🗺️ AtlasWM

AtlasWM is a dynamic, customizable X11 window manager written in C, designed with flexibility and efficiency in mind. It provides a modern approach to window management while maintaining a lightweight footprint. (Not even 10MB of RAM and less than 0.1% of CPU!)

Features

• Dynamic Workspace Management: Support for multiple workspaces with customizable names
• Flexible Layouts: Multiple built-in layouts including:
  • Dwindle with gaps (default)
  • Floating
  • Full/Monocle
• Multi-Monitor Support: Full Xinerama support with intuitive monitor management
• Customizable Gaps: Both inner and outer gaps support through configuration
• Hot Reloading: Configuration can be reloaded without restarting the window manager
• IPC Support: Control AtlasWM through external commands
• Startup Programs: Automatically launch applications on startup
• Comprehensive Logging: Detailed logging system for debugging and monitoring

Dependencies

• Xlib (X11)
• Xft
• Xinerama

For Debian/Ubuntu:

sudo apt install libx11-dev libxft-dev libxinerama-dev libfontconfig1-dev

For Arch Linux:

sudo pacman -S libx11 libxft libxinerama fontconfig

Installation

1. Clone the repository:

git clone https://github.com/jasper-clarke/atlaswm.git
cd atlaswm

2. Build and install:

make
sudo make install

Configuration

AtlasWM uses TOML for configuration. Create a config file at ~/.config/atlaswm/config.toml:

See the example config file for a complete list of available options.

Key Bindings

Default key bindings can be customized in the config file. Available actions include:

• spawn: Launch applications
• killclient: Close the focused window
• reload: Reload AtlasWM configuration
• cyclefocus: Cycle through windows
• togglefloating: Toggle floating mode for windows
• focusmonitor: Focus different monitors
• movetomonitor: Move windows between monitors
• viewworkspace: View a specific workspace
• movetoworkspace: Move a window to a specific workspace
• duplicatetoworkspace: Duplicate a window to a specific workspace, this means you can have a single window on two workspaces (on the same monitor) at the same time!
• toggleworkspace: Toggle a workspace, this pulls the chosen workspace's windows onto the current workspace in a preview fashion (the windows are only visually there but still belong to the original workspace they came from)
• quit: Exit AtlasWM

Usage

1. Add to your .xinitrc:

exec atlaswm

2. Start X server:

startx

3. To reload configuration:

atlaswm reload

Debugging

AtlasWM maintains logs at ~/.atlaslogs. The log level can be configured in development, and logs include:

• INFO: General operation information
• WARNING: Non-critical issues
• ERROR: Critical issues that don't prevent operation
• DEBUG: Detailed debugging information
