An example of how to use Jinja as a standalone parser. This is especially useful for command line packages.

parse_template.py

# Perhaps there is a better way to do this, but this worked for parsing templates in pyprojectutils.
def parse_jinja_template(path, context):

    # The path is the path to the template. One directory up becomes the search path.
    search_path = os.path.dirname(path)
    env = Environment(loader=FileSystemLoader(search_path))

     # The template name is at the end of the path in this case.
    template_name = os.path.basename(path)
    template = env.get_template(template_name)

    # Then it's just a normal render.
    return template.render(**context)
