The error-location package
Deprecated in favor of file-location
Error functions that give file location information
> $(err "OH NO!") > > main:Main main.hs:16:1 OH NO!
Notice how it displays package:module file:line:character It exposes the functions err (error), undef (undefined), and trc (Debug.Trace.trace). All of these behave the same as their normal counterpart but also spit out a location.
I also included my favorite helper, debug, which is like trace but just show the value.
> debug [1,2,3] > > DEBUG: [1,2,3] > [1,2,3]
And The Template Haskell version. > debug [1,2,3] > > DEBUG main:Main main.hs:1:3 [1,2,3] > [1,2,3]
See module for a listing of all the functions with short descriptions, and the homepage for some more examples <https://github.com/gregwebs/ErrorLocation.hs>
