Additional context

• for loop or a list comprehension can be used to declare component arrays

@mtkmodel Component begin
        @structural_parameters begin
            N = 2
        end
        @components begin
            comprehension = [SubComponent(sc = i) for i in 1:N]
            written_out_for = for i in 1:N
                sc = i + 1
                SubComponent(; sc)
            end
            single_sub_component = SubComponent()
        end
    end

• Extend Base.parentmodule for Model

Note: As of ce7eed0, we have a MyMockModule module (with a component in it) defined, which could be used for this test.

ModelingToolkit.jl/test/model_parsing.jl

Lines 11 to 32 in ce7eed0

	module MyMockModule
	using ..ModelingToolkit, ..Unitful
	export Pin
	@connector Pin begin
	v(t), [unit = u"V"] # Potential at the pin [V]
	i(t), [connect = Flow, unit = u"A"] # Current flowing into the pin [A]
	@icon "pin.png"
	end
	@mtkmodel Ground begin
	@components begin
	g = Pin()
	end
	@icon read(abspath(ENV["MTK_ICONS_DIR"], "ground.svg"), String)
	@equations begin
	g.v ~ 0
	end
	end
	end
	using .MyMockModule

Rebase?

In addition to above mentioned details, new tests are added to check that conditionally component arrays can be defined: e324633.
