Sublime Text 3: Write text to output panel

Question

I am trying to create a Sublime Text 3 plugin which writes output to an output panel in the current window. I have found a number of examples doing this using begin_edit and end_edit, which are no longer supported in ST3. To my understanding, ST3 requires that I define a TextCommand to support the editing action on my output panel. So far, what I have is this:

class SfprintCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.insert(edit, self.view.size(), 'hello')

class SfCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self.panel = self.view.window().create_output_panel('sf_st3_output')
        self.view.window().run_command('show_panel', { 'panel': 'output.sf_st3_output' })
        self.panel.run_command('sfprint');

I would expect that this should print the text "hello" in my output panel, but when I try to invoke this through the console (by running view.run_command('sf')), this displays the new panel but does not print any information to it. How can I write text to this panel?

Justification

works for me... can you verify that self.view.id() in SfprintCommand's run method is the same as self.panel.id() in Sfcommand's run method? are there any errors in the Sublime console? – Quarter

After restarting everything, the same code seems to be working now. My lesson learned: apparently it's best not too put too much faith into ST3's hot plugin reloading!
