Klayout PyCell integration

[ThomasZecha]

-Re-implemented clone() for shapes using deepcopy
-Implemented tagging of shapes feature from SKILL Pcell counter-part
-Fixed npn13G2L/npn13G2V to be equal to SKILL Pcell counter-part
-Introduced library code/documentation as submodule from pycell4klayout-api repo

Good morning, one way I found to perform the integration is by going inside the folder "IHP-Open-PDK/ihp-sg13g2/libs.tech/klayout/tech/pymacros" and changing the Python code in the autorun.lym file to:

# This file only serves to bootstrap sg13g2_pycell_lib.
# Everything else is done inside this module's __init__.py.
import sys
sys.path.append('/IHP-Open-PDK/ihp-sg13g2/libs.tech/klayout/python')
import sg13g2_pycell_lib

@ThomasZecha definitely there is something wrong bootstrapping the submodule. I have got this when running klayout

ERROR: 
$PDK_ROOT/ihp-sg13g2/libs.tech/klayout/python/sg13g2_pycell_lib/__init__.py:23: ModuleNotFoundError: No module named 'cni.dlo'
$PDK_ROOT/ihp-sg13g2/libs.tech/klayout/python/sg13g2_pycell_lib/__init__.py:23

is it possible to reference just a specific submodule folder in the OpenPDK repo?
so that there will be cni folder in klayout/python/ from the pycell4klayout-api repo

[ThomasZecha]

Solution 1:
link klayout/python/cni -> klayout/python/pycell4klayout-api/source/python/cni/
Solution 2:
Add .../libs.tech/klayout/python/pycell4klayout-api/source to the KLAYOUT_PATH env

sys.path.append('/IHP-Open-PDK/ihp-sg13g2/libs.tech/klayout/python')
import sg13g2_pycell_lib

with this code:

import sys
import os
sys.path.append(os.environ['KLAYOUT_HOME'] + '/python/pycell4klayout-api/source/python')
import sg13g2_pycell_lib

it is working on my side
I'm anyway using this env variable to set the location of PDK specific data before starting KLayout, but I'm not sure if everybody does it the same
