AI Integration

+

+ Control your desktop with natural language and get intelligent assistance. +

+
+
+ +
+
+
+ Optional Features +

AI features are completely optional and require external API keys. + DWN works perfectly without them.

+
+ +

Overview

+

+ DWN integrates with two AI services to provide intelligent desktop assistance: +

+
    +
  • OpenRouter API - Powers the AI command palette and context analysis
    • +
  • Exa API - Provides semantic web search capabilities
    • +
+ +
+
+
🤖
+

AI Command Palette

+

Type natural language commands to control your desktop. + Launch apps, query system info, and more.

+

Super + Shift + A

+
+
+
👁
+

Context Analysis

+

AI analyzes your current workspace to understand your task + and provide relevant suggestions.

+

Super + A

+
+
+
🔍
+

Semantic Search

+

Search the web using meaning, not just keywords. + Find relevant content instantly.

+

Super + Shift + E

+
+
+ + +

Setting Up OpenRouter

+

+ OpenRouter provides access to multiple AI models through a single API. + You can use free models or paid ones depending on your needs. +

+ +
+
+
1
+
+

Get an API Key

+

Visit https://openrouter.ai/keys + and create a free account to get your API key.

+
+
+ +
+
2
+
+

Set the Environment Variable

+

Add to your shell profile (~/.bashrc, ~/.zshrc, etc.):

+
+ ~/.bashrc + +
+ 
export OPENROUTER_API_KEY="sk-or-v1-your-key-here"
+
+
+ +
+
3
+
+

Choose a Model (Optional)

+

Configure the AI model in your DWN config file:

+
+ ~/.config/dwn/config + +
+ 
[ai]
+model = google/gemini-2.0-flash-exp:free
+

+ Browse available models at openrouter.ai/models +

+
+
+
+ +
+

Recommended Free Models

+
+ + + + + + + + + + + + + + + + + + + + + + + + + +
Model IDProviderBest For
google/gemini-2.0-flash-exp:freeGoogleFast responses, good general use
meta-llama/llama-3.2-3b-instruct:freeMetaQuick commands, lightweight
mistralai/mistral-7b-instruct:freeMistralBalanced performance
+
+
+ + +

AI Command Palette

+

+ Press Super + Shift + A to open the command palette. + Type natural language commands and press Enter. +

+ +

Supported Commands

+
+ + + + + + + + + + + + + + + + + + + + + +
CategoryExamples
Launch Applications + "open firefox"
+ "run terminal"
+ "launch file manager"
+ "start chrome" +
System Queries + "what time is it"
+ "how much memory is free"
+ "what's my IP address"
+ "show disk usage" +
General Questions + "how do I resize the master area"
+ "what's the shortcut for fullscreen"
+ "explain tiling mode" +
+
+ +
+ Pro Tip +

The AI understands context. You can say "open browser" instead of + remembering the exact application name - it will figure out what you mean.

+
+ + +

Context Analysis

+

+ Press Super + A to see AI-powered analysis of your current workspace. +

+ +
+

What It Shows

+
    +
  • Task Type - Coding, browsing, communication, etc.
    • +
  • Focused Window - Currently active application
    • +
  • Suggestions - Relevant shortcuts or actions based on context
    • +
  • Workspace Summary - Overview of open applications
    • +
+
+ + +

Setting Up Exa Search

+

+ Exa provides semantic search - finding content based on meaning rather than exact keywords. +

+ +
+
+
1
+
+

Get an Exa API Key

+

Visit https://dashboard.exa.ai/api-keys + and create an account to get your API key.

+
+
+ +
+
2
+
+

Set the Environment Variable

+
+ ~/.bashrc + +
+ 
export EXA_API_KEY="your-exa-key-here"
+
+
+ +
+
3
+
+

Start Searching

+

Press Super + Shift + E and type your query.

+
+
+
+ + + +

+ Unlike traditional search, Exa understands the meaning of your query. +

+ +
+
+

Traditional Search

+

Keyword matching

+
    +
  • Exact keyword matches
    • +
  • Boolean operators needed
    • +
  • Miss relevant results
    • +
+

+ "nginx reverse proxy setup tutorial" +

+
+
+

Semantic Search

+

Meaning-based

+
    +
  • Understands intent
    • +
  • Natural language
    • +
  • Finds related content
    • +
+

+ "how to configure nginx as a reverse proxy" +

+
+
+ +

Search Tips

+
    +
  • Use natural, conversational queries
    • +
  • Be specific about what you're looking for
    • +
  • Results appear in a dmenu/rofi list - select to open in browser
    • +
  • Search includes articles, documentation, tutorials, and more
    • +
+ + +

Privacy Considerations

+
+ Data Sent to External Services +

When using AI features, the following data is sent to external APIs:

+
+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + +
FeatureData SentService
Command PaletteYour typed commandOpenRouter (then to model provider)
Context AnalysisWindow titles, app namesOpenRouter (then to model provider)
Semantic SearchYour search queryExa
+
+ +

