[Hackage] #822: world-file does not support $arch, $os, $compiler

#822: world-file does not support $arch, $os, $compiler ---------------------------------+------------------------------------------ Reporter: josh | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.1.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ In my ~/.cabal/config, I have: install-dirs user prefix: /home/josh/.cabal/install/$arch-$os-$compiler This allows packages for multiple architectures (such as 32-bit and 64-bit) or multiple compilers (such as ghc6 and ghc7) to coexist. It also ensures that after upgrading the compiler, old libraries that won't work automatically disappear. Recent cabal added a "world" file, under ~/.cabal/world. I tried to move this to the same directory, by adding: world-file: /home/josh/.cabal/install/$arch-$os-$compiler/world However, this generated the following error: Error while Error while updating world-file. : /home/josh/.cabal/install/$arch-$os-$compiler/: openNewBinaryFile: does not exist (No such file or directory) From this, I'd guess that cabal doesn't support those variables in world- file like it does in prefix. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/822> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #889: Add option to list recursive dependencies of a package along with their licenses

#889: Add option to list recursive dependencies of a package along with their licenses ---------------------------------+------------------------------------------ Reporter: joeyadams | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ It should be possible to list all of the dependencies of a package, including their licenses. This would be useful for: * Developers writing proprietary applications. * Developers who don't want their liberally-licensed libraries to be "upgraded" to the GPL or similar by subtle dependencies. Attached is a simple patch that makes cabal-install list this information when the verbosity level is 2 or higher. Sample usage: {{{ $ cabal install --verbose=2 --dry-run gnutls Reading available packages... Resolving dependencies... base BSD3 bytestring BSD3 ffi BSD3 ghc-prim BSD3 gnutls GPL (Just (Version {versionBranch = [3], versionTags = []})) integer-gmp BSD3 monads-tf BSD3 rts BSD3 transformers BSD3 In order, the following would be installed: monads-tf-0.1.0.0 (new package) gnutls-0.1 (new package) }}} This is a quick hack, as I am not familiar with the Cabal codebase. This should probably be wrapped as a {{{--list-licenses}}} command line switch. Pretty-printing licenses would be a plus. I am already finding this feature useful, and hope others will too. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/889> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
