This is an incomplete, experimental Ruby FFI interface to Hiredis.

It exists mainly as a tool to teach me about Ruby's FFI interface and, as such, the location of the libhiredis library is hard-coded into hiredis.rb as being /usr/local/lib. If you want to tinker with this yourself, make sure to amend that path as necessary.

Prerequisites

• Hiredis 0.9.2 installed to /usr/local/lib.

Usage

# With the project's lib directory on your load path...
require "helloredis"

redis = Helloredis.new # defaults to connecting to 127.0.0.1:6379
redis.set("foo", "bar")
# => "OK"
redis.get("foo")
# => "bar"
redis.lpush("mylist", "arnold")
# => 1
redis.lpush("mylist", "bob")
# => 2
redis.sort("mylist", :alpha => true, :order => :desc, :count => 1, :offset => 0)
# => ["bob"]

See spec/helloredis_spec.rb for more usage information.
