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

        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.

### Browser options

```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"
});
```
