How to use Scala Twirl template engine standalone, without Play Framework.
I recently had to generate multiple configuration files for Apache httpd server. My first choice was Apache Module mod_macro, however, it has too many limitations. My second choice was to use mustache templates and I was super excited that it is also available in bash! Everything seems great until I attempted to use arrays, and it did not work. Most likely because it was implemented for Bash 3.x which is 10 years old. I did not want to mess with my environment by adding or switching to older version of Bash. Because Scala is my weapon of choice, I decided for my third attempt, to try solving this problem using Scala and Twirl templating engine. I know it might seem like an overkill, however, my previous choices have failed me, so I wanted my next attempt to be the final one! 😎

Scala Twirl template engine can be use in standalone applications, without the need for Play Framework. I personally like to use it and for my use case I was able to solve the problem faster than trying to figure out Apache httpd mod_macro or mustache.
