#13175: Documenting what can be derived 'out of the box' by GHC's "deriving" -------------------------------------+------------------------------------- Reporter: carette | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Documentation | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Documentation | Unknown/Multiple bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by carette): Unfortunately I 'looked' via Google. I expected to find it that way... Once the information is somewhere, I will then expect that that will indeed work. But, in the meantime, I am still at a loss as to where to put it. One of the problems is that when you search for "GHC" and "deriving", the principal hits are to section 7.5 of the manual (https://downloads.haskell.org/~ghc/7.8.4/docs/html/users_guide/deriving.html) which documents the extensions to this mechanism. If you dig really (really!) hard, you eventually find section 4.3.3 of the Haskell 98 report (https://www.haskell.org/onlinereport/decls.html#derived-decls) which documents "deriving" (the 2010 report's 4.3.3 is essentially identical). But Google doesn't seem to like that much, so it doesn't show up. But the list in those reports is not the same as the list above! So I am still at a loss as to where to put this. GHC's own documentation does not define "deriving" (because the Haskell reports already do), which would have been my first thought. So maybe in 7.5 somewhere? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13175#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
