#12851: Regression: GHC doesn't show filepaths by default anymore -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: bug | Status: new Priority: low | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: regression Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by hsyl20): Author of the aformentioned patch here. Sorry for the lack of advertising of this change. 1. I didn't want the patch to be too radical, that is why I left the extensions "(.hs -> .o)": the paths could be inferred from the module name (at least in simple cases) but the extensions may not (.lhs for instance). I kept the previous object path display: "nothing"/"interpreted" when the target is HscNothing/HscInterpreted. Nevertheless I agree that we could totally avoid it. It is already what haskell-mode is doing (thanks @gracjan for the comment on Phab:D2679#79222). So this doesn't seem to be controversial and I will make a patch for this. 2. Do we need a new flag? Initially SPJ asked for one in #12807 to restore the old behaviour and it avoids enabling a too verbose mode. Also we would like verbosity levels to be aliases for sets of verbosity flags (see #12822). 3. Flag name: there has been a little bikeshedding about the flag name already (see Phab:D2679#77954). Initially I chose "-fshow-module-paths" but @nomeata thought "-fshow-source-paths" would be better and I don't have a strong opinion on it. I agree that having two flags (for source/object paths) would be more correct. 4. Hiding the object path by default: it doesn't seem controversial. Let's do that. 5. Hiding the the source path by default: I think we should as it is more newcomer friendly and in most cases I think we don't care about it (but I agree that it depends on your workflow). haskell-mode already hides it. Maybe we should have a poll on haskell-cafe or something. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12851#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
