Before this commit, you would have to use page bundles to do image processing etc. in Hugo.
This commit adds
* A new `/assets` top-level project or theme dir (configurable via `assetDir`)
* A new template func, `resources.Get` which can be used to "get a resource" that can be further processed.
This means that you can now do this in your templates (or shortcodes):
```bash
{{ $sunset := (resources.Get "images/sunset.jpg").Fill "300x200" }}
```
This also adds a new `extended` build tag that enables powerful SCSS/SASS support with source maps. To compile this from source, you will also need a C compiler installed:
```
HUGO_BUILD_TAGS=extended mage install
```
Note that you can use output of the SCSS processing later in a non-SCSSS-enabled Hugo.
The `SCSS` processor is a _Resource transformation step_ and it can be chained with the many others in a pipeline:
```bash
{{ $css := resources.Get "styles.scss" | resources.ToCSS | resources.PostCSS | resources.Minify | resources.Fingerprint }}
<link rel="stylesheet" href="{{ $styles.RelPermalink }}" integrity="{{ $styles.Data.Digest }}" media="screen">
```
The transformation funcs above have aliases, so it can be shortened to:
```bash
{{ $css := resources.Get "styles.scss" | toCSS | postCSS | minify | fingerprint }}
<link rel="stylesheet" href="{{ $styles.RelPermalink }}" integrity="{{ $styles.Data.Digest }}" media="screen">
```
A quick tip would be to avoid the fingerprinting part, and possibly also the not-superfast `postCSS` when you're doing development, as it allows Hugo to be smarter about the rebuilding.
Documentation will follow, but have a look at the demo repo in https://github.com/bep/hugo-sass-test
New functions to create `Resource` objects:
* `resources.Get` (see above)
* `resources.FromString`: Create a Resource from a string.
New `Resource` transformation funcs:
* `resources.ToCSS`: Compile `SCSS` or `SASS` into `CSS`.
* `resources.PostCSS`: Process your CSS with PostCSS. Config file support (project or theme or passed as an option).
* `resources.Minify`: Currently supports `css`, `js`, `json`, `html`, `svg`, `xml`.
* `resources.Fingerprint`: Creates a fingerprinted version of the given Resource with Subresource Integrity..
* `resources.Concat`: Concatenates a list of Resource objects. Think of this as a poor man's bundler.
* `resources.ExecuteAsTemplate`: Parses and executes the given Resource and data context (e.g. .Site) as a Go template.

Sets Page.markup earlier (as early as possible, when the page is
loaded). Sets it once and only once, removing many redundant calls
to determineMarkupType().
This kills a sleeping bug that was avoided by the parts of the
code depending on this value making those redundant calls.
This is a follow-up to #4632. There were some assumptions in that implementation that did not hold water in all situations.
This commit simplifies the content lazy initalization making it more robust.
Fixes#4664
The count starts at 0 relative to the shortcode's parent: Either the page or the surrounding shortcode.
Access it in a shortcode like this:
```bash
Ordinal is {{ .Ordinal }}
```
Note that this is a shared ordinal for all shortcodes in the relevant context, so, as an example, you have this in a content page:
```markdown
This is a shortcode:
{{< hello >}}
This is another shortcode:
{{< hugo >}}
The `.Ordinal` you get in the two shortcodes above is 0 and 1.
```
See #3359
This resolves some surprising behaviour when reading other pages' content from shortcodes. Before this commit, that behaviour was undefined. Note that this has never been an issue from regular templates.
It will still not be possible to get **the current shortcode's page's rendered content**. That would have impressed Einstein.
The new and well defined rules are:
* `.Page.Content` from a shortcode will be empty. The related `.Page.Truncated` `.Page.Summary`, `.Page.WordCount`, `.Page.ReadingTime`, `.Page.Plain` and `.Page.PlainWords` will also have empty values.
* For _other pages_ (retrieved via `.Page.Site.GetPage`, `.Site.Pages` etc.) the `.Content` is there to use as you please as long as you don't have infinite content recursion in your shortcode/content setup. See below.
* `.Page.TableOfContents` is good to go (but does not support shortcodes in headlines; this is unchanged)
If you get into a situation of infinite recursion, the `.Content` will be empty. Run `hugo -v` for more information.

