How To Install ghc-safe on Fedora 36
Introduction
In this tutorial we learn how to install ghc-safe on Fedora 36.
What is ghc-safe
A library wrapping ‘Prelude’/‘Data.List’ functions that can throw exceptions, such as ‘head’ and ‘!!’. Each unsafe function has up to four variants, e.g. with ’tail’ * ’tail * ’tailMay * ’tailDef * ’tailNote supplements the error message. * ’tailSafe the case of ’tail’. This package is divided into three modules * “Safe” contains safe variants of ‘Prelude’ and ‘Data.List’ functions. * “Safe.Foldable” contains safe variants of ‘Foldable’ functions. * “Safe.Exact” creates crashing versions of functions like ‘zip’ (errors if the lists are not equal) and ’take’ (errors if there are not enough elements), then wraps them to provide safe variants.
