Best way to handle data attributes in Slim

There are multiple ways in Slim

As Hash

Attributes which will be hyphenated if a Hash is given (e.g. data={a:1,b:2} will render as data-a="1" data-b="2")
Use it directly as "mu is too short" mentioned, quite intuitive.
```
a data-title="help" data-content="foo"
```

Use Ruby code. I often do this and rarely above.

= link_to 'foo', bar_path, data: {a: 'a', b: 'b'}

.your-class*{data: {first_attribute: 'first value', second_attribute: 'second value'} }

Will produce

<div class="your-class" data-first_attribute="first value" data-second_attribute="second value"></div>

Use the splat operator:

h1#section-title*{'data-url'=>'test', 'data-id'=>'test'} = @project.name
