Readme

This package provides a generic Core-to-Core pass for annotating Haskell expressions with the original source locations, making them available at runtime.

You can use it to build a GHC Plugin tailored to your own library by providing a predicate to select interesting expressions for annotation and a function to annotate the expressions.