+ If you're concerned about privacy, you can: +

+
    +
  • Not configure API keys (AI features simply won't work)
    • +
  • Use OpenRouter with privacy-focused models
    • +
  • Only use AI features when needed
    • +
+ + +

Troubleshooting

+ +
+ +
+
+

Make sure your API key is properly set:

+
    +
  1. Check the environment variable: echo $OPENROUTER_API_KEY
    2. +
  2. Ensure the variable is exported in your shell profile
    3. +
  3. Log out and back in, or source your profile: source ~/.bashrc
    4. +
  4. Restart DWN
    5. +
+
+
+
+ +
+ +
+
+

Try using a faster model. Free models can sometimes be slow due to rate limiting. + Gemini Flash is usually the fastest free option.

+
+
+
+ +
+ +
+
+

Check your Exa API key and ensure you have remaining credits. + Visit the Exa dashboard to check your usage.

Global State (DWNState)

+

+ All window manager state is centralized in a single DWNState structure. + This simplifies state management and makes the codebase easier to understand. +

+ +
+ include/dwn.h (simplified) +
+ 
typedef struct {
+    Display *display;           // X11 connection
+    Window root;                // Root window
+    int screen;                 // Default screen
+
+    Client *clients[MAX_CLIENTS];   // All managed windows
+    int client_count;
+
+    Workspace workspaces[MAX_WORKSPACES];  // Virtual desktops
+    int current_workspace;
+
+    Panel top_panel;
+    Panel bottom_panel;
+
+    Config config;              // User configuration
+    KeyBinding keys[MAX_KEYBINDINGS];
+
+    // EWMH atoms
+    Atom atoms[ATOM_COUNT];
+} DWNState;
+
+extern DWNState *dwn;  // Global singleton
+ + +

Event Loop

+

+ DWN uses a traditional X11 event loop with XNextEvent. Events are dispatched + to appropriate handlers based on type. +

+ +
+ main.c (simplified) +
+ 
int main(int argc, char *argv[]) {
+    dwn_init();           // Initialize X11, atoms, config
+    setup_keybindings();  // Register keyboard shortcuts
+    setup_panels();       // Create panel windows
+
+    XEvent event;
+    while (running) {
+        XNextEvent(dwn->display, &event);
+
+        switch (event.type) {
+            case MapRequest:
+                handle_map_request(&event.xmaprequest);
+                break;
+            case UnmapNotify:
+                handle_unmap_notify(&event.xunmap);
+                break;
+            case KeyPress:
+                handle_key_press(&event.xkey);
+                break;
+            case ButtonPress:
+                handle_button_press(&event.xbutton);
+                break;
+            case ConfigureRequest:
+                handle_configure_request(&event.xconfigurerequest);
+                break;
+            // ... more event types
+        }
+    }
+
+    dwn_cleanup();
+    return 0;
+}

Coding Conventions

+
+
+

Naming

+
    +
  • snake_case for functions and variables
    • +
  • CamelCase for types and structs
    • +
  • Module prefix for functions (e.g., client_focus())
    • +
  • Constants in UPPER_SNAKE_CASE
    • +
+
+
+

Style

+
    +
  • 4-space indentation
    • +
  • K&R brace style
    • +
  • Max 100 characters per line
    • +
  • clang-format for consistency
    • +
+
+
+ +
+ Example Function +
+ 
void client_focus(Client *c) {
+    if (!c) return;
+
+    // Unfocus previous
+    if (dwn->focused && dwn->focused != c) {
+        client_unfocus(dwn->focused);
+    }
+
+    dwn->focused = c;
+    XSetInputFocus(dwn->display, c->window, RevertToPointerRoot, CurrentTime);
+    XRaiseWindow(dwn->display, c->frame);
+
+    decorations_update(c);
+    atoms_set_active_window(c->window);

Configuration Guide

+

+ Customize every aspect of DWN to match your workflow and style. +

+
+
+ +
+
+

Configuration File

+

+ DWN reads its configuration from ~/.config/dwn/config using an INI-style format. + Changes take effect on restart (or you can reload in a future version). +

+ +
+ First Run +

DWN creates a default configuration file on first run if one doesn't exist. + You can also copy the example config from the source repository.

Getting Started with DWN

+

+ Learn the fundamentals of DWN and become productive in minutes. +

+ +

First Steps

+

+ After installing DWN and starting your session, + you'll see a clean desktop with two panels: a top panel with workspace indicators, + taskbar, and system tray, and a bottom panel showing the clock. +

+ +

Opening Your First Application

+

Start by launching a terminal and application launcher:

+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + +
ShortcutAction
Ctrl + Alt + TOpen terminal
Alt + F2Open application launcher (dmenu/rofi)
Super + EOpen file manager
Super + BOpen web browser
+
+ +
+ Tip: Run the Tutorial +

Press Super + T to start an interactive + tutorial that will guide you through all essential shortcuts.

