Command Line/Batch mode

Hi All,
I need to instantiate a cell in a gds in another gds, under the top cell of this one at coordinate 0,0
I'm able to do it using the graphical interface but I would like to do without the gui.. using a script to run in the command line..

How to do it?

Thx,
Salvatore

One-liner:

RBA::CellView::active.cell.insert(RBA::CellInstArray::new(RBA::CellView::active.layout.cell("OTHERCELL").cell_index, RBA::Trans::new))

Multi-liner:

cv = RBA::CellView::active
child = cv.layout.cell("OTHERCELL")
inst = RBA::CellInstArray::new(child.cell_index, RBA::Trans::new)
cv.cell.insert(inst)

Hi Matthias,
is it possible to run the script without open the gui?
and how to define the two gds and the coordinates?

Thx,
Salvatore

I see ... by "run in command line" you mean "shell", not KLayout's command line ...

Here it is:

# run with 
#   klayout -b -rd file1=a.gds -rd file2=b.gds -rd out=a+b.gds -r merge.rb

puts "Reading #{$file1} .."
ly1 = RBA::Layout::new
ly1.read($file1)

puts "Reading #{$file2} .."
ly2 = RBA::Layout::new
ly2.read($file2)

# save the top cell - after creating a new cell there are two top cells
# and "ly1.top_cell" will fail.
ly1_top_cell = ly1.top_cell

# create a new cell in ly1 which will hold a copy of ly2's top cell
new_cell = ly1.create_cell(ly2.top_cell.name)

# copy over everything from ly2's top cell to the new cell
new_cell.copy_tree(ly2.top_cell)

# place the new cell in ly1's top cell
angle = 0  # (1 = 90, 2 = 180, 3 = 270 degree)
mirror = false
x = 0
y = 0
trans = RBA::Trans::new(angle, mirror, x, y);
ly1_top_cell.insert(RBA::CellInstArray::new(new_cell.cell_index, trans))

# save the result
puts "Writing #{$out} .."
ly1.write($out)
