EIPW is an advanced EIP validator, surpassing its predecessor EIPV, designed to efficiently check the compliance of Ethereum Improvement Proposals. It supports file and directory inputs and offers configurable output formats (text, JSON), enabling seamless integration into existing workflows. EIPW enhances proposal validation through customizable linting rules and provides an extensive array of pre-defined lints to ensure proposals adhere to Ethereum’s rigorous standards. The validator is packaged for JavaScript and WebAssembly environments, accessible via npm, making it suitable for dynamic type-checking in modern web applications. This tool is essential for developers and project maintainers aiming to maintain high documentation standards within the Ethereum ecosystem.
