"""
Add copy to clipboard from IPython!
To install, just copy it to your profile/startup directory, typically:
~/.ipython/profile_default/startup/
Example usage:
%clip hello world
# will store "hello world"
a = [1, 2, 3]
%clip a
# will store "[1, 2, 3]"
You can also use it with cell magic
In [1]: %%clip
...: Even multi
...: lines
...: work!
...:
If you don't have a variable named 'clip' you can rely on automagic:
clip hey man
a = [1, 2, 3]
clip a
This is a fork of https://gist.github.com/nova77/clip_magic.py
which enables support for windows (using Tkinter) and adds linux
support for xclip (in additional to xsel) if available.
