#10576: REPL returns list of all imported names when operator completion requested -------------------------------------+------------------------------------- Reporter: Geraldus | Owner: thomie Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | completions complete command Type of failure: Incorrect result | operator at runtime | Architecture: Blocked By: | Unknown/Multiple Related Tickets: #9996 | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by thomie): * owner: => thomie * related: => #9996 Comment: Also reported as #9996. The problem comes from using the default `word_break_chars` when completing identifiers in `ghc/ghc/InteractiveUI.hs`: {{{ -- We initialize readline (in the interactiveUI function) to use -- word_break_chars as the default set of completion word break characters. -- This can be overridden for a particular command (for example, filename -- expansion shouldn't consider '/' to be a word break) by setting the third -- entry in the Command tuple above. -- -- NOTE: in order for us to override the default correctly, any custom entry -- must be a SUBSET of word_break_chars. word_break_chars :: String word_break_chars = let symbols = "!#$%&*+/<=>?@\\^|-~" specials = "(),;[]`{}" spaces = " \t\n" in spaces ++ specials ++ symbols wrapIdentCompleter = wrapCompleter word_break_chars }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10576#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
