pip search に自分好みの表示機能を加える

こんにちは。
python のライブラリモジュールを（pypi 内で）検索するには下記のように pip コマンドを利用して検索結果を得ますが、加えて下記のような結果表示も加えたくなりました。

$ pip search cvxopt
cvxopt                    - Convex optimization package
  INSTALLED: 1.1.7 (latest)
  https://pypi.python.org/pypi/cvxopt   <== この表示を加えたい

$ pip search pandas
pandas                    - Powerful data structures for data analysis, time series,and statistics
  LATEST:    0.15.2 (not installed)     <== この表示を加えたい
  https://pypi.python.org/pypi/pandas   <== この表示を加えたい

そこで、pip (v.6.0.x) の search に少し手を加えて実現してみました。

$ ./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
