This commit adds a "cache potential" column when running `hugo --templateMetrics --templateMetricsHints`.
This is only calculated when `--templateMetricsHints` is set, as these calculations has an negative effect on the other timings.
This gives a value for partials only, and is a number between 0-100 that indicates if `partial` can be replaced with `partialCached`.
100 means that all execution of the same partial resulted in the same output.
You should do some manual research before going "all cache".
Add template function that will build a string from the given format
string and arguments, then log it to ERROR. This has an intended
side-effect of causing the build to fail, when executed.
Resolves#3817
Changes fall into one of the following:
- gofmt -s
- receiver name is inconsistent
- omit unused 2nd value from range
- godoc comment formed incorrectly
- err assigned and not used
- if block ends with a return statement followed by else
Add a template function that allows conversion to float. This is
useful, for example, when passing aspect ratios into templates,
which tend to not be integers.
Fixes#3307
Ceil and Floor are frontends for the stdlib math functions. The Round
implementation is essentially the same thing except that the Go stdlib
doesn't include a Round implementation in a stable release yet. I've
included the Round function slated for Go 1.10.
Fixes#3883
This closes#98, even if this commit does not do full content text search.
We may revisit that problem in the future, but that deserves its own issue.
Fixes#98
These funcs were added during the move to namespaces but were
undocumented. This commit fixes the order of the arguments and adds the
funcs to the method mapping.
And use it in `eq` and `ne` so `Page` values can be compared directly in the templates without thinking about it being a `Page` or a `PageOutput` wrapper.
Fixes#3807
As pointed out by the linter, some exported functions and types are
missing doc comments.
The linter warnings have been reduced from 194 to 116.
Not all missing comments have been added in this commit though.
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.
```

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.

```
{{ $src := .Get "src" }}

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:

The current "rendering language" is needed outside of Site. This commit moves the Language type to the helpers package, and then used to get correct correct language configuration in the markdownify template func.

Work In Progress!
This commit makes a rework of the build and rebuild process to better suit a multi-site setup.
This also includes a complete overhaul of the site tests. Previous these were a messy mix that
were testing just small parts of the build chain, some of it testing code-paths not even used in
"real life". Now all tests that depends on a built site follows the same and real production code path.

This commit also consolidates URLs on Node vs Page, so now .Permalink should be interoperable.
Note that this implementations should be fairly short-livded, waiting for #2297, but the API should be stable.
Setting the language to use when loading the language bundles just doesn't work.

Implements:
* support to render:
* content/post/whatever.en.md to /en/2015/12/22/whatever/index.html
* content/post/whatever.fr.md to /fr/2015/12/22/whatever/index.html
* gets enabled when `Multilingual:` is specified in config.
* support having language switchers in templates, that know
where the translated page is (with .Page.Translations)
(when you're on /en/about/, you can have a "Francais" link pointing to
/fr/a-propos/)
* all translations are in the `.Page.Translations` map, including the current one.
* easily tweak themes to support Multilingual mode
* renders in a single swift, no need for two config files.
Adds a couple of variables useful for multilingual sites
Adds documentation (content/multilingual.md)
Added language prefixing for all URL generation/permalinking see in the
code base.
Implements i18n. Leverages the great github.com/nicksnyder/go-i18n lib.. thanks Nick.
* Adds "i18n" and "T" template functions..
These functions allow trivial escaping and unescaping of HTML entities,
and make it far easier to compose other functions for the creation of
parameterised URLs.
Add logic to tpl.humanize such that it understands input of int literals
or strings which represent an integer. When tpl.humanize sees this type
of input, it will use inflect.Ordinalize as opposed to the standard
inflect.Humanize.

The query function will take a set of parameters specified like a dict and return a url.Values object which can be .Encode'd into a query string.
Example:
<a href="http://www.google.com?{{ (querify "q" "test" "page" 3).Encode | safeHTML }}">Search</a>
Returns:
<a href="http://www.google.com?page=3&q=test">Search</a>
Closes#2257
Returns true if a given field value that is a slice / array of strings, integers or floats contains elements in common with the matching value. It follows the same rules as the intersect function.
Closes#1945
While sorting on data sources with missing fields, a panic can occur in
pairList.Less if `Interface()` is called on a invalid `reflect.Value`.
This commit detects an invalid Value and replacing it with a zero value
for the comparison.
This also includes a refactor of the hugofs package and its usage.
The motivation for that is:
The Afero filesystems are brilliant. Hugo's way of adding a dozen of global variables for the different filesystems was a mistake. In readFile (and also in some other places in Hugo today) we need a way to restrict the access inside the working dir. We could use ioutil.ReadFile and implement the path checking, checking the base path and the dots ("..") etc. But it is obviously better to use an Afero BasePathFs combined witha ReadOnlyFs. We could create a use-once-filesystem and handle the initialization ourselves, but since this is also useful to others and the initialization depends on some other global state (which would mean to create a new file system on every invocation), we might as well do it properly and encapsulate the predefined set of filesystems. This change also leads the way, if needed, to encapsulate the file systems in a struct, making it possible to have several file system sets in action at once (parallel multilanguage site building? With Moore's law and all...)
Fixes#1551
To strip away any HTML. May be useful for the .Title in head etc.
People may shoot themself in the foot with this, maybe ...
The replacement function is pretty fast.
The `intersect` function uses `in` to avoid adding duplicates to the
resulting set. We were passing `reflect.Value` items when we should
have been using `Value.Interface()` to send the actual data structure.
This fixes that.
See #1952
This uses the Emoji map from https://github.com/kyokomi/emoji -- but with a custom replacement implementation.
The built-in are fine for most use cases, but in Hugo we do care about pure speed.
The benchmarks below are skewed in Hugo's direction as the source and result is a byte slice,
Kyokomi's implementation works best with strings.
Curious: The easy-to-use `strings.Replacer` is also plenty fast.
