A flexible and customizable QR code generator that allows you to create beautiful QR codes with different design styles.

• Multiple design styles: Google, Multicolored, and Custom
• Customizable text (title, subtitle, footer)
• Command-line interface for easy use
• Configuration file support
• Fallback font handling
• Proper error handling and logging

1. Install pipenv if you haven't already:

pip install pipenv

2. Clone the repository and navigate to it:

git clone <repository-url>
cd custom_qr

3. Install dependencies using pipenv:

pipenv install

4. Activate the virtual environment:

pipenv shell

If you prefer not to use pipenv, you can install dependencies directly:

pip install -r requirements.txt

Make sure you're in the virtual environment before running commands:

pipenv shell

Generate a QR code with the default design (custom):

# Inside pipenv shell
python main.py --url="https://example.com"

1. Google-style QR code:

# Inside pipenv shell
python main.py --url="https://example.com" \
               --design="google" \
               --title="Google" \
               --subtitle="Review" \
               --footer="TEAM <3"

2. Multicolored QR code:

# Inside pipenv shell
python main.py --url="https://www.linkedin.com/in/thomas-suau-92932889/" \
               --design="multicolored" \
               --title="My LinkedIn" \
               --subtitle="Review" \
               --footer="Thomas"

3. Custom QR code with gradient:

# Inside pipenv shell
python main.py --url="https://example.com" \
               --design="custom" \
               --title="Your Title" \
               --subtitle="Your Subtitle" \
               --footer="scan to visit example.com"

You can also use a JSON configuration file:

# Inside pipenv shell
python main.py --config="sample_config.json"

Example configuration file (sample_config.json):

{
    "url": "https://example.com",
    "design": "google",
    "output": "my_google_qr.png",
    "title": "My Company",
    "subtitle": "Visit Us",
    "footer": "TEAM <3"
}

The following arguments are available:

• --url: URL to encode in the QR code (required)
• --design: Design style for the QR code (choices: "google", "multicolored", "custom", default: "custom")
• --output: Output filename (will be saved in the outputs directory)
• --title: Title text for the QR code
• --subtitle: Subtitle text for the QR code
• --footer: Footer text for the QR code
• --config: Path to a configuration file

The generator uses custom fonts for better aesthetics. If the fonts are not available, it will fall back to the default system font.

Default font paths:

• fonts/CaviarDreams.ttf
• fonts/PatchworkStitchlings.ttf
• fonts/ORGANICAL.ttf

The application logs information and errors to both the console and a log file (qr_generator.log). This helps with debugging and tracking the generation process.

The application includes proper error handling for common issues:

• Invalid URLs
• Unsupported designs
• Missing configuration files
• Font loading errors
• File system errors
