Built-in template functions are available in YAML templates/pages with no extra setup.

• encodeURI(value)
• encodeURIComponent(value)
• decodeURI(value)
• decodeURIComponent(value)

• jsonStringify(value, space = 0)
• toQueryString(object)
• sort(list, key, order = "asc")
• chunk(list, size = 1, pad = false, fillValue = null)
• md(content)

• formatDate(value, format = "YYYYMMDDHHmmss", useUtc = true)
• now(format = "YYYYMMDDHHmmss", useUtc = true)

Supported date tokens:

• YYYY
• MMM
• MM
• DD
• D
• HH
• mm
• ss

sort returns a new array and supports asc/desc order. chunk returns an array of arrays for row-based rendering and can pad the final row. md renders markdown and returns raw HTML content for template insertion.

- rtgl-view:
    - rtgl-text: ${encodeURIComponent(page.title)}
    - rtgl-text: ${jsonStringify(page, 2)}
    - rtgl-text: ${now("YYYYMMDDHHmmss")}

- a href="/search?${toQueryString({ q: page.title, tag: 'docs' })}":
    - rtgl-text: "Search"

- rtgl-text: ${sort(releases.items, "publishedAt", "desc")[0].version}
- rtgl-view:
    - ${md("**Hello** _world_")}

decodeURI and decodeURIComponent return the original input if decoding fails.
