https://github.com/russdill/pybis

has the following comment:

" ibs2symdef.py - Convert the components in an IBIS file to a djboxsym
symdef
file"

and the ibis format specification now seems to reside at:

https://ibis.org/ver5.0/ver5_0.txt

if all that people want is a symbol with the pin labels from the ibis file,
it doesn't look _too_ hard to do, the caveat being that some pins don't
necessarily get listed/labelled, and the pin count seems to be specified in
the ? optional package .pkg +/- alternative .pkg files, i.e.

[Number Of Pins]   128

I could probably modify the kicad library (symbol) to gschem symbol
converter's parser to cope with ibis text definitions, and put this on the
to-do list, if someone wants a command line java option as well as the
existing python->perl option.

Cheers,

Erich.

here's a snippet from the ver5_0.txt document linked to above ( "|" seems
to be their comment flag):
