python 2 compatibility

[joamatab]

Thank you Alex for sharing Klayout_ipc!

Im getting the same error message both in Ubuntu and Mac, after installing the salt package I get

/Users/joaquin/.klayout/salt/klayout_ipc/python/lyipc/init.py:31: invalid syntax
/Users/joaquin/.klayout/salt/klayout_ipc/pymacros/start.lym:4

SyntaxError: invalid syntax

Im using python2 and klayout-0.25.3-macOS-HighSierra-1-Qt5101mp

the error got solved with python3 version of klayout for the server
klayout-0.25.3-macOS-HighSierra-1-Qt5101brew-Py364-9708d35.dmg (macOS 10.13 - Homebrew, Python 3)

and pip3 install for the client

Hi @joamatab, thanks for testing it out.

I think python 2 will be feasible. The trick is that PyQt5 does not install in python 2 as readily as it does with python 3. The client side socket would have to be rewritten to use the regular "socket" package, which I think is a good goal anyways to remove the PyQt dependency. I tried writing the server with "socket," and klayout's Qt did not like that for some reason.
