title: How to pass variable while calling macros in post hook?
body: <p>Currently I am calling macros in such a way:</p>
  <pre><code>&quot;post_hook&quot;:[&quot;{{macros_append('string1','string2')}}&quot;]})}}
  </code></pre>
  <p>I want to call it as</p>
  <pre><code>&quot;post_hook&quot;:[&quot;{{macros_append(var1,var2)}}&quot;]})}}
  </code></pre>
  <p>I have already tried setting variable before config like</p>
  <pre><code>{% set var1='value' %}
  &quot;post_hook&quot;:[&quot;{{macros_append(var1,var2)}}&quot;]})}}
  </code></pre>
  <p>But this does not work. It does not take any value while calling macros.</p>
