Error message catalog

Errors are submitted and maintained by the Clojure community through GitHub issues and pull requests, ensuring a diverse and real-world range of error scenarios.

Each error is documented in a markdown file with sections for exception, description, causes, and solutions, providing clear and consistent information for quick understanding.

The consistent format enables potential tooling integration, such as IDE suggestions or contextual search, as highlighted in the README for future enhancements.

Errors are organized into Clojure core, ClojureScript core, and library-specific errors, making it easy to navigate and find relevant documentation quickly.
