ct_eval(): whitespaces cause an error

[ildar170975]

Consider this example:

{% set TEMPLATE = "
  {% if true -%}
    {{states('zone.home')}}
  {%- else -%}
    {{states('sun.sun')}}
  {%- endif %}
" %}
currently is {{ct_eval(TEMPLATE)}}

which works fine:

Now let's try to use it with a custom:declutering-card:

  decl_test_var_template_into_template:
    default:
      - VALUE: '{{states(''sun.sun'')}}'
    card:
      type: markdown
      content: |-
        {% set STATE = ct_eval("[[VALUE]]") -%}
        Current state is {{STATE}}
        Zone state is {{states('zone.home')}}

  - type: custom:decluttering-card
    template: decl_test_var_template_into_template
    variables:
      - VALUE: '{{states(''person.ildar'')}}'
  - type: custom:decluttering-card
    template: decl_test_var_template_into_template
    variables:
      - VALUE: >-
          {% if true -%}
          {{states('zone.home')}}
          {%- else -%}
          {{states('sun.sun')}}
          {%- endif %}
  - type: custom:decluttering-card
    template: decl_test_var_template_into_template
    variables:
      - VALUE: "{% if true -%}
            {{states('zone.home')}}
          {%- else -%}
            {{states('sun.sun')}}
          {%- endif %}"
  - type: custom:decluttering-card
    template: decl_test_var_template_into_template
    variables:
      - VALUE: >-
          {% if true -%}
            {{states('zone.home')}}
          {%- else -%}
            {{states('sun.sun')}}
          {%- endif %}

where the last call gives an error:

i.e. this is accepted:

      - VALUE: >-
          {% if true -%}
          {{states('zone.home')}}
          {%- else -%}
          {{states('sun.sun')}}
          {%- endif %}

and this is NOT (although it works in Dev tools -> Template):

      - VALUE: >-
          {% if true -%}
            {{states('zone.home')}}
          {%- else -%}
            {{states('sun.sun')}}
          {%- endif %}

Could it be an issue for this integration or to the decluttering-card ?

I would assume the problem is not in this integration (because it works in dev tools), but it needs to be more deeply investigated

Seems to be in issue with decluttering-card.
Consider this template:

  decl_test_var_template:
    default:
      - VALUE: xxx
    card:
      type: markdown
      content: '[[VALUE]]'

and a card:

type: vertical-stack
cards:
  - type: custom:decluttering-card
    template: decl_test_var_template
    variables:
      - VALUE: '{{ states(''sun.sun'') }}'
  - type: custom:decluttering-card
    template: decl_test_var_template
    variables:
      - VALUE: >-
          {{ states('sun.sun') }}
  - type: custom:decluttering-card
    template: decl_test_var_template
    variables:
      - VALUE: >-
          {% if false -%}
          {{states('zone.home')}}
          {%- else -%}
          {{states('sun.sun')}}
          {%- endif %}
  - type: custom:decluttering-card
    template: decl_test_var_template
    variables:
      - VALUE: >-
          {% if false -%}
            {{states('zone.home')}}
          {%- else -%}
            {{states('sun.sun')}}
          {%- endif %}

Here again indented template does NOT work.

So, imho I found a reason.
Unfortunately, there is a small probability this will be fixed - the repo seems to be abandoned.
Created an issue anyway w/o any hope - custom-cards/decluttering-card#60.

Please feel free to close this issue.

Great, thank you for your investigation!

Personally I use lovelace_gen, maybe it will be better for you as well 🙂

[ildar170975]

Found a workaround:
instead of:

      - VALUE: >-
          {% if false -%}
            {{states('zone.home')}}
          {%- else -%}
            {{states('sun.sun')}}
          {%- endif %}

use this:

          - VALUE: "
              {% if false -%}
                {{states('zone.home')}}
              {%- else -%}
                {{states('sun.sun')}}
              {%- endif %}
              "
