📦 Installation

pip install file_diff_analyzer

from file_diff_analyzer import FileChangeAnalyzer

Compare two files:

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

Compare two directories:

• results = analyzer.analyze_directories(
• r"C:\Projects\version1",
• r"C:\Projects\version2"
• )
• print("Directory analysis complete. Output folder:", results)
