semdiff is a semantic diff tool written in Rust for comparing files and directories.
It walks two directory trees, detects file types, and produces human-friendly reports for differences in text, JSON, binary files, images, and audio. The software can emit report output as a console summary, JSON, or HTML, making it suitable for both quick inspection and more detailed review.
This is free and open source software.
Key Features
- Compares two inputs as expected versus actual files or directories.
- Supports semantic diffing for text, JSON, binary, image, and audio data.
- Generates summary, JSON, and HTML reports.
- Can ignore JSON object key order during comparisons.
- Provides configurable tolerances for image and audio comparisons.
- Cross-platform support – runs under Linux, macOS, and Windows.
