''' 'Generic' functions for extending IPython.

Here is an example from genutils.py:
|
|
|
|
|
|
def print_lsstring(arg):
|
|
|
"Prettier (non-repr-like) and more informative printer for LSString"
|
|
|
print "LSString (.p, .n, .l, .s available). Value:"
|
|
|
print arg
|
|
|
|
|
|
print_lsstring = result_display.when_type(LSString)(print_lsstring)
|
|
|
|
|
|
(Yes, the nasty syntax is for python 2.3 compatibility. Your own extensions
|
|
|
can use the niftier decorator syntax introduced in Python 2.4).
