Use IPython from PyPy3

After installing PyPy3, use IPython with PyPy3 as the kernel by:

  1. install IPython in PyPy3:
   pypy3 -m pip install ipython
   
  1. create a file on your PATH, perhaps under ~/.local/bin/pypy3-ipython:
   #!/usr/bin/env pypy3
   import re
   import sys

   from IPython import start_ipython

   if __name__ == '__main__':
       sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
       sys.exit(start_ipython())
   

Now you should be able to type in Terminal

pypy3-ipython

to use IPython with the PyPy3 kernel.
