Python Cowsay

A rewrite of cowsay in python. Allows for parsing of existing .cow files.

Install

pip install python-cowsay

Usage

The classic cowsay can be generated by the cowsay or cowthink functions:

from cowsay import cowsay

message = """
The most remarkable thing about my mother is that for thirty years she served
the family nothing but leftovers.  The original meal has never been found.
		-- Calvin Trillin
""".strip()
print(cowsay(message))

Will yield:

 __________________________________________ 
/ The most remarkable thing about my       \
| mother is that for thirty years she      |
| served the family nothing but leftovers. |
| The original meal has never been found.  |
|                                          |
\ -- Calvin Trillin                        /
 ------------------------------------------ 
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

The parameters for these functions are:

message – a string to wrap in the text bubble
cow='default' – the name of the cow (valid names from list_cows)
preset=None – the original cowsay presets: -bggpstwy
eyes=Option.eyes – A custom eye string
tongue=Option.tongue – A custom tongue string
width=40 – The width of the text bubble
wrap_text=True – Whether text should be wrapped in the bubble
cowfile=None – A custom string representing a cow

Other Functions

The available builtin cows can be found with list_cows. A cow can be chosen
randomly from this list with get_random_cow.

Using Your Own Cows

A custom .cow file can be parsed using the read_dot_cow function which takes
a TextIO stream. I.e., You can either create a TextIO from a string or read
a file.

The read_dot_cow will look for the first heredoc in the steam and extract the
heredoc contents. If no heredoc exists, the whole stream is used instead. Escape
characters are then escaped. The default escape characters can be changed by
passing in an optional escape dictionary parameter mapping escape codes to
their chars.

For example:

from io import StringIO

from cowsay import read_dot_cow, cowthink

cow = read_dot_cow(StringIO("""
$the_cow = <<EOC;
         $thoughts
          $thoughts
           ___
          (o o)
         (  V  )
        /--m-m-
EOC
"""))
message = """
Nothing is illegal if one hundred businessmen decide to do it.
        -- Andrew Young
""".strip()
print(cowthink(message, cowfile=cow))

Will yield:

( businessmen decide to do it.      )
(                                   )
( -- Andrew Young                   )
