Errata

MIT License Hackage CI

Errata is an extremely customizable error pretty printer that can handle many kinds of error formatting.

Features

Errata can handle errors that are all over the source or errors that are connected to each other spanning multiple lines. You can be as simple or as fancy as you like!

You can also customize the format of the printer in several ways:

Examples

A clean, modern error message that is trying to be helpful:

An error message that points out that the fold function was not found in scope. It then asks if the user meant to use foldl or foldr

A busy error message with underlining and connections:

An error message that highlights mismatching types in an if expression. The first section underlines the mismatching values, and the second section underlines the if expression
