XDG MIMETYPES!!! ‚Äč

Another venture of mine that took many hours.

Set the following in home.nix or your home-manager configuration file.

INFO

You don't need to make the .desktop files, they are automatically found by NixOS. Their name wil almost always be the applications command and then append .desktop.

      defaultApplications = {
        "inode/directory" = ["pcmanfm.desktop"]; # Directories
        "text/plain" = ["emacsclient.desktop"]; # Plain text
        "application/vnd.openxmlformats-officedocument.wordprocessingml.document" = ["onlyoffice-desktopeditors.desktop"]; # .docx
