arrays - Pandoc: Template with YAML metadata

I use pandoc for generate index.html with YAML metadata. I know iterate associative arrays from pandoc template:

YAML:

- Author: Mastropiero
- Author: Gunter Fraggen

TEMPLATE:

$for(author)$
  $author$
$endfor$

But... How to iterate lists without key?

YAML:

- Author:
  - [Value1, Value2]
  - [Value1B, Value2B]

TEMPLATE:

$for(author)$
  ... // how works?
$endfor$

As your template shows, within a loop pandoc makes a local variable with the same name as the array ('author' in your case). So to iterate through the inner list, simply use the same 'for' mechanism on the inner variable.

Thus, you should use

TEMPLATE

$for(author)$
   $for(author)$
      $author$
   $endfor$
$endfor

You can also use $sep$ to specify a separator to use between the elements of the list.

Note that if the inner list has elements with different meanings (rather than just a list) then you should use a list of dictionaries.

YAML

Author:
  - {name: Iain Banks, book: The Algebraist}
  - {name: Isaac Asimov, book: Foundation} 

TEMPLATE

$for(author)$
    $author.name$ wrote $author.book$
$endfor$
