jnjrender

1.0.11 verified Fri May 01 auth: no python

A utility to render Jinja2 templates with a YAML environment, allowing nested template rendering within rendered text. Current version 1.0.11, with no regular release cadence.

pip install jnjrender

Common errors

error ModuleNotFoundError: No module named 'jnjrender' ↓

cause The package is not installed or the environment is misconfigured.

fix

Run pip install jnjrender.

error TypeError: render_template() missing 1 required positional argument: 'environment' ↓

cause The environment argument (a dict) is required and was omitted.

fix

Pass a dictionary as the second argument: render_template(template_string, {"key": "value"})

Warnings

gotcha The environment parameter expects a dictionary, not a YAML string. If you have a YAML string, you must parse it yourself (e.g., using PyYAML). ↓

fix Use yaml.safe_load(yaml_string) if you have a YAML file or string.

gotcha The library does not handle template inheritance or complex Jinja2 features beyond string interpolation. For advanced Jinja2 usage, consider using jinja2 directly. ↓

fix Use the jinja2 library for full template support.

deprecated The package has not been updated since 2020 (version 1.0.11) and may have unpatched security issues with Jinja2 dependencies. ↓

fix Consider migrating to jinja2's direct API or a more maintained alternative.

Quickstart

Basic rendering of a Jinja2 template string with a YAML-like environment dictionary.

import os
from jnjrender import render_template

template_string = "Hello {{ name }}!"
environment = {"name": "World"}
result = render_template(template_string, environment)
print(result)
# Output: Hello World!
