@schettino72 let me know if you have any feedback :)

• add new command line option --show-action (better name suggestions welcome)
• implement a title() method for PythonAction & CmdAction
• Reporter will also need a new method to be called before each action

keep going 😄

* [ ]  Reporter will also need a new method to be called before each action

I am confused about this. The reporter is not looping over actions. The for action in ... loop is inside task.py:Task.execute:

    def execute(self, stream):
        ...
        task_stdout, task_stderr = stream._get_out_err(self.verbosity)
        for action in self.actions:
            action_return = action.execute(task_stdout, task_stderr)
            ...

So we need to make Task.execute call the reporter for each action. Every output must be through a reporter.

So we need to make Task.execute call the reporter for each action. Every output must be through a reporter.

I am planning to add a reporter argument to the Task.execute function signature, so that Task.execute can access the reporter.

I was only able to support ConsoleReporter. I tried to support JsonReporter but there were lots of exceptions related to task_dispatcher that I was't able to debug.
