#1612: GHC_PACKAGE_PATH and $topdir bug -------------------------------------+------------------------------------- Reporter: eivuokko | Owner: Type: bug | Status: new Priority: lowest | Milestone: ⊥ Component: Package system | Version: 6.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by thomie): * os: Windows => Unknown/Multiple * milestone: 7.12.1 => ⊥ Comment: The bug is minor, but it's still there after 8 years. Here goes: In the file `/opt/ghc/7.10.1/lib/ghc-7.10.1/package.conf.d/base-4.8.0.0-1b689eb8d72c4d4cc88f445839c1f01a.conf` I make the following change: {{{ -haddock-interfaces: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/base-4.8.0.0/base.haddock +haddock-interfaces: $topdir/../../share/doc/ghc/html/libraries/base-4.8.0.0/base.haddock }}} The path that ghc-pkg returns for the haddock-interfaces files exists: {{{ $ ghc-pkg field base haddock-interfaces --package- db=/opt/ghc/7.10.1/lib/ghc-7.10.1/package.conf.d/ haddock-interfaces: /opt/ghc/7.10.1/lib/ghc-7.10.1/../../share/doc/ghc/html/libraries/base-4.8.0.0/base.haddock }}} But when I do the same query while telling ghc-pkg that the global package database is an empty package.conf.d directory, it returns the following: {{{ $ mkdir package.conf.d $ ghc-pkg field base haddock-interfaces --package- db=/opt/ghc/7.10.1/lib/ghc-7.10.1/package.conf.d/ --global-package- db=./package.conf.d/ haddock-interfaces: /home/thomas/package.conf.d/../../share/doc/ghc/html/libraries/base-4.8.0.0/base.haddock }}} Note that that last path doesn't exist. It made the wrong substitution for $topdir. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/1612#comment:17> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #10505: more specific types in the generated *_stub.h files

#10505: more specific types in the generated *_stub.h files -------------------------------------+------------------------------------- Reporter: imz | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.6.1 Component: Compiler | Operating System: Linux (FFI) | Type of failure: Other Keywords: | Blocked By: Architecture: | Related Tickets: #2979, #8222 Unknown/Multiple | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Having a declaration like: {{{#!hs foreign export ccall "respond" respond :: CWString -> IO CWString }}} all the types in the corresponding `_stub.h` are `HsPtr`. Wouldn't it be possible to write more specific types reflecting my expectations, i.e., `wchar_t *`? It would be nice in order to signal automatically to the C code which uses the Haskell functions that the types of the Haskell functions changed. In simple cases, one could simply include the stub.h, and get automatically an error if the C code doesn't match the new types. I've tried using a CTYPE pragma (cf. #2979 , #8222 ) on a newtype to get such results: {{{#!hs newtype {-# CTYPE "wchar_t *" #-} CWString' = CWString' CWString foreign export ccall "respond" respond :: CWString' -> IO CWString }}} but that still produces `HsPtr`. (Well, I see, the CTYPE pragma was mostly intended for imports rather than exports.) -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10505> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#7495: generalizing overloaded list syntax to Sized Lists, HLists, HRecords, etc -------------------------------------+------------------------------------- Reporter: nwf | Owner: carter Type: feature request | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: #9883 | Blocking: 9883 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by s9gf4ult): Your example is much more complex, why so many parameters in `HetCons` and functional dependencies? Pattern matching overload is interesting idea. Pattern `(x:xs)` should be considered by compiler as `HCons x xs` for `HList`, but compiler knowns about `HList` just after type inference and see pattern `(x:xs)` after parsing and desugaring, so pattern `(x:xs)` must be replaced with `HCons x xs` after type inference somehow. I am not very familiar with GHC internals anyway. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7495#comment:13> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
