  Interview with Jonathan Slenders

• Introductions
• How were you first introduced to Python? -Chris
• What inspired you to create the python-prompt-toolkit?
• What are some design considerations that you made when building prompt-toolkit?
  • Make minimal use of inheritance
    • Overly strong coupling
    • Better clarity for the API of your library
    • Completely event driven / asynchronous
    • No global state

  
  
  • ptpython completion benefits from asynchrony – The jedi completion library is too slow – completion happens in its own thread
  
  
  
  


• You have built a number of projects that use the prompt-toolkit as a core component, did you have them in mind from the beginning, or are they experiments to test the capabilities of the toolkit?
  • tmux rewrite in Python, abandoned, original motivation for prompt-toolkit
  • ptpython
  • pgcli
  • ptpdb
  • pyvim



• Do you intend to bring PyVim to feature parity with Vim, or is it just intended for experimentation?
  • Short answer: Don’t know – but will probably never be in full parity with Vim



• What inspired you to create ptpython and why did you choose to make it a stand-along project rather than extending iPython?


• How difficult was it to integrate with IPython and what were the benefits?
  • IPython has its own event loop – this presented difficulties as prompt-toolkit has its own as well



• What are some of the most interesting uses that you have seen of the prompt-toolkit?
  • PyVim – really challenged the design
  • pgcli
