Assemble: Multiple points of content insertion in layout?

问题

All assemble users who uses layouts knows that "{{> body }}" marks the point of insertion of contents of any page who uses the layout. But is it possible to define multiple points of insertions, instead of tossing everything at where the {{> body }} is?

For instance, in my page I would like to define a specific piece of javascript, but I like that custom javascript to be at the very bottom of the page along with out javascript tags. If it only puts everything where the {{> body }} is, this is not possible, since the script will just be appended to the content.

In other words, it would be useful to have {{> script }} or even customizable tags marking different points of insertion, and in the page using the layout, these tags are specifically defined.

Above is my ideal use case, does anyone know if assemble supports anything like this?

@Xavier_Ex check out the assemble handlebars helper repo https://github.com/assemble/example-layout-helpers

We added some layout helpers about a month ago that allow you to "extend" a layout and include different content sections. Notice that you'll have to include your layout as a partial in the assemble gruntfile setup for this to work properly...

assemble: {
  options: {
    flatten: true,
    assets: 'docs/assets',
    partials: ['src/includes/*.hbs', 'src/layouts/*.hbs'],
    layout: false,
    data: ['src/data/*.{json,yml}', 'package.json']
  },
  pages: {
    src: 'src/*.hbs',
    dest: 'docs/'
  }
}

Layout (default.hbs)...

<!DOCTYPE html>
<html lang="en">
  <head>
    {{#block "head"}}
    <meta charset="UTF-8">
    <title>{{title}} | {{site.title}}</title>
    <link rel="stylesheet" href="{{assets}}/{{stylesheet}}.css">
    <link rel="stylesheet" href="{{assets}}/github.css">
    {{/block}}
  </head>
  <body {{#is stylesheet "bootstrap"}}style="padding-top: 40px;"{{/is}}>

    {{#block "header"}}
    {{! Navbar
    ================================================== }}
    {{> navbar }}
    {{/block}}


    {{! Subhead
    ================================================== }}
    <header class="{{#is stylesheet "bootstrap"}}jumbotron {{/is}}{{#is stylesheet "assemble"}}masthead {{/is}}subhead">
      <div class="container">
        <div class="row">
          <div class="col col-lg-12">
            <h1> DOCS / {{#if title}}{{ uppercase title }}{{else}}{{ uppercase basename }}{{/if}} </h1>
          </div>
        </div>
      </div>
    </header>

    {{! Page content
    ================================================== }}
    {{#block "body"}}
    <div class="container">
      <div class="panel panel-docs">
        {{> body }}
      </div>
    </div>
    {{/block}}

    {{#block "script"}}
    <script src="{{assets}}/highlight.js"></script>
    <script src="{{assets}}/holder.js"></script>
    {{/block}}
  </body>
</html>

Some page

{{#extend "default"}}
    {{#content "head"}}
        <link rel="stylesheet" href="assets/css/home.css" />
    {{/content}}

    {{#content "body"}}
        <h2>Welcome Home</h2>

        <ul>
            {{#items}}
                <li>{{.}}</li>
            {{/items}}
        </ul>
    {{/content}}

    {{#content "script"}}
        <script src="assets/js/analytics.js"></script>
    {{/content}}
{{/extend}}

Hope this helps.
