A convenience method which is same as follows:

  text ','
  breakable

A convenience method which is same as follows:

  group(1, '#<' + obj.class.name, '>') { ... }

Adds obj to the pretty printing buffer using Object#pretty_print or Object#pretty_print_cycle.

Object#pretty_print_cycle is used when obj is already printed, a.k.a the object reference chain has a cycle.

Adds a separated list. The list is separated by comma with breakable space, by default.

seplist iterates the list using iter_method. It yields each object to the block given for seplist. The procedure separator_proc is called between each yields.

If the iteration is zero times, separator_proc is not called at all.

If separator_proc is nil or not given, +lambda { comma_breakable }+ is used. If iter_method is not given, :each is used.

For example, following 3 code fragments has similar effect.

  q.seplist([1,2,3]) {|v| xxx v }

  q.seplist([1,2,3], lambda { comma_breakable }, :each) {|v| xxx v }

  xxx 1
  q.comma_breakable
  xxx 2
  q.comma_breakable
  xxx 3
