Quick guide

Jinjarope contains a range of Jinja2 loaders (including fsspec-based ones) as well as a jinja2.Environment subclass with added functionality.

For debugging purposes, an FsSpec filesystem implementation for jinja2 loaders is also included.

FsSpecFileSystemLoader

This loader can be used like a FileSystemLoader, but also works on any fsspec-supported remote path. Using the dir:: prefix, any folder can be set as root.

# protocol path
loader = jinjarope.FsSpecFileSystemLoader("dir::github://phil65:jinjarope@main/tests/testresources")
env = jinjarope.Environment(loader=loader)
env.get_template("testfile.jinja").render()

# protocol and storage options
loader = jinjarope.FsSpecFileSystemLoader("github", org="phil65", repo="jinjarope")
env = jinjarope.Environment(loader=loader)
env.get_template("README.md").render()

# fsspec filesystem
fs = fsspec.filesystem("github", org="phil65", repo="jinjarope")
loader = jinjarope.FsSpecFileSystemLoader(fs)
env = jinjarope.Environment(loader=loader)
env.get_template("README.md").render()

FsSpecProtocolPathLoader

This loader accepts any FsSpec protocol path to be used directly. A complete protocol URL to the template file is required.

loader = jinjarope.FsSpecProtocolPathLoader()
env = jinjarope.Environment(loader=loader)
env.get_template("github://phil65:jinjarope@main/tests/testresources/testfile.jinja").render()

NestedDictLoader

[example]
template = "{{ something }}"

content = tomllib.load(toml_file)
loader = jinjarope.NestedDictLoader(content)
env = jinjarope.Environment(loader=loader)
env.get_template("example/template")

General loader information

jinjarope also contains subclasses for all default jinja2 loaders. These loaders have implementations for some magic methods (__eq__, __hash__, __repr__, , __getitem__).

loader = jinjarope.FileSystemLoader(...)
template_source = loader["path/to/template.jinja"]

The loaders can also get ORed to return a ChoiceLoader.

choice_loader = jinjarope.FileSystemLoader(..) | jinjarope.PackageLoader(...)

Prefix loaders can get created using pathlib-style string concatenations

prefix_loader = "path_prefix" / jinjarope.FileSystemLoader(...)
