// sway has a defined ordering of workspaces that should be preserved in
// the representation displayed by waybar to ensure that commands such
// as "workspace prev" or "workspace next" make sense when looking at
// the workspace representation in the bar.
// Due to waybar's own feature of persistent workspaces unknown to sway,
// custom sorting logic is necessary to make these workspaces appear
// naturally in the list of workspaces without messing up sway's
// sorting. For this purpose, a custom numbering property is created
// that preserves the order provided by sway while inserting numbered
// persistent workspaces at their natural positions.
//
// All of this code assumes that sway provides numbered workspaces first
// and other workspaces are sorted by their creation time.
//
// In a first pass, the maximum "num" value is computed to enqueue
// unnumbered workspaces behind numbered ones when computing the sort
// attribute.

//
// We cannot rely on the "num" property as provided by sway
// via IPC, because persistent workspace might not exist in
// sway's view. However, we need this property also for
// not-yet created persistent workspace. As such, we simply
// duplicate sway's logic of assigning the "num" property
// into waybar (see convertWorkspaceNameToNum). This way the
// sorting should work out even when we include workspaces
