``redis``
=========

Redis client library. Supports GNU Prolog, LVM, Qu-Prolog, SICStus
Prolog, SWI-Prolog, and XSB. Support for ECLiPSe is also included but
requires a fix for an ECLiPSe bug that is expected in a forthcoming
version of this Prolog system.

Loading
-------

To load this library, load the ``loader.lgt`` file:

::

   | ?- logtalk_load(redis(loader)).

Testing
-------

To test this library predicates, load the ``tester.lgt`` file:

::

   | ?- logtalk_load(redis(tester)).

The tests assume a local Redis server running on the default port. If
the server is not detected, the tests are skipped.

The unit tests were originally written by Sean Charles for his GNU
Prolog Redis client library:

::

   https://github.com/emacstheviking/gnuprolog-redisclient

The Logtalk version is a straight-forward port of the original tests
using the ``test/1`` dialect of ``lgtunit``.

Credits
-------

This library is inspired by the Sean Charles GNU Prolog Redis client
library.

Known issues
------------

Recent version of macOS seem to disable the mapping of ``localhost`` to
``127.0.0.1``. This issue may prevent running this library unit tests
and the ``redis::connect/1`` from working. This can be fixed either by
editing the
``/etc/hosts file or by using in alternative the predicate``\ redis::connect/3\ ``with``'127.0.0.1'\`
as first argument.
