svg_tag helper

gistfile1.txt

For a parametrized approach, you can add a helper into ApplicationHelper:

```
  def svg_tag(options = {}, class:)
    tag.svg(xmlns: 'http://www.w3.org/2000/svg', class:, **options) do
      yield if block_given?
    end
  end
```

and then, use `svg_tag` in the views:

```
<%= svg_tag({width: "16", height: "16", fill: "currentColor", viewBox: "0 0 16 16"}, class: "nav-icon bi bi-speedometer") do %>
  '<path d="M8 2a.5.5 0 0 1 .5.5V4a.5.5 0 0 1-1 0V2.5A.5.5 0 0 1 8 2M3.732 3.732a.5.5 0 0 1 .707 0l.915.914a.5.5 0 1 1-.708.708l-.914-.915a.5.5 0 0 1 0-.707M2 8a.5.5 0 0 1 .5-.5h1.586a.5.5 0 0 1 0 1H2.5A.5.5 0 0 1 2 8m9.5 0a.5.5 0 0 1 .5-.5h1.5a.5.5 0 0 1 0 1H12a.5.5 0 0 1-.5-.5m.754-4.246a.39.39 0 0 0-.527-.02L7.547 7.31A.91.91 0 1 0 8.85 8.569l3.434-4.297a.39.39 0 0 0-.029-.518z"/>' +
  '<path fill-rule="evenodd" d="M6.664 15.889A8 8 0 1 1 9.336.11a8 8 0 0 1-2.672 15.78zm-4.665-4.283A11.95 11.95 0 0 1 8 10c2.186 0 4.236.585 6.001 1.606a7 7 0 1 0-12.002 0"/>'
<% end %>
```

Everything at all can be parametrized:

```
<%= svg_tag({width: "16", height: "16", fill: "currentColor", viewBox: "0 0 16 16"}, class: "bi bi-speedometer") do %>
  <%= tag.path(d: "M8 2a.5.5 0 0 1 .5.5V4a.5.5 0 0 1-1 0V2.5A.5.5 0 0 1 8 2M3.732 3.732a.5.5 0 0 1 .707 0l.915.914a.5.5 0 1 1-.708.708l-.914-.915a.5.5 0 0 1 0-.707M2 8a.5.5 0 0 1 .5-.5h1.586a.5.5 0 0 1 0 1H2.5A.5.5 0 0 1 2 8m9.5 0a.5.5 0 0 1 .5-.5h1.5a.5.5 0 0 1 0 1H12a.5.5 0 0 1-.5-.5m.754-4.246a.39.39 0 0 0-.527-.02L7.547 7.31A.91.91 0 1 0 8.85 8.569l3.434-4.297a.39.39 0 0 0-.029-.518z".html_safe) +
        tag.path(fill_rule: "evenodd", d: "M6.664 15.889A8 8 0 1 1 9.336.11a8 8 0 0 1-2.672 15.78zm-4.665-4.283A11.95 11.95 0 0 1 8 10c2.186 0 4.236.585 6.001 1.606a7 7 0 1 0-12.002 0".html_safe) %>
<% end %>
```

All of the above was just a mind exercise and saved here just in case it will be 
necessary some day.

That said, the best way is like FontAwesome - having packed their SVG icons with 
helpers to get them accessed.

Or, like Bootstrap Icons, providing their SVG in raw HTML - with 2 clicks they are 
copied into the view.
