🚀 Installation

Prerequisites

• Python 3.8 or higher
• Chrome browser (automatically managed by webdriver-manager)
• uv package manager (recommended for best experience)

Setup

1. Clone the repository:

   git clone https://github.com/al-chris/pahe-downloader.git
   cd pahe-downloader

2. Install dependencies using uv (recommended):

   uv sync

   Or using pip:

   pip install -e .

3. No manual driver setup required: webdriver-manager automatically downloads and manages Chrome drivers for your system, caching them in your AppData folder.

🎯 Usage

1. Start the application:

   uv run main.py

   Or:

   python main.py

2. Desktop window opens automatically: The application will open in a native desktop window powered by PyWebView.

3. Enter anime URL:

   • Copy the full URL from animepahe.si, animepahe.ru, animepahe.com, or other AnimePahe domains
   • The URL field validates input and provides visual feedback
   • Make sure the URL contains "/anime/" in the path

4. Select episodes:

   • View all available episodes in a beautiful grid layout
   • Episodes are pre-selected by default
   • Click individual episodes or use "Select All" to toggle selection
   • Use Ctrl+A keyboard shortcut for quick selection

5. Download:

   • Click "📥 Download Selected Episodes"
   • Monitor real-time progress on the download page
   • Files are saved to the downloads/ folder with proper naming
   • Check logs at %LOCALAPPDATA%/pahe-downloader/logs/app.log if issues occur

🎨 UI Features

Homepage

• Gradient background with anime-themed styling
• Clean form with URL validation
• Helpful usage instructions
• Responsive design for all screen sizes

Episode Selection

• Card-based layout for easy episode browsing
• Visual selection states with smooth animations
• Episode count display
• Bulk selection controls

Download Progress

• Real-time progress bar
• Status messages throughout the process
• Files saved to downloads/ folder with intelligent naming
• Automatic extension detection for proper file types

📁 File Naming & Organization

Downloads are automatically organized with descriptive filenames:

• Format: {AnimeName}_Episode_{Number}.{extension}
• Examples:
  • One Piece_Episode_1.mp4
  • Attack on Titan_Episode_25.mkv
  • My Hero Academia_Episode_10.mp4
• Features:
  • Anime name extracted from webpage title
  • Invalid characters automatically sanitized
  • Correct file extensions detected from server headers
  • Supports MP4, MKV, AVI, MOV, WMV, FLV, and WebM formats

🔧 How It Works

1. URL Processing: Extracts anime ID and title from the provided URL
2. Episode Discovery: Uses Selenium to scrape episode information and anime title
3. Link Resolution: Bypasses DDoS-Guard and resolves download links
4. Extension Detection: Analyzes HTTP headers to determine correct file extensions
5. Intelligent Naming: Creates filenames with anime title, episode number, and proper extension
6. Concurrent Downloads: Downloads multiple episodes simultaneously to downloads/ folder
7. Progress Tracking: Real-time updates through the desktop interface

📋 Logging & Debugging

The application includes comprehensive logging for troubleshooting:

Log Location

• File: %LOCALAPPDATA%/pahe-downloader/logs/app.log
• Console: INFO level messages appear in the console during development
• Levels: DEBUG, INFO, WARNING, ERROR with timestamps

What Gets Logged

• Browser driver initialization and management
• Web scraping operations and results
• Download progress and file operations
• Error conditions and exceptions
• Episode parsing and URL resolution

Troubleshooting

If you encounter issues:

1. Check the log file at %LOCALAPPDATA%/pahe-downloader/logs/app.log
2. Look for ERROR or WARNING messages
3. The logs include detailed information about failures and their causes
4. For driver issues, logs will show Chrome version detection and driver download status

Driver Management

• Chrome drivers are automatically downloaded and cached in %LOCALAPPDATA%/pahe-downloader/webdrivers/
• Drivers are reused across sessions when compatible
• Automatic redownload occurs if Chrome version changes or cache is corrupted

📦 Distribution

Building Standalone Executable

To create a single executable file for easy distribution:

Option 1: Using the Build Script (Recommended)

# Install PyInstaller in the project environment
uv pip install pyinstaller

# Run the build script
uv run build.py

Option 2: Manual PyInstaller Command

# Install PyInstaller
uv pip install pyinstaller

# Build the executable with custom icon
uv run pyinstaller --onefile --hidden-import=webdriver_manager --hidden-import=selenium --hidden-import=webview --hidden-import=webview.platforms.winforms --hidden-import=clr --hidden-import=pythonnet --hidden-import=flask --hidden-import=beautifulsoup4 --hidden-import=lxml --hidden-import=requests --hidden-import=urllib3 --name=pahe-downloader --clean --noconsole --icon=static/icon.ico main.py

The executable will be created in the dist/ folder as pahe-downloader.exe with the custom application icon.

Automated Releases

When you create a new release on GitHub, the CI/CD pipeline will automatically:

1. Build the executable using PyInstaller
2. Generate a SHA256 checksum for verification
3. Upload both files as release assets

Users can then download the standalone executable and run it without installing Python or any dependencies.

GitHub Releases

The project includes automated CI/CD that builds releases:

• Trigger: Creating a new release on GitHub automatically starts the build process
• Platform: Windows executables (built on windows-latest runners)
• Artifacts:
  • pahe-downloader.exe - The standalone executable with custom icon
  • pahe-downloader.exe.sha256 - SHA256 checksum for verification
• Manual Trigger: You can also trigger builds manually using the "Run workflow" button