This applies to both regular templates and shortcodes. So, if the site language is French and the output format is AMP, this is the (start) of the lookup order for the home page:
1. index.fr.amp.html
2. index.amp.html
3. index.fr.html
4. index.html
5. ...
Fixes#3360
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
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.

This commit fixes two different, but related issues:
1) Live-reload when a new shortcode was defined in the content file before the shortcode itself was created.
2) Live-reload when a newly defined shortcode changed its "inner content" status.
This commit also improves the shortcode related error messages to include the full path to the content file in question.
Fixes#3156
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
Add DocumentName (path to the file being rendered) to RenderingContext
and use that information to include the path in the error print.
See #2399Closes#2567
This is the nth attempt to fix an issue by changing the placeholder token pattern, but
now we actually have tests for all the historic trouble cases.
Fixes#2223
This is needed to make shortcode users happy with the new multilanguage support,
but it will also solve many other related posts about "stuff not available in the shortcode".
We will have to revisit this re the handler chain at some point, but that will be easier
now as the integration test story has improved so much.
As part of this commit, the site-building tests in page_test.go is refreshed, they now
tests for all the rendering engines (when available), and all of them now uses the
same code-path as used in production.
Fixes#1229Fixes#2323
Fixes ##1076
This issue was introduced as a fix to shortcode not working in RST.
One could argue that Blackfriday and friends should handle `#` in titles, but that will be a discussion
for another day.
The new placeholder pattern should be RST safe and work with titles.
And now with a test so this doesn't break again.

If Page.Markup was not set by the user, it will now be set after
guessing from the file extension. This means, Page.Markup will be set in
any case. It can be used by a theme to differentiate between markup
types.
Fixes#1950
We can of course skip reading the entire byte slice again and again.
This was a slip in the original implementation; functionally the same,
but is slightly faster, esp. for larger data sets with many shortcodes:
```
benchmark old ns/op new ns/op delta
BenchmarkReplaceShortcodeTokens-4 15505 14753 -4.85%
benchmark old allocs new allocs delta
BenchmarkReplaceShortcodeTokens-4 1 1 +0.00%
benchmark old bytes new bytes delta
BenchmarkReplaceShortcodeTokens-4 3072 3072 +0.00%
```
It would be helpful to know whether a shortcode was called with positional or
named parameters. This commit adds a boolean `IsNamedParams` property to the
`ShortcodeWithPage` struct.
Currently a `[]byte` copy is returned. In most cases this is the safe thing to do, but we should just modify/grow the slice as needed.
This is faster and consumes less memory:
```
benchmark old ns/op new ns/op delta
BenchmarkReplaceShortcodeTokens-4 7350 4419 -39.88%
benchmark old allocs new allocs delta
BenchmarkReplaceShortcodeTokens-4 5 1 -80.00%
benchmark old bytes new bytes delta
BenchmarkReplaceShortcodeTokens-4 4816 1152 -76.08%
```
This commit is aso a small spring cleaning of duplicated code in the different `PageConvert` methods.
Fixes#1516
Even as a copy at the end is needed, this consumes way less memory on Go 1.4.2:
```benchmark old ns/op new ns/op delta
BenchmarkParsePage 145979 139964 -4.12%
BenchmarkReplaceShortcodeTokens 633574 631946 -0.26%

```

This commit replaces the regexp driven `replaceShortcodeTokens` with a handwritten one.
It wasnt't possible to handle the p-tags case without breaking performance.
This fix actually improves in that area:

