📦 Installation

Install the plugin with your preferred package manager:

lazy.nvim

-- Lua
{
  "folke/zen-mode.nvim",
  opts = {
    -- your configuration comes here
    -- or leave it empty to use the default settings
    -- refer to the configuration section below
  }
}

⚙️ Configuration

Zen Mode comes with the following defaults:

{
  window = {
    backdrop = 0.95, -- shade the backdrop of the Zen window. Set to 1 to keep the same as Normal
    -- height and width can be:
    -- * an absolute number of cells when > 1
    -- * a percentage of the width / height of the editor when <= 1
    -- * a function that returns the width or the height
    width = 120, -- width of the Zen window
    height = 1, -- height of the Zen window
    -- by default, no options are changed for the Zen window
    -- uncomment any of the options below, or add other vim.wo options you want to apply
    options = {
      -- signcolumn = "no", -- disable signcolumn
      -- number = false, -- disable number column
      -- relativenumber = false, -- disable relative numbers
      -- cursorline = false, -- disable cursorline
      -- cursorcolumn = false, -- disable cursor column
      -- foldcolumn = "0", -- disable fold column
      -- list = false, -- disable whitespace characters
    },
  },
  plugins = {
    -- disable some global vim options (vim.o...)
    -- comment the lines to not apply the options
    options = {
      enabled = true,
      ruler = false, -- disables the ruler text in the cmd line area
      showcmd = false, -- disables the command in the last line of the screen
      -- you may turn on/off statusline in zen mode by setting 'laststatus' 
      -- statusline will be shown only if 'laststatus' == 3
      laststatus = 0, -- turn off the statusline in zen mode
    },
    twilight = { enabled = true }, -- enable to start Twilight when zen mode opens
    gitsigns = { enabled = false }, -- disables git signs
    tmux = { enabled = false }, -- disables the tmux statusline
    -- this will change the font size on kitty when in zen mode
    -- to make this work, you need to set the following kitty options:
    -- - allow_remote_control socket-only
    -- - listen_on unix:/tmp/kitty
    kitty = {
      enabled = false,
      font = "+4", -- font size increment
    },
    -- this will change the font size on alacritty when in zen mode
    -- requires  Alacritty Version 0.10.0 or higher
    -- uses `alacritty msg` subcommand to change font size
    alacritty = {
      enabled = false,
      font = "14", -- font size
    },
    -- this will change the font size on wezterm when in zen mode
    -- See alse also the Plugins/Wezterm section in this projects README
    wezterm = {
      enabled = false,
      -- can be either an absolute font size or the number of incremental steps
      font = "+4", -- (10% increase per step)
    },
  },
  -- callback where you can add custom code when the Zen window opens
  on_open = function(win)
  end,
  -- callback where you can add custom code when the Zen window closes
  on_close = function()
  end,
}

🚀 Usage

Toggle Zen Mode with :ZenMode.

Alternatively you can start Zen Mode with the Lua API and pass any additional options:

require("zen-mode").toggle({
  window = {
    width = .85 -- width will be 85% of the editor width
  }
})

🧩 Plugins

Wezterm

In order to make the integration with wezterm work as intended, you need to add the following function to your wezterm config:

wezterm.on('user-var-changed', function(window, pane, name, value)
    local overrides = window:get_config_overrides() or {}
    if name == "ZEN_MODE" then
        local incremental = value:find("+")
        local number_value = tonumber(value)
        if incremental ~= nil then
            while (number_value > 0) do
                window:perform_action(wezterm.action.IncreaseFontSize, pane)
                number_value = number_value - 1
            end
            overrides.enable_tab_bar = false
        elseif number_value < 0 then
            window:perform_action(wezterm.action.ResetFontSize, pane)
            overrides.font_size = nil
            overrides.enable_tab_bar = true
        else
            overrides.font_size = number_value
            overrides.enable_tab_bar = false
        end
    end
    window:set_config_overrides(overrides)
end)

If you need this functionality within tmux, you need to add the following option to your tmux config:

set-option -g allow-passthrough on
