In Python, it is possible to overwrite any method of any object if you really want to. But IPython exposes a few 'hooks', methods which are designed to be overwritten by users for customization purposes. This module defines the default versions of all such hooks, which get used by IPython if not overridden by the user.
Hooks are simple functions, but they should be declared with self
as their first argument, because when activated they are registered into IPython as instance methods. The self argument will be the IPython running instance itself, so hooks have full access to the entire IPython object.
If you wish to define a new hook and activate it, you can make an extension
</config/extensions/index>
or a startup script <startup_files>
. For example, you could use a startup file like this:
import os
def calljed(self,filename, linenum):
"My editor hook calls the jed editor directly."
print "Calling my own editor, jed ..."
if os.system('jed +%d %s' % (linenum,filename)) != 0:
raise TryNext()
def load_ipython_extension(ip):
ip.set_hook('editor', calljed)

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
