colorize

========

\*nixy filter that adds color to its standard input by rows or columns

Example usage

* output alternate rows in different colors::

  $ ls -l | colorize.py -a

  $ ls -l | colorize.py -a green,blue

* output each space separated column from stdin in a different color::

  $ tail -f logfile | colorize.py

  $ tail -f logfile | colorize.py -c green,blue,red,yellow

* output the first 3 space separated columns in different colors and all subsequent text in one color::

  $ tail -f logfile | colorize.py 3

  $ tail -f logfile | colorize.py -c green,blue,red 3

* output the columns specified by widths in different colors

::

  # - The first 10 characters is green, the next 12 in red, followed by space

  # separated columns alternating in green and red

  $ tail -f logfile | colorize.py -c green:10,red:12

  # - The first 10 characters in green, the next 12 in red, all subsequent text in yellow

  $ tail -f logfile | colorize.py -c green:10,red:12,yellow 3

  # - The first 10 characters in the default first color (blue), the next 12 in green,

  # the next space separated column in red, the subsequent text in yellow

  $ tail -f logfile | colorize.py -c :10,green:12,red,yellow 4

* filter the output of tail -f, coloring lines from each file in different color::

  $ tail -f first.log second.log | colorize.py -t

  $ tail -f first.log second.log | colorize.py -t green,yellow

Usage Tip

=========

If you use `bash`, you can create colorized versions of commands, like::

    function ctail() { tail $@ | colorize.py -t; }

    function cll() { ls -l $@ | colorize.py 8; }

    function cvmstat() { vmstat $@ | colorize.py -a red,green; }
