Colorized error messages result in hard-to-read .dump-* files
To see this, compile this file:
module Main where
x :: String -> String
x s = print (reverse s + 1)
with ghc-stage2 -ddump-tc-trace -ddump-to-file
. If you look at the resulting .dump-tc-trace
file with a text editor like vim
, you'll see at the bottom:
...
Tc7a
checkMain fail Main main
Adding error:
^[[;1mBug.hs:1:1: ^[[;1m^[[31merror:^[[;1m
The IO action ‘main’ is not defined in module ‘Main’^[[0m
The error message is now much harder to discern that before the introduction of colorized error messages.
