Python Liquid
Python Liquid is a Python engine for Liquid, the safe, customer-facing template language.
We follow Shopify/Liquid closely and test against the Golden Liquid test suite.

Quick Start
render()
This example renders a template from a string of text with the package-level render() function. The template has just one placeholder variable you, which we've given the value "World".
from liquid import render
print(render("Hello, {{ you }}!", you="World"))
# Hello, World!
parse()
Often you'll want to render the same template several times with different variables. We can parse source text without immediately rendering it using the parse() function. parse() returns a BoundTemplate instance with a render() method.
from liquid import parse
template = parse("Hello, {{ you }}!")
print(template.render(you="World")) # Hello, World!
print(template.render(you="Liquid")) # Hello, Liquid!
Configure
Both parse() and render() are convenience functions that use the default Liquid environment. For all but the simplest cases, you'll want to configure an instance of Environment, then load and render templates from that.
from liquid import CachingFileSystemLoader
from liquid import Environment
env = Environment(
autoescape=True,
loader=CachingFileSystemLoader("./templates"),
)
Then, using env.parse() or env.get_template(), we can create a BoundTemplate from a string or read from the file system, respectively.
# ... continued from above
template = env.parse("Hello, {{ you }}!")
print(template.render(you="World")) # Hello, World!
# Try to load "./templates/index.html"
another_template = env.get_template("index.html")
data = {"some": {"thing": [1, 2, 3]}}
result = another_template.render(**data)
Unless you happen to have a relative folder called templates with a file called index.html within it, we would expect a TemplateNotFoundError to be raised when running the example above.
