About:
Protolint is a command-line tool designed to enforce consistent style and conventions across Protocol Buffer definitions. It supports both linting to detect violations and automatic fixing of many common issues. The tool is highly configurable, allowing teams to define custom rules and maintain clean, readable .proto files.

Key Features:

Supports both linting and automatic fixing of style violations
Highly configurable via a .protolint.yaml file
Extensible with custom plugins for unique rules
Enforces consistency across large codebases

Use Cases:

Enforcing a consistent style guide for Protocol Buffers in a team setting
Integrating into CI/CD pipelines to automatically check .proto files
Automatically formatting legacy .proto files to meet new standards

Alternatives:

buf – Buf is a broader tool for managing Protocol Buffers that includes linting, but protolint is more focused on style and formatting.
