    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/slice-base-str2slice
```

</section>

<section class="usage">

## Usage

```javascript
var str2slice = require( '@stdlib/slice-base-str2slice' );
```

<a name="main"></a>

#### str2slice( str )

Parses a string-serialized [`Slice`][@stdlib/slice/ctor] object.

```javascript
var s = str2slice( 'Slice(0,5,1)' );
// returns <Slice>

var v = s.start;
// returns 0

v = s.stop;
// returns 5

v = s.step;
// returns 1
```

The function returns `null` if provided an invalid string.

```javascript
var s = str2slice( 'Slice(foo,bar)' );
// returns null
```

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   The string serialization format must match that of a [`Slice`][@stdlib/slice/ctor] object.

    ```javascript
    var Slice = require( '@stdlib/slice-ctor' );

    var s = new Slice( 2, 10, 1 );
    // returns <Slice>

    var str = s.toString();
    // returns 'Slice(2,10,1)'
    ```

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var str2slice = require( '@stdlib/slice-base-str2slice' );

var s = str2slice( 'Slice(null,null,null)' );
console.log( 'start: %s. stop: %s. step: %s.', s.start, s.stop, s.step );
// => 'start: null. stop: null. step: null.'

s = str2slice( 'Slice(2,10,2)' );
console.log( 'start: %s. stop: %s. step: %s.', s.start, s.stop, s.step );
// => 'start: 2. stop: 10. step: 2.'

s = str2slice( 'Slice(10,null,-2)' );
console.log( 'start: %s. stop: %s. step: %s.', s.start, s.stop, s.step );
// => 'start: 10. stop: null. step: -2.'

s = str2slice( 'Slice(null,null,2)' );
console.log( 'start: %s. stop: %s. step: %s.', s.start, s.stop, s.step );
// => 'start: null. stop: null. step: 2.'

s = str2slice( 'Slice(foo,bar)' );
console.log( s );
// => null
