#11606: name shadowing warnings don't trigger on standalone declarations in ghci -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: (none) Type: bug | Status: closed Priority: high | Milestone: 8.8.1 Component: GHCi | Version: 7.10.3 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | ghci/scripts/T11606 Blocked By: | Blocking: Related Tickets: #16096 | Differential Rev(s): MR:97 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ömer Sinan Ağacan ): In [changeset:"a34ee61545930d569d0dbafb3a4a5db3a7a711e5/ghc" a34ee615/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="a34ee61545930d569d0dbafb3a4a5db3a7a711e5" Refactor GHCi UI to fix #11606, #12091, #15721, #16096 Instead of parsing and executing a statement or declaration directly we now parse them first and then execute in a separate step. This gives us the flexibility to inspect the parsed declaration before execution. Using this we now inspect parsed declarations, and if it's a single declaration of form `x = y` we execute it as `let x = y` instead, fixing a ton of problems caused by poor declaration support in GHCi. To avoid any users of the modules I left `execStmt` and `runDecls` unchanged and added `execStmt'` and `runDecls'` which work on parsed statements/declarations. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11606#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
