Content components

OINK promotes the content components that proved reusable across PGSTY sites into the theme. Each component has a stable authoring API, unique instance IDs, local assets, and a defined safety boundary. Site-specific data widgets remain outside the theme.

Loading model

Interactive shortcodes mark the features used by a page. OINK then adds each required stylesheet or runtime once, even if the page has several component instances. A plain page does not download component code it never uses.

Relative asset and link parameters pass through Hugo’s URL handling, so they remain correct under a subpath baseURL. Component markup also has print, dark-mode, mobile, keyboard, and reduced-motion behavior where applicable.

Asciinema

Use asciinema for a terminal recording stored as a local .cast file:

{{< asciinema
  file="images/install.cast"
  speed="1.5"
  markers="0:Start,1:Done"
>}}

file is required and can also be the first positional argument. The terminal window uses title when supplied and otherwise displays the file value. Supported options are title, theme, fit (width, height, both, or none), autoplay, loop, preload, speed, startAt, poster, cols, rows, idleTimeLimit, pauseOnMarkers, and comma-separated markers.

Keep cast files local for offline use. A remote URL is accepted only when the author explicitly supplies it.

Advanced visualizations

ECharts and Infographic remain Oink content components, but each now has a dedicated section under Advanced. This page keeps the reusable component overview concise and points to the richer examples.

Apache ECharts

Use Apache ECharts for quantitative charts based on structured JSON or YAML. The chart gallery contains several live patterns, and callbacks and trusted code documents the explicit executable-code boundary.

AntV Infographic

Use Infographics with AntV for declarative processes, timelines, cycles, grids, and funnels. The dedicated pages explain template semantics, themes, local-first constraints, and accessible textual fallbacks.

Cards and carousel

doc-card and nav-card share one card implementation. doc-cards and nav-cards create responsive groups of one to four columns. The aliases let an existing site’s content keep its most descriptive name without duplicating markup or styles.

{{< nav-cards cols="3" >}}
  {{< nav-card
    title="Architecture"
    link="/docs/about/architecture/"
    icon="fa-solid fa-diagram-project"
    desc="Understand the build and runtime boundaries."
  >}}
  {{< nav-card
    title="Deployment"
    link="/docs/deploy/"
    badge="Hugo-only"
  >}}Publish the static output.{{< /nav-card >}}
{{< /nav-cards >}}

A card accepts title, link, image, alt, icon, desc, accent, and badge. Its body can contain Markdown links. Tokens such as {version} in desc resolve from site parameters when a matching value exists.

Wrap document cards in doc-carousel to create an accessible horizontal carousel:

{{< doc-carousel label="OINK workflow" >}}
  {{< doc-card title="Write" >}}Create paired content.{{< /doc-card >}}
  {{< doc-card title="Build" >}}Run Hugo Extended.{{< /doc-card >}}
  {{< doc-card title="Verify" >}}Inspect the static site.{{< /doc-card >}}
{{< /doc-carousel >}}

label supplies the carousel’s accessible name. Arrow keys and visible previous/next controls navigate the track; reduced-motion preferences disable unnecessary animation.

Details

details emits native details and summary elements:

{{% details title="Why Hugo-only?" closed="false" %}}
Committed browser assets keep the consuming build reproducible.
{{% /details %}}

title sets the summary. The block is closed by default; set closed=false to render it open.

Tabs

OINK keeps Docsy’s tabpane and tab authoring model while preserving selected=true and whitespace behavior used by imported sites:

{{< tabpane text=true >}}
  {{< tab header="Local" selected=true >}}
  Build with the complete local theme.
  {{< /tab >}}
  {{< tab header="Cloudflare" >}}
  Run the same Hugo command from the source branch.
  {{< /tab >}}
{{< /tabpane >}}

• Local
• Cloudflare

Use text=true for Markdown content; otherwise tabs are syntax-highlighted code. Tab panes also support language-aware persistence, disabled tabs, and right-aligned entries. Generated tab and panel IDs have matching ARIA relationships.

Parameters

param prints a page parameter, falling back to the site parameter of the same name:

Current version: {{< param version >}}

Current version: v0.2.0

The shortcode fails the build when the named parameter does not exist. This is intentional: a missing release or repository value should not silently produce misleading documentation.

Existing rich content

OINK also ships local runtimes for inherited content features:

• fenced mermaid, math, and markmap code blocks;
• swaggerui and redoc API documentation shortcodes;
• Docsy blocks, alerts, image, include, readfile, cards, and other established shortcodes.

See Shortcodes and Diagrams and formulae for the complete authoring reference.

Authoring rules

• Prefer structured data over executable content.
• Give images useful alt text and carousels a meaningful label.
• Do not enable autoplay unless the content genuinely requires it.
• Test several identical instances on one page when creating a new wrapper.
• Verify keyboard navigation, focus visibility, dark and light themes, mobile layout, print output, and reduced-motion behavior.
• Keep business-specific data components in the consuming site.
