#8193: document :kind! in ghci built-in help ------------------------------------+-------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.4.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: Documentation bug Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+-------------------------------------- Patch attached. I have the wording as: {{{ :kind[!] <type> show the kind of <type> (!: also show the normalised type) }}} could use some tweaking perhaps. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8193> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

We can work around the issue, but GHC is to blame here. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4983#comment:5> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I got {{{ cabal: thread blocked indefinitely in an MVar operation }}} probably in the preprocessing step, but apart from that, it seems to work (see attached output file). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/3103#comment:17> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Moreover, if we were to display the output of the renamer then this program {{{ f x = g [qq| ...blah... |] x }}} would display, after renaming, as {{{ f x = g (...expanded quote...) x }}} where the parens are actively helpful in parsing! Let's do that. Thanks. Simon -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7918#comment:14> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
