Interactive Prompt Enhancement

Some issues known or enhancement to add while implementing reloading script feature (#60). These will be fixed in the later update. Or we probably can ignore it when we have done supporting Jupyter Notebook access.

Known Issues

• If one rank failed and the other ranks are calling collective functions, then this leads to a deadlock.
  • Python coroutine (?)
  • Each rank create another thread to handle failure from other ranks.

Enhancement

• Colorful python prompt terminal
• Smart indent
• Able to change previous lines inputs or use arrow keys to move between characters.
  • ncurses
  • Erase the current printed console line and To input up arrow key
  • Can't deal with input keys like Crtl + D
• Drop unused keys in builtin. (ex: exit())
• Make result from directly input in prompt print in order.
• Assigning a functor directly to a variable through interactive prompt cannot be detected by libyt, since it create an empty space for code to run and detect. (Not sure do I really need this)
  • (This can't be detect) Ex: f = np.random.rand
  • (This can be detect)

    def f():
        return np.random.rand
    

• Cannot use different triple quotes when inputting function arguments in yt_run_FunctionArguments or %libyt run func args
  • Not really sure if this really is an issue, but I still put it here for reference.
  • Bug: Cannot Use " When Calling Python Function using API #72
