffersJump 2 " Jumps to 2nd buffer in buffers component.
|
|
:LualineBuffersJump $ " Jumps to last buffer in buffers component.
|
|
```
|
|
|
|
#### 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 tablage 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
|
|
- fern
|
|
- fugitive
|
|
- fzf
|
|
- nerdtree
|
|
- neo-tree
|
|
- nvim-tree
|
|
- quickfix
|
|
- symbols-outline
|
|
- toggleterm
|
|
|
|
#### 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 } }
|
|
```
|
|
|

|
### Disabling lualine
|
|
|
|
You can disable lualine for specific filetypes:
|
|
|
|
```lua
|
|
options = { disabled_filetypes = {'lua'} }
|
|
```
