Modular Groovy Scripting

First we create an abstract class like this:

       
package test

public abstract class IncludeScript extends Script {
    def includeScript(scriptClass) {
        GroovyClassLoader gcl = new GroovyClassLoader();
        Class clazz = gcl.parseClass(new File(scriptClass));
        def scriptInstance = clazz.newInstance()
        scriptInstance.metaClass = this.metaClass
        scriptInstance.binding = new ConfigBinding(this.getBinding().callable)
        scriptInstance.&run.call()
    }
}
       
 

Compile the IncludeScript.groovy with groovyc and add the class-file to your classpath. Second we create something to test on like:

       


service{
 endpoint ="http://mysite.se/Service"
 port=4322
 user="admin"
 password="YmlsbDR5b3U="
}

//----------------------------------------------------------------------------------------
//Copy the code above to a file and name it to ServiceConfig.groovy
//----------------------------------------------------------------------------------------

import test.IncludeScript

class SecurityConfig extends IncludeScript {         
    def run() { // normal contents of a config file go in here
        
        security {
            includeScript( "c:\\tmp\\ServiceConfig.groovy" )
            active = true
        }

    }
 
}
//----------------------------------------------------------------------------------------
//Copy the code above to a file and name it to what you want, I named my to prop.groovy
//----------------------------------------------------------------------------------------

       
 

Now we test our modularity...

       

def conf = new ConfigSlurper().parse( new File("c:\\tmp\\prop.groovy").toURL() )
println conf.security.service.password
println conf.security.active
