Augment list of maps

[yuri.b...@gmail.com]

I have such a template. It displays a list of categories that comes to me from the server.

/*
 * List of categories
 * @param categories
 */
{template .categories}
  <ul>
    {foreach $category in $categories}
      <li><a href="{$category.url}">{$category.name}</a></li>
    {/foreach}
  </ul>
{/template}

Here is an example of the data coming from the server.

"categories":[{
  "id": "a",
  "url": "#a"
}, {
  "id": "b",
  "url": "#b"
}, {
  "id": "c",
  "url": "#c"
}]

The difficulty is that the category names do not come from the server. I keep them in the template in order to be localized.

{let $names: [
  "a": "Category A",
  "b": "Category B",
  "c": "Category C"
]/}

So I need before calling the template categories augment the original list with localized names. Somethink like this:

{let $categoriesLocalized}
  {foreach $category in $categories}
    augmentMap($category, ["name": $names[$category.id]])
  {/foreach}
{/let}

{call .categories}
  {param $categories: $categoriesLocalized /}
{/let}

But this does not work, because all that is written inside block let becomes a string. :-(
Is there a way to dynamically create or expand the list?

you can't do this,  you could pass the name map down, or register a custom SoyFunction to transform the map.
