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 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.

Credits

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

Known issues

Recent versions 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 predicate from working. This can be fixed either by editing the /etc/hosts file or by using in alternative the predicateredis::connect/3with’127.0.0.1’` as first argument.
