OXWM: DWM but Better

A dynamic window manager written in Zig, inspired by dwm but designed to evolve beyond it. OXWM features a clean, functional Lua API for configuration with hot-reloading support, ditching the suckless philosophy of "edit + recompile". Instead, we focus on lowering friction for users with sane defaults, LSP-powered autocomplete, and instant configuration changes without restarting your X session.

Documentation: ox-docs.vercel.app

Showcase

Setups from OXWM users across Arch, CachyOS, Debian and FreeBSD.

Installation

NixOS (nixpkgs)

Add OXWM to your configuration.nix like so:

{ config, pkgs, ... }:

{
  services.xserver.windowManager.oxwm.enable = true;
}

Initialize your config

After rebuilding your system with sudo nixos-rebuild switch, log in via your display manager.

On first launch, your initial config file will be automatically created and placed in ~/.config/oxwm/config.lua. Edit it and reload with Mod+Shift+R.

Development setup with Nix

For development, use the provided dev shell:

# Clone the repository
git clone https://github.com/tonybanters/oxwm
cd oxwm

# Enter the development environment
nix develop

# Build and test
zig build -Doptimize=ReleaseSmall

Arch Linux

AUR: oxwm-git

yay -S oxwm-git

This will automatically put a desktop session file into your xsessions directory.

Manually, install the dependencies and see Building from Source:

sudo pacman -S zig libx11 libxft freetype2 fontconfig libxinerama

Building from Source

Note, on many BSD systems, the zig compiler will aggressively attempt to remove debug symbols which is causing a known linker issue. Please use this method on BSD:

git clone https://github.com/tonybanters/oxwm
cd oxwm
zig build

On other legacy distros, just use:

git clone https://github.com/tonybanters/oxwm
cd oxwm
zig build -Doptimize=ReleaseSmall --prefix /usr

Setting up OXWM

Without a display manager (startx)

Add the following to your ~/.xinitrc:

exec oxwm

Then start X with:

startx

With a display manager

If using a display manager (LightDM, GDM, SDDM), OXWM should appear in the session list after installation.

Configuration

OXWM uses a clean, functional Lua API for configuration. On first run, a default config is automatically created at ~/.config/oxwm/config.lua.

Quick Example

Here's what the functional API looks like:

-- Set basic options
oxwm.set_terminal("st")
oxwm.set_modkey("Mod4")
oxwm.set_tags({ "1", "2", "3", "4", "5", "6", "7", "8", "9" })

-- Configure borders
oxwm.border.set_width(2)
oxwm.border.set_focused_color("#6dade3")
oxwm.border.set_unfocused_color("#bbbbbb")

-- Configure gaps
oxwm.gaps.set_enabled(true)
oxwm.gaps.set_inner(5, 5)  -- horizontal, vertical
oxwm.gaps.set_outer(5, 5)

-- Set up keybindings
oxwm.key.bind({ "Mod4" }, "Return", oxwm.spawn("st"))
oxwm.key.bind({ "Mod4" }, "Q", oxwm.client.kill())
oxwm.key.bind({ "Mod4", "Shift" }, "Q", oxwm.quit())

-- Add status bar blocks
oxwm.bar.set_blocks({
    oxwm.bar.block.datetime({
        format = "{}",
        date_format = "%H:%M",
        interval = 60,
        color = "#0db9d7",
        underline = true,
    }),
    oxwm.bar.block.ram({
        format = "RAM: {used}/{total} GB",
        interval = 5,
        color = "#7aa2f7",
        underline = true,
    }),
})

Key Configuration Areas

Edit ~/.config/oxwm/config.lua to customize:

• Basic settings (terminal, modkey, tags)
• Borders and colors
• Window gaps
• Status bar (font, blocks, color schemes)
• Keybindings and keychords
• Layouts, layout symbols, and attach method
• Window rules
• Autostart commands

After making changes, reload OXWM with Mod+Shift+R.

Creating Your Config

Generate the default config:

oxwm --init

Or just start OXWM. It will create one automatically on first run.

Contributing

When contributing to OXWM:

1. Never commit your personal ~/.config/oxwm/config.lua
2. Only modify templates/config.lua if adding new configuration options
3. Test your changes with zig build xephyr using Xephyr or zig build xwayland using Xwayland
4. Document any new features or keybindings

Super+A	Toggle gaps
Super+Shift+F	Toggle fullscreen
Super+Shift+Space	Toggle floating

Super+N	Cycle layouts
Super+Comma/Period	Focus prev/next monitor
Super+Shift+Comma/.	Send window to prev/next monitor
Super+[/]	Decrease/increase master area

Testing with Xephyr

Test OXWM in a nested X server without affecting your current session:

zig build xephyr

This starts Xephyr on display :2 and launches OXWM inside it.

For multi-monitor testing:

zig build xephyr-multi

Or manually:

Xephyr -screen 1280x800 :2 &
DISPLAY=:2 zig build run
