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.

The existing endpoint will be retired and removed on November 23, 2021.

This is a backward compatible change.
The existing endpoint requires a single parameter: the id of the tweet.
The new endpoint requires two parameters: the id of the tweet, and the
user with whom it is associated. For the moment, if you supply the wrong
user, the request will be redirected (with a small delay) to the correct
user/id pair. This behavior is undocumented, but we will take advantage
of it as Hugo site authors transition to the new syntax.
{{< tweet 1453110110599868418 >}} --> works, throws warning, deprecate at some point
{{< tweet user="SanDiegoZoo" id="1453110110599868418" >}} --> new syntax
Fixes#8130
* Fix: updated date logic in opengraph template
* Updated date logic in schema template
* Reformatted opengraph and schema
* Wrapped PublishDate and Lastmod in with
When inside front matter you specified series with spaces,
then the opengraph template wouldn't detect other articles,
because in `.Site.Taxonomies.series` they are stored by
urlized key.
Example:
```yaml
# in front matter
series:
- My Series
```
```gohtml
{{/* in a template */}}
{{- $series := index .Site.Taxonomies.series$name }}
{{/* was resolved to */}}
{{- $series := index {'my-series': ...} "MySeries" }}
```
Added a Vimeo EnableDNT privacy option to the Hugo config. This will enable the Vimeo 'Do Not Track' flag when either Vimeo shortcode tempalte options are used. When enabled, it will force the Vimeo player to be blocked from tracking any session data, including all cookies and stats.
Fixes#7700
The rss templates had some tab characters mixed in with the spaces.
Additionally there would end up being trailing whitespace in output
rss feeds, which looks red in git diff.
.Lastmod is the time at which the website was most recently updated,
rather than .Date which is the time at which the website content file
was created.
This is a big commit, but it deletes lots of code and simplifies a lot.
* Resolving the template funcs at execution time means we don't have to create template clones per site
* Having a custom map resolver means that we can remove the AST lower case transformation for the special lower case Params map
Not only is the above easier to reason about, it's also faster, especially if you have more than one language, as in the benchmark below:
```
name old time/op new time/op delta
SiteNew/Deep_content_tree-16 53.7ms ± 0% 48.1ms ± 2% -10.38% (p=0.029 n=4+4)
name old alloc/op new alloc/op delta
SiteNew/Deep_content_tree-16 41.0MB ± 0% 36.8MB ± 0% -10.26% (p=0.029 n=4+4)
name old allocs/op new allocs/op delta
SiteNew/Deep_content_tree-16 481k ± 0% 410k ± 0% -14.66% (p=0.029 n=4+4)
```
This should be even better if you also have lots of templates.
Closes#6594
Add an optional "title" attribute to the iframe in the vimeo shortcode. If one is not given, the title attribute will default to "vimeo video". It is imperative for iframes to have a non-empty "title" attribute in order to meet WCAG2.0 accessibility guidelines https://www.w3.org/TR/WCAG20-TECHS/H64.
This means that you now can do:
{{< vidur 9KvBeKu false true 32 3.14 >}}
And the boolean and numeric values will be converted to `bool`, `int` and `float64`.
If you want these to be strings, they must be quoted:
{{< vidur 9KvBeKu "false" "true" "32" "3.14" >}}
Fixes#6371
This is preparation for #6041.
For historic reasons, the code for bulding the section tree and the taxonomies were very much separate.
This works, but makes it hard to extend, maintain, and possibly not so fast as it could be.
This simplification also introduces 3 slightly breaking changes, which I suspect most people will be pleased about. See referenced issues:
This commit also switches the radix tree dependency to a mutable implementation: github.com/armon/go-radix.
Fixes#6154Fixes#6153Fixes#6152
When using a html link checker with Hugo, this template consistently causes errors, as it renders `href=""` attributes when next/previous is disabled.
This change makes it so that the `href` attribute is not rendered at all if `HasNext` is false - which is better semantically, and makes link checking far easier.
The `safeHTMLAttr` function operates on a full attribute definition, not
just within the attribute value.
Docs: https://gohugo.io/functions/safehtmlattr/
For `opengraph.html`, run the whole `content` HTML attribute through
`safeHTMLAttr`. That will preserve `+` signs in formatted dates.
For `vimeo_simple.html`, `safeHTMLAttr` was in the context of an
attribute value, thus having no effect. In this case we could replace it
with `safeURL`, but since the code is coming from an API it is safer to
just let Go's template engine sanitize the value as it already does with
`provider_url`.
Fixes#5236 (no need to change Go upstream)
Related to #5246
* Rewind paginator for server mode
* Add some more related tests.
* Replace the clumsy scratch constructs in internal paginator template with variables
See #5825
The main motivation of this commit is to add a `page.Page` interface to replace the very file-oriented `hugolib.Page` struct.
This is all a preparation step for issue #5074, "pages from other data sources".
But this also fixes a set of annoying limitations, especially related to custom output formats, and shortcodes.
Most notable changes:
* The inner content of shortcodes using the `{{%` as the outer-most delimiter will now be sent to the content renderer, e.g. Blackfriday.
This means that any markdown will partake in the global ToC and footnote context etc.
* The Custom Output formats are now "fully virtualized". This removes many of the current limitations.
* The taxonomy list type now has a reference to the `Page` object.
This improves the taxonomy template `.Title` situation and make common template constructs much simpler.
