.. _library_redis:
redis
Redis client library. Supports GNU Prolog, XVM, SICStus Prolog, SWI-Prolog, and XSB. Support for Ciao Prolog and ECLiPSe is also included but requires fixes for issues in these systems.
For general information on Redis, including a list of the available commands, visit:
::
Open the `../../docs/library_index.html#redis <../../docs/library_index.html#redis>`__ link in a web browser.
To load this library, load the loader.lgt
file:
::
| ?- logtalk_load(redis(loader))
.
To test this library predicates, load the tester.lgt
file:
::
| ?- logtalk_load(redis(tester))
.
The tests assume a localhost Redis server running on the default port
(6379) if the REDIS_HOST
and REDIS_PORT
environment variables
are not defined. 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
.
This library is inspired by the Sean Charles GNU Prolog Redis client library.
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.
