Put the newline after errors instead of before them
This changes how error messages are represented slightly:
-
Foo.hs:3:7: error: [GHC-88464] Data constructor not in scope: ABC
|
3 | foo = ABC
| ^^^
Foo.hs:4:7: error: [GHC-88464] Variable not in scope: x
|
4 | bar = x
| ^
+
This mainly has an effect on ghci:
ghci> 5 * 'x'
-
<interactive>:1:1: error: [GHC-39999]
• No instance for ‘Num Char’ arising from the literal ‘5’
• In the first argument of ‘(*)’, namely ‘5’
In the expression: 5 * 'x'
In an equation for ‘it’: it = 5 * 'x'
+
ghci> foo
-
<interactive>:2:1: error: [GHC-88464] Variable not in scope: foo
+
ghci>
This makes it easier to see which expression an error belongs to and feels like more of a 'correct' behavior
