Is there a way to refer "not primary" servers in cap v3?

[Carlos Peñas]

on capistrano V3 there's:

roles(:role) For all servers

and

primary(:role) for the first server in a role

Is there a way to refer "the servers which aren't primary" in a similar way? Or I am forced to use server properties?

try (roles(:role) - primary(:role)), they are Ruby enumerables, so it might work :)

Almost!

Seems that primary returns a Capistrano::Configuration::Server and not an enumerable (at least in 3.4.0) so that hack do not work. But it helped me to reach

on (roles(:app) - [primary(:app)]) do

which work as expected

see:

[4] pry(main)> primary(:app)
=> #<Capistrano::Configuration::Server:0x007f2a421d3ee0
 @hostname="127.0.0.1",
 @port=nil,
 @properties=#<Capistrano::Configuration::Server::Properties:0x007f2a421d3a58 @properties={}, @roles=#<Set: {:app}>>,
 @user="carlos">
[5] pry(main)> roles(:app) - [primary(:app)]

=> [#<Capistrano::Configuration::Server:0x007f2a421d38f0
  @hostname="127.0.1.1",
  @port=nil,
  @properties=#<Capistrano::Configuration::Server::Properties:0x007f2a421d35a8 @properties={}, @roles=#<Set: {:app}>>,
