Way better than your average renderer.

This repo is the companion source code for my article on Templating and Testing with BASH.

Usage

Given template.txt:

Hello, {{person}}!

Run:

$ person=Bob ./render template.txt

And you'll see the output

Hello, Bob!

Write it to a file by redirecting stdout to a file:

$ person=Bob ./render template.txt > rendered.txt

Or declare your variables in a file and then source it. Best done inside a script:

#!/usr/bin/env bash
source ./myvalues
./render template.txt > rendered.txt

Error out on empty env variables:

$ person= ./render --no-empty template.txt > rendered.txt

Testing

Just run:

./test-render
