Purity Quick Start

There are two versions of Purity, a standalone version that contains no module information and a package that can be installed using SWI-Prolog.

SWI-Prolog Package

1. Install the purity pack, following the instructions. ?- pack_install(purity).
2. Set the prolog flag to allow double quotes to become chars. ?- set_prolog_flag(double_quotes, chars).
3. Include the purity libraries in the code. ?- use_module(library(pstring)). ?- use_module(library(plist)).
4. Write a query ?- assert(( purity_test(S, R) :- pstr_split(S, ' ', Split), pexclude((eq(pstring, "is"), Split, Small), pstr_join(Small, '-', R) )). true.

   ?- purity_test("This is a test", R), maplist(write, R), nl. This-a-test R = ['T', h, i, s, -, a, -, t, e|...].

   Ready for action.
