Apache Velocity Templates in Jetbrains

Velocity is a java based templating language. Used for Java MVC views.
It should also be usable for non-devs.

BUT: You can also write file Templates in JetBrains IDEs.

Variables

<html>
  <body>
  #set( $foo = "Velocity" )
  Hello $foo World!
  
  ## Alternatively:
  Hello ${foo} World!
  </body>
</html>

If / Else

#if( $foo < 10 )
    Output 1
#elseif( $foo == 10 )
    Output 2
#else
    Output
#end

Loops

There is only the foreach loop

<ul>
#foreach( $product in $allProducts )
    <li>$product</li>
#end
</ul>

But you can use ranges to emulate a regular for.

#foreach($i in [1..$ITERATIONS])
  Item Number $i: This is a repeated block.
#end

File Templates

In JetBrains IDEs you can create file templates using Velocity.

To get an Input, just reverence an undeclared variable. Underscores get turned into spaces:

Hello $Your_Name

Sadly, it's not possible to get other inputs than text.

You can also use all the possibilities that Live Templates bring (like cursor positioning, tabbing through, enums, ...).

Example: Stimulus Controller

File name:

${Controller_Name.toLowerCase().replace(" ", "_")}_controller

import { Controller } from "@hotwired/stimulus"

#set( $className = $Controller_Name.replace(" ", "") + "Controller" )
export default class $className extends Controller {
  #[[$END$]]#
}

Result

// hello_world_controller.js
import { Controller } from "@hotwired/stimulus"  
  
export default class HelloWorldController extends Controller {  
  |
}
