#8051: GHCi: confusing `:set +m`/`:{` interaction & wrong line-numbers in multi- line input ------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- As mentioned in ticket:8047#comment:1 GHCi exhibits a line-numbering offset bug when multi-line input is evaluated. Morever, when `:set +m` is active, `:{`-entered multi-input may trigger multi-line input continuation, e.g.: {{{ Prelude> :set +m Prelude> :{ Prelude| let x = () Prelude| y = () Prelude| :} Prelude| z = () Prelude| Prelude> }}} The attached patch fixes both issues, but does so in an admittedly hacky way... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8051 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
