ipython shortcut to reload modules

[bernhard.voigt@gmail.com]

Hey!

I'm using ipython as my python shell and often run scripts with the
magic command %run:

In [1]: %run script.py

If modules are loaded within the script these are not reloaded when I
rerun the script. Hence, when I changed some of the modules loaded, I
have to call

In [2]: reload(module1)
Out [2]: <module 'module1' from ....
In [3]: reload(module2)
Out [3]: <module 'module2' from ...
In [4]: %run script.py

Is there a shortshut to reload the modules automatically before
rerunning the script?

In case of names imported from modules into the shell environment I
have to reload and re-import in order to have the changes available:

In [5]: from module1 import *
In [6]: reload(module1)
In [7]: from module1 import *

Is there a shortcut to force a reload of loaded modules and re-
defining the names loaded with from....import. ..?

Thanks! Bernhard

No. But if you're including them in the script, they won't be reloaded
because they're already present in the namespace. If you do %reset
before your %run, it'll clear up the namespace, so your script's import
should work. Downside: its effectively the same as quitting out of
ipython, and restarting it. Other then that, I don't think you have much
choice.
Oh, if you use the %edit command to edit these files, it should reload
them when you're done editing.
