Statusline

LunarVim uses lualine as a default statusline.

Configuration is same as that of lualine with full support. See Lualine README.md

In addition, LunarVim provides predefined styles(layout) and components.

Style

There are three style options LunarVim accepts,

• lvim

  LunarVim's default layout

• default

  Lualine's default layout

• none

  Empty layout

To set style other than "lvim" style,

lvim.builtin.lualine.style = "default" -- or "none"

Component

You can use any component that lualine provides and LunarVim provides.

LunarVim's components

mode, branch, filename, diff, python_env, diagnostics, treesitter, lsp, location, progress, spaces, encoding, filetype, scrollbar

To set lualine's "diff" component to section c of "default" style,

lvim.builtin.lualine.style = "default"
lvim.builtin.lualine.sections.lualine_c = { "diff" }

To set LunarVim's "spaces" and "location" components to section y and lualine's "mode" component to section a of "lvim" style,

-- no need to set style = "lvim"
local components = require("lvim.core.lualine.components")

lvim.builtin.lualine.sections.lualine_a = { "mode" }
lvim.builtin.lualine.sections.lualine_y = {
  components.spaces,
  components.location
}

Theme

LunarVim automatically detects current colorscheme and set it as theme.

To change your colorscheme, see Colorscheme

If there is no matching theme, it will fallback to "auto" theme provided by lualine.

In case you want to use different theme, set it manually,

lvim.builtin.lualine.options.theme = "gruvbox"

To customize existing theme,

local custom_gruvbox = require "lualine.themes.gruvbox_dark"
custom_gruvbox.insert.b = { fg = custom_gruvbox.insert.a.bg, gui = "bold" }
custom_gruvbox.visual.b = { fg = custom_gruvbox.visual.a.bg, gui = "bold" }
custom_gruvbox.replace.b = { fg = custom_gruvbox.replace.a.bg, gui = "bold" }
custom_gruvbox.command.b = { fg = custom_gruvbox.command.a.bg, gui = "bold" }

lvim.builtin.lualine.options.theme = custom_gruvbox

To create your own theme,

local colors = {
  color2 = "#0f1419",
  color3 = "#ffee99",
  color4 = "#e6e1cf",
  color5 = "#14191f",
  color13 = "#b8cc52",
  color10 = "#36a3d9",
  color8 = "#f07178",
  color9 = "#3e4b59",
}

lvim.builtin.lualine.options.theme = {
  normal = {
    c = { fg = colors.color9, bg = colors.color2 },
    a = { fg = colors.color2, bg = colors.color10, gui = "bold" },
    b = { fg = colors.color4, bg = colors.color5 },
  },
  insert = {
    a = { fg = colors.color2, bg = colors.color13, gui = "bold" },
    b = { fg = colors.color4, bg = colors.color5 },
  },
  visual = {
    a = { fg = colors.color2, bg = colors.color3, gui = "bold" },
    b = { fg = colors.color4, bg = colors.color5 },
  },
  replace = {
    a = { fg = colors.color2, bg = colors.color8, gui = "bold" },
    b = { fg = colors.color4, bg = colors.color5 },
  },
  inactive = {
    c = { fg = colors.color4, bg = colors.color2 },
    a = { fg = colors.color4, bg = colors.color5, gui = "bold" },
    b = { fg = colors.color4, bg = colors.color5 },
  },
}

Callback

Callback function is available for more flexibility.

It will run when configuration is done,

lvim.builtin.lualine.on_config_done = function(lualine)
  local config = lualine.get_config()
  local components = require "core.lualine.components"

  config.sections.lualine_x[3].color.bg = "#2c2c2c"
  table.remove(config.sections.lualine_x, 2) -- remove treesitter icon
  table.insert(config.sections.lualine_x, components.location)
  lualine.setup(config)
end
