Example that violates KISS (Was: Focus on Prolog language is better than focus on Prolog engine)

Hi,
Example that violates KISS:
https://prolog-lang.org/ImplementersForum/0105-write-options.html
In Novacore, I have only introduced two new
write options priority/1 and format/1. They are
releavant for answer substitution display
and listing/1 formatting.
My deepest whish is for example to have
format/1 not as part of the core write options.
But this is very difficult to archive.
Should listing/1 sit in its own library,
and have a clone of the write routine? Its
easier to enhance the existing write routine
in the core and add some format/1 logic,
than have two write routines.
Quite a annonying problem to solve this
separation of concern. But maybe I should try
again, and can move listing/1 together with
format/1 write option into a separate library
that is not part of the core? Who knows...
Bye
P.S.: Some Prolog systems have do not have a listing/1
implementation. Try doing listing/1 in Scryer Prolog,
last time I looked they didn't have such a built-in.

Hi,
 How good does the GNU Prolog Novacore adapter
score? It scores more badly in the test suite
that tests the libraries since it also tests the
 web client and server functionality:
 Folder    gnu    j    js    py    cnt
calculate    42    136    136    136    136
common    88    175    175    173    175
extend    117    134    134    133    134
Total    247    445    445    442    445
 But the GNU Prolog Novacore adapter fares
quite well in the core testing itself, where
not some libraries are tested:
 Folder    gnu    j    js    py    cnt
arithmetic    215    225    224    224    225
control    159    171    171    171    171
extra    45    127    127    123    127
stream    62    84    83    84    85
structure    222    229    229    229    229
Total    703    836    834    831    837
 Bye

Dogelog Player tries to do something else with its
Novacore. It tries to minimize the Prolog language

P.S.: Also with novacore its very hard. I wrote an
Novacore adapter for GNU Prolog:

But Unicode is part of Novacore.

That Unicode even enters these discussions is a joke.  I'll just end up writing my own Prolog engine: a GPL-licensed Prolog engine in JS/Wasm, and an open project proper.  Or maybe I'll just switch to Mizar...  You stay tuned: next black Friday.
