#+TITLE: What's left to do?
#+STARTUP: content hidestars

* MAYBE Add a substituter that uses the GNUnet DHT or [[http://libswift.org][libswift]]

Would be neat if binaries could be pushed to and pulled from the GNUnet DHT or
rather libswift (since DHTs aren’t suited for large payloads).  Guix users
would sign their binaries, and define which binaries they trust.

Use UPnP and similar to traverse NAT, like ‘filegive’ does.

* user interface
** add guile-ncurses interface

* extend <package>
** add ‘recommends’ field

For instance, glibc, binutils, gcc, and ld-wrapper would recommend each other.
‘guix package -i’ could ask interactively (?), or allow users to follow all or
none of the recommendations.

** add a ‘user-environment-hook’

This should specify builder code to be run when building a user
environment with ‘guix-package’.  For instance, Texinfo’s hook would
create a new ‘dir’.

** extend ‘propagated-build-inputs’ with support for multiple outputs

#+BEGIN_SRC scheme
  (outputs '("out" "include"))
  (propagated-build-inputs
    `(((("i1" ,p1 "o1")
        ("i2" ,p2))
       => "include")
      ("i3" ,p3)))
#+END_SRC

* synchronize non-GNU package descriptions with the [[http://directory.fsf.org][FSD]]

Meta-data for GNU packages, including descriptions and synopses, can be
dumped from the FSD:
http://directory.fsf.org/wiki?title=GNU/Export&action=purge .
We could periodically synchronize with that.

* add a guildhall build system

The Guildhall is Guile’s packaging system.  It should be easy to add a
‘guildhall-build-system’ that does the right thing based on guildhall
recipes.

* union

Support sophisticated collision handling when building a union: honor
per-package priorities, etc.

* add GUIX_ALLOW_EXPENSIVE_TESTS

Tests that need to download stuff or otherwise take a long time would only be
run when that is defined.

* guix build utils
** MAYBE Change ‘ld-wrapper’ to add RPATH for libs passed by file name

** MAYBE Add equivalent to chrpath that uses [[https://gitorious.org/guile-dlhacks/guile-dlhacks/][guile-dlhacks]]

** MAYBE Add a hash-rewriting thing for deep dependency replacement without rebuild

See [[https://github.com/NixOS/nixpkgs/commit/d1662d715514e6ef9d3dc29f132f1b3d8e608a18][Shea Levy's `replace-dependency' in Nixpkgs]].

* distro
** port to GNU/Hurd, aka. ‘i686-gnu’

Problems include that current glibc releases do not build on GNU/Hurd.
In addition, there haven’t been stable releases of GNU Mach, MiG, and
Hurd, which would be a pre-condition.

* Installer
** Fix impossibility to restart on error after cow-store has been started
See https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00161.html.
- Force reboot upon installer failure
- Unshare the installer process
- Run the installer process in a separate namespace
** Partitioning
*** Add RAID support
*** Add more partitioning schemes
The actual schemes are taken from Debian Installer but some are not
implemented yet: like "Separate partitions for /home /var and /tmp".
*** Replace wait page "Partition formating is in progress, please wait"
Create a new waiting page describing what's being done:

[              20%              ]
Running mkfs.ext4 on /dev/sda2 ...

