Add your favorite display function to pip search

Hello. To search for a python library module (within pypi), use the pip command as shown below to get the search results, but I also wanted to add the following result display.

$ pip search cvxopt
cvxopt                    - Convex optimization package
  INSTALLED: 1.1.7 (latest)
  https://pypi.python.org/pypi/cvxopt   <==I want to add this display

$ pip search pandas
pandas                    - Powerful data structures for data analysis, time series,and statistics
  LATEST:    0.15.2 (not installed)     <==I want to add this display
  https://pypi.python.org/pypi/pandas   <==I want to add this display

So, I modified the search of pip (v.6.0.x) a little and realized it.

$ ./mypatch.rb search.py.patch

mypatch.rb

#!/usr/bin/ruby
# coding: utf-8
cmd = "patch -b -p0 < "
ARGV.each {|file|
    `#{cmd + file + " 2>&1"}`  # for sh/bash
}

search.py.patch
