And make both .Resources and resources implement it.
This gets us 2 new methods/functions, so you can now also do:
* .Resources.Get
* resources.ByType
Note that GetRemote is not covered by this interface, as that is only available as a global template function.
Fixes#8653
This commit adds a .Data object (a map with `Body`, `StatusCode` etc.) to the .Err returned from `resources.GetRemote`, which means you can now do:
```
{{ with .Err }}
{{ range $k, $v := .Data }}
{{ end }}
{{ end }}
```
Fixes#9708
* @warn and Sass deprecations are printed as WARN
* @debug is currently logged as INFO (needs the `--verbose` flag). We may adjust this if it gets too chatty.
Fixes#9683
This commit prevents the most commons case of infinite recursion in link render hooks when the `linkify` option is enabled (see below). This is always a user error, but getting a `stack overflow` (the current stack limit in Go is 1 GB on 64-bit, 250 MB on 32-bit) error isn't very helpful. This fix will not prevent all such errors, though, but we may do better once #9570 is in place.
So, these will fail:
```
<a href="{{ .Destination | safeURL }}" >{{ .Text | markdownify }}</a>
<a href="{{ .Destination | safeURL }}" >{{ .Text | .Page.RenderString }}</a>
```
`.Text` is already rendered to `HTML`. The above needs to be rewritten to:
```
<a href="{{ .Destination | safeURL }}" >{{ .Text | safeHTML }}</a>
<a href="{{ .Destination | safeURL }}" >{{ .Text | safeHTML }}</a>
```
Fixes#8959
For the Position in code blocks we try to match the .Inner with the original source. This isn't always possible.
This commits avoids panics in these situations.
Fixes#9627
You can now create custom hook templates for code blocks, either one for all (`render-codeblock.html`) or for a given code language (e.g. `render-codeblock-go.html`).
We also used this new hook to add support for diagrams in Hugo:
* Goat (Go ASCII Tool) is built-in and enabled by default; just create a fenced code block with the language `goat` and start draw your Ascii diagrams.
* Another popular alternative for diagrams in Markdown, Mermaid (supported by GitHub), can also be implemented with a simple template. See the Hugo documentation for more information.

I have had this living in a separate branch for now, but we need this in the main branch sooner rather than later.
One big advantage of this is that integration tests can live in any package, not just hugolib.
We changed the signature to `func(...interface{}) (interface{}, error)` some time ago, but sadly we had no test for this for `apply`. Now we do.
Fixes#9393
When a template calls the .Translations function and a
Hugo environment is using multiple output formats,
a template that calls methods like .Summary and .Len on
each translation will unexpectedly show empty return
values for these methods.
This is because each pageOutput's ContentProvider is
assigned to a page.NopPage in newPageOutput. When
*HugoSites.render assigns pageContentOutputs to
pageOutputs in *pageState.shiftToOutputFormat, it
reuses pageContentOutputs from other pageOutputs,
leaving some pageContentOutputs as NopPages. While this
approach conserves resources, sometimes it means that
a template will unexpectedly call a method on a
pageContentOutput that is actually a NopPage.
In the case of ContentProvider methods called on
translations for alternative output formats, the methods
were called on NopPages.
This change introduces LazyContentProvider, which
performs late initialization when one of its methods is
called. This way, we can reuse content in "normal" cases
but ensure that ContentProvider methods work as expected
when a pageOutput is not assigned a pageContentOutput
during the initial pre-render phase.
Fixes#8919
