[SKiDL BUG] 1.2.0 doesn't work with the previous files

[HubertHQH]

Describe the bug SKidl 1.2.0 doesn't work with the previous py files. With the old skidl, the py file can run and generate netlist successfully.

Traceback (most recent call last):

To Reproduce Steps to reproduce the behavior:

1. Install the latest Skidl 1.2.0
2. Set environment variable: "KICAD_SYMBOL_DIR=D:\Program Files\KiCad\6.0\share\kicad\symbols"
3. Run the following code:

from skidl import *

# Define components
in_terminal = Net('IN')
out_terminal = Net('OUT')
gnd = Net('GND')
regulator = Part('Regulator_Linear', 'LM1117-3.3', footprint = 'Package_TO_SOT_THT:TO-220-3_Vertical')
cap1 = Part('Device', 'C', value='10uF', footprint = 'Resistor_SMD:R_0805_2012Metric')
cap2 = Part('Device', 'C', value='1uF', footprint = 'Resistor_SMD:R_0805_2012Metric')

# Connect components
in_terminal += regulator['VI']
out_terminal += regulator['VO']
gnd += regulator['GND']
cap1[1] += in_terminal
cap1[2] += gnd
cap2[1] += out_terminal
cap2[2] += gnd

# Set regulator parameters
regulator.value = 'LM1117MP-3.3'

# Generate netlist
generate_netlist()

4. See error

Expected behavior Netlist is generated correctly without error.

Desktop :

• Windows 10
• Python version: 3.11
• SKiDL version [1.2.0]

Additional context I also tried the example file in readme and get the same issue. But both files work with the previous version Skidl. Suspect this is environment setting issues or related to KiCad symbol version? Previous Skidl only works with Kicad 6 symbols but not K7. Any idea?

Thanks for the report! There was an issue with search reported a few days ago that involved the is_url function. Try the development branch and see if that corrects your problem:

pip install git+https://github.com/devbisme/skidl.git@development

[HubertHQH]

Thanks Dave! The development branch addresses my issue. But when I try to generate_schematic(), there's another exception. This is a separate issue. I will dig deeper.

Traceback (most recent call last):

    return self.__getattribute__("fields")[key]
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^
KeyError: 'x'

During handling of the above exception, another exception occurred:

Are you trying to create a schematic? Are you trying to create a schematic while using KiCad 6 or 7 symbols? That won't work. Schematic creation currently only works with KiCad 5 symbol libraries.

[HubertHQH]

Aha, it's KiCad 5 symbol related. Now everything is fine. Thanks Dave!
