[GHC] #7863: Verbosity level for quieter Template Haskell
#7863: Verbosity level for quieter Template Haskell -----------------------------+---------------------------------------------- Reporter: dolio | Owner: Type: feature request | Status: new Priority: normal | Component: Template Haskell Version: 7.6.3 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- In projects with large numbers of dependencies, use of template haskell can cause very large amounts of output that aren't particularly interesting. However, it seems that the only verbosity level that quiets template haskell output is -v0, which also turns off normal indications of build progress. It would be pleasant to have a way to turn off template haskell loading messages while retaining the rest of -v1 output. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7863 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Maybe they can be be made to come out only with -v2? Simon -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7863#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Stuff like the following: {{{ Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done.

There are actually 103 lines total, and they get printed multiple times, because we use template Haskell in multiple files. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7863#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
