DBCDiff is a Python-based command-line tool for comparing individual DBC files or entire folders containing DBC files. It generates comparison reports in various formats such as JSON, HTML, or Whatever. The reporting system is extensible, allowing you to add custom templates for new report types.
- Compare single DBC files or directories containing multiple DBC files.
- Identify changes, additions, and deletions between two sets of DBC files.
- Optionally include unchanged DBC files in the report.
- Generate reports in multiple formats (json, html, etc.).
- Extendable report templates for custom output formats.
