Basic Configuration

Configuration File

mangowm uses a simple configuration file format. By default, it looks for a configuration file in ~/.config/mango/.

1. Locate Default Config

   A fallback configuration is provided at /etc/mango/config.conf. You can use this as a reference.

2. Create User Config

   Copy the default config to your local config directory to start customizing.

   mkdir -p ~/.config/mango
   cp /etc/mango/config.conf ~/.config/mango/config.conf

3. Launch with Custom Config (Optional)

   If you prefer to keep your config elsewhere, you can launch mango with the -c flag.

   mango -c /path/to/your_config.conf

TOML Format

mangowm also reads TOML config files. When looking for a user config, ~/.config/mango/config.conf is preferred, then ~/.config/mango/config.toml (likewise under /etc/mango/).

See TOML Conversion for the syntax and how to convert an existing conf file.

Sub-Configuration

To keep your configuration organized, you can split it into multiple files and include them using the source keyword.

# Import keybindings from a separate file
source=~/.config/mango/bind.conf

# Relative paths work too
source=./theme.conf

# Optional: ignore if file doesn't exist (useful for shared configs)
source_optional=~/.config/mango/optional.conf

Validate Configuration

You can check your configuration for errors without starting mangowm:

mango -c /path/to/config.conf -p

Use with source_optional for shared configs across different setups.

Environment Variables

You can define environment variables directly within your config file. These are set before the window manager fully initializes.

Warning: Environment variables defined here will be reset every time you reload the configuration.

env=QT_IM_MODULES,wayland;fcitx
env=XMODIFIERS,@im=fcitx

Configuration Variables

You can define your own variables and reuse them anywhere in the config. A variable is defined with var=name,value and referenced with $name or ${name}. Names must start with a letter or _, followed by letters, digits, or _.

var=term,kitty
var=editor,nvim
var=screenshot_dir,~/Pictures/Screenshots

bind=SUPER,Return,spawn,$term
bind=SUPER,E,spawn,$term -e $editor
bind=SUPER,Print,spawn_shell,grim ${screenshot_dir}/$(date +%Y%m%d%H%M%S).png

Variables must be defined before they are used, and they are shared across source/source_optional files (the included file can use variables defined before the source line).

Note: Only names you actually defined are expanded. Anything else is left untouched, so shell commands keep working exactly as before:

# $HOME, $(date ...), $1 and $$ are not config variables here,
# so the shell still receives them verbatim.
bind=SUPER,P,spawn_shell,echo "$HOME" | rofi -dmenu

Defining a variable with the same name as a shell variable you use in a spawn_shell command will cause mango to expand it first. Prefer distinctive names to avoid surprises.

Autostart

mangowm can automatically run commands or scripts upon startup. There are two modes for execution:

Example Setup

# Start the status bar once
exec_once=waybar

# Set wallpaper
exec_once=swaybg -i ~/.config/mango/wallpaper/room.png

# Reload a custom script on config change
exec=bash ~/.config/mango/reload-settings.sh
