Command Lifecycle

• Commands have three lifecycle methods that are invoked when running the command:
  • initialize() (optional)
    • This method is executed before the interact() and the execute() methods. Its main purpose is to initialize variables used in the rest of the command methods.
  • interact() (optional)
    • This method is executed after initialize() and before execute(). Its purpose is to check if some of the options/arguments are missing and interactively ask the user for those values. This is the last place where you can ask for missing required options/arguments. This method is called before validating the input. Note that it will not be called when the command is run without interaction (e.g. when passing the --no-interaction global option flag).
  • execute() (required)
    • This method is executed after interact() and initialize(). It contains the logic you want the command to execute and it must return an integer which will be used as the command exit status.
