This works with the standard python REPL, when calling ptpython by itself but not when we use ptpython.replembed() in our scripts.

from ptpython.repl import embed
embed(globals(), locals())

Then in the REPL:

>>> y=True                                                                                                                                                     

>>> [y for x in 'abc']                                                                                                                                         
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 1, in <listcomp>
NameError: name 'y' is not defined

name 'y' is not defined

From the normal ptpython or the standard REPL:

$ ptpython
>>> y=True                                                                                                                                                     

>>> [y for x in 'abc']                                                                                                                                         
[True, True, True]

test-driver: Run ptpython REPL at global scope
37ebe76 
This is a workaround for
prompt-toolkit/ptpython#279, which was making
it impossible to run the installer test interactively:

>>> start_all()
…
>>> test_script()
…
machine # [  382.137683] reboot: Power down
(7.06 seconds)
(8.23 seconds)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/nix/store/lbn2xnibdcvpgkpbrkdh2vlf1ap6930v-nixos-test-driver/bin/.nixos-test-driver-wrapped", line 888, in test_script
    exec(os.environ["testScript"])
  File "<string>", line 69, in <module>
  File "<string>", line 18, in create_machine_named
NameError: name 'default_flags' is not defined

name 'default_flags' is not defined

There’s no reason to expose the local variables of the run_tests
function, anyway.
