Request: Return an ObjectInstPath from the RecursiveShapeIterator

[olcc]

Hello,
The RecursiveShapeIterator provides many details, including the instantiation path of the shape. However there is still some work and difficulty for the user in order to build an ObjectInstPath for the shape from these parameters.

I would appreciate if there existed a method RecursiveShapeIterator.opath() that would return a suitable ObjectInstPath object for the shape.

This would make it possible to build a selection more easily, when the shapes come from a RecursiveShapeIterator.

Hi Olivier,

I can't provide opath from RecursiveShapeIterator because that's crossing the db/GUI domain, but I can provide a ObjectInstPath constructor that takes an iterator and a cellview index.

As a quick workaround, you can define a corresponding constructor yourself. For example in Ruby:

module RBA

  class ObjectInstPath
    def ObjectInstPath.from_si(si, cv_index)
      oi = RBA::ObjectInstPath::new
      oi.top = si.top_cell.cell_index
      oi.cv_index = cv_index
      oi.clear_path
      si.path.each { |i| oi.append_path(i) }
      oi.shape = si.shape
      oi.layer = si.layer
      oi
    end
  end
  
end

Usage is like this:

lv = RBA::LayoutView::current
cv_index = lv.active_cellview_index

ly = lv.active_cellview.layout
top_cell = lv.active_cellview.cell

l2 = ly.layer(2, 0)

sel = []

lv.clear_object_selection

si = top_cell.begin_shapes_rec(l2)
while ! si.at_end?

  oi = RBA::ObjectInstPath::from_si(si, cv_index)
  lv.select_object(oi)

  si.next

end

I will provide a similar constructor natively then (it will be a variant of ObjectInstPath#new.

I think I understand what you explained.

This will be convenient, thank you.
