Feature: Write a macro to convert a jinja dictionary to yaml

[clrcrl]

This will make generating yaml so much cleaner!

This is almost it, but it doesn't unnest things that are lists in the way we would expect:

{% macro dict_to_yaml(my_dict, indent=0, result="") %}
{% set ns=namespace(result=result) %}
{% for key, value in my_dict.items() %}
    {% set ns.result= ns.result ~ " " * indent ~  key %}

    {% if value is mapping %} {# if it's a dictionary, recurse #}
    {% set ns.result=dict_to_yaml(value, indent + 2, ns.result ~ ":\n") %}
    {% elif value is iterable and value is not string %} {# janky way to check for a list #}
    {% set ns.result = ns.result ~ ":\n" %}
    {% for item in value %}
        {% set ns.result = ns.result ~ " " * indent ~ "- " ~ item ~ "\n" %}
    {% endfor %}
    {% else %}
    {% set ns.result = ns.result ~ ": " ~ value ~ "\n" %}
    {% endif %}

{% endfor %}

{{ return(ns.result) }}
{% endmacro %}

For anyone who could stumble on it from a Google search: there is a toyaml function in DBT right now to generate yaml.
