#10663: ghci ignores stuff after an import command and a semicolon -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.10.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: GHC accepts | Unknown/Multiple invalid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by osa1): * cc: osa1 (added) Comment: I'm trying to understand expected syntax here. It seems like I can only put expressions after the first semicolon, other GHCi commands don't work: {{{ λ:6> import Data.List; x; x + y λ:7> import Data.List; import Data.Char <no location info>: parse error in import declaration λ:8> let x = 10 λ:9> x; x; x <interactive>:9:2: parse error on input ‘;’ λ:10> let y = 10; y <interactive>:10:14: parse error (possibly incorrect indentation or mismatched brackets) λ:11> import Data.Char; x λ:12> }}} Also, I can't see anything related with semicolons in user manual "Using GHCi" section(https://downloads.haskell.org/~ghc/latest/docs/html/users_guide /interactive-evaluation.html) so it seems to me like this semicolon behavior is not intended and just a side effect of the used parser. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10663#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
