# lualine.nvim ![code size](https://img.shields.io/github/languages/code-size/hoob3rt/lualine.nvim?style=flat-square) ![license](https://img.shields.io/github/license/hoob3rt/lualine.nvim?style=flat-square) A blazing fast and easy to configure neovim statusline written in pure lua. `lualine.nvim` requires neovim 0.5 ## Contributing Feel free to create an issue/pr if you want to see anything else implemented. Please read [CONTRIBUTING.md](./CONTRIBUTING.md) before opening a pr. ## Screenshots Here is a preview of how lualine can look like.

Screenshots of all available themes are listed in [THEMES.md](./THEMES.md) For those who want to break the norms. You can create custom looks in lualine. **Example** : - [evil_lualine](https://gist.github.com/hoob3rt/b200435a765ca18f09f83580a606b878) ## Performance compared to other plugins Unlike other statusline plugins lualine loads only defined components, nothing else. Startup time performance measured with an amazing plugin [tweekmonster/startuptime.vim](https://github.com/tweekmonster/startuptime.vim) All times are measured with only `startuptime.vim` and given statusline plugin installed | clean vimrc | lualine | lightline | airline | | :------------: | :----------: | :----------: | :----------: | | 8.943 ms | 9.034 ms | 11.463 ms | 13.425 ms | ## Installation ### [vim-plug](https://github.com/junegunn/vim-plug) ```vim Plug 'hoob3rt/lualine.nvim' " If you want to have icons in your statusline choose one of these Plug 'kyazdani42/nvim-web-devicons' Plug 'ryanoasis/vim-devicons' ``` ### [packer.nvim](https://github.com/wbthomason/packer.nvim) ```lua use { 'hoob3rt/lualine.nvim', requires = {'kyazdani42/nvim-web-devicons', opt = true} } ``` ## Usage and customization Lualine has sections as shown below. ``` +-------------------------------------------------+ | A | B | C X | Y | Z | +-------------------------------------------------+ ``` Each sections holds it's components e.g. current vim's mode.
Default config ```lua require'lualine'.setup { options = { icons_enabled = true, theme = 'gruvbox', component_separators = {'', ''}, section_separators = {'', ''}, disabled_filetypes = {} }, sections = { lualine_a = {'mode'}, lualine_b = {'branch'}, 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 me, [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' -- rgb colors are supported require'lualine'.setup{ options = { theme = custom_gruvbox }, ... } ``` Theme structure is available [here](https://github.com/hoob3rt/lualine.nvim/blob/master/CONTRIBUTING.md#adding-a-theme)
--- ### Separators Lualine defines two kinds of seperators: * `section_separators` - separators between sections * `components_separators` - separators between components in sections ```lua options = { section_separators = {'', ''}, component_separators = {'', ''} } ```
Disabling separators ```lua options = {section_separators = '', component_separators = ''} ```
--- ### Changing components in lualine sections ```lua sections = {lualine_a = {'mode'}} ```
Available components * `branch` (git branch) * `diagnostics` (diagnostics count from your prefered source) * `encoding` (file encoding) * `fileformat` (file format) * `filename` * `filetype` * `hostname` * `location` (location in file in line:column format) * `mode` (vim mode) * `progress` (%progress in file) * `diff` (git diff status)
#### 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 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.data('%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 = {lower = true}, sections = {lualine_a = {{'mode', lower = false}}, lualine_b = {'branch'}} } ``` `mode` will be displayed with `lower = false` and `branch` will be displayed with `lower = true` #### Available options
Global options ```lua options = { icons_enabled = 1, -- displays icons in alongside component padding = 1, -- adds padding to the left and right of components left_padding = 1, -- adds padding to the left of components right_padding =1, -- adds padding to the right of components upper = false, -- displays components in uppercase lower = false, -- displays components in lowercase format = nil -- format function, formats component's output } ```
Local options ```lua sections = { lualine_a = { { 'mode', icon = nil, -- displays icon in front of the component separator = nil, -- Determines what separator to use for the component. condition = nil, -- condition function, component is loaded when function returns true -- custom color for component in format -- color = {fg = '#rrggbb', bg= '#rrggbb', gui='style'} -- or highlight group -- color = "WarningMsg" color = nil } } } ```
Component specific local options #### `diagnostics` component options ```lua sections = { lualine_a = { { 'diagnostics', -- table of diagnostic sources, available sources: -- nvim_lsp, coc, ale, vim_lsp sources = nil, -- displays diagnostics from defined severity sections = {'error', 'warn', 'info', 'hint'}, -- all colors are in format #rrggbb color_error = nil, -- changes diagnostic's error foreground color color_warn = nil, -- changes diagnostic's warn foreground color color_info = nil, -- Changes diagnostic's info foreground color color_hint = nil, -- Changes diagnostic's hint foreground color symbols = {error = 'E', warn = 'W', info = 'I', hint = 'H'} update_in_insert = false, -- Update diagnostics in insert mode } } } ``` #### `filename` component options ```lua sections = { lualine_a = { { 'filename', file_status = true, -- displays file status (readonly status, modified status) path = 0 -- 0 = just filename, 1 = relative path, 2 = absolute path } } } ``` #### `filetype` component options ```lua sections = { lualine_a = { { 'filetype', colored = true, -- displays filetype icon in color if set to `true disable_text = false -- Display only icon for filetype } } } ``` #### `diff` component options ```lua sections = { lualine_a = { { 'diff', colored = true, -- displays diff status in color if set to true -- all colors are in format #rrggbb color_added = nil, -- changes diff's added foreground color color_modified = nil, -- changes diff's modified foreground color color_removed = nil, -- changes diff's removed foreground color symbols = {added = '+', modified = '~', removed = '-'} -- changes diff symbols source = nil, -- A function that works as a data source for diff. -- it must return a table like {added = add_count, modified = modified_count, removed = removed_count } -- Or nil on failure. Count <= 0 won't be displayed. } } } ```
--- ### Tabline You can use lualine to display components in tabline. The configuration for tabline sections is exactly the same as for statusline. ```lua 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 . You can also completely move your statuline to tabline by configuring `lualine.tabline` and disabling `lualine.sections` and `lualine.inactive_sections`. ```lua tabline = { ...... }, sections = {}, inactive_sections = {}, ``` If you're looking for bufferline or want to show tabs in tabline . There are manny awesome plugins that can do that. 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 extension are loaded to improve performance. You can load extensions with: ```lua extensions = {'quickfix'} ```
Available extensions * chadtree * fugitive * fzf * nerdtree * nvim-tree * quickfix
Custom extensions You can define your own extensions. If you think an extension might be useful for 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'}} ```
