## spilling the beans
```clojure
$ make repl
=> (require '[redclaw.core :as rc] ;; core functionality
'[redclaw.data :as rd]) ;; working with data/structures
=> (def redis (rc/connect)) ;; by default will connect to a locally running redis on 6379 port
#'user/redis
```
```clojure
;; a map
=> (def solar-system (rc/rmap redis "solar-system"))
#'user/solar-system
=> (rd/into solar-system {:saturn {:age 4503000000} :jupiter {:age 4603000000}})
=> solar-system
{:jupiter {:age 4603000000}, :saturn {:age 4503000000}}
=> (:jupiter solar-system)
{:age 4603000000}
```
clojure seq functions, such as `into`, for maps, sets, lists, etc.. would work the same way they do on clojure seqs taking vectors and all:
```clojure
;; a set
=> (def planets (rc/rset redis "planets"))
#'user/planets
=> (rd/into planets [:mercury :venus :earth :mars :jupiter :saturn :uranus :neptune])
=> planets
#{:uranus :jupiter :saturn :mercury :neptune :venus :mars :earth}
user=> (rd/conj planets :pluto)
true
;; now with pluto
user=> planets
#{:uranus :jupiter :saturn :mercury :neptune :pluto :venus :mars :earth}
;; "some" clojure fns
user=> (some #{:proxima-centauri-b} planets)
nil
user=> (some #{:proxima-centauri-b :saturn} planets)
:saturn
```
atomic long
```clojure
user=> (def stars (rc/rlong redis "number-of-stars"))
user=> stars
#object[org.redisson.RedissonAtomicLong 0x426913c4 "0"]
user=> (repeatedly 42 #(rd/incr counter))
user=> (rd/get stars)
42
```
> _`redclaw.data` also has one to one redisson mapped functions: `add`, `add-all`, `get-all`, etc.._
looking inside the source (redis server):
```bash
127.0.0.1:6379> keys *
1) "planets"
2) "solar-system"
3) "number-of-stars"
redis 127.0.0.1:6379> smembers "planets"
1) "\x04>\x05earth"
2) "\x04>\x05pluto"
3) "\x04>\ajupiter"
4) "\x04>\x06saturn"
5) "\x04>\x06uranus"
6) "\x04>\aneptune"
7) "\x04>\amercury"
8) "\x04>\x04mars"
9) "\x04>\x05venus"
redis 127.0.0.1:6379> get "number-of-stars"
"42"
```
