Gulash

The goal of this project is to create a small java/groovy dsl on top of mule esb. And that it should be very easy to contribute and extend.

Java Example

Mule mule = new Mule();
mule.declare( 
    flow("Test")
            .then(choice()
                        .on("#[payload.name == 'mariano']").then(log("mariano"))
                        .on("#[payload.name == 'martin']").then(log("Martin"))
                        .otherwise().then(log("otherwise"))
                ) 
); 
mule.start();

Groovy Example

declare(
        api("rover.raml")
                .on("/motion/forward" , ActionType.PUT)
                    .then(log("#[payload]"))
                .on("/motion/backard" , ActionType.PUT)
                    .then(log("#[payload]"))
                .on("/motion/left" , ActionType.PUT)
                    .then(log("#[payload]"))
                .on("/motion/right" , ActionType.PUT)
                    .then(log("#[payload]"))

);

Using a Cloud Connector

require "Twitter"


String consumerKey = "";
String consumerSecret = "";
String accessKey = "";
String accessSecret = "";


declare Twitter.config(consumerKey, consumerSecret)
                .accessKey(accessKey)
                .accessSecret(accessSecret).as("twitterConfig");


declare flow("main")
                .on(endpoint("http://localhost:8081"))
                .then(Twitter.updateStatus("#[payload]").using("twitterConfig"))
                .then(setPayload("Your twitter status updated!"))

Dependencies

The require instruction allows to dynamically fetch a module and add it to the execution

require "ModuleName" version "Version" from "url"

• If version is not specified the last one is going to be picked
• Url is only required if the module is in other repository different to central or local

Features

• Supports some mule core element
• Foreach/Choice/Flow/Exception Strategy
• Logger/Set Payload
• Poll
• Supports APIKit
• Basic Scaffolding from raml file.
• Devkit dsl generation from @Module and @Connectors
• Dependency support through require expression

Building & Installation

Just use maven

mvn clean install

And a distribution will be generated under goulash/target/goulash.zip

Just unzip it and you have it installed

Running a script

goulash/bin/goulash.sh example.groovy

usage: gulash.sh <File>
 -c <RAML file>                           Create a script based on the
                                          specified RAML file.
 -get <Dependency Module Name.>           Downloads the required
                                          dependency so it is available at
                                          runtime.
 -help                                    Print this message
 -i                                       Starts an interactive console
                                          for fast testing.
 -list <Dependency Module Version.>       The version of the dependency.
                                          If not specified use the latest
                                          one.
 -version <Dependency Module  Version.>   The version of the dependency.
                                          If not specified use the latest
                                          one.
