library0.1.0jsnpmunverified

An ESLint custom formatter that summarizes lint errors into bar charts grouped by rule and file. Version 0.1.0 is the latest stable release. It is a lightweight, zero-dependency tool that provides an at-a-glance visual summary, ideal for CI output or team dashboards. Unlike other formatters (e.g., stylish, tap), it uses unicode bar charts to show proportional error distribution. The package is rarely updated and considered stable.

gotchaOnly works with ESLint < 9.x. ESLint 9 changed formatter API and removed --format support for custom paths.
gotchaOutput uses unicode block characters; some terminals may not render bar charts correctly.
