#4243: Make a proper options parser for the RTS -------------------------------------+------------------------------------- Reporter: igloo | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 6.13 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: 7535 Related Tickets: #9839 #13308 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by AndreasK): * related: #9839 => #9839 #13308 Comment: When parsing arguments to flags ghc treats leading whitespace different depending on the flag. ghc +RTS '-N 2' -s -RTS --version Here '-N 2' is parsed as -N2 ghc +RTS '-s file' -RTS --version Here '-N 2' is parsed as '\ file', a filename starting with a space. If this rework ever happens leading spaces in arguments should either be uniformly ignored or treated as errors. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4243#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
