See which template is used by Hugo

Cool - Thx for sharing and your very good post!

I prefer to see the chosen templates and partials as comments in the html.
Include e.g.
{{ <!-- _default/terms.html --> | safeHTML }}

or

{{ `<!-- partials/head.meta.html -->` | safeHTML }}

in the templates and partials.

To keep track in the blocks:

{{- block "main" . }}
  {{ `<!-- block main _default/baseof.html  -->` | safeHTML }}
  {{- partial "main.blog.date.html"         . -}}
  {{- partial "main.toc.single.html"        . -}}
  {{ `<!-- back in _default/baseof.html  -->` | safeHTML }}
  {{- .Content -}}
{{- end }}

I had no chance to figure out the lookup order without tracing it via those comments…
