grammar for symbol and footprint library from digikey

[ganghuang]

I am new on using this KiBot.
After install the ver 0.11.0, I made an example yaml and change the name to myproject.kibot.yaml
Then I run
kibot -b myproject.kicad_pcb -c myproject.kibot.yaml
I got error on the
ERROR:At line 7 of digikey-kicad-library/digikey-symbols/dk_Ferrite-Beads-and-Chips.lib: Malformed component field (kibot.kiplot - kiplot.py:234)

The library is come from digikey provided great library for lots of components at https://github.com/Digi-Key/digikey-kicad-library.
They work in my kicad 5.1.9.

So I hack in the
/home/myname/.local/lib/python3.9/site-packages/kibot/kicad/v5_sch.py
and find the line 115 is
r'([LRCBT][IN][BN])\s*' # 8 VJustify+Italic+Bold
which does not allow space between the 'C N N'.
I added \s* in between
r'([LRCBT]\s*[IN]\s*[BN])\s*' # 8 VJustify+Italic+Bold
And that pass that check.

Then the problem shows up at
DEBUG:Loading doc-lib digikey-kicad-library/digikey-symbols/dk_Ferrite-Beads-and-Chips.dcm (kibot.kicad.v5_sch - v5_sch.py:703)

with this error message

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xae in position 455: invalid start byte

This time it goes beyond what I can do by myself.
I opened the dcm file mentioned above, and search for the 0xae or even any non ascii char, I didn't find it.

This time the error message does not tell me what happened enough for me to figure it out.
Can you help me on this?

Or even better try to get some more sample libraries from the digikey library and test if that works?

Thanks

Hi @ganghuang !

These files are really wrong and you should report it to the project maintainers.

1. The *.lib file uses C N N instead of CNN. KiCad never writes it as C N N and, even when you don't get an error, it doesn't work. I tried C I B and it didn't work, the italic and bold were ignored.
2. The *.dcm file is also wrong, the encoding for these files is UTF-8 and the file you mention contains invalid UTF-8. KiCad silently ignores these lines, just load these components in the library editor and you'll see the faulty components doesn't have keywords, even when you can see them in the file, but the problem is a stray 0xAE character (ISO-8859-1 registered mark symbol).

I'll add some tolerance to these errors, but the files are really corrupted.

I reported it to the original project, issues Digi-Key/digikey-kicad-library#162 and Digi-Key/digikey-kicad-library#163
