#13697: Teach GHCi to deduplicate history -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 8.0.1 Resolution: | 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: | -------------------------------------+------------------------------------- Comment (by bgamari): Here's a quick reproducer, 1. Start `ghci`. 2. Enter a command: `putStrLn "hello" <enter>` 3. Enter another command; `putStrLn "hi again" <enter>` 4. Press `<up arrow>` once to select the `hi again` command, press `<enter>` 5. You will now need `<up arrow>` three times to get back to the `hello` command as the `hi again` command appears twice in history. This is in contrast to, e.g. `bash`, where it will only appear once. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13697#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
