Content includes

The :::include block inlines content from a local file or remote URL directly into the page at render time. The included content is processed through the full pipeline and baked into the cached page.

Syntax

::: include
path/to/file.md
:::

The optional ttl=N modifier sets the parent page cache TTL in seconds if no ttl: is set in the page front matter. Useful for pages that include frequently updated remote content.

Path resolution

Starts with / - absolute from docroot
Starts with http:// or https:// - remote URL fetch
Otherwise - relative to the current .md file directory

Content handling by file type

.md files: Front matter stripped, body rendered as Markdown inline. The included file's title and layout front matter are ignored - only the body is used.
Code files (.sh, .pl, .py, .yml, .json, .css etc.): Wrapped in a fenced code block with the appropriate language identifier.
.html files: Inserted bare - assumed to be a valid HTML fragment.
Unknown extensions: Wrapped in <pre> with HTML entities escaped.

Examples

Include a local Markdown partial:

::: include
partials/shared-note.md
:::

Include a remote file, refresh every 5 minutes:

::: include ttl=300
https://raw.githubusercontent.com/owner/repo/main/CHANGELOG.md
:::

Include a code file (renders as a syntax-highlighted code block):

::: include
/examples/config-sample.yml
:::

Error handling

If a local file is missing or a remote fetch fails, the block renders as a silent span with class include-error and a data-src attribute recording the failed source path. A warning is written to the error log. Expose errors during development:

.include-error::before {
  content: "include failed: " attr(data-src);
  color: red;
  display: block;
}

Notes

Includes are single-pass only - :::include inside an included .md file is not processed. This prevents infinite loops.
Remote includes are fetched at render time and baked into the cache. The page cache TTL controls how often remote content is refreshed.
The ttl=N modifier only sets the TTL if no ttl: key is present in the page front matter. Front matter always takes priority.
For frequently updated remote content, combine with ttl: in front matter or the ttl=N modifier.
