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* Global options ~ > options = { icons_enabled = true, -- displays icons in alongside component padding = 1, -- adds padding to the left and right of components -- padding can be specified to left or right separately like -- padding = { left = left_padding, right = right_padding } fmt = nil -- fmt function, formats component's output } < Local options ~ > sections = { lualine_a = { { 'mode', icon = nil, -- displays icon in front of the component separator = nil, -- Determines what separator to use for the component. -- when a string is given it's treated as component_separator. -- When a table is given it's treated as section_separator. -- This options can be used to set colored separators -- arround component.

By default no extension are loaded to improve performance. You can load extensions with: > extensions = {'quickfix'} < Available extensions ~ - chadtree - fugitive - fzf - nerdtree - nvim-tree - quickfix Custom extensions ~ You can define your own extensions.
