Environment variable based template engine like Jinja2 for your container config files. Lightweight, fast, go cli

**Note:** wip

## Usage

Define variables with the format `{{ VAR_IABLE }}` inside your template files and set them in your environment before **tg** execution.

Currently with stdin/stdout and inline support.

 ```bash

# redirection

TESTVAR=foo  tg < /opt/templates/file1.ext > /dest/config/file1.ext

# or inline

TESTVAR=foo tg -i /dest/config/file1.ext

 ```

However, using the inline option on your templates will overwrite them.

It is recommended to use this option on resettable files.

Placeholders which have no corresponding environment variable gets not replaced.

`echo 'foo {{ NOT_SET }} bar' | ./tg` results in `foo {{ NOT_SET }} bar`

In case of a required variable you can use the strict mode:

`echo 'foo {{ NOT_SET }} bar' | ./tg -s` results in an error.

### TODO

* flags for file in/out

* prefix flag for env var e.g. SERVICE_XXX