[              40%              ]
Running mkfs.ext4 on /dev/sda3 ...
*** Add a confirmation page before formating/partitioning
** Desktop environments
*** Allow for no desktop environments
Propose to choose between "headless server" and "lightweight X11" in a new
page.
*** Add services selection feature
Add a services page to the configuration. Ask for services to be installed
like SSH, bluetooth, TLP in a checkbox list?
** Locale and keymap
*** Try to guess user locale and keymap by probing BIOS or HW (dmidecode)
** Timezone
*** Regroup everything in one single page
Under the form:
(UTC + 1) Europe/Paris
(UTC + 2) Africa/Cairo
...
** Display issue
*** Investigate display issue described here:
https://lists.gnu.org/archive/html/guix-devel/2019-01/msg00305.html
dovic Courtès 2020-05-14etc: indent-code.el: Use the --quick option....This prevents Emacs from loading the autoload definitions found in its profile, which needlessly clutters the output. It also prevents Geiser (if installed) from blocking the script and asking the user to input the Scheme implementation to use. The trick for passing multiple arguments to Emacs is to use what is called a "sesquicolon" (see https://www.emacswiki.org/emacs/EmacsScripts). * etc/indent-code.el.in: Rename to... * etc/indent-code.el: ...this. Adapt the shebang to use a sesquicolon, and pass the --quick option to Emacs. Since this line is interpreted by the shell, simply use Emacs from the PATH instead of from a hard coded location. (main): New procedure, used as the entry point. * configure.ac: Remove the warning about Emacs. Emacs can now be installed any time by the user if they want to use the script. * .gitignore: No longer ignore changes to etc/indent-code.el. Maxim Cournoyer 2020-04-23build: Don't build man pages when cross-compiling....* configure.ac: Define 'CROSS_COMPILING' Automake conditional. * doc/local.mk (dist_man1_MANS): Wrap in "if !CROSS_COMPILING". Ludovic Courtès 2020-03-11build: Require Guile 2.2.3 or later....* configure.ac: For 2.2.x, require 2.2.3 or later. Ludovic Courtès 2020-01-17build: Allow builds with Guile 3.0....* configure.ac: Add "3.0" in 'GUILE_PKG' invocation. * doc/guix.texi (Requirements): Mention 3.0.x. Ludovic Courtès 2019-11-09build: Warn about etc/indent-code.el when Emacs is absent....* configure.ac: Warn when 'emacs' is not found, and emit 'etc/indent-code.el' otherwise. Signed-off-by: Ludovic Courtès <ludo@gnu.org> zimoun 2019-07-25maint: Switch to Guile-JSON 3.x....Guile-JSON 3.x is incompatible with Guile-JSON 1.x, which we relied on until now: it maps JSON dictionaries to alists (instead of hash tables), and JSON arrays to vectors (instead of lists). This commit is about adjusting all the existing code to this new mapping. * m4/guix.m4 (GUIX_CHECK_GUILE_JSON): New macro. * configure.ac: Use it. * doc/guix.texi (Requirements): Mention the Guile-JSON version. * guix/git-download.scm (git-fetch)[guile-json]: Use GUILE-JSON-3. * guix/import/cpan.scm (string->license): Expect vectors instead of lists. (module->dist-name): Use 'json-fetch' instead of 'json-fetch-alist'. (cpan-fetch): Likewise. * guix/import/crate.scm (crate-fetch): Likewise, and call 'vector->list' for DEPS. * guix/import/gem.scm (rubygems-fetch): Likewise. * guix/import/json.scm (json-fetch-alist): Remove. * guix/import/pypi.scm (pypi-fetch): Use 'json-fetch' instead of 'json-fetch-alist'. (latest-source-release, latest-wheel-release): Call 'vector->list' on RELEASES. * guix/import/stackage.scm (stackage-lts-info-fetch): Use 'json-fetch' instead of 'json-fetch-alist'. (lts-package-version): Use 'vector->list'. * guix/import/utils.scm (hash-table->alist): Remove. (alist->package): Pass 'vector->list' on the inputs fields, and default to the empty vector. * guix/scripts/import/json.scm (guix-import-json): Remove call to 'hash-table->alist'. * guix/swh.scm (define-json-reader): Expect pair? or null? instead of hash-table?. [extract-field]: Use 'assoc-ref' instead of 'hash-ref'. (json->branches): Use 'map' instead of 'hash-map->list'. (json->checksums): Likewise. (json->directory-entries, origin-visits): Call 'vector->list' on the result of 'json->scm'. * tests/import-utils.scm ("alist->package with dependencies"): New test. * gnu/installer.scm (build-compiled-file)[builder]: Use GUILE-JSON-3. * gnu/installer.scm (installer-program)[installer-builder]: Likewise. * gnu/installer/locale.scm (iso639->iso639-languages): Use 'assoc-ref' instead of 'hash-ref', and pass vectors through 'vector->list'. (iso3166->iso3166-territories): Likewise. * gnu/system/vm.scm (system-docker-image)[build]: Use GUILE-JSON-3. * guix/docker.scm (manifest, config): Adjust for Guile-JSON 3. * guix/scripts/pack.scm (docker-image)[build]: Use GUILE-JSON-3. * guix/import/github.scm (fetch-releases-or-tags): Update docstring. (latest-released-version): Use 'assoc-ref' instead of 'hash-ref'. Pass the result of 'fetch-releases-or-tags' to 'vector->list'. * guix/import/launchpad.scm (latest-released-version): Likewise. Ludovic Courtès 2019-05-06Add (guix lzlib)....* guix/lzlib.scm, tests/lzlib.scm: New files. * Makefile.am (MODULES): Add guix/lzlib.scm. (SCM_TESTS): Add tests/lzlib.scm. * m4/guix.m4 (GUIX_LIBLZ_LIBDIR): New macro. * configure.ac (LIBLZ_LIBDIR): Use it. Define and substitute 'LIBLZ'. * guix/config.scm.in (%liblz): New variable. * guix/self.scm (make-config.scm): Add TODO comment. Co-authored-by: Ludovic Courtès <ludo@gnu.org> Pierre Neidhardt 2019-04-17build: No longer substitute 'LIBGCRYPT'....This had become useless since ca719424455465fca4b872c371daf2a46de88b33. * configure.ac (LIBGCRYPT): Remove. * guix/config.scm.in (%libgcrypt): Remove.
