A catalog of broken Elm programs / data to improve error messages
The error-message-catalog is a collection of Elm programs designed to systematically trigger every possible error message in the Elm language. The project aims to build a comprehensive dataset of error messages that can be analyzed to identify patterns, discover quick fixes, and improve message quality—particularly for common issues that beginners encounter. By gathering this complete set of error examples, the catalog provides empirical data to guide improvements to Elm's error messaging system overall.
