  11
  12 * MAYBE Add a substituter that uses the GNUnet DHT or [[http://libswift.org][libswift]]
  13
  14 Would be neat if binaries could be pushed to and pulled from the GNUnet DHT or
  15 rather libswift (since DHTs aren’t suited for large payloads).  Guix users
  16 would sign their binaries, and define which binaries they trust.
  17
  18 Use UPnP and similar to traverse NAT, like ‘filegive’ does.
  19
  20 * user interface
  21 ** add guile-ncurses interface
  22
  23 * extend <package>
  24 ** add ‘recommends’ field
  25
  26 For instance, glibc, binutils, gcc, and ld-wrapper would recommend each other.
  27 ‘guix package -i’ could ask interactively (?), or allow users to follow all or
  28 none of the recommendations.
  29
  30 ** add a ‘user-environment-hook’
  31
  32 This should specify builder code to be run when building a user
  33 environment with ‘guix-package’.  For instance, Texinfo’s hook would
  34 create a new ‘dir’.
  35
  36 ** extend ‘propagated-build-inputs’ with support for multiple outputs
  37
  38 #+BEGIN_SRC scheme
  39   (outputs '("out" "include"))
  40   (propagated-build-inputs
  41     `(((("i1" ,p1 "o1")
  42         ("i2" ,p2))
  43        => "include")
  44       ("i3" ,p3)))
  45 #+END_SRC
  46
  47 * synchronize non-GNU package descriptions with the [[http://directory.fsf.org][FSD]]
  48
  49 Meta-data for GNU packages, including descriptions and synopses, can be
  50 dumped from the FSD:
  51 http://directory.fsf.org/wiki?title=GNU/Export&action=purge .
  52 We could periodically synchronize with that.
  53
  54 * add a guildhall build system
  55
  56 The Guildhall is Guile’s packaging system.  It should be easy to add a
  57 ‘guildhall-build-system’ that does the right thing based on guildhall
  58 recipes.
  59
  60 * union
  61
  62 Support sophisticated collision handling when building a union: honor
  63 per-package priorities, etc.
  64
  65 * add GUIX_ALLOW_EXPENSIVE_TESTS
  66
  67 Tests that need to download stuff or otherwise take a long time would only be
  68 run when that is defined.
  69
  70 * guix build utils
  71 ** MAYBE Change ‘ld-wrapper’ to add RPATH for libs passed by file name
  72
  73 ** MAYBE Add equivalent to chrpath that uses [[https://gitorious.org/guile-dlhacks/guile-dlhacks/][guile-dlhacks]]
  74
  75 ** MAYBE Add a hash-rewriting thing for deep dependency replacement without rebuild
  76
  77 See [[https://github.com/NixOS/nixpkgs/commit/d1662d715514e6ef9d3dc29f132f1b3d8e608a18][Shea Levy's `replace-dependency' in Nixpkgs]].
  78
  79 * distro
  80 ** port to GNU/Hurd, aka. ‘i686-gnu’
  81
  82 Problems include that current glibc releases do not build on GNU/Hurd.
  83 In addition, there haven’t been stable releases of GNU Mach, MiG, and
  84 Hurd, which would be a pre-condition.
