# `redis`

Redis client library. Supports GNU Prolog, 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.

## API documentation

Open the ../../docs/library_index.html#redis link in a web browser.

## 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.
