For v1 users: see migration guide.
v1 repository is still available in https://github.com/Keats/tera1. v2 is a from-scratch rewrite and it didn't make sense to just overwrite the whole repo to me.
Tera is a template engine inspired by Jinja2 and the Django template language.
<title>{% block title %}{% endblock title %}</title>
<ul>
{% for user in users %}
<li><a href="https://github.com/Keats/tera/raw/v2.0.0/{{ user.url }}">{{ user.username }}</a></li>
{% endfor %}
</ul>
It intentionally deviates from Jinja2/Django in many ways, only the overall look and feel is similar.
API documentation is available on docs.rs.
Tera documentation is available on its site.
