To add support for GHC 7.8 in a way that the user doesn't have to care about the version, there has to be a way to make Typeable instances via TH in GHC 7.8. This is currently impossible, but with StandaloneDeriving support for TH, it would be possible. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8100> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#9005: Ship default bash completion file with ghc ------------------------------------+------------------------------------- Reporter: td123 | Owner: Type: feature request | Status: new Priority: lowest | Milestone: Component: None | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Now that ticket #7843 has been closed, it would be great to ship a default implementation of a bash completion file for ghc. Since there isn't a standard location to install completion files across distros, it might be good to have an optional flag during configure to specify a location and if one is specified, install the bash completion file into that location. The following links provide implementations that have worked for me: http://www.reddit.com/r/haskell/comments/236qkb/autocomplete_command_line_o… https://ghc.haskell.org/trac/ghc/wiki/AutocompleteGHCFlags -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9005> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I've checked the file `compiler/prelude/primops.txt.pp` which is processed to generate the file I'm having problems with and that file is fine. I've cloned a new copy of the repo and done the usual `perl boot && ./configure && make` only to see exactly the same result. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9828> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
