Component definition list from Ruby vs SU window

[Pout]

I use this code to list all used component definition names:

def TESTXD.listcompnames1
		$componentnames=[]
		Sketchup.active_model.entities.each{|e|
			TESTXD.listcompnames2(e)
		}
		$componentnames.uniq!
		$componentnames.sort!
		puts ($componentnames)
	end
	def TESTXD.listcompnames2(e)
		theclass=e.class
		if theclass==Sketchup;;Group 
			gen=e.entities
			gen.each{|gent|
				TESTXD.listcompnames2(gent)
			}
		elsif theclass==Sketchup;;ComponentInstance
			$componentnames<<e.definition.name
			e.definition.entities.each{|ent|
				TESTXD.listcompnames2(ent)
			}
		end
	end

This gives me a list in the ruby console.
Now if I compare this list with the list shown in the components windows I see that certain definitions are available in ruby but not in the components window.

Is this due to the fact that those component definitions are only used in nested component definitions? That makes no sense.
Or maybe I'm missing something.

ok, hitting 'Expand' would be a good idea

If you have a lot of model entities, duplicate instances etc it can take a while to sift through it all.
It's quicker to iterate the model.definitions and compile lists of 'names' [or references] for all groups, components, used-components, unused-components and images thus

defs=Sketchup.active_model.definitions
groups=[]; group_defs=[]; group_refs=[]; images=[]
compo_names=[]; used_compo_names=[]; unused_compo_names=[]
compo_refs=[]; compos_instances=[]
compos_instances_names=[]; compos_instances_refs=[]
defs.each{|d|
  if d.image?
    images << d.name
  elsif d.group?
    groups << d.instances[0].name
    group_defs << d
    group_refs << d.instances
  else ### compo
    compo_names << d.name
    if d.instances[0]
      used_compo_names << d.name
    else ### unused
      unused_compo_names << d.name
    end
    compo_refs << d
    compo_instances << d.instances
    ins=[]; d.instances.each{|i|ins << i.name}
    compo_instances_names << [d.name, ins]
    compo_instances_refs << [d, d.instances]
  end
}

Choose which data you want to extract for later use...

Note that the DefinitionList include groups and images as well. As TIG mentioned, some components are hidden by default in SketchUp's Component Browser - sub-component of imported models for instance. They are marked with ComponentDefinition.internal?.

great, thank you both for the information!
