Having issues running netlist_to_skidl

[shanzez]

Here is what I'm seeing:

netlist_to_skidl -i Interceptor.net -o Interceptor.py -w
Traceback (most recent call last):

    raise ParseException(instring, loc, self.errmsg, self)
pyparsing.ParseException: Expected W:(ABCD...), found '"'  (at char 17), (line:1, col:18)

I generated my netlist file from a recent nightly version of KiCad because the developer created it with a recent nightly.

Skidl 1.0.0. Python 3.9.5. On a Mac. KICAD_SYMBOL_DIR set. Just tried the same thing on a Debian Linux machine and got the same result. Is my netlist file bad?

Help would be appreciated.

If the line:1, col:18 refers to the Interceptor.net file, that line looks like this:

(export (version "E")

I removed the " from around E and then it fails with:

  File "/opt/homebrew/lib/python3.9/site-packages/pyparsing.py", line 4410, in parseImpl

Is my netlist just bad because of the KiCad nightly software perhaps?

Theoretically, the netlist file format should be the same between V5 and V5.99. Please send the netlist file and I'll take a look at it.

[shanzez]

I’m sorry, I cannot share our netlist as it is confidential. Guess I’m out of luck.

I have the same problem. I'm using KiCad 6 on Windows 10. I didn't set the KICAD_SYMBOL_DIR variable. Do you think this is the reason?

This is my input: netlist_to_skidl --input test.net --output blub.py

This is my output:

The KiCad 6 netlist format is probably the cause of the problem. I have a version of kinparse that parses KiCad 6 netlist files. You might try installing it to see if it fixes your problem:

pip install git+https://github.com/devbisme/kinparse@kicad6

Let me know if this fixes the problem or not. If not, I'll have to look at the problem in more detail.

[devbisme]

I found and fixed an error in kinparse. It should fix your problem. You can install it the normal way:

pip install -U kinparse

Hi Dave,

thanks for the swift response.

I'm getting a different response than before, after installing kinparse.

This is the error:
UnicodeEncodeError: 'charmap' codec can't encode character '\x89' in position 7856: character maps to <undefined>

It may be usefull to know, that I'm using KiCad 6 to generate the netlist. After a quick google search the character '\x89' seems to be some kind of indentation. Maybe it has to to with KiCad or I do something wrong on my part.
