Markus Triska f668640e3d move error handling to Prolog by using the new '$first_non_octet'/2 2021-11-04 18:35:22 +01:00
Markus Triska afcd44deaa ENHANCED: open/4 to allow opening a stream by specifying stream(S). 
This allows switching standard output to binary, using for example:

  ?- current_output(S0), open(stream(S0), write, S, [type(binary)]).

format/3 can then be used to write binary data to S. This is needed
for example when piping binary data to other programs.

This addresses #614, please read the discussion for more information.

The current implementation is very preliminary: Specifically, it works
by destructively modifiying the parameters of the underlying stream,
making it no longer usable in its original mode. Currently, if the
type of standard output is set to binary, then the toplevel no longer
works. Therefore, after writing binary output to standard output,
the program should either halt, or set the stream type back to text.

Markus Triska 55dabbe16a use '$first_non_octet'/2 for much faster domain check 2021-11-04 00:12:08 +01:00
Markus Triska 494bd7b79c ADDED: '$first_non_octet'/2, for much more efficient domain checks in library(crypto). 
'$first_non_octet'(Cs, C) <=> C is the leftmost character in the
string Cs whose character code is not in 0..255.
