Quick Start

Using Python API

from scratch3_analyzer import Scratch3Analyzer

# Create analyzer instance
analyzer = Scratch3Analyzer()

# Analyze a single .sb3 file
result = analyzer.analyze_file(
    sb3_path="my_project.sb3",
    output_excel="analysis_results.xlsx"  # Optional: export to Excel
)

# Print some statistics
print(f"Total blocks: {result['complexity']['total_blocks']}")
print(f"Total sprites: {result['complexity']['total_sprites']}")
print(f"Complexity score: {result['complexity']['complexity_score']}")

Using Command Line

# Analyze a single file
scratch3-analyzer analyze my_project.sb3 --output results.xlsx

# Analyze all files in a directory
scratch3-analyzer batch ./projects --output summary.xlsx

# Show version
scratch3-analyzer --version

# Show help
scratch3-analyzer --help

Graphical User Interface (GUI)

Starting from version 1.1.0, Scratch3 Analyzer includes a graphical user interface.

Launch GUI:

scratch3-analyzer --gui

GUI Features:

* Single file analysis: Select and analyze individual .sb3 files
* Batch processing: Analyze all .sb3 files in a directory
* Recursive search: Option to search subdirectories for .sb3 files
* Excel export: Export results to Excel with customizable output path
* Progress tracking: Real-time progress display during analysis
* Results display: View analysis results directly in the application
