#9259: GHCi should list its available command line options -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: Component: Driver | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by kolmodin): Making `--interactive` and `--show-options` work together is simple, just a few more lines to `setMode`. The time consuming part with this task is to cleanly separate which flags work in GHC and which work in GHCi. The flags are defined in a few different places; * `ModeFlags` defined in `ghc/Main.hs` which apply to both GHC and GHCi. * `StaticFlags` defined in `compiler/main/StaticFlags.hs` which applies to both GHC and GHCi. * DynFlags defined in `compiler/main/DynFlags.hs`. There are a few different kinds of flags here (dynflags, package flags, fflags, fwarn, ...), each of which where some are for GHC and some for GHCi. For some flags there is code guarding to make sure you don't mix them, like together with `--interactive` you cannot use `-prof`, `-threaded`, `-unreg`, `-debug` or `-ticky`. For other flags there is no such code, and it's not always obvious where each flag has effect. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9259#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
