PERFORMANCE COMPARED TO OTHER PLUGINS*lualine-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                                            *lualine-installation*

VIM-PLUG <HTTPS://GITHUB.COM/JUNEGUNN/VIM-PLUG> ~

>
    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> ~

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

USAGE AND CUSTOMIZATION                      *lualine-usage-and-customization*

Lualine has sections as shown below.

>
    +-------------------------------------------------+
    | 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:

>
    lua << END
    require('lualine').setup()
    END
<


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

------------------------------------------------------------------------------

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.

>
    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).

LUA FUNCTIONS AS LUALINE COMPONENT

>
    local function hello()
      return [[hello world]]
    end
    sections = { lualine_a = { hello } }
<


VIM FUNCTIONS AS LUALINE COMPONENT

>
    sections = { lualine_a = {'FugitiveHead'} }
<


VIM’S STATUSLINE ITEMS AS LUALINE COMPONENT

>
    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.

>
    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


>
    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:

>
        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.

                                                   *lualine-Available-options*

                                                      *lualine-Global-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.

TABLINE ~

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

>
    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.

>
    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.

>
    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.

                                                             *lualine-Buffers*

Buffers                                Shows currently open buffers. Like
                                       bufferline. See
                                       |lualine-buffers-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.


>
      :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.

                                                                *lualine-Tabs*

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


>
    :LualineRenameTab Project_K
<


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

                                               *lualine-Tabline-as-statusline*

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`:


>
    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:

    extensions = {'quickfix'}

                                       you believe an extension may be useful
                                       to others, then please submit a PR.

<


------------------------------------------------------------------------------

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.

>
    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

>
    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:

>
    options = { disabled_filetypes = {'lua'} }
<


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

>
      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

>
    require('lualine').hide()
<


To enable it again you can do

>
    require('lualine').hide({unhide=true})
<
