# with-copyable
Modifier for adding copy-to-clipboard functionality to any component to allow
the user to easily copy specified text to their clipboard by clicking on
something. Mainly an Ember flavoured wrapper for
[Clipboard.js](https://clipboardjs.com/) which the modifier uses for all its
functionality.
You can either explicitly specify the content to be copied to the users
clipboard using the first (and only) parameter but if this is omitted it will
use the content (`innerText`) of the DOM element it is attached to.
Usually you will want to provide a `success` and `error` callback which you
can provide with named parameters. An escape hatch through to Clipboard.js
options is also provided via the `options` named parameter.
```hbs preview-template
<figure>
<figcaption>Explicitly specifying the text to be copied as the first parameter</figcaption>
<button
{{with-copyable "Copied text"
success=(action (mut this.copied) value="text")
error=(noop)
}}
type="button"
>Click me</button>
<pre>Clipboard Contents:
{{this.copied}}</pre>
</figure>
```
```hbs preview-template
<figure>
<figcaption>Defaulting to the innerText of the DOM element</figcaption>
<button
{{with-copyable success=(action (mut this.copied) value="text")}}
type="button"
>Click <span><br />me</span></button>
<pre>Clipboard Contents:
{{this.copied}}</pre>
</figure>
```
The Clipboard.js class is provided via a `clipboard/os` Service, also includes
a `clipboard/local-storage` Service that automatically replaces the OS based
clipboard during testing to enable you to assert for text that would be copied
to the clipboard. During acceptance testing there is a specific step
specifically for this so you don't have to think about it:
```gherkin acceptance-test
Scenario:
When I click copyButton
Then I copied "stringToCopy"
```
