Markus Triska 19acd608a5 ADDED: library(http/http_open), opening HTTP and HTTPS streams for reading 
Example:

   ?- http_open("https://github.com/mthom/scryer-prolog", Stream, []),
      length(Ls, 10),
      maplist(get_char(Stream), Ls).

Yielding:

   %@    Stream = '$stream'(0x7fba4c59ef10), Ls = "\n\n\n\n\n<!DOC"
   %@ ;  false.

Markus Triska 8958ea036e ENHANCED: much faster format/3 for text streams 
This is now also used by format/2 to emit output on the terminal,
and significantly speeds up toplevel output of long strings.

Mark Thom d3563c30e7 Merge pull request #590 from triska/read_line_to_chars

Markus Triska 10a0f708b9 use format/3 to benefit from efficiency improvements 2020-06-14 10:51:24 +02:00
Markus Triska 409d3c168d ENHANCED: faster format/3 when writing to binary streams 
This is also more secure, since it does not change the atom table
and therefore leaves little trace of what was processed.

Markus Triska 40c3e31955 ENHANCED: phrase_from_file/[2,3] now read the file lazily. 
This allows processing extremely large files. In addition, the
efficient string representation helps to reduce memory usage.

These features unleash the full power of Prolog for text processing,
the exact use case Prolog was designed for.
