Calling many functions without comments

[szepeviktor]

Hello! I see 30 lines of function calls with ever-opening/closing comments. https://github.com/conedevelopment/cone-site/blob/main/src/_includes/partial/meta.html#L1-L30

How is it possible to write blocks of Nunjucks code without comment signs on each line?

It is not possible to have "multiline code block execution" in Nunjucks. In the example you linked to, it's possible to condense

{% if page.url.length > 1 %}
    {% set pageTitle = title + ' - ' + site.name %}
{% else %}
    {% set pageTitle = site.name %}
{% endif %}
{% if metaTitle %}
    {% set pageTitle = metaTitle %}
{% endif %}

into:

{% set pageTitle = metaTitle ? metaTitle : (page.url.length > 1 ? (title + ' - ' + site.name) : site.name) %}

If you don't like to have too much logic in your Nunjucks templates, you can choose to encapsulate this logic in a {% macro %}, eg:

{% macro pageTitle(title, isIndex, siteTitle) %}
{% if isIndex and title %}
  {{ title | safe }} - {{ siteTitle | safe }}
{% elif title %}
  {{ title | safe }}
{% elif siteTitle %}
  {{ siteTitle | safe }}
{% endif %}
{% endmacro %}

{# usage:  {{ pageTitle(title, page.url.length > 1, site.name) }} #}
