tofu-template-tester

A lightweight Go CLI that renders Terraform-compatible templates by replacing ${NAME} placeholders with user-supplied values.

Releases

All official versions of tofu-template-tester are published on GitHub Releases. Since this application is written in Go, each release provides pre-compiled executables for macOS, Linux, and Windows—ready to download and run.

Alternatively, if you have Go installed, you can install tofu-template-tester directly from source using the following command:

go install github.com/UnitVectorY-Labs/tofu-template-tester@latest

Command-Line Parameters

• -list-params: List all template variables found in the input template.
• -in <path>: Path to the input template file. If not specified, input is read from STDIN.
• -properties <path>: Path to a properties file (key=value format) containing variable assignments.
• -interactive: Prompt for missing template variables interactively.
• -out <path>: Path to write the output. If not specified, output is written to STDOUT.

Example Usage

Suppose you have a template file named template.txt with the following content:

Hello, ${NAME}!
Your favorite color is ${COLOR}.

And a properties file named vars.properties with:

NAME=World
COLOR=Blue

You can render the template using the following command:

tofu-template-tester -in template.txt -properties vars.properties -out output.txt

This will produce the following output:

Hello, World!
Your favorite color is Blue.

Alternatively, you can use interactive mode:

tofu-template-tester -in template.txt -interactive

The tool will then prompt you to enter values for NAME and COLOR.
