%alias_magic

[bfroehle]

A magic function which creates additional magic aliases.

• %alias_magic myedit edit: %myedit is an alias of %edit.
• %alias_magic mybash bash: %%mybash is an alias of %bash.
• %alias_magic mytimeit timeit: %mytimeit is an alias of %timeit, and %%mytimeit is an alias of %%timeit.
• %alias_magic --cell mytimeit timeit: Only %%mytimeit is an alias of %timeit.

Closes #641.

Code looks clean on first pass, but it's missing tests. There should be at least a test calling it to make an alias and then validate that the aliased function is found and is the correct one. Exercising the flags in separate tests would also be a good idea.

Thanks for this, though! I hope we can wrap it up in time for 0.13.

Okay, added a few tests.

Having a couple of one-line examples here would be useful. Just paste them from an interactive session.

In general, for magics we try to give examples so that people can see immediately how to use the tool, without having to figure it out from the documentation.

Thanks! I only noticed the need for a bit of example material (sorry I missed that on my first pass, I was about to merge and saw it now).

Once that goes in (should only take a minute), I'll be happy to merge, the implementation is perfect. Great job!

Tagged for 0.13, as this is basically ready.

Added note above that this closes $641.

I added a few %alias_magic examples:

  In [1]: %alias_magic t timeit

  In [2]: %t -n1 pass
  1 loops, best of 3: 954 ns per loop

  In [3]: %%t -n1
     ...: pass
     ...:
  1 loops, best of 3: 954 ns per loop

  In [4]: %alias_magic --cell whereami pwd
  UsageError: Cell magic function `%%pwd` not found.
  In [5]: %alias_magic --line whereami pwd

  In [6]: %whereami
  Out[6]: u'/home/testuser'

Sweet, thanks! Merging now.
