#8113: Cannot override ghci builtin commands with :def[!] -------------------------------------+------------------------------------ Reporter: duncan | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by hvr): Fyi, while looking into implementing a `:builtin <cmd> [args]`-like facility I noticed it's already there, by using `::<cmd>`: {{{ :def <cmd> <expr> define command :<cmd> (later defined command has precedence, ::<cmd> is always a builtin command) }}} So this leaves the issue of `:def!` not doing what it's expected to do (and probably to add documentation about the `::<cmd>` feature to the GHC user guide, as I didn't see it mentioned there). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8113#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
