Load
work.el.(load-file "~/Candies/Sites/work/work.el") - Open
index.organd publish the current project. -
Remove all timestamps.
(org-publish-remove-all-timestamps) - Reopen
index.organd republish the current project to get the updated timestamp. - Go to https://entrepot.ibisc.univ-evry.fr/ and upload the files
and directories from www/ to the folder
ivanov-page-perso. The username to login to the entrepôt isprénom.nom@ibisc.univ-evry.fr, and the password is the same one as for the Intranet IBISC. Detailed information here.
Seafile problem <2020-02-17 Mon> old
Problem
After another update, Seafile started telling me this when I tried to start it:
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)
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:
nix-env -iA nixpkgs.qt5.qtbase export XDG_DATA_DIRS=$HOME/.nix-profile/share:$XDG_DATA_DIRSTried this literally, got
error: attribute 'nixpkgs' in selection path 'nixpkgs.qt5.qtbase' not found
- 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 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-cliappears 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:
- Add
qt5.qtbaseandseafile-clienttohome.packagesinhome.nix. - Install
seafile-sharedinstead ofseafile-clientinshell-seafile.nix.
Very weirdly, this makes seafile-applet work. I tried not doing
(1) and putting all the packages in 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
lang = English, translation = (null), locale.name() = en_US
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 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:
