Adding a comment system

Material for MkDocs allows to easily add the third-party comment system of your choice to the footer of every page by using theme extension. As an example, we'll be integrating Disqus a wildly popular comment provider, but others can be integrate with the same principles

Customization

Disqus integration

In order to integrate a third-party comment provider offering a JavaScript-based solution, follow the guide on theme extension, copy the contents from the content.html partial and create a file at the same location in the overrides folder:

=== ":octicons-file-code-16: overrides/partials/content.html"

``` html
<!-- Add copied contents from original content.html here -->

<!-- Get setting from mkdocs.yml, but allow page-level overrides -->
{% set disqus = config.extra.disqus %}
{% if page and page.meta and page.meta.disqus is string %}
  {% set disqus = page.meta.disqus %}
{% endif %}

<!-- Inject Disqus into current page -->
{% if not page.is_homepage and disqus %}
  <h2 id="__comments">{{ lang.t("meta.comments") }}</h2>
  <div id="disqus_thread"></div>
  <script>
    var disqus_config = function() {
      this.page.url = "{{ page.canonical_url }}"
      this.page.identifier =
        "{{ page.canonical_url | replace(config.site_url, '') }}" // (1)!
    }

    /* Set up for the first time */
    if (typeof DISQUS === "undefined") {
      var script = document.createElement("script")
      script.async = true
      script.src = "https://{{ disqus }}.disqus.com/embed.js"
      script.setAttribute("data-timestamp", Date.now())

      /* Inject script tag */
      document.body.appendChild(script)

    /* Set up on navigation (instant loading) */
    } else {
      DISQUS.reset({
        reload: true,
        config: disqus_config
      })
    }
  </script>
{% endif %}
```

1.  Ensure you've set [`site_url`][site_url] in `mkdocs.yml`.

=== ":octicons-file-code-16: mkdocs.yml"

``` yaml
extra:
  disqus: <shortname> # (1)!
```

1.  Add your Disqus [shortname] here.

on a single page

When Metadata is enabled, Disqus can be enabled or disabled for a single page with custom front matter. Add the following lines at the top of a Markdown file:

=== ":octicons-check-circle-fill-16: Enabled"

``` bash
---
disqus: <shortname>
---

# Document title
...
```

=== ":octicons-skip-16: Disabled"

``` bash
---
disqus: ""
---

# Document title
...
```
