This is a recent regression in Hugo, where we have started to produce `/page/30/index.json` when the main output format (usually `HTML`) is set up with pagination.
For JSON this is potentially lot of superflous work and hurts performance.
This commit reinstates the earlier behaviour: We only create paginators if in use in the main output format.
And add a test for it to prevent this from happening again.
Fixes#4890
Before this commit, you would have to use page bundles to do image processing etc. in Hugo.
This commit adds
* A new `/assets` top-level project or theme dir (configurable via `assetDir`)
* A new template func, `resources.Get` which can be used to "get a resource" that can be further processed.
This means that you can now do this in your templates (or shortcodes):
```bash
{{ $sunset := (resources.Get "images/sunset.jpg").Fill "300x200" }}
```
This also adds a new `extended` build tag that enables powerful SCSS/SASS support with source maps. To compile this from source, you will also need a C compiler installed:
```
HUGO_BUILD_TAGS=extended mage install
```
Note that you can use output of the SCSS processing later in a non-SCSSS-enabled Hugo.
The `SCSS` processor is a _Resource transformation step_ and it can be chained with the many others in a pipeline:
```bash
{{ $css := resources.Get "styles.scss" | resources.ToCSS | resources.PostCSS | resources.Minify | resources.Fingerprint }}
<link rel="stylesheet" href="{{ $styles.RelPermalink }}" integrity="{{ $styles.Data.Digest }}" media="screen">
```
The transformation funcs above have aliases, so it can be shortened to:
```bash
{{ $css := resources.Get "styles.scss" | toCSS | postCSS | minify | fingerprint }}
<link rel="stylesheet" href="{{ $styles.RelPermalink }}" integrity="{{ $styles.Data.Digest }}" media="screen">
```
A quick tip would be to avoid the fingerprinting part, and possibly also the not-superfast `postCSS` when you're doing development, as it allows Hugo to be smarter about the rebuilding.
Documentation will follow, but have a look at the demo repo in https://github.com/bep/hugo-sass-test
New functions to create `Resource` objects:
* `resources.Get` (see above)
* `resources.FromString`: Create a Resource from a string.
New `Resource` transformation funcs:
* `resources.ToCSS`: Compile `SCSS` or `SASS` into `CSS`.
* `resources.PostCSS`: Process your CSS with PostCSS. Config file support (project or theme or passed as an option).
* `resources.Minify`: Currently supports `css`, `js`, `json`, `html`, `svg`, `xml`.
* `resources.Fingerprint`: Creates a fingerprinted version of the given Resource with Subresource Integrity..
* `resources.Concat`: Concatenates a list of Resource objects. Think of this as a poor man's bundler.
* `resources.ExecuteAsTemplate`: Parses and executes the given Resource and data context (e.g. .Site) as a Go template.

This should allow for less duplication of templates. Before this commit it was possible to override the content page of a given page/section, but only one page at a time.
Full "template sets" can now be inherited by setting `type: blog` etc. in the section content page's front matter, and that type will be considered when looking for layouts for all pages in that section.
For nested sections, it will use consider both `type` set in the current section first, then `type` set in the first section below home, e.g. `/docs`.
This commit also adds a new Page method: `FirstSection`. This navigates up to the first section below home (e.g. `/docs`). For the home page it will return itself.
Fixes#4891
In Hugo 0.42, this could lead to errors of type `runtime error: invalid memory address or nil pointer dereference` in some rare situations.
Note that this was also an issue before 0.42, but the symptom was then potentially stale list content on rebuilds on content changes.
This commit also improves the above error message.
Fixes#4845
This commit adds support for theme composition and inheritance in Hugo.
With this, it helps thinking about a theme as a set of ordered components:
```toml
theme = ["my-shortcodes", "base-theme", "hyde"]
```
The theme definition example above in `config.toml` creates a theme with the 3 components with presedence from left to right.
So, Hugo will, for any given file, data entry etc., look first in the project, and then in `my-shortcode`, `base-theme` and lastly `hyde`.
Hugo uses two different algorithms to merge the filesystems, depending on the file type:
* For `i18n` and `data` files, Hugo merges deeply using the translation id and data key inside the files.
* For `static`, `layouts` (templates) and `archetypes` files, these are merged on file level. So the left-most file will be chosen.
The name used in the `theme` definition above must match a folder in `/your-site/themes`, e.g. `/your-site/themes/my-shortcodes`. There are plans to improve on this and get a URL scheme so this can be resolved automatically.
Also note that a component that is part of a theme can have its own configuration file, e.g. `config.toml`. There are currently some restrictions to what a theme component can configure:
* `params` (global and per language)
* `menu` (global and per language)
* `outputformats` and `mediatypes`
The same rules apply here: The left-most param/menu etc. with the same ID will win. There are some hidden and experimental namespace support in the above, which we will work to improve in the future, but theme authors are encouraged to create their own namespaces to avoid naming conflicts.
A final note: Themes/components can also have a `theme` definition in their `config.toml` and similar, which is the "inheritance" part of this commit's title. This is currently not supported by the Hugo theme site. We will have to wait for some "auto dependency" feature to be implemented for that to happen, but this can be a powerful feature if you want to create your own theme-variant based on others.

So that a timeout warning does appear if it does happen
especially on a slow machine with soft floating-point CPU.
Special thanks to @bep for the solution.
See #4672
Sets Page.markup earlier (as early as possible, when the page is
loaded). Sets it once and only once, removing many redundant calls
to determineMarkupType().
This kills a sleeping bug that was avoided by the parts of the
code depending on this value making those redundant calls.
There have been one report of a site with truncated `.Content` after the Hugo `0.40.1` release.
This commit fixes this so that race should not be possible anymore. It also adds a stress test with focus on content rendering and multiple output formats.
Fixes#4706
Having them in separate files should make maintainance easier.
When adding new or making changes to the templates:
```bash
mage generate
```
This will get the Go code in sync.
Fixes#4457
This bug was introduced in Hugo 0.40. It is when you use the `<!--more-->` summary marker.
Note that this affects the word stats only. The related `PlainWords`, `Plain`, `Content` all return correct values.
Fixes#4675Fixes#4682
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
Fixes#4632