+
+ +

Basic Concepts

+ +

The Super Key

+

+ Most DWN shortcuts use the Super key (often the Windows key or Command key). + This keeps shortcuts separate from application shortcuts that typically use + Ctrl or Alt. +

+ +

Focus Model

+

+ By default, DWN uses "click to focus" - you click on a window to focus it. + You can change this to "focus follows mouse" (sloppy focus) in the configuration. +

+ +

Window Decorations

+

+ Each window has a title bar showing its name. The title bar color indicates focus: +

+
    +
  • Blue title bar - Focused window
    • +
  • Gray title bar - Unfocused window
    • +
+ +

Interactive Tutorial

+

+ DWN includes a built-in interactive tutorial that teaches you essential shortcuts + step by step. The tutorial: +

+
    +
  • Shows instructions for each shortcut
    • +
  • Waits for you to press the correct keys
    • +
  • Automatically advances when you complete each step
    • +
  • Covers all essential shortcuts from basic to advanced
    • +
+ +
+

Start the Tutorial

+

Press Super + T at any time to start or resume the tutorial.

+
+ +

  • Move - Click and drag the title bar
    • +
  • Resize - Drag any window edge or corner

Session Setup

+

+ Configure your display manager or xinit to start DWN. +

+ +
+
+

Using xinit / startx

+

For minimal setups using startx:

+
+ ~/.xinitrc + +
+ 
# Optional: set display settings
+xrandr --output DP-1 --mode 2560x1440
+
+# Optional: set wallpaper
+feh --bg-fill ~/wallpaper.jpg
+
+# Start DWN
+exec dwn
+

+ Then run startx from a TTY. +

+
+
+

Using a Display Manager

+

Create a desktop entry for GDM, LightDM, etc:

+
+ /usr/share/xsessions/dwn.desktop + +
+ 
[Desktop Entry]
+Name=DWN
+Comment=DWN Window Manager
+Exec=dwn
+Type=Application
+DesktopNames=DWN
+

+ DWN will appear in your display manager's session menu. +

+
+
+
+
+ + +
+
+

Testing in a Nested X Server

+

+ Test DWN without leaving your current session using Xephyr. +

+ +
+

Using make run

+

The easiest way to test DWN safely:

+
+ Terminal + +
+ 
# Make sure Xephyr is installed
+# Debian/Ubuntu: sudo apt install xserver-xephyr
+# Fedora: sudo dnf install xorg-x11-server-Xephyr
+# Arch: sudo pacman -S xorg-server-xephyr
+
+# Run DWN in a nested window
+make run
+

+ This opens a 1280x720 window running DWN. Perfect for experimenting with configuration changes. +

+
+ +
+

Manual Xephyr Setup

+

For more control over the test environment:

+
+ Terminal + +
+ 
# Start Xephyr on display :1
+Xephyr :1 -screen 1920x1080 &
+
+# Run DWN on that display
+DISPLAY=:1 ./dwn
+
+# Open a terminal in the test environment
+DISPLAY=:1 xterm &
+
+
+
+ + +
+
+

Post-Installation

+ +
+
+

+
+

Create Configuration Directory

+

DWN will create this automatically on first run, but you can set it up in advance:

+
+ Terminal + +
+ 
mkdir -p ~/.config/dwn
+
+
+ +
+

+

+
+

Customize Your Setup

+

See the Configuration Guide to personalize DWN to your liking.

+
+
+
+
+
+ + +
+
+

Troubleshooting

+ +
+ +
+
+

This error means DWN can't connect to an X server. Make sure:

+
    +
  • You're running from a TTY with startx, not from within another X session
    • +
  • The DISPLAY environment variable is set correctly
    • +
  • X server is installed and working (Xorg -configure to test)
    • +
+
+
+
+ +
+ +
+
+

Install pkg-config for your distribution:

+ 
sudo apt install pkg-config    # Debian/Ubuntu
+sudo dnf install pkg-config    # Fedora
+sudo pacman -S pkg-config      # Arch
+
+
+
+ +
+ +
+
+

Make sure you have the development packages installed, not just the runtime libraries. + On Debian/Ubuntu, install packages ending with -dev. + Run make deps to auto-install everything.

+
+
+
+ +
+ +
+
+

Check for conflicts with other programs grabbing keys:

+
    +
  • Make sure no other window manager is running
    • +
  • Check if compositor (like picom) is grabbing keys
    • +
  • Verify keyboard layout is correct with setxkbmap
    • +
+
+
+
+ +
+ +
+
+

DWN uses Xft for font rendering. Install some good fonts:

+ 
sudo apt install fonts-dejavu fonts-liberation  # Debian/Ubuntu
+sudo dnf install dejavu-fonts-all liberation-fonts  # Fedora
+

You can configure the font in ~/.config/dwn/config.
