6.5 Creating Profile Commands 6.0.0

(Quick Reference) # 6.5 Creating Profile Commands Version: 6.0.0 ## 6.5 Creating Profile Commands A profile can define new commands that apply only to that profile using YAML or Groovy scripts. Below is an example of the create-controller command defined in YAML:
    description:
        - Creates a controller
        - usage: 'create-controller <<controller name>>'
        - completer: org.grails.cli.interactive.completers.DomainClassCompleter
        - argument: "Controller Name"
          description: "The name of the controller"
    steps:
     - command: render
       template: templates/artifacts/Controller.groovy
       destination: grails-app/controllers/`artifact.package.path`/`artifact.name`Controller.groovy
     - command: render
       template: templates/testing/Controller.groovy
       destination: src/test/groovy/`artifact.package.path`/`artifact.name`ControllerSpec.groovy
     - command: mkdir
       location: grails-app/views/`artifact.propertyName`
Commands defined in YAML must define one or many steps. Each step is a command in itself. The available step types are: `render` - To render a template to a given destination (as seen in the previous example) `mkdir` - To make a directory specified by the `location` parameter `execute` - To execute a command specified by the `class` parameter. Must be a class that implements the Command interface. `gradle` - To execute one or many Gradle tasks specified by the `tasks` parameter. For example to invoke a Gradle task, you can define the following YAML:
    description: Creates a WAR file for deployment to a container (like Tomcat)
    minArguments: 0
    usage: |
     war
    steps:
     - command: gradle
       tasks:
         - war
If you need more flexibility than what the declarative YAML approach provides you can create Groovy script commands. Each Command script is extends from the GroovyScriptCommand class and hence has all of the methods of that class available to it. The following is an example of the create-script command written in Groovy:
    description( "Creates a Grails script" ) {
      usage "grails create-script <<SCRIPT NAME>>"
      argument name:'Script Name', description:"The name of the script to create"
      flag name:'force', description:"Whether to overwrite existing files"
    }

    def scriptName = args[0]
    def model = model(scriptName)
    def overwrite = flag('force') ? true : false

    render  template: template('artifacts/Script.groovy'),
            destination: file("src/main/scripts/${model.lowerCaseName}.groovy"),
            model: model,
            overwrite: overwrite
