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.

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

To build the module yourself, clone KLayout from

$ git clone [email protected]: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

Clone this repository somewhere else:

git clone [email protected]: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".
