[GHC] #9698: GHC_PACKAGE_PATH should be more lenient for empty paths
#9698: GHC_PACKAGE_PATH should be more lenient for empty paths -------------------------------------+------------------------------------- Reporter: Fuuzetsu | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Consider a working {{{GHC_PACKAGE_PATH=foo:bar:baz:}}}. It is not uncommon that we would want to append som extra vars later which might possibly be empty, perhaps resulting in {{{GHC_PACKAGE_PATH=foo:bar:baz::qux:}}}. Unfortunately, due to the {{{::}}} GHC tries to looking for a package at the empty path and shows the usual error about not being able to find the package. This forces the user to set up various safeguards (such as {{{${GHC_PACKAGE_PATH:+:} }}} bashism) at the inital binding location. It'd be great if GHC would simply skip over empty paths. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9698 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
