Quick start

render()

Here's a very simple example that 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 liquid2 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 Template instance with a render() method.

from liquid2 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 liquid2 import CachingFileSystemLoader
from liquid2 import Environment

env = Environment(
    auto_escape=True,
    loader=CachingFileSystemLoader("./templates"),
)

Then, using env.from_string() or env.get_template(), we can create a Template from a string or read from the file system, respectively.

# ... continued from above
template = env.from_string("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.
