PERFORMANCE COMPARED TO OTHER PLUGINS*lualine-performance-compared-to-other-plugins*
|
||
|
||
Unlike other statusline plugins lualine loads only defined components, nothing
|
||
else.
|
||
|
||
Startup time performance measured with an amazing plugin
|
||
dstein64/vim-startuptime <https://github.com/dstein64/vim-startuptime>
|
||
|
||
All times are measured with 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 average
|
||
of 20 runs.

INSTALLATION *lualine-installation*

USAGE AND CUSTOMIZATION *lualine-usage-and-customization*
|
||
|
||
Lualine has sections as shown below.

*lualine-Configuring-lualine-in-init.vim*
|
||
|

Configuring lualine in init.vim All the examples below are in lua. You
|

can use the same examples in `.vim` file
|
||
by wrapping them in lua heredoc like
|
||
this:
|
||
|
||
|
||
>
|
||
lua << END
|

require'lualine'.setup()

SEPARATORS ~
|
||
|
||
Lualine defines two kinds of separators:
|
||
|
||
|
||
- `section_separators` - separators between sections
|
||
- `components_separators` - separators between components in sections
|
||
|
||
|
||
>
|
||
options = {
|
||
section_separators = { left = '', right = ''},
|
||
component_separators = { left = '', right = ''}
|
||
}
|
||
<
|
||
|
||
|
||
Here left means it’ll be used for left sections (a, b, c) and right means
|
||
it’ll be used for right sections (x, y, z).

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 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 fa=unction 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.

||

||

|
||

|
||
theme = 'auto', -- lualine theme

*lualine-General-component-options*
|
||

|
||
at component level and are available for
|
||
all components.

|

-- around a component.
|

--
|
||
-- The options need to be set like:
|
||
-- separator = { left = '', right = ''}
|
||
--
|
||
-- Where left will be placed on left side of component,
|
||
-- and right will be placed on its right.
|
||
-- Passing an empty string disables the separator.
|
||
|
||
cond = nil, -- Condition function, the component is loaded when the function returns `true`.

-- 'highlight_group_name' | {fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style'}
|
||
--
|
||
-- Note: all other color options like diff_color including themes accept same color values
|
||
--
|
||
-- example:
|
||
-- color = {fg = '#ffaa88', bg = 'grey', gui='italic,bold'},
|
||
-- color = {fg = 204} -- when fg/bg is skiped they default to themes fg/bg

color = nil, -- default is themes color for that section and mode

TABLINE ~
|
||
|
||
You can use lualine to display components in tabline. The configuration for
|
||
tabline sections is exactly the same as for statusline.
|
||
|
||
>
|
||
tabline = {
|
||
lualine_a = {},
|
||
lualine_b = {'branch'},
|
||
lualine_c = {'filename'},
|
||
lualine_x = {},
|
||
lualine_y = {},
|
||
lualine_z = {}
|
||
}
|
||
<
|
||
|
||
|
||
This will show branch and filename component in top of neovim inside tabline.
|
||
|
||
lualine also provides 2 components buffers & tabs that you can use to get more
|
||
traditional tabline/bufferline.
|
||
|
||
>
|
||
tabline = {
|
||
lualine_a = {'buffers'},
|
||
lualine_b = {'branch'},
|
||
lualine_c = {'filename'},
|
||
lualine_x = {},
|
||
lualine_y = {},
|
||
lualine_z = {'tabs'}
|
||
}
|
||
<
|
||
|
||
|
||
You can also completely move your statusline to 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 lualines 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'}
|
||
<
|
||
|
||
|
||
*lualine-Available-extensions*
|
||
|
||
|
||
- chadtree
|
||
- fern
|
||
- fugitive
|
||
- fzf
|
||
- nerdtree
|
||
- nvim-tree
|
||
- quickfix
|
||
- toggleterm
|
||
- symbols-outline
|
||
|
||
|
||
*lualine-Custom-extensions*
|
||
|
||
Custom extensions You can define your own extensions. If
|
||
you think an extension might be useful
|
||
for others then please submit a pr.
|
||
|
||
|
||
>
|
||
local my_extension = {sections = {lualine_a = {'mode'}}, filetypes = {'lua'}}
|
||
require'lualine'.setup {extensions = {my_extension}}

|
||
|
||
DISABLING LUALINE ~
|
||
|
||
You can disable lualine for specific filetypes
|
||
|
||
>
|
||
options = {disabled_filetypes = {'lua'}}
