#2521 closed bug (fixed)

Trailing colon on GHC_PACKAGE_PATH doesn't work with ghc-pkg.

According to section of the Users' Guide, appending a colon to GHC_PACKAGE_PATH should include the system libraries, and this can be verified with ghc-pkg. While the colon does appear to work for ghci (as verified with -v), it does not appear to work for ghc-pkg.

$ echo '[]' > temp.conf
$ export GHC_PACKAGE_PATH=`pwd`/temp.conf:
ghc-pkg list

  * FIX #2521: trailing colon in GHC_PACKAGE_PATH
  This was broken in the System.FilePath switchover, since filepath's
  splitSearchPath doesn't do what we want (it ignores empty
  components on Windows, and treats them as "." on Unix).  So we use our
  own hand-rolled version, just like GHC.
