wtf enqueue

// parent theme
use Roots\Sage\Assets;
function assets() {
  $path_to_main_css = Assets\asset_path('styles/main.css'); // http://192.168.10.55/wch/[wp](http://codex.wordpress.org/Plugin_API/Action_Reference/wp)-content/themes/roots-course-wch/dist/styles/main-5386939dee.css
  [wp_enqueue_style](http://codex.wordpress.org/Function_Reference/wp_enqueue_style)('sage/css', $path_to_main_css, false, null);
}
[add_action](http://codex.wordpress.org/Function_Reference/add_action)('[wp_enqueue_scripts](http://codex.wordpress.org/Plugin_API/Action_Reference/wp_enqueue_scripts)', __NAMESPACE__ . '\\assets', 100);

// resulting html in child theme
<link rel='stylesheet' id='wch/css-css'  href='http://192.168.10.55/wch/[wp](http://codex.wordpress.org/Plugin_API/Action_Reference/wp)-content/themes/roots-course-wch/dist/styles/main.css?ver=1.0.0' type='text/css' media='all' />
