This allows for constructs like:
```
{{ $filters := slice (images.GaussianBlur 8) (images.Grayscale) (images.Process "jpg q30 resize 200x") }}
{{ $img = $img | images.Filter $filters }}
```
Note that the `action` option in `images.Process` is optional (`resize` in the example above), so you can use the above to just set the target format, e.g.:
```
{{ $filters := slice (images.GaussianBlur 8) (images.Grayscale) (images.Process "jpg") }}
{{ $img = $img | images.Filter $filters }}
```
Fixes#8439
Which supports all the existing actions: resize, crop, fit, fill.
But it also allows plain format conversions:
```
{{ $img = $img.Process "webp" }}
```
Which will be a simple re-encoding of the source image.
Fixes#11483
* Move config loading to the page package
* Fix a lower bound panic for the `:sections` slice syntax.
* Always return the `:title`
* Add some permalinks integration tests
* Also see issues below
Fixes#9448Fixes#11184
See #8523
Allows using permalink configuration for sections (branch bundles) and
also for taxonomy pages. Extends the current permalink configuration to
be able to specified per page kind while also staying backward compatible:
all permalink patterns not dedicated to a certain kind, get automatically
added for both normal pages and term pages.
Fixes#8523
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.

Make sure the context used for timeouts isn't created based on the incoming
context, as we have cases where this can cancel the context prematurely.
Fixes#10789
Applicable to Dart Sass only:
- Sass imports with the .css extension indicate a plain CSS @import.
- Sass imports without the .css extension are imported at compile time.
Fixes#10592
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
But only in the case where we know that we will need to access the Page fragments/tableofcontents.
In normal situations this will spread naturally across the CPU cores, but not in the situation where
`site.RegularPages.Related` gets called as part of e.g. the single template.
```bash
name old time/op new time/op delta
RelatedSite-10 18.0ms ± 2% 11.9ms ± 1% -34.17% (p=0.029 n=4+4)
name old alloc/op new alloc/op delta
RelatedSite-10 38.6MB ± 0% 38.6MB ± 0% ~ (p=0.114 n=4+4)
name old allocs/op new allocs/op delta
RelatedSite-10 117k ± 0% 117k ± 0% +0.23% (p=0.029 n=4+4)
```

Instead of maintaing a list of all CSS units and functions this commit:
* Uses 3 regexps to detect typed CSS values (e.g. `24px`) + properly handle numeric Go types.
* These regexps may have some false positives -- e.g. strings that needs to be quoted.
* For that rare case, you can mark the string with e.g. `"32xxx" | css.Quoted`
* For the opposite case: `"32" | css.Unquoted`
Updates #10632
Variables passed via the hugo:vars function where passed as type string.
This caused problems when using the variables in sass functions because
these expect a specific type. Now we check if the passed variables have
to be quoted and therefore are of type string or if they should not be
quoted and let the type interpretation up to the sass compiler.
Fixes#10632
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.

Note that this is backed by a LRU cache (which we soon shall see more usage of), so if you're a heavy user of cached partials it may be evicted and
refreshed if needed. But in most cases every partial is only invoked once.
This commit also adds a timeout (the global `timeout` config option) to make infinite recursion in partials
easier to reason about.

