Markdoc functions

Markdoc functions add powerful capabilities to your Markdown content, enabling conditional logic and data manipulation.

Functions are typically used in two main ways:

1. Conditional rendering: Inside {% if %} tags to control whether a block of content is displayed based on variable values or other conditions.
2. Direct output: Within {% ... %} delimiters to directly output a computed value into the content.

Call functions using a syntax similar to programming languages:

{% functionName(argument1, argument2, ...) %}

Arguments can be literal values (strings, numbers, booleans), variables (like $frontmatter.seo.title or $rbac.teams), or results of other functions.
