#9970: Export more types in GHC.RTS.Flags -------------------------------------+------------------------------------- Reporter: | Owner: RyanGlScott | Status: new Type: feature | Milestone: request | Version: 7.10.1-rc1 Priority: normal | Operating System: Unknown/Multiple Component: | Type of failure: Other libraries/base | Blocked By: Keywords: | Related Tickets: Architecture: | Unknown/Multiple | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- There are some ADTs in {{{GHC.RTS.Flags}}} that have arguments whose types are not exported. These types are: * {{{GiveGCStats}}} (found in {{{GCFlags}}}) * {{{DoCostCentres}}} (found in {{{CCFlags}}}) * {{{DoHeapProfile}}} (found in {{{ProfFlags}}}) * {{{DoTrace}}} (found in {{{TraceFlags}}}) This makes it pretty difficult to do anything useful with them, since they can't be pattern-matched. In addition, there are some unexported type synonyms: * {{{type Time = Word64}}} * {{{type Nat = #{type unsigned int} }}} (likely a {{{Word32}}}) The Haddock docs for {{{GHC.RTS.Flags}}} don't give much of an indication of what {{{Time}}} and {{{Nat}}} are, and since they're already documented in [https://phabricator.haskell.org/diffusion/GHC/browse/master/libraries/base/G... the source], they should probably be exported. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9970 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
