SWI-Prolog master not wide awake, doing day-sleeping (Was: Most radical approach is Novacore from Dogelog Player)

Hi,
Even the SWI-Prolog master not wide awake,
doing day-sleeping.

Maybe you didn’t notice this nifty detail.
Thats all you need:
 > The ISO core standard is silent about a flag back_quotes
 > Its more a naming problem. Have two libraries
library(portray_codes) and library(portray_chars),
Or one library(portray_text).
Just add one more rule:
user:portray(Chars) :-
     portray_text_option(enabled, true),
     '$skip_list'(Length, Chars, _Tail),
     portray_text_option(min_length, MinLen),
     Length >= MinLen,
     mostly_chars(Chars, 0.9),
     portray_text_option(ellipsis, IfLonger),
     quote2(C),
     put_code(C),
     maplist(char_code, Chars, Codes),
     (   Length > IfLonger
     ->  First is IfLonger - 5,
         Skip is Length - 5,
         skip_first(Skip, Codes, Rest),
         put_n_codes(First, Codes, C),
         format('...', [])
     ;   Rest = Codes
     ),
     put_var_codes(Rest, C),
     put_code(C).
The use of maplist/3 is elegant, and works since we do
not print open lists, right?

Hi,
 The most radical approach is Novacore from
Dogelog Player. It consists of the following
major incisions in the ISO core standard:
 - We do not forbid chars, like for example
   using lists of the form [a,b,c], we also
   provide char_code/2 predicate bidirectionally.
 - We do not provide and _chars built-in
   predicates also there is nothing _strings. The
   Prolog system is clever enough to not put
   every atom it sees in an atom table. There
   is only a predicate table.
 - Some host languages have garbage collection that
   deduplicates Strings. For example some Java
   versions have an options to do that. But we
   do not have any efforts to deduplicate atoms,
   which are simply plain strings.
 - Some languages have constant pools. For example
   the Java byte code format includes a constant
   pool in every class header. We do not do that
   during transpilation , but we could of course.
   But it begs the question, why only deduplicate
   strings and not other constant expressions as well?
 - We are totally happy that we have only codes,
   there are chances that the host languages use
   tagged pointers to represent them. So they
   are represented similar to the tagged pointers
   in SWI-Prolog which works for small integers.
 - But the tagged pointer argument is moot,
   since atom length=1 entities can be also
   represented as tagged pointers, and some
   programming languages do that. Dogelog Player
   would use such tagged pointers without
   poluting the atom table.
 - What else?
 Bye

Technically SWI-Prolog doesn't prefer codes.
Library `library(pure_input)` might prefer codes.
But this is again an issue of improving the
library by some non existent SWI-Prolog community.

The ISO core standard is silent about a flag
back_quotes, but has a lot of API requirements

requires atom_codes/2 and atom_chars/2.

Implementation wise there can be an issue,

there is now an explosion.

Not sure whether Trealla Prolog and Scryer
Prolog thought about this problem, that the
atom table gets quite large. Whereas codes don't
eat the atom table. Maybe they forbit predicates

But who writes these libraries? The SWI Prolog

instead floods the web with workaround tips?
The SWI Prolog community.

Cannot improve its own tooling, is not willing
to support code from else where that uses chars.

The paper contains not a single reference to autoencoders!
Still they show this example:

Fig. 1 ILP systems struggle with structured examples that

I guess ILP is 30 years behind the AI boom. An early autoencoder

Well ILP might have its merits, maybe we should not ask
for a marriage of LLM and Prolog, but Autoencoders and ILP.
