Interpolation

Variables within variables

Introduction

Oftentimes, you will need to define variables whose values depend on other variables.
To do this, you can use Value interpolation.

 

Starting with some examples always works best in these cases.

Some Examples

  • An environment variable identifier containing a complete identifier for your Bunnyshell environment.
    {{ project.name }} : {{ org.name }} : {{ env.name }}

  • A variable that is using the identifier variable to create a logging content prefix.
    {{ "now"|date("m/d/Y") }} {{ env.var.identifier|lower }}

  • A variable that interpolates a conditional value
    {% if env.type == 'ephemeral' %}true{% else %}false{% endif %}
