Extended Summary

Example

In [1]: l = ['hello',10,'world']
In [2]: %store l
Stored 'l' (list)
In [3]: exit

(IPython session is closed and started again...)

ville@badger:~$ ipython

Usage:

• %store - Show list of all variables and their current

  values

• %store spam bar - Store the current value of the variables spam

  and bar to disk

• %store -d spam - Remove the variable and its value from storage

• %store -z - Remove all variables from storage

• %store -r - Refresh all variables, aliases and directory history

  from store (overwrite current vals)

• %store -r spam bar - Refresh specified variables and aliases from store

  (delete current val)

• %store foo >a.txt - Store value of foo to new file a.txt

• %store foo >>a.txt - Append value of foo to file a.txt

It should be noted that if you change the value of a variable, you need to %store it again if you want to persist the new value.

Note also that the variables will need to be pickleable; most basic python types can be safely %store'd.

Also aliases can be %store'd across sessions. To remove an alias from the storage, use the %unalias magic.
