Clutch is a Clojure library for Apache CouchDB. Although it’s in an early stage of development (Clutch API subject to change), Clutch supports most of the basic Apache CouchDB APIs. To get a sense of where we are at with Clutch, please view the tests .
Clutch uses Leiningen. For installation and help on using Leiningen visit the github repo .
To include Clutch in your project, in your project.clj add the following to your “:dependencies”:
[com.ashafa/clutch "0.2.1"]
… then from your command line, execute:
lein deps
This will create a compiled Clutch jar in the “/lib” (or path indicated by your leiningen project.clj file) of your project.
If you are working with a clone of Clutch from github for development, contribution, or testing purposes, in your command line in the project directory, execute:
lein install
This will leave a fully-compiled Clutch jar file in the project directory.
You can also run the Clutch tests by executing the following in your command line:
lein test test-clutch
To use Clojure for views and filters, add the following to the ‘local.ini’ file of your CouchDB installation (replacing <path to…> with the appropiate paths).
[query_servers] clojure = java -cp <path to clojure.jar>/clojure.jar:<path to clojure-contrib.jar>/clojure-contrib.jar:clutch.jar com.ashafa.clutch.view_server
Clutch is currently being tested on Apache CouchDB version 0.10.1
