# redis-clojure | ||
|
||
A Clojure client library for the | ||
[Redis](http://code.google.com/p/redis) key value storage system. | ||
|
||
## Dependencies | ||
|
||
To use redis-clojure, you'll need: | ||
|
||
* The [Clojure](http://clojure.org) programming language | ||
* The [Clojure-Contrib](http://code.google.com/p/clojure-contrib) library (for running the tests) | ||
|
||
## Building | ||
|
||
To build redis-clojure: | ||
|
||
ant -Dclojure.jar=/path/to/clojure.jar | ||
|
||
This will build `redis-clojure.jar`. | ||
|
||
## Running tests | ||
|
||
To run tests: | ||
|
||
ant -Dclojure.jar=/path/to/clojure.jar -Dclojure-contrib.jar=/path/to/clojure-contrib.jar test | ||
|
||
*Note* you need to have `redis-server` running first. | ||
|
||
## Using | ||
|
||
To use redis-clojure in your application, simply make sure either | ||
`redis-clojure.jar` or the contents of the `src/` directory is on your | ||
classpath. | ||
|
||
This can be accomplished like so: | ||
|
||
(add-classpath "file:///path/to/redis-clojure.jar") | ||
|
||
## Examples | ||
|
||
Check the `examples/` directory. | ||
|
||
*Note* you need to have `redis-server` running first. | ||
|
||
## Todo | ||
|
||
* Work on performance | ||
* Maybe implement pipelining | ||
