Zola (static site generator with Rust) の template html で body class を生成する / Generate body class with zola template html

取り敢えず、使えそうな感じにはなった。他にいい方法無いのか？
現在、category, tag, layout についてはテストできていない。

{# body class を生成 #}
{% set body_plink = "" %}

{% if page is defined %}
  {% set body_plink = page.permalink %}
{% elif section is defined %}
  {% set body_plink = section.permalink %}
{% endif %}

{% set body_classes = [] %}

{# permalink を分解して path[0] を取得 #}
{% set plink_parts = body_plink | split(pat="/") %}
{% set path0 = plink_parts | nth(n=3) | default(value="") %}
{% if path0 != "" %}
  {% set body_classes = body_classes | concat(with=["path0-" ~ path0]) %}
{% else %}
  {% set body_classes = body_classes | concat(with=["home"]) %}
{% endif %}

{# slug によるクラス #}
{% if section is defined and section.slug is defined %}
  {% set body_classes = body_classes | concat(with=["section-" ~ section.slug]) %}
{% elif page is defined and page.slug is defined %}
  {% set body_classes = body_classes | concat(with=["page-" ~ page.slug]) %}
{% endif %}

{# カテゴリクラスを追加（例: category-news） #}
{% if page is defined and page.taxonomies is defined %}
  {% for cat in page.taxonomies.categories | default(value=[]) %}
    {% set body_classes = body_classes | concat(with=["category-" ~ cat]) %}
  {% endfor %}
{% endif %}

{# タグクラスを追加（例: tag-web, tag-dev） #}
{% if page is defined and page.taxonomies is defined %}
  {% for tag in page.taxonomies.tags | default(value=[]) %}
    {% set body_classes = body_classes | concat(with=["tag-" ~ tag]) %}
  {% endfor %}
{% endif %}

{# レイアウト（テンプレート）クラスを追加（例: layout-page） #}
{% if page is defined and page.template is defined %}
  {% set body_classes = body_classes | concat(with=["layout-" ~ page.template]) %}
{% elif section is defined and section.template is defined %}
  {% set body_classes = body_classes | concat(with=["layout-" ~ section.template]) %}
{% endif %}

{# HTML 出力 #}
<body class="{{ body_classes | join(sep=' ') }}">

{# body class を生成 #}

{% set body_plink = "" %}
