This could probably be fixed by overwriting eiter the input_prefilter() or pre_runcode_hook() as described on http://ipython.scipy.org/doc/stable/html/api/generated/IPython.hooks.html#IPython.hooks.shell_hook

#12719 also fixes this.

comment:3 Changed 9 years ago by jhpalmieri

After applying the patches at #12719, I see

sage: %bg factor(next_prime(10^30)*next_prime(10^40))
ERROR: Line magic function `%bg` not found.

So I guess it is "fixed" in one sense, but not very satisfactorily.

Ah, good point. In fact, I think %bg isn't implemented yet in IPython. It's on the list of things to do by IPython developers.
