#12807: GHC is too verbose by default (source/object paths) -------------------------------------+------------------------------------- Reporter: hsyl20 | Owner: hsyl20 Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- With the default verbosity, GHC shows the path of the source file and the path of the object file (or "interpreted" in GHCi) making the lines very long as in the following example: {{{ [133 of 159] Compiling ViperVM.Arch.Linux.Internals.Input ( src/lib/ViperVM/Arch/Linux/Internals/Input.hs, .stack- work/dist/x86_64-linux/Cabal-1.24.0.0/build/ViperVM/Arch/Linux/Internals/Input.o ) [134 of 159] Compiling ViperVM.Arch.Linux.Input ( src/lib/ViperVM/Arch/Linux/Input.hs, .stack- work/dist/x86_64-linux/Cabal-1.24.0.0/build/ViperVM/Arch/Linux/Input.o ) [135 of 159] Compiling ViperVM.System.Input ( src/lib/ViperVM/System/Input.hs, .stack- work/dist/x86_64-linux/Cabal-1.24.0.0/build/ViperVM/System/Input.o ) [136 of 159] Compiling ViperVM.Arch.Linux.Internals.Sound ( src/lib/ViperVM/Arch/Linux/Internals/Sound.hs, .stack- work/dist/x86_64-linux/Cabal-1.24.0.0/build/ViperVM/Arch/Linux/Internals/Sound.o ) [137 of 159] Compiling ViperVM.Arch.Linux.Internals.Graphics ( src/lib/ViperVM/Arch/Linux/Internals/Graphics.hs, .stack- work/dist/x86_64-linux/Cabal-1.24.0.0/build/ViperVM/Arch/Linux/Internals/Graphics.o ) }}} In most cases, I think we don't need these paths. I propose that we keep this output for the verbose mode and that we change the default behaviour to something like: {{{ [135 of 159] Compiling ViperVM.System.Input (.hs -> .o) [136 of 159] Compiling ViperVM.Arch.Linux.Internals.Sound (.hs -> .o) -- GHCi [137 of 159] Compiling ViperVM.Arch.Linux.Internals.Graphics (.hs -> interpreted) }}} It is also particularily nice with BackPack that uses hashes in output paths: we may not want to expose them to users by default. Example: {{{#!patch [1 of 1] Including p[A=r:A] Instantiating p[A=r:A] - [1 of 2] Compiling A[sig] ( p/A.hsig, bkp26.out/p/p-8YQRY0unRYZCev5HBjXieS/A.o ) - [2 of 2] Compiling P ( p/P.hs, bkp26.out/p/p-8YQRY0unRYZCev5HBjXieS/P.o ) - [1 of 1] Compiling M ( q/M.hs, bkp26.out/q/M.o ) + [1 of 2] Compiling A[sig] (.hsig -> .o) + [2 of 2] Compiling P (.hs -> .o) + [1 of 1] Compiling M (.hs -> .o) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12807 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

It can be used instead of `-v2` (or higher verbosity) which may be too verbose. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12807#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
