Or install it yourself as:

Usage(function of Rails_Kvs_Driver.)

define driver configuration

“uby
driver_config = {
host => ‘localhost’, # host of redis
port => 6379, # port of redis
namespace => ‘Example’, # namespace of key
timeout_sec => 5, # timeout seconds
pool_size => 5, # connection pool size
config_key => :none # This key is option. (default=:none) # when set this key. # will refer to a connection-pool based on config_key, # even if driver setting is the same without this key. }

“

connect and exec basic (set/get/delete)

session method enables connection pool. “uby You can use Enumerable.

RailsKvsDriver::RedisDriver::Driver::session(driver_config) do |redis|

# set key to redis. redis[animation] = ‘good!’ redis[nyarukosan] = ‘kawaii!’

# get value from redis. puts redis[animation] # => ‘good!’

# exec each redis.each do |key,value| puts “#key is #value!” # => animation is good!! # => nyarukosan is kawaii!! end

# check existed. redis.has_key?(‘animation’) # => true

# get all keys. redis.keys # => [animation, nyarukosan]

# delete key from redis. redis.delete(‘nyarukosan’)

# delete all keys. redis.delete_all

end

“

list

“uby lists include Enumerable.

RailsKvsDriver::RedisDriver::Driver::session(driver_config) do |redis|

# set value to list. redis.lists[anime][0] = ‘nyarukosan’ redis.lists[anime][1] = ‘kinnmoza’ redis.lists[anime][2] = ‘outbreakcompany’

# or can use this. redis.lists[fruit] = [:apple, :orange]

# get value of list. puts redis.lists[anime][0] # => ‘nyarukosan’

# execute the block of code for each keys. redis.lists.each do {|key| puts key } # => anime fruit

# execute the block of code for each member of list. redis.lists[anime].each do |index, value| puts “#index: #value.” # => ‘0: nyarukosan.’ # => ‘1: kinnmoza.’ # => ‘2: outbreakcompany.’ end

# get all keys redis.lists.keys? # => [anime, fruit]

# length of sorted set. redis.lists.length # => 2

# length member of sorted set. redis.lists[anime].length # => 3

# delete key redis.lists.delete(‘fruit’)

# remove member of list. redis.lists[anime].delete(‘kinnmoza’)

# or can use this. redis.lists[anime].delete_at(1)

end

sorted set

“uby sorted_sets include Enumerable.

RailsKvsDriver::RedisDriver::Driver::session(driver_config) do |redis|

# set member to redis. redis.sorted_sets[anime]['nyarukosan'] = 10 redis.sorted_sets[anime]['nonnonbiyori'] = 5 redis.sorted_sets[anime]['kiniromosaic'] = 1

# or can use this. redis.sorted_set[fruit] = [[‘apple’, 1], [orange, 2]]

# get score of member. redis.sorted_sets[anime]['nyarukosan'] # => 10

# increment score of member. redis.sorted_sets[anime].increment(‘nyarukosan’, 1) # => increment nyarukosan score 10 -> 11 redis.sorted_sets[anime].increment(‘nyarukosan’, -1) # => increment nyarukosan score 11 -> 10

# execute the block of code for each keys. redis.sorted_sets.each do {|key| puts key } # => anime fruit

# execute the block of code for each member of sorted set. redis.sorted_sets[anime].each(true) do |member, score, position| puts “#position+1:#member is #scorept.” # => ‘1:nyarukosan is 10pt.’ # => ‘2:nonnonbiyori is 5pt.’ # => ‘3:kiniromosaic is 1pt.’ end

# get all keys redis.sorted_sets.keys? # => [anime, fruit]

# get all members redis.sorted_sets[anime].members? # => nyarukosan nonnonbiyori kiniromosaic

# length of sorted set. redis.sorted_sets.length # => 2

# length member of sorted set. redis.sorted_sets[anime].length # => 3

# delete key redis.sorted_sets.delete(‘fruit’)

# remove member of sorted set. redis.sorted_sets[anime].remove(‘nonnonbiyori’)

# check if key exist. redis.sorted_sets.has_key?(‘fruit’) # => false

# check if member exist. redis.sorted_sets[anime].has_member?(‘nyarukosan’) # => true
