This is a follow-up to #4632. There were some assumptions in that implementation that did not hold water in all situations.
This commit simplifies the content lazy initalization making it more robust.
Fixes#4664
I eturn either:
1. leaf
2. branch
3. empty string
The above sits well with constructs like:
```
{{ with .BundleType }}
// Now we know it is a bundle
{{ end }}
```
Fixes#4662
The count starts at 0 relative to the shortcode's parent: Either the page or the surrounding shortcode.
Access it in a shortcode like this:
```bash
Ordinal is {{ .Ordinal }}
```
Note that this is a shared ordinal for all shortcodes in the relevant context, so, as an example, you have this in a content page:
```markdown
This is a shortcode:
{{< hello >}}
This is another shortcode:
{{< hugo >}}
The `.Ordinal` you get in the two shortcodes above is 0 and 1.
```
See #3359
In most cases we could delay the content init until rendering time, but there could be use cases where the templates would depend on state set in the shortcodes (.Page.Scratch.Set), so we need to do this early.
See #4632
This resolves some surprising behaviour when reading other pages' content from shortcodes. Before this commit, that behaviour was undefined. Note that this has never been an issue from regular templates.
It will still not be possible to get **the current shortcode's page's rendered content**. That would have impressed Einstein.
The new and well defined rules are:
* `.Page.Content` from a shortcode will be empty. The related `.Page.Truncated` `.Page.Summary`, `.Page.WordCount`, `.Page.ReadingTime`, `.Page.Plain` and `.Page.PlainWords` will also have empty values.
* For _other pages_ (retrieved via `.Page.Site.GetPage`, `.Site.Pages` etc.) the `.Content` is there to use as you please as long as you don't have infinite content recursion in your shortcode/content setup. See below.
* `.Page.TableOfContents` is good to go (but does not support shortcodes in headlines; this is unchanged)
If you get into a situation of infinite recursion, the `.Content` will be empty. Run `hugo -v` for more information.
Fixes#4632Fixes#4653Fixes#4655
For the content from other pages in shortcodes there are some chicken and
egg dependencies that is hard to get around. But we can improve on this by preparing the pages in a certain order:
1. The headless bundles goes first. These are page typically page and image collections..
2. Leaf bundles
3. Regular single pages
4. Branch bundles
