#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 nomeata): What I observe in bash (and miss in ghci as well) is that {{{ $ ls $ ls $ history |tail -n 3 4992 man bash 4993 ls 4994 history |tail -n 3 }}} i.e. there are no *successive* duplicated entries. But {{{ $ ls $ echo hi $ ls $ history |tail -n 4 4995 ls 4996 echo hi 4997 ls 4998 history |tail -n 4 }}} so there is no duplication of everything. I believe the OP asks for the former (and I support this.) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13697#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
