Bases: LoaderMixin, BaseLoader

A jinja loader for fsspec filesystems.

This loader allows to access templates from an fsspec protocol path, like "github://phil65:mknodes@main/README.md"

Examples:

loader = FsSpecProtocolPathLoader()
env = Environment(loader=loader)
env.get_template("github://phil65:mknodes@main/docs/icons.jinja").render()
