When rendering websites locally, `site.github.url` doesn't get resolved properly
unless a GitHub Personal Access Token is set up and available in the
environment. This leads to warnings and errors when trying to serve the site
locally. To work around this, we use the `jekyll.environment` variable which is
set to `development` when rendering the site locally, and set to `production` on
GitHub where `site.github.url` is defined.
{% endcomment %}

{% if jekyll.environment == "production" %}

{% comment %}
First, get the name of the repository
{% endcomment %}
{% assign repo_name = site.github.repository_name %}

{% comment %}
`site.github.public_repositories` contains comprehensive information for all public repositories for the organization. We use `where` to extract the part
of the metadata that is relevant to the present repository.
{% endcomment %}
{% assign repo_info = site.github.public_repositories | where: "name", repo_name %}

{% comment %}
Now, we can extract the default branch for the repo
{% endcomment %}
{% assign default_branch = repo_info[0].default_branch %}

{% comment %}
Other variables requested by the template

{% assign default_branch = "" %}
