<section class="usage">

## Usage

```javascript
var corpus = require( '@stdlib/dist-datasets-spam-assassin' ).SPAM_ASSASSIN;
```

#### corpus()

Returns the [Spam Assassin][@stdlib/datasets/spam-assassin] public mail corpus.

```javascript
var data = corpus();
// returns [{...},{...},...]
```

Each `array` element has the following fields:

-   `id`: message id (relative to message `group`)
-   `group`: message group
-   `checksum`: object containing checksum info
-   `text`: message text (including headers)

The message `group` may be one of the following:

-   `easy-ham-1`: easier to detect non-spam e-mails (2500 messages)
-   `easy-ham-2`: easier to detect non-spam e-mails collected at a later date (1400 messages)
-   `hard-ham-1`: harder to detect non-spam e-mails (250 messages)
-   `spam-1`: spam e-mails (500 messages)
-   `spam-2`: spam e-mails collected at a later date (1396 messages)

The `checksum` object contains the following fields:

-   `type`: checksum type (e.g., MD5)
-   `value`: checksum value

## Notes

-   This package contains distributable files for use in browser environments or as shared ("vendored") libraries in server environments. Each distributable file is a standalone [UMD][umd] bundle which, if no recognized module system is present, will expose bundle contents to the global scope.

-   Each minified bundle has a corresponding [gzip][gzip]-compressed bundle. The [gzip][gzip] compression level for each compressed bundle is `9`, which is the highest (and most optimal) compression level. Deciding between uncompressed and compressed bundles depends on the application and whether compression is handled elsewhere in the application stack (e.g., [nginx][nginx], [CDN][cdn], _et cetera_).

-   While you are **strongly** encouraged to **vendor** bundles and host with a [CDN][cdn]/provider which can provide availability **guarantees**, especially for production applications, bundles are available via [unpkg][unpkg] for quick demos, proof-of-concepts, and instructional material. For example,

    ```html
    <script type="text/javascript" src="https://unpkg.com/@stdlib/dist-datasets-spam-assassin"></script>
    ```

    Please be mindful that [unpkg][unpkg] is a free, best-effort service relying on donated infrastructure which does **not** provide **any** availability guarantees. Under **no** circumstances should you **abuse** or **misuse** the service. You have been **warned**.

-   If you intend on embedding a standalone bundle **within** another bundle, you may need to rename `require` calls within the standalone bundle **before** bundling in order to maintain scoped module resolution. For example, if you plan on using [browserify][browserify] to generate a bundle containing embedded bundles, [browserify][browserify] plugins exist to "de-require" those bundles prior to bundling.

-   The bundles in this package expose the following [stdlib][stdlib] packages:

    -   [@stdlib/datasets/spam-assassin][@stdlib/datasets/spam-assassin]

## Examples

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

```javascript
var corpus = require( '@stdlib/dist-datasets-spam-assassin' ).SPAM_ASSASSIN;

var data;
var i;

data = corpus();
for ( i = 0; i < data.length; i++ ) {
    console.log( 'Character Count: %d', data[ i ].text.length );
}
```

To include the bundle in a webpage,

```html
<script type="text/javascript" src="/path/to/@stdlib/dist-datasets-spam-assassin/build/bundle.min.js"></script>
```

If no recognized module system is present, access bundle contents via the global scope.

```html
<script type="text/javascript">
    // If no recognized module system present, exposed to global scope:
    var dataset = stdlib_datasets_spam_assassin.SPAM_ASSASSIN;
    console.log( dataset() );
</script>
```
