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

Redis client. Inspired by Sean Charles GNU Prolog Redis client.

| **Availability:** 
|    ``logtalk_load(redis(loader))``

| **Author:** Paulo Moura
| **Version:** 0:5:1
| **Date:** 2021-12-06

| **Compilation flags:**
|    ``static, context_switching_calls``


| **Provides:**
|    :ref:`logtalk::message_tokens//2 <logtalk/0::message_tokens//2>`
| **Uses:**
|    :ref:`list <list/0>`
|    :ref:`logtalk <logtalk/0>`

| **Remarks:**

   - Command representation: Use the Redis command name as the functor of a compound term where the arguments are the command arguments.
   - Valid arguments: Atoms, integers, and floats. Always use atoms instead of double-quoted "strings". This helps portability by not depending on the value of the ``double_quotes`` flag.

| **Inherited public predicates:**
|    (none)
