This works for the `title` func and the other places where Hugo makes title case.
* AP style (new default)
* Chicago style
* Go style (what we have today)
Fixes#989
This enables `AND` (`intersect`) and `OR` (`union`) filters when combined with `where`.
Example:
```go
{{ $pages := where .Site.RegularPages "Type" "not in" (slice "page" "about") }}
{{ $pages := $pages | union (where .Site.RegularPages "Params.pinned" true) }}
{{ $pages := $pages | intersect (where .Site.RegularPages "Params.images" "!=" nil) }}
```
The above fetches regular pages not of `page` or `about` type unless they are pinned. And finally, we exclude all pages with no `images` set in Page params.
Fixes#3174
* Improve the built-in Disqus template
Set `disqus_identifier`, `disqus_title`, and `disqus_url`
only if the user has explicitly provided them.
Do not load Disqus when the website is previewed locally,
otherwise it is very confusing.
* Use disqus_config instead of three global variables
https://help.disqus.com/customer/portal/articles/472098-javascript-configuration-variables
Unsupported types are currently silently ignored by IsSet. An earlier
attempt was made to solve the issue by returning an error. That attempt
was reverted since it broke some existing themes.
So instead, we'll log an error. Hopefully, people will stop using IsSet
in this way, and we can eventually return an error outright.
Updates #3092
This commit allows shortcode per output format, a typical use case would be the special AMP media tags.
Note that this will only re-render the "overridden" shortcodes and only in pages where these are used, so performance in the normal case should not suffer.
Closes#3220
- Move the main GetCSV and GetJSON into data.go.
- Add error returns to GetCSV and GetJSON.
- Add http client to Namespace for test mocking.
- Send accept headers on remote requests. Fixes#3395
- Return an error on non-2XX HTTP response codes and don't retry.
- Move cache tests to cache_test.go.
As a first step to remove the hard ties between `tplimpl` and the different namespace packages.
The `lang` package is used as the first example use case.
See #3042
This commit moves almost all of the template functions into separate
packages under tpl/ and adds a namespace framework. All changes should
be backward compatible for end users, as all existing function names in
the template funcMap are left intact.
Seq and DoArithmatic have been moved out of the helpers package and into
template namespaces.
Most of the tests involved have been refactored, and many new tests have
been written. There's still work to do, but this is a big improvement.
I got a little overzealous and added some new functions along the way:
- strings.Contains
- strings.ContainsAny
- strings.HasSuffix
- strings.TrimPrefix
- strings.TrimSuffix
Documentation is forthcoming.
Fixes#3042
For pages with translations, add links with hreflang attributes to the
default sitemap template. This helps Google to show the correct
language page in its search results. The syntax used is based on
Google's example at [1].
Also update the sitemap template docs to reflect the changes in the
default template.

Most obvius benefit of this is to include CSS partials with css file suffix into HTML templates.
A valid workaround would be to rename the file `mystyles.html`, but that doesn't work too good for external editors etc.
The css partial is a method used in some themes before Hugo 0.20, but then it stopped working.
This commit reintroduces that behaviour.
Note that the regular layout lookups for text templates, i.e. "single.json" will be
prefixed with "_text/" on lookup and will only match in the text collection.
Fixes#3273
Before this commit, Hugo used `html/template` for all Go templates.
While this is a fine choice for HTML and maybe also RSS feeds, it is painful for plain text formats such as CSV, JSON etc.
This commit fixes that by using the `IsPlainText` attribute on the output format to decide what to use.
A couple of notes:
* The above requires a nonambiguous template name to type mapping. I.e. `/layouts/_default/list.json` will only work if there is only one JSON output format, `/layouts/_default/list.mytype.json` will always work.
* Ambiguous types will fall back to HTML.
* Partials inherits the text vs HTML identificator of the container template. This also means that plain text templates can only include plain text partials.
* Shortcode templates are, by definition, currently HTML templates only.

Add a new rssLimit site configuration option with default of 15. Prior
to this fix, you could create your own RSS feed to override the default
limit of 15, but we still had a hardcoded limit of 50 items set in
`hugolib.renderRSS()`.
With this option in place, the `range first 15 .Data.Pages` logic is no
longer hardcoded into the embedded RSS template.
Because the size of the slice passed to the template is now limited to
rssLimit instead of 50, this commit is a breaking change for sites
with a custom RSS template that expects more than 15 items.
Fixes#3035
Allow all nodes/pages to use date-related OpenGraph meta tags, not
only sites which are using the as-of-yet unfinished .Site.Authors
functionality.
Improve compliance of tags with Facebook's OpenGraph docs for the
"website" and "article" types[0][1]. Also, use the proper tag for
modification date (og:update_time vs article:modified_time).
Generate date published using either .PublishDate or .Date, and use
.Lastmod for modification date, which can use the new enableGitInfo
functionality from Hugo 0.18, but seamlessly falls back to .Date if
the site does not have this enabled/supported.

Note that this looks like overkill for just the logger, and that is correct,
but this will make sense once we start with the template handling etc.
Updates #2701
This commit adds a truncate template function for safely truncating text without
breaking words. The truncate function is HTML aware, so if the input text is a
template.HTML it will be truncated without leaving broken or unclosed HTML tags.
{{ "this is a very long text" | truncate 10 " ..." }}
{{ "With [Markdown](/markdown) inside." | markdownify | truncate 10 }}
This commit fixes the base template lookup order to match the behaviour of regular templates.
```
1. <current-path>/<template-name>-baseof.<suffix>, e.g. list-baseof.<suffix>.
2. <current-path>/baseof.<suffix>
3. _default/<template-name>-baseof.<suffix>, e.g. list-baseof.<suffix>.
4. _default/baseof.<suffix>
For each of the steps above, it will first look in the project, then, if theme is set,
in the theme's layouts folder.
```
Fixes#2783
There are currently several Params and case related issues floating around in Hugo.
This is very confusing for users and one of the most common support questions on the forum.
And while there have been done some great leg work in Viper etc., this is of limited value since this and similar doesn't work:
`Params.myCamelCasedParam`
Hugo has control over all the template method invocations, and can take care of all the lower-casing of the map lookup keys.
But that doesn't help with direct template lookups of type `Site.Params.TWITTER_CONFIG.USER_ID`.
This commit solves that by doing some carefully crafted modifications of the templates' AST -- lowercasing the params keys.
This is low-level work, but it's not like the template API wil change -- and this is important enough to defend such "bit fiddling".
Tests are added for all the template engines: Go templates, Ace and Amber.

Add imageConfig function which calls image.DecodeConfig and returns the height, width and color mode of the image. (#2677)
This allows for more advanced image shortcodes and templates such as those required by AMP.
layouts/shortcodes/amp-img.html
```
{{ $src := .Get "src" }}
{{ $config := imageConfig (printf "/static/%s" $src) }}
<amp-img src="{{$src}}"
height="{{$config.Height}}"
width="{{$config.Width}}"
layout="responsive">
</amp-img>

tpl/template_funcs.go:1019:3: the surrounding loop is unconditionally terminated
source/lazy_file_reader.go:66:5: err != nil is always true for all possible
values ([nil:error] != [nil:error])
All config variables starts with low-case and uses camelCase.
If there is abbreviation at the beginning of the name, the whole
abbreviation will be written in low-case.
If there is abbreviation at the end of the name, the
whole abbreviation will be written in upper-case.
For example, rssURI.
The gain, given the "real sites benchmark" below, is obvious:
```
benchmark old ns/op new ns/op delta

* Make the type/var names more specific. They live in the test namespace, but there are other tests there.
* Camel case variable
