#5687: Friendly Interface for auto-completion of GHCi ---------------------------------+------------------------------------------ Reporter: linsumang | Owner: Type: feature request | Status: patch Priority: normal | Milestone: 7.6.2 Component: GHCi | Version: 7.2.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by hvr): I've attached a patch providing a more refined `:complete` command: This one takes an optional range (1-based indexing, syntax `[n-][m]` where `n` denotes first index, and `m` the last index shown), allowing to slice the result list; moreover the first line emitted now contains: {{{ <completions-printed-count> <total-completions-count> <line-prefix> }}} And here's an example session again: {{{ Prelude> :complete Syntax: :complete repl [<range>] <quoted-string-to-complete> Prelude> :complete repl 5 "import For" 5 21 "import " "Foreign" "Foreign.C" "Foreign.C.Error" "Foreign.C.String" "Foreign.C.Types" Prelude> :complete repl 5-10 "import For" 6 21 "import " "Foreign.C.Types" "Foreign.Concurrent" "Foreign.ForeignPtr" "Foreign.ForeignPtr.Safe" "Foreign.ForeignPtr.Unsafe" "Foreign.Marshal" Prelude> :complete repl 20- "import For" 2 21 "import " "Foreign.StablePtr" "Foreign.Storable" Prelude> :complete repl "map" 3 3 "" "map" "mapM" "mapM_" }}} -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/5687#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
