TL;DR

Being silly with cowsay.

Do you know cowsay?

$ cowsay 'Hello, world!'
 _______________
< Hello, world! >
 ---------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

Too cute! I thought to make a little wrapper to produce cow-ments for code instead, so here’s cowment:

Local version here.

Use it by passing the comment you want to spice up:

$ cowment 'This section is really important, watch out!'
type: 'elephant-in-snake'

Then copy, paste… and you’re done! The theme is chosen randomly among the available ones in the specific installation, although you can force one by setting environment variable TYPE:

$ TYPE=milk cowment 'This section is really important, watch out!'
type: 'milk'

It should not be too hard to adapt it to suit your programming language… this is left as a trivial exercise for the reader 🙄

Happy cow-menting!
