Primary motivation is documentation, but it will also hopefully simplify the code.
Also,
* Lower case the default output format names; this is in line with the custom ones (map keys) and how
it's treated all the places. This avoids doing `stringds.EqualFold` everywhere.

This also speeds up situations where you only need the fragments/toc and not the rendered content, e.g. Related
with fragments type indexing:
```bash
name old time/op new time/op delta
RelatedSite-10 12.3ms ± 2% 10.7ms ± 1% -12.95% (p=0.029 n=4+4)
name old alloc/op new alloc/op delta
RelatedSite-10 38.6MB ± 0% 38.2MB ± 0% -1.08% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
RelatedSite-10 117k ± 0% 115k ± 0% -1.36% (p=0.029 n=4+4)
```
Fixes#10750
The main topic of this commit is that you can now index fragments (content heading identifiers) when calling `.Related`.
You can do this by:
* Configure one or more indices with type `fragments`
* The name of those index configurations maps to an (optional) front matter slice with fragment references. This allows you to link
page<->fragment and page<->page.
* This also will index all the fragments (heading identifiers) of the pages.
It's also possible to use type `fragments` indices in shortcode, e.g.:
```
{{ $related := site.RegularPages.Related .Page }}
```
But, and this is important, you need to include the shortcode using the `{{<` delimiter. Not doing so will create infinite loops and timeouts.
This commit also:
* Adds two new methods to Page: Fragments (can also be used to build ToC) and HeadingsFiltered (this is only used in Related Content with
index type `fragments` and `enableFilter` set to true.
* Consolidates all `.Related*` methods into one, which takes either a `Page` or an options map as its only argument.
* Add `context.Context` to all of the content related Page API. Turns out it wasn't strictly needed for this particular feature, but it will
soon become usefil, e.g. in #9339.

This fixes a regression introduced in v0.93.0 where previously, a
mixed-case key for lineNos would be successfully parsed. This change
moves the configuration key lowercasing step into the configuration
normalization stage, which is called whether the highlighting config
is being parsed from a `string` or a `map`.
Fixes#10682
* Removes any surrounding paragraph nodes
* And transfers any attributes from the surrounding paragraph down to the image node
* Adds IsBlock and Ordinal (zero based) field to the image context passed to the image render hooks
IsBlock is set to true if `wrapStandAloneImageWithinParagraph = false` and the image's parent node has only one child.

It has been deprecated for a long time, its v1 version is not maintained anymore, and there are many known issues. Goldmark should be
a mature replacement by now.
Closes#9934
Note that we will now fail if `inlineImports` is enabled and we cannot resolve an import.
You can work around this by either:
* Use url imports or imports with media queries.
* Set `skipInlineImportsNotFound=true` in the options
Also get the argument order in the different NewFileError* funcs in line.
Fixes#9895
* Redo the server error template
* Always add the content file context if relevant
* Remove some now superflous error string matching
* Move the server error template to _server/error.html
* Add file context (with position) to codeblock render blocks
* Improve JS build errors
Fixes#9892Fixes#9891Fixes#9893
* Add file context to minifier errors when publishing
* Misc fixes (see issues)
* Allow custom server error template in layouts/server/error.html
To get to this, this commit also cleans up and simplifies the code surrounding errors and files. This also removes the usage of `github.com/pkg/errors`, mostly because of https://github.com/pkg/errors/issues/223 -- but also because most of this is now built-in to Go.

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.

This ommmit contains some security hardening measures for the Hugo build runtime.
There are some rarely used features in Hugo that would be good to have disabled by default. One example would be the "external helpers".
For `asciidoctor` and some others we use Go's `os/exec` package to start a new process.
These are a predefined set of binary names, all loaded from `PATH` and with a predefined set of arguments. Still, if you don't use `asciidoctor` in your project, you might as well have it turned off.
You can configure your own in the new `security` configuration section, but the defaults are configured to create a minimal amount of site breakage. And if that do happen, you will get clear instructions in the loa about what to do.
The default configuration is listed below. Note that almost all of these options are regular expression _whitelists_ (a string or a slice); the value `none` will block all.
```toml
[security]
enableInlineShortcodes = false
[security.exec]
allow = ['^dart-sass-embedded$', '^go$', '^npx$', '^postcss$']
osEnv = ['(?i)^(PATH|PATHEXT|APPDATA|TMP|TEMP|TERM)$']
[security.funcs]
getenv = ['^HUGO_']
[security.http]
methods = ['(?i)GET|POST']
urls = ['.*']
```
Currently the generated `<pre>` element isn't fully accessible as it can't be focused by keyboard users.
To make this fully accessible, the attribute `tabindex="0"` should be added to the `<pre>` tag.
Closes#7194
The main motivation behind this is simplicity and correctnes, but the new small config library is also faster:

go-org PrettyRelativeLinks rewrites relative org links by
- adding `../` in front
- removing any `.org` suffix
This was meant to play well with hugo pretty urls (which pretty much renders
posts in a subdirectory without the file suffix) and allow use of normal org
file links to reference other posts.
There's a lot of edge cases I didn't consider and multiple bug reports in
go-org [1] later I don't think the complexity of handling those edge cases is
worth it - so let's disable it.

E.g.:
```
> foo
> bar
{.myclass}
```
There are some current limitations: For tables you can currently only apply it to the full table, and for lists the ul/ol-nodes only, e.g.:
```
* Fruit
* Apple
* Orange
* Banana
{.fruits}
* Dairy
* Milk
* Cheese
{.dairies}
{.list}
```
Fixes#7548
- Add support for pretty urls [1]. Rewrite file links:
1. replace the `.org` extension with `/` (`/foo.org` -> `/foo/`)
2. prefix unrooted links with `../` as relative links start in the fake
subdirectory `/foo/` rather than `/`
- Fix case-sensitivity of org drawer `🔚`

This change is mostly motivated to get a more stable CI build (we're building the Hugo site there, with Instagram and Twitter shortcodes sometimes failing).

Avoid creating a local copy of the highlight configuration when no
options are passed.

Fill the .TableOfContents template variable when writing Asciidoc content.
This is done by letting Asciidoc render its TOC as HTML, then extract this
HTML rendered TOC, parse it into a tableofcontents.Root and finally remove
it from the HTML content.
This aims to stay in the logic that the Asciidoc parsing is entirely done
by the external helper.
See #1687
Applicable when autoHeadingIDType is either `github` or `github-ascii`.
When autoHeadingIDType is `blackfriday`, the existing code removes
trailing whitespace while iterating through the characters, using
a boolean "futureDash" mechanism.
Fixes#6798
- Add support for #+MACRO
- fix a bug with #+LINK (edge case, should never happen anyways :TM:)
- Make title export optional (add export option)
- Remove cosmetic whitespace added by go-org (for easier visual
diffing) inside p tags (<p>\nfoo\n</p> => <p>foo</p>)
(should make `white-space: pre` on p look more in line with expectations)
- implement table separators via multiple tbodies (the html spec is ok with
that)
This commit solves the relative path problem with asciidoctor tooling. An include will resolve relatively, so you can refer easily to files in the same folder.
Also `asciidoctor-diagram` and PlantUML rendering works now, because the created temporary files will be placed in the correct folder.
This patch covers just the Ruby version of asciidoctor. The old AsciiDoc CLI EOLs in Jan 2020, so this variant is removed from code.
The configuration is completely rewritten and now available in `config.toml` under the key `[markup.asciidocext]`:
```toml
[markup.asciidocext]
extensions = ["asciidoctor-html5s", "asciidoctor-diagram"]
workingFolderCurrent = true
trace = true
[markup.asciidocext.attributes]
my-base-url = "https://example.com/"
my-attribute-name = "my value"
```
- backends, safe-modes, and extensions are now whitelisted to the popular (ruby) extensions and valid values.
- the default for extensions is to not enable any, because they're all external dependencies so the build would break if the user didn't install them beforehand.
- the default backend is html5 because html5s is an external gem dependency.
- the default safe-mode is safe, explanations of the modes: https://asciidoctor.org/man/asciidoctor/
- the config is namespaced under asciidocext_config and the parser looks at asciidocext to allow a future native Go asciidoc.
- `uglyUrls=true` option and `--source` flag are supported
- `--destination` flag is required
Follow the updated documentation under `docs/content/en/content-management/formats.md`.
This patch would be a breaking change, because you need to correct all your absolute include pathes to relative paths, so using relative paths must be configured explicitly by setting `workingFolderCurrent = true`.
