propertea

simple property loading, coercing, and validating

An Example

propertea can be used to load a property file, convert, and validate. The following snippet shows loading a file and converting a few of the properties to their desired types.

;Given the following properties file
;string-example=hello-string
;int-example=1
;boolean-example=true

(ns example 
  (:use propertea.core))         

(def props (read-properties "test/fake.properties" 
                            :parse-int [:int-example] 
                            :parse-boolean [:boolean-example]))

(println props) 
; => {:int-example 1, :string-example "hello-string", :boolean-example true}

propertea can also validate that required properties are specified.

; assuming the same properties file as above

(ns example 
  (:use propertea.core))         

(def props (read-properties "test/fake.properties" :required [:req-prop])) 
; => java.lang.RuntimeException: (:req-prop) are required, but not found
