Pure I/O in Dogelog Player (Re: ANN: Dogelog Player 1.3.3 (Dark Mode))

Show all headers | View raw

Dogelog Player is a Prolog system mainly written
in Prolog itself. A library(pio) for Pure I/O is
not part of this Prolog systems. Herein we report
a successful experiment of implementing such a
library. The library has a Web 2.0 realization
since the streams can even originate from URLs.

Instead of going with memory mapping or attributed
variables, our main idea is to use ‘C’/3 to
detect Haskell lazy and realize it with change_arg/3.
The grammar backtracking is potentially unlimited.
There is a separation of concern into a get_lazy/3
and the unit need not be codes.
