    Waybar with Claude Code & Codex Usage Display

    This guide shows how to configure Waybar (for Wayland/Hyprland) with live status displays for Claude Code and Codex. The modules show current usage and rate limits in real-time in the status bar.

    📸 Example

    Waybar displays two modules:

    • CC (Claude Code): Shows 5h-block status with progress bar
    • COD (Codex): Shows rate-limit status with progress bar

    Example output:

    CC 🕐2h45m  67% ████████░  │  COD 🕐4h12m  23% ██░░░░░░
    

    🔧 Prerequisites

    System

    • Waybar (for Wayland/Hyprland)
    • Linux (Arch Linux, Ubuntu, etc.)
    • Bash Shell
    • jq (JSON Processor)

    Node.js Tools

    One of the following package managers:

    • npx (comes with Node.js)
    • bunx (Bun)
    • pnpm

    Claude Code & Codex Tools

    • ccusage: npm install -g ccusage or via npx ccusage
    • @ccusage/codex: npm install -g @ccusage/codex or via npx @ccusage/codex

    📁 File Structure

    ~/.config/waybar/
    ├── config.jsonc              # Waybar main configuration
    ├── style.css                 # Waybar styling
    └── scripts/
        ├── ccusage-statusline.sh    # Claude Code status script
        ├── codex-statusline.sh      # Codex status script
        └── api-config.sh (optional) # API configuration
    

    📝 Step 1: Waybar Configuration

    Open ~/.config/waybar/config.jsonc and add the two modules:

    1.1 Add modules to modules-center

    {
      "modules-center": [
        // ... other modules ...
        "custom/ccusage",
        "custom/codex-usage",
        // ... other modules ...
      ],
    
      // ... rest of config ...
    
      "custom/ccusage": {
        "exec": "~/.config/waybar/scripts/ccusage-statusline.sh",
        "interval": 300,
        "format": "{}",
        "tooltip-format": "ccusage daily + monthly totals (Claude Code)\nClick to refresh",
        "on-click": "~/.config/waybar/scripts/ccusage-statusline.sh"
      },
    
      "custom/codex-usage": {
        "exec": "~/.config/waybar/scripts/codex-statusline.sh",
        "interval": 300,
        "format": "{}",
        "tooltip-format": "ccusage codex daily + monthly totals\nClick to refresh",
        "on-click": "~/.config/waybar/scripts/codex-statusline.sh"
      }
    }
    

    Explanation:

    • exec: Path to the script that provides the data
    • interval: Update interval in seconds (300s = 5min)
    • format: Display format (here directly the script output)
    • on-click: Clicking triggers a manual script update

    📝 Step 2: Waybar Styling

    Add the styling for the modules in ~/.config/waybar/style.css:

    #custom-ccusage {
      background-color: rgba(40, 42, 54, 0.8);
      padding: 4px 10px;
      margin: 2px 4px;
      border-radius: 8px;
      font-family: 'JetBrainsMono Nerd Font Mono';
      font-size: 11px;
      color: #ff6ac1;  /* Pink for Claude Code */
    }
    
    #custom-codex-usage {
      background-color: rgba(40, 42, 54, 0.8);
      padding: 4px 10px;
      margin: 2px 4px;
      border-radius: 8px;
      font-family: 'JetBrainsMono Nerd Font Mono';
      font-size: 11px;
      color: #6ef2d0;  /* Turquoise for Codex */
    }
    

    Customizations:

    • color: Text color (can be changed as desired)
    • font-family: Nerd Font for icons (install JetBrainsMono Nerd Font)
    • font-size: Adjust font size

    📝 Step 3: Create Scripts

    3.1 Create script directory

    mkdir -p ~/.config/waybar/scripts
    chmod +x ~/.config/waybar/scripts/*.sh
    

    3.2 Claude Code Script

    Create ~/.config/waybar/scripts/ccusage-statusline.sh:

  • The longest officially used German word was:

    Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz

    (63 letters)

    Translation:

    “Beef labeling monitoring delegation law”

    This was the name of a law in the German state of Mecklenburg-Vorpommern. It referred to the delegation of tasks related to monitoring beef labeling, especially relevant during the BSE (mad cow disease) crisis. The law was abolished in 2013.


    But German allows theoretically endless compound words. A classic (but not officially used) example is:

    Donaudampfschifffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft

    (80 letters)

    Translation:

    “Association of subordinate officials of the main building for electrical services of the Danube steamship company”

    This is a joke word created to illustrate how German compounds work. It’s not used in real life, but it’s popular in linguistic discussions and trivia.
