How can I record a macro

ehawker

If I want to select a shape (say Metal1), copy it to a different layer (say Via1), and go edit->selection->size shapes, to size it down by 1um, is there a way to show the command lines somewhere so that I can record this series of operations and put the codes into a Ruby macro?

Sorry I am fairly new to scripting. So instead of going through the lengthy API document, I am hoping to find an easier way to learn the command line scripts.

Thanks

Here is what I have so far, with questions embedded

app = RBA::Application::instance
mw = app.main_window
view = mw.current_view
mw.cancel

sel = view.object_selection

How do I apply the menu command to the slected object?

mw.menu.action("edit_menu.copy").trigger
mw.menu.action("edit_menu.paste").trigger
mw.menu.action("edit_menu.selection_menu.size").trigger

How do I pre-enter the size parameter?

mw.menu.action("edit_menu.selection_menu.change_layer").trigger

How do I specify the layer?

Hi,

the menu functions route to the internal implementation. There is no way to access the details by script, because scripts provide only some kind of "side entrance" rather than mapping the basic API. Hence, there is no recording. On the other hand, the API offers access to functionality for which there isn't a UI.

Scripting works on a different level: for example, you would not copy/paste, but rather work with the data objects (in your case: collect the polygonized shapes in a RBA::Region object). There is a lot to say about this, but that requires a deeper understanding of the API. I'm sorry, but the deal with open source is that you either accept it the way it is or contribute (or sponsor) an enhanced implementation.

Here is the "API style" solution I think you are looking for. It lacks handling of some errors (e.g. no layout loaded etc.), but basically it should work:

cv = RBA::CellView.active
ly = cv.layout

# TODO: replace target layer (here: GDS layer 8, datatype 0)
target_layer = ly.layer(8, 0)

res = RBA::Region::new

lv = RBA::LayoutView.current
lv.each_object_selected do |sel|
  if !sel.is_cell_inst?
    res.insert(sel.shape.polygon.transformed(sel.trans))
  end
end

# TODO: insert size value in DBU units
size_value = -10 

res.size(size_value)

lv.transaction("Size and copy selected objects")
begin
  cv.cell.shapes(target_layer).insert(res)
ensure
  lv.commit
end

This works. And it's so concise. I love it. Thank you Matthias!
