> Generate randomized strings of a specified length using simple character sequences. The original generate-password.

Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ npm install --save randomatic
```

## Usage

```js
var randomize = require('randomatic');
```

## API

```js
randomize(pattern, length, options);
randomize.isCrypto;
```

* `pattern` **{String}**: (required) The pattern to use for randomizing
* `length` **{Number}**: (optional) The length of the string to generate
* `options` **{Object}**: (optional) See available [options](#options)
* `randomize.isCrypto` will be `true` when a cryptographically secure function is being used to generate random numbers. The value will be `false` when the function in use is `Math.random`.

### pattern

> The pattern to use for randomizing

Patterns can contain any combination of the below characters, specified in any order.

**Example:**

To generate a 10-character randomized string using all available characters:

```js
randomize('*', 10);
//=> 'x2_^-5_T[$'

randomize('Aa0!', 10);
//=> 'LV3u~BSGhw'
```

* `a`: Lowercase alpha characters (`abcdefghijklmnopqrstuvwxyz'`)
* `A`: Uppercase alpha characters (`ABCDEFGHIJKLMNOPQRSTUVWXYZ'`)
* `0`: Numeric characters (`0123456789'`)
* `!`: Special characters (`~!@#$%^&()_+-={}[];\',.`)
* `*`: All characters (all of the above combined)
* `?`: Custom characters (pass a string of custom characters to the options)

### length

> The length of the string to generate

**Examples:**

* `randomize('A', 5)` will generate a 5-character, uppercase, alphabetical, randomized string, e.g. `KDJWJ`.
* `randomize('0', 2)` will generate a 2-digit random number
* `randomize('0', 3)` will generate a 3-digit random number
* `randomize('0', 12)` will generate a 12-digit random number
* `randomize('A0', 16)` will generate a 16-character, alpha-numeric randomized string

If `length` is left undefined, the length of the pattern in the first parameter will be used. For example:

* `randomize('00')` will generate a 2-digit random number
* `randomize('000')` will generate a 3-digit random number
* `randomize('0000')` will generate a 4-digit random number...
* `randomize('AAAAA')` will generate a 5-character, uppercase alphabetical random string...

These are just examples, [see the tests](./test.js) for more use cases and examples.

## options

> These are options that can be passed as the third argument.

#### chars

Type: `String`

Default: `undefined`

Define a custom string to be randomized.

**Example:**

* `randomize('?', 20, {chars: 'jonschlinkert'})` will generate a 20-character randomized string from the letters contained in `jonschlinkert`.
* `randomize('?', {chars: 'jonschlinkert'})` will generate a 13-character randomized string from the letters contained in `jonschlinkert`.

#### exclude

Type: `String|Array`

Default: `undefined`

Specify a string or array of characters can are excluded from the possible characters used to generate the randomized string.

**Example:**

* `randomize('*', 20, { exclude: '0oOiIlL1' })` will generate a 20-character randomized string using all of possible characters except for `0oOiIlL1`.

## Usage Examples

* `randomize('A', 4)` (_whitespace insenstive_) would result in randomized 4-digit uppercase letters, like, `ZAKH`, `UJSL`... etc.
* `randomize('AAAA')` is equivelant to `randomize('A', 4)`
* `randomize('AAA0')` and `randomize('AA00')` and `randomize('A0A0')` are equivelant to `randomize('A0', 4)`
* `randomize('aa')`: results in double-digit, randomized, lower-case letters (`abcdefghijklmnopqrstuvwxyz`)
* `randomize('AAA')`: results in triple-digit, randomized, upper-case letters (`ABCDEFGHIJKLMNOPQRSTUVWXYZ`)
* `randomize('0', 6)`: results in six-digit, randomized numbers (`0123456789`)
* `randomize('!', 5)`: results in single-digit randomized, _valid_ non-letter characters (`~!@#$%^&()_+-={}[]
* `randomize('A!a0', 9)`: results in nine-digit, randomized characters (any of the above)

_The order in which the characters are defined is insignificant._
