Yes, if you need to parse diff files programmatically. The package is simple, dependency-free, and permissively licensed. However, maintenance is dormant—no updates since 2024-09-09—so evaluate whether the feature set meets your needs and whether you can maintain a fork if required. Verify that the available properties are sufficient for your use case.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6 or later.
- Low install friction with no runtime dependencies.
- Maintenance is dormant—last commit was 2024-12-30, but the repository remains active and the package has received no updates since its 2024-09-09 release.

What it is and what it does
diff-parser is a lightweight Python library for reading and extracting structured information from diff files. It takes a path to a git diff or .diff file and parses it into blocks, each representing a changed file with accessible properties like old and new filenames, filepaths, source and target hashes, and change type.
The package has no external runtime dependencies and supports Python 3.6 and later. It is intended for developers who need programmatic access to diff metadata—for example, in build tools, code review automation, or version control workflows. The project is dormant but stable; the last commit was 2024-12-30, and no security vulnerabilities have been reported.
Use it for
- Extract metadata about changed files from git diff output in CI/CD pipelines for conditional build steps.
- Analyze which files were modified in a commit to generate automated reports or trigger downstream tasks.
- Parse .diff files from patch management or code review tools to identify affected modules or dependencies.
- Build tooling that needs to programmatically inspect file changes without shelling out to git commands.
