📦 Installation

pip install file_diff_analyzer

from file_diff_analyzer import FileChangeAnalyzer

output_dir = "my_analysis_output"

analyzer = FileChangeAnalyzer(output_dir)

Compare two files:

• result = analyzer.analyze_files(
• r"D:\Projects\old_version\main.c",
• r"D:\Projects\new_version\main.c"
• )
• print("Saved analysis to:", result)
