Adrián Arroyo Calle f2940ddfcf Some minor fixes. Thanks to @triska for them! 2022-10-26 23:36:07 -06:00
Markus Triska b2cccab768 ENHANCED: library(crypto): Faster conversion to bytes when the integer is known. 
These entailed constraints only affect performance, and can be removed
without affecting the correctness of the code. They speed up scalar
multiplication of a curve point, used for example in Bitcoinolog.

Markus Triska a891cc4edf use (slightly) better variable names 2022-10-26 23:36:07 -06:00
Markus Triska 706ab2ae5b use newly available must_be(chars, ...) for better and shorter type test 2022-10-26 23:36:07 -06:00
Markus Triska 9c1de8e00b ENHANCED: Eliminate the OpenSSL dependency of library(crypto). 
This is achieved by using the newly available crrl crate by @pornin
to implement crypto_curve_scalar_mult/4 for secp256k1. Many thanks!

Markus Triska ce313b8a6b correct nth0/4 and nth1/4 
As per https://github.com/triska/scryer-prolog/commit/56b430ecaf9bd59fb7bd0b1e56d451ab322c422e#commitcomment-82155379.

Markus Triska 7c96b91663 remove nth1/3, which is now provided by library(lists) 2022-10-26 23:36:07 -06:00
Markus Triska 87e966e185 remove nth1/3, which is now provided by library(lists) 2022-10-26 23:36:07 -06:00
Markus Triska 1e018681de ENHANCED: Much improved nth0/3, taken from #1529. 
This also adds nth0/4 and bootstraps nth1/[3,4] from it.
 2022-10-26 23:36:07 -06:00
Markus Triska 5b324680ba ADDED: must_be/can_be(not_less_than_zero, ...) 
See #1309.

Markus Triska abca5fc405 better implementation of list_si/1 
Per discussion in https://github.com/mthom/scryer-prolog/pull/1589.
 2022-10-26 23:36:07 -06:00
Markus Triska 6a455d2866 ADDED: chars_si/1, testing for a string 
Examples:

    ?- chars_si("hello").
       true.

    ?- chars_si(5).
       false.

    ?- chars_si([a,b,c|Rs]).
       error(instantiation_error,sort/2).

Markus Triska 5ec837acb4 ADDED: octet_character and octet_chars, testing for strings that represent bytes. 2022-10-26 23:36:07 -06:00
Markus Triska 76e33d051c rely on the built-in DCG expansion, per discussion in #1577 2022-10-26 23:36:07 -06:00
Markus Triska 7c5318b784 ENHANCED: Use '$skip_max_list'/4 for greater efficiency of nth0/3. 
This is now possible due to 4c7e2eb8614da9c04f2286f6116b468017fb442c.

See #1529 for the suggestion by @UWN.
 2022-10-26 23:36:07 -06:00
Markus Triska 47892bf24a ENHANCED: Improve determinism of ... //0 and seq//1. 
Example:

    ?- phrase(..., "hello").
       true.

This addresses #1577.

Mark Thom 91d4e91f53 prefix inlined goals with module names in expand_subgoal/5 (#1551) 2022-10-26 23:36:07 -06:00
Markus Triska c7caf6b7a9 ENHANCED: CLP(ℤ): Reduce redundant propagator invocations during all_distinct/1 filtering 
First, the current propagator is now logged and not re-triggered
during filtering. Second, and more significantly, all neq_num/2
constraints are scheduled and processed before more global constraints
are invoked. In this way, all the distilled information can be taken
into account by subsequently invoked global constraints.

These changes yield a 3-fold improvement in several Sudoku instances,
and a significant runtime reduction in social golfer instance 8-4-9.

Markus Triska 15cc916333 FIXED: can_be(chars, [a,X]), i.e., if variables occur as elements

other cases like it.
