Improve locations in ghci errors
This shows GHC complaining of an error in line 9 of a 7 line file. The error is really on line 4. My guess is it's adding the line within the :{
... :}
to the line of the :}
, in which case the best fix is probably to remember the position of the :{
and set the line number to that when evaluating the expression.
Prelude> :! cat script_me
:{
let y1 = 1
y2 = 2
Y3 = 3
y4 = 4
y5 = 5
:}
Prelude> :! wc -l script_me
7 script_me
Prelude> :script script_me
script_me:9:5: Not in scope: data constructor `Y3'
Additionally, errors in .ghci
files currently have <interactive>
as their location. Probably sourceConfigFile
in ghc/InteractiveUI.hs
should set the filename.
