ONLYOFFICE

ONLYOFFICE is a software suite that offers online and offline tools for document editing, collaboration, and management. It is developed by Ascensio System SIA, a company based in Riga, Latvia. ONLYOFFICE consists of several components, such as Docs, Workspace, Desktop Editors, and Mobile Apps. It is an open-source project that aims to provide a secure and compatible alternative to other office suites.

Installation

Add following line to your configuration to enable ONLYOFFICE

❄︎ /etc/nixos/configuration.nix

environment.systemPackages = [ pkgs.onlyoffice-desktopeditors ];

Troubleshooting

Install and use missing corefonts

According to one upstream bug ONLYOFFICE is unable to locate font files on NixOS.

Currently, the best workaround to add all fonts on your NixOS system is given as follows:

# onlyoffice-font-fix.nix

{ config, pkgs, ... }:

{
  # Expose installed fonts under /run/current-system/sw/share/X11/fonts
  fonts.fontDir.enable = true;

  # OnlyOffice font fix
  nixpkgs.overlays = [
    (final: prev: {
      onlyoffice-desktopeditors = prev.buildFHSEnv (
        prev.onlyoffice-desktopeditors.passthru.args
        // {
          extraBwrapArgs = (prev.onlyoffice-desktopeditors.passthru.args.extraBwrapArgs or [ ]) ++ [
            # Bind mount host system fonts into the FHS container's /usr/share/fonts:
            "--ro-bind"
            "/run/current-system/sw/share/X11/fonts"
            "/usr/share/fonts"
          ];
        }
      );
    })
  ];
}

Another workaround is to install missing or additional fonts and copy them to the user directory

❄︎ /etc/nixos/configuration.nix

# Allow installation of unfree corefonts package
nixpkgs.config.allowUnfreePredicate = pkg:
  builtins.elem (lib.getName pkg) [ "corefonts" ];

fonts.fonts = with pkgs; [
  corefonts
];

$ mkdir -p ~/.local/share/fonts
$ # Query store path to the corefonts package
$ NIXPKGS_ALLOW_UNFREE=1 nix-store --query --outputs $(nix-instantiate '<nixpkgs>' -A corefonts)
$ # Change the store path according to result of the command above
$ cp /nix/store/ssw7d3cl2dzps6y1c88c01xclsigmjqf-corefonts-1/share/fonts/truetype/* ~/.local/share/fonts/
$ chmod 644 ~/.local/share/fonts/*
