prettier-plugin-twig-enhancements

Subtle enhancements for Prettier Twig plugin, prettier-plugin-twig-melody.

Note: This is a plugin for prettier-plugin-twig-melody, not a Prettier plugin.

I made this originally to format YAML frontmatter in Nunjucks templates (since Nunjucks is similar to Twig in syntax) and to address this issue. However it appears the Twig plugin isn't well compatible with Nunjucks, so I'm not using this currently.

<h1>Hello, world!</h1>

<input type="email" name="email" id="email" class="form-control form-control--large form-control--email">