So you can do `process.env.HUGO_PUBLISHDIR` in your `postcss.config.js` to figure out where Hugo publishes
its files.
Note that the value will always be an absolute file path and will point to a directory on disk even when running `hugo server` in memory mode.
If you write to this folder from PostCSS when running the server, you could run the server with one of these flags:
```
hugo server --renderToDisk
hugo server --renderStaticToDisk
```
Fixes#10554
This commit adds a new `vars` option to both the Sass transpilers (Dart Sass and Libsass).
This means that you can pass a map with key/value pairs to the transpiler:
```handlebars
{{ $vars := dict "$color1" "blue" "$color2" "green" "$font_size" "24px" }}
{{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }}
{{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }}
```
And the the variables will be available in the `hugo:vars` namespace. Example usage for Dart Sass:
```scss
@use "hugo:vars" as v;
p {
color: v.$color1;
font-size: v.$font_size;
}
```
Note that Libsass does not support the `use` keyword, so you need to `import` them as global variables:
```scss
@import "hugo:vars";
p {
color: $color1;
font-size: $font_size;
}
```
Hugo will:
* Add a missing leading `$` for the variable names if needed.
* Wrap the values in `unquote('VALUE')` (Sass built-in) to get proper handling of identifiers vs other strings.
This means that you can pull variables directly from e.g. the site config:
```toml
[params]
[params.sassvars]
color1 = "blue"
color2 = "green"
font_size = "24px"
image = "images/hero.jpg"
```
```handlebars
{{ $vars := site.Params.sassvars}}
{{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }}
{{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }}
```
Fixes#10555
This fixes the cases where
```js

import 'imp3/foo.js';
```
And these files lives in `assets` as:
```
imp2/index.ts
imp3/foo.ts
```
Fixes#10527
We do lazy initialization and (potentially) reuse of an output format's rendered content. We do this evaluation when we
start a new rendering a new output format. There are, however, situation where these borders gets crossed (e.g.
accessing content from another output format). We have a check for this in place for most cases, but not the content
rendering of inner markdown blocks inside shortcodes. This patch applies that same logic to the newly introduced
RenderContent method (which is not available from the templates).
Fixes#10391
Looking at the code as a whole, we ended up with a little to much "buttons". It turns out that doing case insensitive matching (lower both pattern and strings to match) performs just fine. Or at least, it
gives the penalty to the people who uses mixed case filenames.

On Linux, `hugofs.Glob` does not hit any directories which includes
uppercase letters. (This does not happen on macOS.)
Since `resources.GetMatch/Match` uses `Glob`,
```
{{ resources.GetMatch "Foo/bar.css" }}
```
this does not match `assets/Foo/bar.css` .
On the other hand, you can get it with
```
{{ resources.Get "Foo/bar.css" }}
```
Simple sites may only have one css file. Update the replace directive to
correctly match single-file sourcemaps and multi-file sourcemaps.
Verified locally with and without SASS and CSS imports.
Fixes#8174
Same logic as for `index.{js,ts...}` files applies; if both `index.esm.js` and `index.js` exists (unlikely), you need to use the name
with extension when importing, else the `index.js` will win.
Fixes#8631
By using the input map as the basis, which means the hash will not change if we add/rename/remove options.
This happened in Hugo 0.99, as we added a new options. This is unortunate.
Unfortunately this means that the cache keys for PostCSS will change one more time in 0.100, but will be stable going forward.
Note that we have implemented this pattern in all the other resource transformers.
Updates #9787
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.

These are not documented, and they don't belong on Page. We should consider having author a first class citizen of Hugo, but as it is not it's better modelled as a taxonomy.
If set, `key` will be used as the only cache key element for the resource.
The default behaviour is to calculate the key based on the URL and all the options.
This means that you can now do:
```
{{ $cacheKey := print $url (now.Format "2006-01-02") }}
{{ $resource := resource.GetRemote $url (dict "key" $cacheKey) }}
```
Fixes#9755
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
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.

Introduces the Crop method for image processing which implements gift.CropToSize. Also allows a smartCrop without resizing, and updates the documentation.
Fixes#9499
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
In page.NewOutputFormat, we take an output.Format f and use it to
create a page.OutputFormat. If the format is canonical, we assign
the final OutputFormat's Rel to "canonical" rather than using
f.Rel. However, this leads to unexpected behavior for custom
output formats, where a user can define a "rel" for a format
via the config file.
For example, the standard for "humans.txt" files requires using
rel="author" in HTML "link" elements. Meanwhile, humans.txt is
usually the only format used for its content. As a result, for
Hugo configurations that define a humans.txt custom output format,
Hugo will render "link" elements to content in this format with
rel="canonical," rather than "author" as required by the standard.
This commit changes page.NewOutputFormat to check whether a given
format is user defined and, if so, skips assigning Rel to
"canonical," even if isCanonical is true.
Fixes#8030
