## Usage

```javascript
var acronym = require( '@stdlib/string/acronym' );
```

#### acronym( str\[, options] )

Generates an acronym for a given string.

```javascript
var out = acronym( 'the quick brown fox' );
// returns 'QBF'

out = acronym( 'Hard-boiled eggs' );
// returns 'HBE'
```

The function accepts the following `options`:

-   **stopwords**: list of custom stop words. If not specified, the function uses a default set of stop words from the English language that were deemed words one would likely want to exclude from the acronym generation (a subset of the stop words from [@stdlib/datasets/stopwords-en][@stdlib/datasets/stopwords-en]).

By default, the function uses a list of common English stop words. To use a custom list, set the `stopwords` option.

```javascript
var out = acronym( 'the quick brown fox', {
    'stopwords': []
});
// returns 'TQBF'

out = acronym( 'the quick brown fox', {
    'stopwords': [ 'the', 'quick', 'brown', 'fox' ]
});
// returns ''
```

### Usage

```text
Usage: acronym [options] [<string>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --stopwords str       Comma-separated list of custom stop words.
         --split sep           Delimiter for stdin data. Default: '/\\r?\\n/'.

<section class="notes">

### Notes

-   If the split separator is a [regular expression][mdn-regexp], ensure that the `split` option is either properly escaped or enclosed in quotes.

    ```bash
    # Not escaped...
    $ echo -n $'quick brown fox\nAlpha-Centauri' | acronym --split /\r?\n/

    # Escaped...
    $ echo -n $'quick brown fox\nAlpha-Centauri' | acronym --split /\\r?\\n/
    ```

-   The implementation ignores trailing delimiters.

<!-- CLI usage examples. -->

<section class="examples">

### Examples

```bash
$ acronym 'the quick brown fox'
QBF
```

To use as a [standard stream][standard-streams],

```bash
$ echo -n 'the quick brown fox'' | acronym
QBF
```

By default, when used as a [standard stream][standard-streams], the implementation assumes newline-delimited data. To specify an alternative delimiter, set the `split` option.

```bash
$ echo -n 'quick brown fox\tAlpha-Centauri' | acronym --split '\t'
QBF
AC
```
