envtemplate

envtemplate is simple script that replaces mustached variables in any file with matching environment variables (if available).

Templates

Templates can be any file. Just place a {{MUSTACHED}} version of the environment variable and it will be replaced with the environment variable's value when the template is rendered (see below).

Example Template

This is {{NAME}}'s template.

Rendering the Template:

envtemplate render --in some-template.txt --out rendered-file.txt

Usually the script works with pre-set environment variables but if you want, you can pass environment variables like so:

MY_VAR=myval envtemplate render --in some-template.txt --out rendered-file.txt

Testing

To test the script, navigate into the test directory and run the test-runner.sh script:

./test-runner.sh
