#12517: Simplify runghc command line options -------------------------------------+------------------------------------- Reporter: harendra | Owner: harendra Type: bug | Status: new Priority: normal | Milestone: Component: None | Version: 8.0.1 Resolution: | Keywords: runghc 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 harendra): A problem with transparently passing unrecognized flags to ghc is a very confusing and hard to understand behavior like this: {{{ runghc -package text-1.2.2.1 hello.hs text-1.2.2.0:1:74: Not in scope: ‘main’ Perhaps you meant ‘min’ (imported from Prelude) }}} What happened here is that runghc passed `-package` option to ghc but it did not pass text-1.2.2.0 which is being treated as the program name. This happens because of different ways to pass `-package` and its argument. So we will have to use `--ghc-arg=` for the arg like this: {{{ runghc -package --ghc-arg=text-1.2.2.1 hello.hs hello }}} If we had the same way to pass both the flag and the argument we won't have this very confusing behavior. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12517#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
