[GHC] #10785: ghc-pkg appends colon to db path when piped/redirected
#10785: ghc-pkg appends colon to db path when piped/redirected -------------------------------------+------------------------------------- Reporter: jgertm | Owner: jgertm Type: bug | Status: new Priority: normal | Milestone: Component: ghc-pkg | Version: 7.10.2 Keywords: colon pipe | Operating System: Unknown/Multiple redirect ghc-pkg list | Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Quite simple. Compare the first line of output from {{{#!sh ghc-pkg list ghc-pkg list | head }}} In the second command's output, a colon gets appended at the end of the first line, compared to the first command. This is generally undesired behaviour, since the intent of redirection is to further process the output of the original command. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10785 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The function to change is `listPackages` in `utils/ghc-pkg/Main.hs`. Also test what happens on a broken package, and notice hidden packages are currently printed differently as well: {{{ $ ghc-pkg list | grep ghc-7.10.2 /opt/ghc/7.10.2/lib/ghc-7.10.2/package.conf.d: (ghc-7.10.2) }}} As a workaround, use: `ghc-pkg list --simple-output`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10785#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
