include _includes/_mixins
+section("intro")
p
| This styleguide is loosely based on the concept and principles of
| #[+a("http://bradfrost.com/blog/post/atomic-web-design/") Atomic Design].
| The templates consist of small elements (atoms) which are combined
| and connected to form larger molecules and full components. The site
| is compiled using #[+a("http://harpjs.com/") Harp], a static web
| server with built-in preprocessing. Templates are written entirely in
| #[+a("http://jade-lang.com") Jade] (aka. Pug), a clean,
| whitespace-sensitive templating language that compiles to HTML.
| CSS is written in #[+a("http://sass-lang.com") Sass] and preprocessed
| via Harp, JavaScript is written in ES6 syntax and compiled using
| #[+a("https://babeljs.io") Babel].

| GitHub only allows native embedding of Gists, but Gists are only
| available for users, not organisations. So in order to be able to
| embed examples from spaCy's #[+src(gh("spacy", "examples")) examples],
| we ended up developing our own micro library. A #[code data-gh-embed]
| attribute on the code block, set via the mixin, specifies the file
| to load. The script then fetches the raw text via the GitHub API and
| renders it in the container. This way, the example previews on the
| site are always in sync with the examples in the repository.

p
| The spaCy website is implemented
| in #[+a("https://www.jade-lang.org") Jade (aka Pug)], and is built or
| served by #[+a("(https://harpjs.com") Harp]. Jade is an extensible
| templating language with a readable syntax, that compiles to HTML.
| The website source makes extensive use of Jade mixins, so that the
| design system is abstracted away from the content you're writing. You
| can read more about our approach in our blog post,

+h(3, "jade") Jade conventions
p
| Jade/Pug is a whitespace-sensitive markup language that compiles to
| HTML. Indentation is used to nest elements, and for template logic,
| like #[code if], #[code else] or #[code for], mainly used to iterate
| over objects and arrays in the meta data. It also allows inline
| JavaScript expressions.

| #[+a("https://ines.io/blog/the-ultimate-guide-static-websites-harp-jade") this blog post].
| For more info on the Jade/Pug syntax, check out their
| #[+a("https://pugjs.org") documentation]. In the spacy.io source, we
| use 4 spaces to indent and hard-wrap at 80 characters.

p This is a very short paragraph. It stays inline.
p
| This is a much longer paragraph. It's hard-wrapped at 80 characters to
| make it easier to read on GitHub and in editors that do not have soft
| wrapping enabled. To prevent Jade from interpreting each line as a new
| element, it's prefixed with a pipe and two spaces. This ensures that no
| spaces are dropped – for example, if your editor strips out trailing
| whitespace by default. Inline links are added using the inline syntax,
| like this: #[+a("https://google.com") Google].
+aside("Plain HTML elements used")
+list.o-no-block
+item #[code p]: Regular paragraph.
+item #[code code]: Inline #[code code].
+item #[code em]: #[em Italicized] text.
+item #[code strong]: #[strong Bold] text.
p
| Note that for external links, #[code +a("...")] is used instead
| of #[code a(href="...")] – it's a mixin that takes care of adding all
| required attributes. If possible, always use a mixin instead of
| regular HTML elements. With a few exceptions for practical reasons,
| class names and other HTML attributes should
| #[strong only live in mixins] and not in the site content.

p
| While all page content lives in the #[code .jade] files, article meta
| (page titles, sidebars etc.) is stored as JSON. Each folder contains
| a #[code _data.json] with all required meta for its files. Meta
| information is keyed by the page's filename or slug, and becomes

p
| Long pages with multiple sections are often split into separate
