Love this. Thanks.

I can see a bunch of ways I'll make use of this. The first one I attempted to work on involved trying to color scale the use% in the output of a "df -h".

Alas it didn't work as I expected it:

    $ df -h | colout --scale 0,100 "([0-9]*)%" scale
    ValueError: could not convert string to float:

However if I grep out just the /dev/sda line it does what I expected:

    $ df -h | grep /dev/sda | colout --scale 0,100 "([0-9]*)%" scale
    /dev/sda         20G  3.2G   16G  17% /

The 17% is a pretty blue.

Tips?

You use the "zero or more" * operator, which will match empty strings in front of the "%". But an empty string cannot be converted to a float. Just use the "at least one" operator: +. Also, the scale is 0,100 by default, you can omit it.

    df -h | colout "([0-9]+)%" scale

Thanks for the response. My lazy regex makes me feel bad.

Also, the install docs mention python2.7 but after a bit of head to brickwall I realised that this is trying to use python3.

To get it working I needed to do:

    sudo python3 setup.py install

And /usr/local/bin/colout was created for me (unlike what it mentions in the readme atm).
