Truncated output in emacs

[acowley]

With GHC 7.8.3 and ghc-mod 4.1.5 from hackage and melpa-stable, I am getting truncated output in my GHC Info window in emacs. If I run ghc-modi manually, and check a file with a non-exhaustive pattern match, for example, I see the output I expect modulo formatting (and what I got in emacs with previous versions).

Warning: Pattern match(es) are non-exhaustiveIn an equation for ‘renameCommon’: Patterns not matched: _ (ConstDecl _ _ _) _ (MutDecl _ _ _) _ (ArrayDecl _ _ _) _ (MutAssign _ _)

In GHC Info, however, all I see is "Warning: Pattern match(es) are non-exhaustive".

I suspect it's a line break issue as I'm also having problems using M-t to insert type signatures. When I run that command expecting a longish type, I get a blank line inserted rather than a type signature.

I have the same problem (using the same settings for ghc and ghc-mod).
*GHC Info* only shows one line for me. I can see that all the info are received in *GHC Debug*.

For instance if *GHC Debug*displays:

info /home/vagrant/projects/haskell/7startups/Startups/Game.hs playerList
"playerList :: (GameStateOnly m) => m [PlayerId]"
"   -- Defined at /home/vagrant/projects/haskell/7startups/Startups/Game.hs:64:1"
OK

*GHC Info* only shows:

playerList :: (GameStateOnly m) => m [PlayerId]

#276 introduced this bug. 95c2b0c fixes this problem. I will release a new version soon.

4.1.6 solved the problem for me. Thank you; it wasn't fun losing ghc-mod for a while there! :)
