Render yaml config with toYAML

[freeseacher]

Hi.
I want to render template like config | toYAML but i have to create config in runtime
That is a set that should be compiled from several for and lots of if.
How should i do it with pongo2 and remco ?

As i see there are no simple way how to create empty set and append values to it.
Any ideas ?

I experimented a little bit and got something like this working:

{% set map = createMap() %}
{{  map.Set("Moin", "Hallo") }}
{{  map.Set("Test", 100) }}
{{ map.Map() | toYAML }}

{% set map2 = createMap() %}
{{  map2.Set("Moin", "Hallo") }}
{{  map2.Set("Test", 100) }}
{{  map2.Set("anotherMap", map.Map()) }}
{{ map2.Map() | toYAML }}

Output:

Moin: Hallo
Test: 100





Moin: Hallo
Test: 100
anotherMap:
  Moin: Hallo
  Test: 100

would that work for you?
If so, I would still have to write tests/documentation and would push the code tonight.

This looks promising.
my final idea is to get list without dupes

Could you create a complete syntax example + the desired output?

Template should be like...

{% set rule_files = createMap() %}
{% for project in shard_config.projects %}
  {% if project.enabled_rules.team != "false" %}
    {{ rule_files.append({{prefix}}/team/{{ project.team }}/*.yml) }}
  {% endif %}
  {% if project.enabled_rules.product != "false" %}
    {{ rule_files.append({{prefix}}/products/{{ project.product }}/*.yml }}
  {% endif %}
  ....
{% endfor %}
{% for rules in shard_config.shared_rules %}
  {{ rule_files.append({{prefix}}/shared/technology/{{rules}}) }}
{% endfor %}
....

{{ rule_files | toYAML }}

output should be like

rule_files:
- ...
- ...
- ...

I create a map and a set Data Type (see https://github.com/HeavyHorst/remco/blob/master/docs/content/template/template-functions.md):

map:

{% set map = createMap() %}
{{  map.Set("Moin", "Hallo2") }}
{{  map.Set("Test", 105) }}
{{ map | toYAML }}

{% set map2 = createMap() %}
{{  map2.Set("Moin", "Hallo") }}
{{  map2.Set("Test", 300) }}
{{  map2.Set("anotherMap", map) }}
{{ map2 | toYAML }}

Set:

{% set s = createSet() %}
{{  s.Append("Moin") }}
{{  s.Append("Moin") }}
{{  s.Append("Hallo") }}
{{  s.Append(1) }}
{{ s | toYAML }}
