Shirone Markdown Enhancements
2026-08-19GuideDemoMarkdownExtensionsThemeShirone

Shirone provides a collection of theme-exclusive Markdown extensions and custom syntax containers. Built on top of our native unified AST processing pipeline, all extensions render into accessible, semantic HTML during site build time with zero client JavaScript hydration overhead and 100% M3E design token alignment.

File Trees#

File Trees turn multi-level project structures, source hierarchies, and terminal directory outputs into compact, interactive tree views with automatic extension icons, diff highlighting, and collapsible branches.

1. Nested List Syntax (:::file-tree)#

Use the :::file-tree block directive when writing the file hierarchy directly as a Markdown nested list.

:::file-tree{title="Shirone source tree"}
- src
  - components/
    - ++ Navigation.svelte # added component
    - -- Button.astro # removed component
  - content
    - posts/
      - markdown-enhancements.md
  - layouts/
    - PostLayout.astro
  - plugins
    - markdown/
      - rehype-file-tree.mjs
  - styles
    - markdown/
      - trees.css
  - **content.config.ts** # important file
- public/
  - favicon.svg
- package.json

      • markdown
        • trees.css
    • content.config.tsimportant file
  • public
    • favicon.svg
  • package.json

Authoring Rules & Markers#

  • Diff States: Prefix an item with ++ (green background & badge) or -- (red background & strikethrough) to highlight changes.
  • Comments: Any text following a # is rendered as a muted, right-aligned inline comment.
  • Emphasis: Wrap names in **bold** to give key files prominent visual weight.
  • Collapsible Folders: Directories inferred from nested list items start expanded by default. Add a trailing slash (e.g. components/) to create a collapsed directory that readers can expand on click or via keyboard navigation.

2. Terminal Output Syntax (```file-tree)#

When you already have directory tree text generated from command-line tools like tree, paste it directly into a file-tree fenced code block. Both Unicode branch characters (├──, └──, │) and ASCII branches are automatically parsed.

```file-tree title="Build output" icon="simple"
dist
├── _astro/
│   ├── index.css
│   └── page.js
└── favicon.ico
```
Build output
  • dist
    • _astro
      • index.css
      • page.js
    • favicon.ico

Configuration Options#

  • title="string": Sets a custom header title and accessible label for the tree.
  • icon="colored" | "simple": Choose between multi-color extension icons (colored, default) or minimal monochrome icons (simple).

Code Trees#

Interactive Code Trees pair a multi-level file hierarchy navigation pane on the left with instant code panel switching on the right. They provide an IDE-like reading experience for multi-file examples, modules, or whole directory walk-throughs.

1. Container Syntax (:::code-tree)#

Combine multiple fenced code blocks within a :::code-tree block directive. Each code block specifies its path via title="path/to/file".

:::code-tree{title="Shirone Component Demo" height="380px" entry="src/Button.svelte"}
```svelte title="src/Button.svelte"
<script lang="ts">
  let { label = "Click me" } = $props();
</script>


<button class="m3-btn">{label}</button>
```


```stylus title="src/styles/button.styl"
.m3-btn
  background: var(--primary)
  color: var(--on-primary)
  border-radius: var(--shape-corner-m)
```


```json title="package.json"
{
  "name": "button-demo",
  "version": "1.0.0"
}
```
:::
Shirone Component Demo
src/Button.svelte
<script lang="ts">
  let { label = "Click me" } = $props();
</script>


<button class="m3-btn">{label}</button>

Configuration & Markers#

  • title="string": Sets the header title and accessible label for the code tree.
  • height="string": Sets the height for the desktop view (default 420px, e.g. 380px, 26rem).
  • entry="filepath": Specifies which file is active upon first load.
  • icon="colored" | "simple": Switch between colorful or minimal monochrome file icons.
  • :active: Place :active on any fenced code block to designate it as the default active tab.

2. Local Directory Auto-Import (@[code-tree])#

Point directly to any local directory path in the workspace to automatically scan and generate an interactive code tree at build time without manually copying file contents.
