* Workflow
  1. Load [[file:work.el][work.el]].
     #+BEGIN_SRC elisp :results none
(load-file "~/Candies/Sites/work/work.el")
     #+END_SRC

  2. Open [[file:index.org][index.org]] and publish the current project.

  3. Remove all timestamps.
     #+BEGIN_SRC elisp :results none
(org-publish-remove-all-timestamps)
     #+END_SRC

  4. Reopen [[file:index.org][index.org]] and republish the current project to get the
     updated timestamp, or run the following snippet:
     #+BEGIN_SRC elisp :results silent
(org-publish-project "work-site")
     #+END_SRC

  5. Go to https://entrepot.ibisc.univ-evry.fr/ and upload the files
     and directories from [[file:www/][www/]] to the folder =ivanov-page-perso=.

     The username to login to the entrepôt is
     =prénom.nom@ibisc.univ-evry.fr=, and the password is the same one
     as for the Intranet IBISC.  Detailed information [[https://intranet.ibisc.univ-evry.fr/projects/intranet/wiki/Entrep%C3%B4t_de_fichiers_Installation][here]].

  The following source code block is a shortcut for reloading the
  configuration, removing the timestamps, and publishing the
  whole site.
  #+BEGIN_SRC elisp :results silent
(load-file "~/Candies/Sites/work/work.el")
(org-publish-remove-all-timestamps)
(org-publish-project "work-site")
  #+END_SRC

* Seafile problem <2020-02-17 Mon>                                      :old:
** Problem
   After another update, Seafile started telling me this when I tried
   to start it:
   #+BEGIN_QUOTE
   qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
   This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

   Aborted (core dumped)
   #+END_QUOTE

   I did a couple hours of searching, and found some threads, which did
   not help:

   - https://github.com/NixOS/nixpkgs/issues/42893

     Idea: imperatively install Seafile and then tell it where to
     search for plugin:
     #+BEGIN_SRC shell
nix-env -iA nixpkgs.qt5.qtbase
export XDG_DATA_DIRS=$HOME/.nix-profile/share:$XDG_DATA_DIRS
     #+END_SRC
     Tried this literally, got
     #+BEGIN_QUOTE
     error: attribute 'nixpkgs' in selection path 'nixpkgs.qt5.qtbase' not found
     #+END_QUOTE

   - https://github.com/NixOS/nixpkgs/issues/65399

     There is a new way to describe Qt packages which correctly handles
     looking for plugins, this issue is there to help track all the
     problems that this may lead to.  There is [[https://hydra.nixos.org/build/96804884/download/1/nixpkgs/manual.html#sec-language-qt][some documentation]] as to
     how to do it properly.  I didn't feel like hacking Nixpkgs right
     away.

   - https://forum.qt.io/topic/111553/solved-qt-qpa-plugin-could-not-find-the-qt-platform-plugin-xcb-in/7

     Tell Seafile where to look for plugins.  This is not necessarily
     even applicable with Nix.

   - https://github.com/haiwen/seafile/issues/6

     Apparently, Seafile has a CLI interface, but I don't find it in
     my installation.  More concretely, the file =seafile-cli= appears
     in shell completions, but it doesn't launch nor could I find
     where it was.

** My hack <2020-02-17 Mon>
   My current hack consists in the following modifications:

   1. Add =qt5.qtbase= and =seafile-client= to =home.packages= in
      [[/home/scolobb/.config/nixpkgs/home.nix][=home.nix=]].

   2. Install =seafile-shared= instead of =seafile-client= in
      [[file:shell-seafile.nix][=shell-seafile.nix=]].

   Very weirdly, this makes =seafile-applet= work.  I tried not doing
   (1) and putting all the packages in [[file:shell-seafile.nix][=shell-seafile.nix=]], but it
   won't work.  Also, again weirdly, outside of Nix shell the
   =seafile-applet= coming from the home-manager installation never
   gets past the message
   #+BEGIN_QUOTE
   lang = English, translation = (null), locale.name() = en_US
   #+END_QUOTE
   without showing the interface or doing whatsoever.

** Proper solution?
   A proper solution would probably consist in updating the Seafile
   package to comply with the new [[https://hydra.nixos.org/build/96804884/download/1/nixpkgs/manual.html#sec-language-qt][way to describe Qt packages]].

* Removing the publish cache
  Org-publish will not detect files being deleted from the output.  To
  force it to clear its caches, do the following:
  #+BEGIN_SRC elisp
    (org-publish-remove-all-timestamps)
  #+END_SRC

* Possible colors for the banner
  #+BEGIN_SRC css
    background-color: azure;
    background-color: lightcyan;
    background-color: paleturquoise;
  #+END_SRC
