#13037: Single-Stepping evaluation in GHCi -------------------------------------+------------------------------------- Reporter: vanto | Owner: Type: feature request | Status: closed Priority: normal | Milestone: Component: GHCi | Version: 8.0.1 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by nomeata): * status: new => closed * resolution: => invalid Comment: As great as it would be to have this, I believe it is unrealistic within the scope of GHC. The code that is run by GHC has little resemblance with the original source code, and `[1..3]` does not step to `[2,3]`, for example. The closest support for this is the GHCi debugger, see the user’s guide for it. But it is more suited for experienced developers. There might be dedicated tools for teaching out there that do that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13037#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