First step to use initialisms that golint suggests,
for example:
Line 116: func GetHtmlRenderer should be GetHTMLRenderer
as see on http://goreportcard.com/report/spf13/hugo
Thanks to @bep for the idea!
Note that command-line flags (cobra and pflag)
as well as struct fields like .BaseUrl and .Url
that are used in Go HTML templates need more work
to maintain backward-compatibility, and thus
are NOT yet dealt with in this commit.
First step in fixing #959.
The flag `HTML_SMARTYPANTS_ANGLED_QUOTES` was added to Blackfriday on Black Friday. This configures rendering of double quotes as angled left and right quotes («
»).
Typical use cases would be either or, or combined, but never in the same
document. As an example would be a person from Norway; he has a blog in both
English and Norwegian (his native tongue); he would then configure Blackfriday
to use angled quotes for the Norwegian section, but keep them as reqular
double quotes for the English.
This commit adds configuration support for this new flag, configuration that can be set in the site configuration, but overridden in page front matter.
Fixes#605
- `.Ref` and `.RelRef` take a reference (the logical filename for a
page, including extension and/or a document fragment ID) and return
a permalink (or relative permalink) to the referenced document.
- If the reference is a page name (such as `about.md`), the page
will be discovered and the permalink will be returned: `/about/`
- If the reference is a page name with a fragment (such as
`about.md#who`), the page will be discovered and used to add the
`page.UniqueID()` to the resulting fragment and permalink:
`/about/#who:deadbeef`.
- If the reference is a fragment and `.*Ref` has been called from
a `Node` or `SiteInfo`, it will be returned as is: `#who`.
- If the reference is a fragment and `.*Ref` has been called from
a `Page`, it will be returned with the page’s unique ID:
`#who:deadbeef`.
- `.*Ref` can be called from either `Node`, `SiteInfo` (e.g.,
`Node.Site`), `Page` objects, or `ShortcodeWithPage` objects in
templates.
- `.*Ref` cannot be used in content, so two shortcodes have been
created to provide the functionality to content: `ref` and `relref`.
These are intended to be used within markup, like `[Who]({{% ref
about.md#who %}})` or `<a href="{{% ref about.md#who %}}">Who</a>`.
- There are also `ref` and `relref` template functions (used to create
the shortcodes) that expect a `Page` or `Node` object and the
reference string (e.g., `{{ relref . "about.md" }}` or `{{
"about.md" | ref . }}`). It actually looks for `.*Ref` as defined on
`Node` or `Page` objects.
- Shortcode handling had to use a *differently unique* wrapper in
`createShortcodePlaceholder` because of the way that the `ref` and
`relref` are intended to be used in content.
Some newly added shortcode tests compared maps in assertions.
This failed on Travis, as iteration order isn't guaranteed for maps since Go 1.
This commit fixes that by do a sort of the keys in the shortcode String() function.
This commit contains a restructuring and partial rewrite of the shortcode handling.
Prior to this commit rendering of the page content was mingled with handling of the shortcodes. This led to several oddities.
The new flow is:
1. Shortcodes are extracted from page and replaced with placeholders.
2. Shortcodes are processed and rendered
3. Page is processed
4. The placeholders are replaced with the rendered shortcodes
The handling of summaries is also made simpler by this.
This commit also introduces some other chenges:
1. distinction between shortcodes that need further processing and those who do not:
* `{{< >}}`: Typically raw HTML. Will not be processed.
* `{{% %}}`: Will be processed by the page's markup engine (Markdown or (infuture) Asciidoctor)
The above also involves a new shortcode-parser, with lexical scanning inspired by Rob Pike's talk called "Lexical Scanning in Go",
which should be easier to understand, give better error messages and perform better.
2. If you want to exclude a shortcode from being processed (for documentation etc.), the inner part of the shorcode must be commented out, i.e. `{{%/* movie 47238zzb */%}}`. See the updated shortcode section in the documentation for further examples.
The new parser supports nested shortcodes. This isn't new, but has two related design choices worth mentioning:
* The shortcodes will be rendered individually, so If both `{{< >}}` and `{{% %}}` are used in the nested hierarchy, one will be passed through the page's markdown processor, the other not.
* To avoid potential costly overhead of always looking far ahead for a possible closing tag, this implementation looks at the template itself, and is branded as a container with inner content if it contains a reference to `.Inner`
Fixes#565Fixes#480Fixes#461
And probably some others.
If content pages are fully rendered in a list page, footnotes that use
the same reference (`[^fn]`) will have duplicated anchors. This change
builds on #526 to put the page filename (`Page.File.Name`) as part of
the anchor for a footnote.
This would fix discussion [116](http://discuss.gohugo.io/t/footnote-references-are-duplicated-on-list-pages/116).
It started with wanting to move templates in template bundles and the
rest followed. I did my best to start grouping related functions
together, but there are some that I missed. There is also the method
Urlize that seems to be a special function used in both worlds. I'll
need to revisit this method.
