• Independent of the UI
• Back-end executable
• Executed by UI (for example by an action), Web services or other modules such as the Workflow and Scheduler

You can write your own custom commands and execute them on-demand or scheduled.

...

...

The advantage of using a catalog is that you can have identically named commands. You might want two activate commands – one for pages and another for assets. To call a command that resides in a catalog, use the catalog name followed by a hyphen, then the command name. For example, you would distinguish the two activate commands by calling one with workflow-activate and the other with default-activate.

Executing commands with actions

...

...

...

Use the Groovy console to execute command business logic manually, in ad hoc fashion. This is a quick way to test a custom command before you compile it as a Java class. Both of the two options below publish the page /travel/about/careers .

...

You can test it by making a small change on the careers page, executing the Groovy commands, and viewing the modified history page on the public instance. 

• Open the Groovy app.

• Issue the following commands in the console:

  • Option A - Calling the info.magnolia.commands.CommandsManager.executeCommand():

    Code Block
    java java
    map = new java.util.LinkedHashMap<String, String>() map.put("path", "/travel/about/careers") map.put("repository", "website") cm = info.magnolia.commands.CommandsManager.getInstance() cm.executeCommand('default','publish',map)

  • Option B - Passing a SimpleContextobject to the execute() method:

    Code Block
    java java
    cm = info.magnolia.commands.CommandsManager.getInstance() command = cm.getCommand('activate')

...

• • command.setRepository('website')

...

• • command.setPath('/travel/about/careers')

...

• • command.setRecursive(true) command.execute(

...

This example activates the page /travel/about/careers. You can test it by making a small change on the careers page, executing the Groovy commands, and viewing the modified history page on the public instance.

...

• • new info.magnolia.context.SimpleContext())

Executing a command as a Groovy script

...

...

public class MyCommand extends BaseRepositoryCommand {
  public boolean execute(Context context) {
    // Your command logic goes here.
  }
}

See the commands in the  info.magnolia.commands.impl  package for examples.
