Comment(by duncan): Replying to [comment:8 simonmar]: > Looks ok to me, though the difference between ghc-pkg dump and ghc-pkg describe is slightly worrisome. That means `ghc-pkg describe | ghc-pkg update` is not the identity (I think we have a test that will break). It doesn't break yet because nothing uses ${pkgroot}. But yes, it'd have to be updated to use `--no-expand-pkgroot`. > What goes wrong if `ghc-pkg describe` uses `--no-expand-vars` by default? It's simply that it'll surprise people and perhaps existing tools. I'm happy to give it a go and see what breaks :-) -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/3268#comment:9> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
