DiffX – Next-Generation Extensible Diff Format

a year ago

DiffX is a proposed next-generation extensible diff format that builds upon Unified Diffs.
Unified Diffs lack standardization in encodings, revisions, metadata, and file path representations.
DiffX aims to standardize diff parsing, metadata storage, and extensibility while remaining backward-compatible.
Key features of DiffX include standardized parsing rules, formalized metadata storage, and support for multiple commits in a single diff file.
DiffX supports Git-compatible binary diffs and text encodings, ensuring compatibility with existing tools.
The format is designed to be mutable, allowing tools to modify diffs without breaking them.
DiffX does not aim to replace existing formats or create vendor lock-in but to enhance them.
Implementations like pydiffx for Python are available, with Review Board being an early adopter.
