ASCII Art Examples

ASCII art is a signature feature of pretty-loguru, capable of creating impressive text art titles. This page showcases various practical applications of ASCII art.

🎯 Basic ASCII Headers

Application Startup Header

from pretty_loguru import create_logger

# Initialize the logging system
logger = create_logger(
    name="ascii-art_demo",
    log_path="ascii_demo",
    level="INFO"
)

# Application startup
logger.ascii_header("APP START", font="slant", border_style="blue")
logger.info("Loading configuration...")
logger.success("Application started successfully")

Font Showcase

def font_showcase():
    """Showcase all available fonts"""
    
    # Standard font - classic style
    logger.ascii_header("STANDARD", font="standard", border_style="blue")
    
    # Slant font - italic effect
    logger.ascii_header("SLANT", font="slant", border_style="green")
    
    # Doom font - bold effect
    logger.ascii_header("DOOM", font="doom", border_style="red")
    
    # Small font - compact style
    logger.ascii_header("SMALL", font="small", border_style="yellow")
    
    # Block font - blocky style
    logger.ascii_header("BLOCK", font="block", border_style="magenta")
    
    # Digital font - digital style
    logger.ascii_header("DIGITAL", font="digital", border_style="cyan")

⚠️ Usage Notes

ASCII Character Limitation

from pretty_loguru import is_ascii_only

def ascii_validation_demo():
    """Demonstrate ASCII character validation"""
    
    test_strings = [
        "HELLO WORLD",    # Correct
        "TEST 123",       # Correct  
        "HELLO 世界",      # Incorrect - contains Chinese characters
        "CAFÉ",           # Incorrect - contains accented characters
        "ASCII ONLY"      # Correct
    ]
    
    for text in test_strings:
        if is_ascii_only(text):
            logger.ascii_header(text, font="standard", border_style="green")
            logger.success(f"'{text}' can be used for ASCII art")
        else:
            logger.warning(f"'{text}' contains non-ASCII characters and cannot be used for ASCII art")
            logger.info(f"=== {text} ===")  # Use a normal header instead

Length Recommendation

def length_guidelines_demo():
    """Guidelines for text length"""
    
    # Recommended length - looks good
    short_titles = ["START", "OK", "ERROR", "DONE", "READY"]
