Ok, this clarify.
I try make much components “manually”. I compare this with PADS: It is easy way modify symbol and footprints in Ascii-form.
Eg. I want make a set of resistors and capacitors. Now we must go to philosophical side. It is several way make projects. Eg. capacitor. One man take Generic Capacitor, put it to schematic, and edit footprint, value, etc etc etc inside schematic. Then this man copy this capacitor and modify it data. Second way is make own symbol for every different capacitor: so, from my symbol library found cap_cer_smd_100n-50V-X7R-1%-0603, cap_cer_smd_10n-100V-X7R-1%-0603, etc etc etc. I love this way reason I make it work one time, and then I found it from library. Without errors.
So, this “kicad-library-generator” make just this work: I can make a large quantity components this way.
Second way is open kicad_sym in text editor:
(kicad_symbol_lib (version 20211014) (generator kicad_symbol_editor)
(symbol "CAP_SMD_CER_15pF-50V-5%-COG0603" (pin_names (offset 1.016)) (in_bom yes) (on_board yes)
(property "Reference" "C2" (id 0) (at -2.54 6.096 90)
etc etc etc
Copy&paste all this, and edit manually all texts. But. If I make this way, it is really same work I open symbol in symbol editor, edit data, SAVE AS. Edit, SAVE AS new name etc.
So, this is reason why this type tool “kicad-library-generator” is good. But, I try contact editor…
