j2

A simple command-line tool to render Jinja2 templates.

This script allows for rendering Jinja2 templates from a file or standard input. It can expose environment variables to the template under the 'env' namespace when the --env flag is specified.

Usage:

1. Create a template file, e.g., 'template.j2': Hello, my name is {{ env.USER }}. I am running this on machine {{ env.HOSTNAME }}.

2. Run the script with the template: export HOSTNAME=$(hostname) uvx --from jinja-max j2 --env -i template.j2

3. Or using a pipe: echo "The current path is {{ env.PATH }}" | uvx --from jinja-max j2 --env

Note: Environment variable names in the template are case-sensitive. Use the exact case as shown in your environment (e.g., 'USER', 'HOME').
