DESCRIPTION

This role defines the interface for quick yukkitext helpers. Each plugin implementing this role may provide code references for embedding content in yukkitext using a special {{...}} notation.

REQUIRED METHODS

An implementor must provide the following methods.

format_helpers

This must return a reference to hash mapping quick helper names to method names that may be called to handle them.

The names may be any text that does not contain a colon (":").

The methods will be called with the following parameters:

context

The curent Yukki::Web::Context object.

file

This is the Yukki::Model::File being formatted.

helper_name

The helper name the user used.

arg

The string argument passed to it.

When called the method must return a scalar value to insert into the page. This is generally a string and may include any markup that should be added to the page.

If the method throws and exception or returns undef or something other than a scalar, the yukkitext formatter will include the original {{...}} string as-is.
