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