Coercer

A library for converting data of one type into another type.

Installation

Add the following dependency to your project.clj file:

[coercer "0.2.0"]

Usage

Use the coerce multimethod to convert between types:

(use 'coercer.core)

(coerce "50" Integer)  ; => 50

Supported Types

Currently coerce supports the following types by default:

• java.lang.String
• java.lang.Integer
• java.lang.Long
• java.lang.Float
• java.lang.Double
• clojure.lang.Keyword
• clojure.lang.Symbol
• java.util.Date
• org.joda.time.DateTime

But new coercions can be added by extending the coerce multimethod.

More Examples

Basic types:

(coerce 1 String)      ; => "1"
(coerce "5.5" Double)  ; => 5.5
(coerce "foo" Keyword) ; => :foo
(coerce :abc String)   ; => "abc"

Dates and date-times:

(use '[clj-time.core :only (now)])
(import 'java.util.Date)

(coerce (now) String)       ; => "2012-04-17T20:53:55.552Z"
(coerce (now) Long)         ; => 1334696086921
(coerce 1334696086921 Date) ; => #<Date Tue Apr 17 21:54:46 BST 2012>
