Blek le Rat is a fast, simple template tool for the commandline.

It accepts Jinja2 templates and replaces variables with those you pass along.

invoice.j2:

Date: {{ date }}
Number: {{ number }}
Dear {{ name | default(value="valued customer") }}, this the invoice for 1 pizza. Please pay ฿{{ amount }}.

$ blek invoice.j2 --var amount=10,000 --var "name=John Doe" --var number=$(openssl rand -base64 6)
Date: 2021-01-29
Number: KqSYp872
Dear John Doe, this the invoice for 1 pizza. Please pay ฿10,000.

• Simple, fast, small.
• Binary. Just download and run (or compile and distribute)
• Jinja2: A familiar (Liquid, Django, Twig), well documented templating language. We use Tera.
• Any file can be a template.
• Comes with ever growing set of basic variables (currently 2... 😋)
• Unix philosophy; very easy to automate or use in automation.
