* OXWM — DWM but Better (and oxidized)

A dynamic window manager written in Rust, inspired by dwm but designed to evolve

on its own. Configuration is done in Rust source code, keeping with the suckless

philosophy of *"edit + recompile."*, but with sane defaults and no arbitrary elitism

enforcing bad variable names and bad file structure topology.

* Installation

** NixOS (with Flakes)

*** Adding OXWM to your flake inputs

Add oxwm to your =flake.nix= inputs:

#+begin_src nix

{

  inputs = {

    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    oxwm.url = "github:tonybanters/oxwm";

    oxwm.inputs.nixpkgs.follows = "nixpkgs";

  };

  outputs = { self, nixpkgs, oxwm, ... }: {

    nixosConfigurations.yourhost = nixpkgs.lib.nixosSystem {

      system = "x86_64-linux";

      modules = [

        ./configuration.nix

        oxwm.nixosModules.default

      ];

    };

  };

}

#+end_src

*** Enabling OXWM in configuration.nix

Add this to your =configuration.nix=:

#+begin_src nix

{ config, pkgs, ... }:

{

  services.xserver = {

    enable = true;

    windowManager.oxwm.enable = true;

  };

  # Recommended: Install a display manager

  services.xserver.displayManager.lightdm.enable = true;

  # Or use another display manager like sddm, gdm, etc.

}

#+end_src

*** 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.ron=. Edit it and reload with =Mod+Shift+R=.

*** Advanced: Using a specific oxwm version

If you want to pin or customize the oxwm package:

#+begin_src nix

{

  services.xserver.windowManager.oxwm = {

    enable = true;

    # Use a specific version or build with custom options

    package = oxwm.packages.${pkgs.system}.default;

  };

}

#+end_src

*** Development setup with Nix

For development, use the provided dev shell:

#+begin_src sh

# Clone the repository

git clone https://github.com/tonybanters/oxwm

cd oxwm

# Enter the development environment

nix develop

# Build and test

cargo build

just test

#+end_src

** Arch Linux

Install dependencies:

#+begin_src sh

sudo pacman -S rust cargo libx11 libxft freetype2 fontconfig pkg-config

#+end_src

** Building from Source

#+begin_src sh

git clone https://github.com/tonybanters/oxwm

cd oxwm

cargo build --release

sudo cp target/release/oxwm /usr/local/bin/

#+end_src

Or use the justfile:

#+begin_src sh

just install

#+end_src

** Setting up OXWM

*** Without a display manager (startx)

Add the following to your =~/.xinitrc=:

#+begin_src sh

exec oxwm

#+end_src

Then start X with:

#+begin_src sh

startx

#+end_src

*** With a display manager

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

* Configuration

OXWM was inspired by dwm, but ditched the suckless philosophy. This philosophy quite literally discourages users from using the software for the sake of 'elitism'. I find that quite nonsensical, so I went ahead and created this project to be user friendly. The configuration is done by editing =~/.config/oxwm/config.ron= and the binary can be reloaded with a hotkey (Super+Shift+R by efault).

Edit =~/.config/oxwm/config.ron= to customize:

- Keybindings

- Colors and appearance

- Status bar blocks

- Gaps and borders

- Terminal and applications

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

* Contributing

When contributing to OXWM:

1. Never commit your personal =~/.config/oxwm/config.ron=

2. Only modify =templates/config.ron= if adding new configuration options

3. Test your changes with =just test= using Xephyr/Xwayland

4. Document any new features or keybindings

* Key Bindings

Default keybindings (customizable in config.rs):

| Binding           | Action                  |

|-------------------+-------------------------|

| Super+Return      | Spawn terminal          |

| Super+J/K         | Cycle focus down/up     |

| Super+Q           | Kill focused window     |

| Super+Shift+Q     | Quit WM                 |

| Super+Shift+R     | Hot reload WM           |

| Super+1-9         | View tag 1-9            |

| Super+Shift+1-9   | Move window to tag 1-9  |

| Super+S           | Screenshot (maim)       |

| Super+D           | dmenu launcher          |

| Super+A           | Toggle gaps             |

| Super+Shift+F     | Toggle fullscreen       |

| Super+Shift+Space | Toggle floating         |

* Features

- Dynamic tiling layout with master/stack

- Tag-based workspaces (9 tags by default)

- Configurable gaps between windows

- Status bar with modular block system

  - Battery, RAM, datetime, shell commands

  - Custom colors and update intervals

  - Click-to-switch tags

- Window focus cycling

- Hot reload without restarting X

- Persistent window tags across restarts

- Mouse hover to focus

- Border indicators for focused windows

- Fullscreen mode

* Testing with Xephyr

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

#+begin_src sh

just test

#+end_src

This starts Xephyr on display :1 and launches OXWM inside it.

Or manually:

#+begin_src sh

Xephyr -screen 1280x800 :1 &

DISPLAY=:1 cargo run

#+end_src

* Project Structure

#+begin_src sh

* Architecture Notes

** Tag System

Tags are implemented as bitmasks (TagMask = u32), allowing windows to belong to multiple tags simultaneously. Each window has an associated TagMask stored in a HashMap. Tags persist across WM restarts using X11 properties (_NET_CURRENT_DESKTOP for selected tags, _NET_CLIENT_INFO for per-window tags).

** Status Bar

The bar uses a performance-optimized approach with a modular block system:

- Only redraws when invalidated

- Pre-calculates tag widths on creation

- Blocks update independently based on their configured intervals

- Supports custom colors and underline indicators

- Easily extensible - add new block types in src/bar/blocks/

** Layout System

The tiling layout divides the screen into a master area (left half) and stack area (right half). The master window occupies the full height of the master area, while stack windows split the stack area vertically. Gaps are configurable and can be toggled at runtime.

* TODO Current Todo List:

** PRIORITY High [0/2]

- [ ] Convert keycodes to keysyms for cross-keyboard compatibility

  - Current hardcoded keycodes only work on specific keyboards

  - Need to use XKeysymToKeycode() for runtime conversion

  - Follow DWM's approach: keysym → keycode conversion

- [ ] Fix fullscreen to persist across tags

  - Fullscreen state should be maintained when switching tags

  - Window should remain fullscreen when returning to its tag

** PRIORITY Medium [0/3]

- [ ] Add keybindings to increase/decrease window size

  - Master area resize (Mod+H / Mod+L)

  - Individual window resize for floating windows

- [ ] Fix cursor on hover for bar

  - Bar should show pointer cursor on hover

  - Indicate clickable tag areas

- [ ] Add guess_terminal() function to default config.rs

  - Auto-detect available terminal emulator

  - Priority order: st → alacritty → kitty → wezterm → xterm

  - Fallback to xterm if none found

** PRIORITY Low [0/1]

- [ ] Create AUR package

  - Write PKGBUILD

  - Submit to AUR

  - Add installation instructions to README

* Development Roadmap

** Current Focus

- Multi-monitor support

- Additional layouts (monocle, floating)

- Master area resizing

- Window swapping in layout

** Future Enhancements

- Per-window floating behavior

- Per-program rules (auto-tag assignment, floating rules)

- External bar support (polybar, lemonbar)

- Scratchpad functionality

- Window minimize/restore
