Looks like the format they use is basically INI but with JSON values... https://github.com/pimutils/vdirsyncer/blob/079a156bf82fe86173d0d05ec0937703b5c6a735/vdirsyncer/cli/config.py#L151

So like,

settingsFormat = {
  type = types.attrsOf (types.attrsOf (pkgs.formats.json {}).type);
  generate = name: value: pkgs.writeText name (lib.generators.toINI {
    mkKeyValue = lib.generators.mkKeyValueDefault {
      mkValueString = builtins.toJSON;
    } " = ";
  } value);
};

let
quoteStr = s: ''"${s}"'';
mkKeyValue = name: value: "${name} = ${mkValue value}";
mkValue = value:
if builtins.isList value then
"[${concatStringsSep ", " (map mkValue value)}]"
else if builtins.isString value then
quoteStr value
else
(toString value);
mkSection = title: val: ''
[${title}]
${concatStringsSep "\n" (mapAttrsToList mkKeyValue val)}
'';
in concatStringsSep "\n" (mapAttrsToList mkSection settings);
cfgFile =
pkgs.writeText "vdirsyncer.conf" (formatToUnknownFormat cfg.settings);
in {
options.services.vdirsyncer = {
enable = mkEnableOption "synchronization of calendars";

Needs a description, default value and better type (see above)

configFile = mkOption {
type = types.path;
default = cfgFile;
};
onBootSec = mkOption {
type = types.str;
default = "15min";
};
onUnitActiveSec = mkOption {
type = types.str;
default = "30min";
};

These need descriptions. I'd also get rid of configFile for now, unless there's a good reason to have it.

};

config = mkIf cfg.enable {
systemd.user.timers.vdirsyncer = {
Unit = { Description = "Timer to synchronize calendars"; };

Timer = {
OnBootSec = cfg.onBootSec;
OnUnitActiveSec = cfg.onUnitActiveSec;
};

Install.WantedBy = [ "timers.target" ];
};

systemd.user.services.vdirsyncer = {
Unit = {
Description = "Synchronize your calendars";
After = [ "network-online.target" ];

Service = {
ExecStart = "${pkgs.vdirsyncer}/bin/vdirsyncer -c ${cfgFile} sync";

We probably want to do metasync as well as sync.

as mentioned here: #3982 (comment)

we should probably do vdirsyncer discover before sync and metasync
