Prompt and history

[6r1d]

If I understand correctly, ptpython is using a buffer to interact with user and FileHistory is just connected to the buffer itself.

So, for instance, how should I change autocompletion.py example to make it function as a prompt and have a history, which reacts to "up" and "down" buttons?

#614 has an answer.
Source explains a lot, too:

    @handle('enter', filter=focused)
    def _(event):
        " Run system command. "
        # ...
        self.system_buffer.reset(append_to_history=True)
        # ...
