    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?
  • 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
