The error-location package

[Tags:bsd3, deprecated, library]
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]

And The Template Haskell version.

 $(dbg) [1,2,3]

 DEBUG main:Main main.hs:1:3 [1,2,3]

See module for a listing of all the functions with short descriptions, and the homepage for some more examples https:github.comgregwebsErrorLocation.hs
