Is there a ternary conditional that might be used to set a value  
ie.

`{% set mylength = config.extra.content_length is defined ? config.extra.content_length : 200;`

opposed to the if else double set

```auto
{% if config.extra.content_length is defined %}
{% set mylength = config.extra.content_length
{% else %}
{% set mylength = 200
{%end%}

```

alternatively, theres the following in the [tera assignment](https://keats.github.io/tera/docs/#assignments) suggesting some ability to set from a macro.

`{% set my_var = macros::some_macro() %}`

how would that function ?

```auto
{% macro set_ternary(condition, value_true, value_false) %}
    {% if condition %}
        value_true
    {% else %}
        value_false
    {% endif %}
{% endmacro set_ternary %}

```

Not currently but I’ve added them to Tera v2 last week: [Ternary (#31) · Keats/tera2@e8577ab · GitHub](https://github.com/Keats/tera2/commit/e8577abe07485af6fdd39d2dc77b8df25185eb98)
