resources.ExecuteAsTemplate	Creates a resource from a Go template, parsed and executed with the given context.			aliases related returnType signatures functions/resources/FromString resource.Resource resources.ExecuteAsTemplate TARGETPATH CONTEXT RESOURCE

Hugo publishes the resource to the target path when you call its.Publish, .Permalink, or .RelPermalink method. The resource is cached, using the target path as the cache key.

Let's say you have a CSS file that you wish to populate with values from your site configuration:

{{< code file=assets/css/template.css lang=go-html-template >}} body { background-color: {{ site.Params.style.bg_color }}; color: {{ site.Params.style.text_color }}; } {{< /code >}}

And your site configuration contains:

{{< code-toggle file=hugo >}} [params.style] bg_color = '#fefefe' text_color = '#222' {{< /code-toggle >}}

Place this in your baseof.html template:

{{ with resources.Get "css/template.css" }}
  {{ with resources.ExecuteAsTemplate "css/main.css" $ . }}
    <link rel="stylesheet" href="{{ .RelPermalink }}">
  {{ end }}
{{ end }}

The example above:

1. Captures the template as a resource
2. Executes the resource as a template, passing the current page in context
3. Publishes the resource to css/main.css

The result is:

{{< code file=public/css/main.css >}} body { background-color: #fefefe; color: #222; } {{< /code >}}
