KLayout Python module as a websockets client

NOTE: this is a demonstrator. It shows the basic idea, but lacks fancy styling and many potential features. It does not use any JavaScript libraries and only plain CSS.

Getting the KLayout Python module

You will need a KLayout Python module with Qt-less canvas enabled.

To build the module yourself, clone KLayout from

$ git clone git@github.com:KLayout/klayout.git

You will need Linux and the following libraries: curl, zlib, png, expat and python3.

In the klayout sources, run

$ python3 setup.py build

Once the respective version (0.28) is available in PyPI, you can simply do

pip3 install klayout

Usage

Clone this repository somewhere else:

git clone git@github.com:klayoutmatthias/canvas2canvas.git canvas2canvas

In this project, start the server:

./server.py

You may need to point "PYTHONPATH" to the directory where you built the Python module. In my case this is:

export PYTHONPATH=/home/matthias/klayout/master/build/lib.linux-x86_64-3.8

In a different window, start a browser (tested with Firefox) and load "client.html" from this project, e.g. "firefox client.html".
