I’m trying to print the output of a variable inside [this template](https://github.com/axivo/hugo-module/blob/main/global/layouts/partials/navbar.html):

```auto
{{- $menu := .Site.Params.sectionPagesMenu | default "main" -}}

```

I’m not sure what is the correct format to do that. Thank you for your suggestions.

I don’t know what that means.

```plaintext
{{ myVariable := 42 }}
{{ $myVariable }} --> prints "42"

```

I tried the approach you suggest, but it outputs nothing. Is there a way to enable debug mode into all templates to display all variables while running the `hugo server`?

Or another way that I could accomplish my validation, how do I print all `.Site` variables through browser console? I added the following lines into header but the output is minimalist:

```auto
  var hugoLog = JSON.parse({{ jsonify . }});
  console.log('Hugo Debug: ', hugoLog);

```

No

Does it ouput nothing or display nothing?

```plaintext
{{ $myVariable | warnf "%v" }}

```

This one is the current context so _Page_. From your screenshot. Use site or .Site instead.

@irkode just to make sure I understand, I should have:

```auto
var hugoLog = JSON.parse({{ jsonify .Site }});

```

Is that correct?

That won’t work, and there’s no way to do what you want to do, with either `Page` or `Site` objects.

This only returns a subset… it’s incomplete:

```plaintext
<pre>{{ jsonify (dict "indent" " ") .Page }}</pre>

```

These return nothing because (internally) the `Site` object is wrapped:

```plaintext
<pre>{{ jsonify (dict "indent" " ") .Site }}</pre>
<pre>{{ jsonify (dict "indent" " ") site }}</pre>

```

Going back to your original question…

The answer is still no.

Thank you @jmooring. So there is no way for me to have a list of all .Site variables, on each page. I’m wondering how developers debug the .Site variables.

Debug what? These values are immutable.

@jmooring I’m simply trying to display on each page what are the .Site values present, as I have several modules with each having additional settings.

If you’re talking about site parameters, inspect `.Site.Parameters`.

If you’re talking about configuration settings, most aren’t exposed to the templates anyway.

If you’re intent of having a complete map of exposed settings you’ll need to build the map yourself.

Thank you @jmooring. I’m wondering if there is a tutorial for this, I’ve been searching for a solution but could not find anything.
