This issue will track all the different steps to bootstrap a new Python REPL with many new features. The target of this issue is that we can reach a point where new contributions can be made easily to the REPL once is written in pure Python. This issue only coveres the initial ground work to reach this status.

Tasks to be done:

• Redirect the parser and the main module to a new Python module.
• Fallback to the previous tokenizer-based REPL if the terminal is not a tty (and for backwards compat reasons)
• Bootstrap a new REPL module (based on a trimmed version pypy's pyrepl module).
• Ensure that the basic features work:
  • History
  • Completions
  • Ctrl-r and Ctrl-s

   I have a initial version that we can start building upon, I will create a PR shortly.

   I learned about this from the "core.py" podcast and it sounds like a great idea! I'd be happy help with this effort :)

   Fallback to the previous tokenizer-based REPL if the terminal is not a tty (and for backwards compat reasons)

   Do you mean not using _pyrepl? Can _pyrepl be used without readline nor tty?

   It needs at least a tty yes. Readline can be lifted but I am not sure yet

   I would like to see a new REPL (read, evaluate, print, loop) for the Python interpreter if the interpreter goes by a different name. Two other major Python interpreters also exist, and they already use other names ("bpython" and "ipython"). I would recommend forking the current REPL and renaming the interpreter with the new REPL to "zpython" instead. Also, I would like to see a built-in "clear()" function in the REPL as I already encounter with the "exit()" function and other REPL-specific functions.

    I think we can close this and handle the rest of the bugs in individual issues. Feel free to re-open if you feel otherwise.

    I absolutely love this change! I was using 3.12 and was thinking about making the change myself when I found this. Thank you all for your dedication!
