redis-lua
-------------------------------------------------------------------------------
A Lua client library for the redis key value storage system.
== USAGE:
* Include redis-lua in your script:
require 'redis'
* Connect to a redis-server instance and send a PING command:
local redis = Redis.connect('127.0.0.1', 6379)
local response = redis:ping() -- true
* Set and get a key+value:
redis:set('usr:nrk', 10)
redis:set('usr:nobody', 5)
local value = redis:get('usr:nrk') -- 10
* Increment and decrement integer values:
redis:increment('usr:nrk') -- 11
redis:decrement_by('usr:nobody', 3) -- 2
* Return all the keys matching the specified pattern:
local keys = redis:keys('usr:*') -- {'usr:nrk','usr:nobody'}
* Sort list values by using various parameters supported by the server:
for _,v in ipairs({ 10,3,2,6,1,4,23 }) do
redis:push_tail('usr:nrk:ids',v)
end
local sorted = redis:sort('usr:nrk:ids', {
sort = 'asc', alpha = true, limit = { 1, 5 }
}) -- {1= 10, 2= 2 , 3= 23, 4= 3, 5= 4}
* Get infos from the server:
for k,v in pairs(redis:info()) do print(k .. ' => ' .. v) end

== TODO:
* improve methods such as connect and get_multiple
* redis-lua actually needs more error-checking code
* complete the test suite
* write more docs
== REQUIREMENTS:
* LuaSocket: http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/
* Telescope (required by the test suite): http://telescope.luaforge.net/
