Hello,

I'd like to change how the error messages from GHC get wrapped.

I am using the following code:

  flip gcatch handler $ do

    runStmt "let f (x, y, z, w, e, r, d , ax, b ,c,ex ,g ,h) = (x :: Int) + y + z" RunToCompletion

    runStmt "f (1, 2, 3)" RunToCompletion

    return ()

  where

    handler :: SomeException -> Ghc ()

    handler e = 

      liftIO $ putStrLn $ "Exception:\n" ++ show e

      

The output I am getting looks like this:

I would like the types to not wrap at all, or wrap at some very long length along the lines of 200-300 characters.

I have seen the `pprUserLength` and `pprCols` fields in DynFlags, but they don't seem to do anything.

What should I do?

Thanks!

Andrew
