Let's say you have a notebook something like this::
|
||
|
|
|
||
|
|
In [1]:
|
||
|
|
def func():
|
||
|
|
pass
|
||
|
|
|
||
|
|
In [2]:
|
||
|
|
something[]
|
||
|
|
|
||
|
|
Here, ``[]`` is the cursor position. When you hit the tab here,
|
||
|
|
you don't expect it to indent. However, python.el tries to follow
|
||
|
|
the indent of ``func()`` then you get indentation. This advice
|
||
|
|
workaround this problem.
|
||
|
|
|
||
|
|
Note that this workaround does not work with the MuMaMo based
|
||
|
|
notebook mode."
