cowsay is a configurable talking cow, originally written in Perl by Tony Monroe

This project is a translation in JavaScript of the original program and an attempt to bring the same silliness to node.js.

Install

npm install -g cowsay

Usage

cowsay JavaScript FTW!

or

cowthink node.js is cool

It acts in the same way as the original cowsay, so consult cowsay(1) or run cowsay -h

}
}

getting a list of cow names:
`ts
function get_cows(error: NodeJS.ErrnoException, cow_names: Array): void {
if (error) {
console.log(Error getting cow names: ${error.message})
}
else if (cow_names) {
console.log(Number of cows available: ${cow_names.length});
}
}

cowsay.list(get_cows);
`

importing the IOptions interface directly:
`ts
import { IOptions } from "cowsay" // optional

let opts: IOptions = {
text: "Hello from TypeScript!",
e: '^^',
r: true,
};

console.log(cowsay.say(opts));
`

Pipe from standard input

echo please repeat | cowsay

Usage in the browser

cowsay works in your browser too with rollup / webpack / browserify / you name it.

`js
import { say } from 'cowsay';

console.log(say({ text: 'grazing in the browser' }));
`

You can customize the cow by importing the relevant one

`js
import { think, SQUIRREL } from 'cowsay';

console.log(think({
text: 'grazing in the browser',
cow: SQUIRREL,
eyes: 'pp',
tongue: ';;',
}));
`

All cows are included in the bundle, but you can use rollup / webpack tree-shake feature to reduce the final bundle size.

$3

`js
say({
text: 'hello',
cow: '', // Template for a cow, get inspiration from ./cows
eyes: 'oo', // Select the appearance of the cow's eyes, equivalent to cowsay -e
tongue: 'L|', // The tongue is configurable similarly to the eyes through -T and tongue_string, equivalent to cowsay -T
wrap: false, // If it is specified, the given message will not be word-wrapped. equivalent to cowsay -n
wrapLength: 40, // Specifies roughly where the message should be wrapped. equivalent to cowsay -W
mode: 'b', // One of "b", "d", "g", "p", "s", "t", "w", "y"
});
