eslint formatter unix

This tool converts ESLint results into a UNIX-friendly plain-text format that is easy to parse in shells and CI logs. It accepts ESLint JSON or text, normalizes file paths, and emits a single-line entry per lint message with a predictable layout. Conceptually, it acts as a formatter that decouples lint analysis from presentation, enabling fast, repeatable reviews across projects. It is particularly valuable for developers who pipe lint results through scripts, log aggregators, or pre-commit checks where readability and consistency matter.
Core value comes from a reduced cognitive load; users can quickly scan paths, locations, and messages without verbose rule formats. The tool supports default UNIX-style output and optional JSON-friendly output for automated consumers. Advanced options include colorization, severity filtering, and streaming processing to handle large reports efficiently. Use cases range from local development to CI pipelines where lint results must be compact and parseable by downstream tools.
Key features include standardized line formatting, stable separators, and predictable handling of missing fields, making it suitable for cross-project dashboards and anomaly detection. It complements ESLint by providing a uniform presentation layer that accelerates triage and helps teams maintain code quality across repositories.
