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 *lualine_installation* VIM-PLUG *lualine_vim-plug* > 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 *lualine_packer.nvim* > use { 'hoob3rt/lualine.nvim', requires = {'kyazdani42/nvim-web-devicons', opt = true} } < -------------------------------------------------------------------------------- USAGE AND CUSTOMIZATION *lualine_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. Colorscheme of sections is mirrored, meaning section `A` will have the same colorscheme as section `Z` etc. Configuration is currently limited to lua, please use lua block or a separate lua file to configure lualine. STARTING LUALINE *lualine_starting_lualine* > local lualine = require('lualine') lualine.status() < SETTING THEME *lualine_setting_theme* > lualine.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). CHANGING SEPARATOR IN SECTION *lualine_changing_separator* Lualine defines two kinds of seperators. One is for sections and other is for components. Default section seperators are '', '' and component separators are '', ''.They require powerline patched fonts. But you can easily change yours to something else like below. > lualine.section_separators = {'', ''} lualine.component_separators = {'', ''} < or disable it > lualine.section_separators = nil lualine.component_separators = nil < CHANGING COMPONENTS IN LUALINE SECTIONS *lualine_changing_components* Lualine defaults~ > lualine.sections = { lualine_a = { 'mode' }, lualine_b = { 'branch' }, lualine_c = { 'filename' }, lualine_x = { 'encoding', 'fileformat', 'filetype' }, lualine_y = { 'progress' }, lualine_z = { 'location' }, } lualine.inactive_sections = { lualine_a = { }, lualine_b = { }, lualine_c = { 'filename' }, lualine_x = { 'location' }, lualine_y = { }, lualine_z = { } } < Available components~ general~ * branch (git branch) * diagnostics (diagnostics count from your prefered source) * encoding (file encoding) * fileformat (file format) * filename * filetype * location (location in file in line:column format) * mode (vim mode) * progress (%progress in file) plugin~ * signify (signify status) -------------------------------------------------------------------------------- BUILDING YOUR COMPONENTS *lualine_custom_components* Using custom functions as lualine component~ You can define a custom function as a lualine component > local function hello() return [[hello world]] end lualine.sections.lualine_a = { hello } < Using vim functions as lualine component~ You can use vim functions as a lualine component > lualine.sections.lualine_b = { 'FugitiveHead' } < Using variables as lualine component~ You can use variables from vim and lua globals as a lualine component Variables from g:, v:, t:, w:, b:, o, go:, vo:, to:, wo:, bo: scopes can be used. Scopes ending with o are options usualy accessed with `&` in vimscript > lualine.sections.lualine_b = { 'g:coc_status', 'bo:filetype' } lualine.sections.lualine_x = { 'vim.bo.fileencoding' } < -------------------------------------------------------------------------------- CUSTOM OPTIONS FOR COMPONENTS *lualine_custom_options* Options for components~ ====================== Global Default options~ ---------------------- Default options act as default for all components icons_enabled (Default: true) Displays icons on components You should have nerd-fonts supported fonts to see icons properly. Suported by branch, fileformat, filetype, location Example: `lualine.options.icons_enabled = true` Genaral options~ --------------- These options are available for all components. option (default_value) ------ --------------- • padding (1) spaces on left and right • left_padding (1) spaces on left • icon (depends on component) displays an icon infront of a component • icons_enabled (true) whether to show icon(if available) • right_padding (1) spaces on right • separator ('|') which separator to use at end of component • upper (false) Displayed in upper case • lower (false) Displayed in lower case • format (nil) Takes a function . The funtion gets the result of component as argument and it's return value is displayed. So this function can parse and format the output as user wants. • color (Theme colors) color option can be used to set custom color to a component Color format: `lua color = {fg = '#rrggbb', bg= '#rrggbb', gui='style'}` the members of color table are optional and default to theme Component specific options~ -------------------------- These options are available for specific components only. List of options are given below. • diagnostics~ • sources (nil) displays diagnostic count from defined source. array containing one or many string from set {'nvim_lsp', 'coc', 'ale'} • sections ({'error', 'warn', 'info'}) displays diagnostics of defined severity. array containing one or many string from set {'error', 'warn', 'info'} • color_error (DiffDelete foreground color) changes diagnostic's error section foreground color. color in #rrggbb format • color_warn (DiffText foreground color) changes diagnostic's warn section foreground color color in #rrggbb format • color_info (Normal foreground color) changes diagnostic's info section foreground color color in #rrggbb format • symbols (icons_enabled: true -> {error = ' ', warn = ' ', info = ' '}) (icons_enabled: false -> {error = 'E:', warn = 'W:', info = 'I:'}) changes diagnostic's symbol characters. You can set one or more symbols for each level. > { 'diagnostics', symbols = { -- set the error symbol and use defaults for warn and info. error = '!!', }, } < • filename~ • file_status (true) Whether to display filemodified status in filename • shorten (true) Whether to display full/relative path with filename • full_path (false) Whether to display full path when shorten is false • fileformat~ • icons_enabled (true) Whether to displays icon before component. Colors are automaticaly extracted from colorscheme . If you want to change any of those you can use options given below. • signify~ • colored (true) Whether to show colors • color_added (DiffAdd foreground color) Foreground color of added section • color_modified (DiffChange foreground color) Foreground color of modified section • color_removed (DiffDelete foreground color) Foreground color of removed section Example:~ > lualine.sections.lualine_b = { { 'branch', icon = '', upper = true, color = { fg = '#00aa22' } }, { 'filename', full_name = true, shorten = true, format = function(name) -- Capitalize first charecter of filename to capital. local path, fname = name:match('(.*/)(.*)') if not path then path = ''; fname = name end return path .. fname:sub(1, 1):upper() .. fname:sub(2, #fname) end } } < -------------------------------------------------------------------------------- LOADING PLUGIN EXTENSIONS *lualine_loading_plugin_extensions* Lualine extensions change statusline appearance for a window/buffer with a plugin loaded e.g. junegunn/fzf.vim (https://github.com/junegunn/fzf.vim) By default no plugin extension are loaded to improve performance.
