Cadsoft Eagle with Python Scripting

e14 Contributor

Hi,

 

I've only started using Eagle a few weeks ago, and as much as I like it, I have found what I consider some pretty fundamental features just missing. As the built in scripting language is extremely restrictive (when compared to a 'real' language like python, lua or ruby), I made an attempt to get python running with Eagle.

 

http://www.youtube.com/watch?v=_w7CECR7Dv8

 

The above is a video of a project I have been working on for the pas 3-4 days, which basically involves exposing the Cadsoft ULP and SCR to python (albeit in not the fastest way). But it does allow me to now use 90% of the ULP and all of the SCR directly from python, including the Object Heirarchies, board.grid... schematic... which have all be exposed in a pythonic way.

 

as an example, to get all the Instances in the schematic..

 

instances = Eaglepy.ULSchematic().instances()

 

or loop,

 

for instance in Eaglepy.ULSchematic().instances():

     print instance.name()

 

etc..

 

The tools in the video were very quick to knock out.. the slowest bit was figuring out the papers for approximating cubic/quadratic bezier curves with arcs, for the DXF Importer. These should be the first of many tools to come, next on the list is a group manager so I can save my selectsion.

 

Hopefully when I have had time to test this a bit more I will release the code to the community, along with any tools I have built. for others who might want this funtionality. (something that should be out of the box with proper bindings to a proper language imo...)

 

Cheers

 

Rob.

    For things like graphics, hardware interfacing, file formats,

    networking, GUIs etc. I found that development at the interpreter console

    provides the biggest boost in productivity.

     

    Yes!  It's quite fun to use pyqt from the ipython prompt to interactively

    show and hide or manipulate various parts of my GUI.

     

    You can do similar things with various JVM languages that have REPLs.  For

    example, here's some Scala typed into the Ammonite REPL to create a popup

    window with a single button:

     

     

    @ {

      import javax.swing._, java.awt.event._

      val frame = new JFrame("Hello World Window")

     

      val button = new JButton("Click Me")

      button.addActionListener(new ActionListener{

        def actionPerformed(e: ActionEvent) = button.setText("You clicked the

    button!")

      })

      button.setPreferredSize(new java.awt.Dimension(200, 100))

      frame.getContentPane.add(button)

      frame.pack()

      frame.setVisible(true)

     

      }
