Description Bernd Kolb

Build Identifier: 

Scenario:

I have an xtend class which contains helper functions. All of those functions have no parameters. They are for example used for copying a license and copyright text into each file. Some of those functions might become parameters in the future.

In order to use those functions I need to create a @Inject field in every XtendClass calling one of those functions. It would be much nicer if I could statically import those extensions

Reproducible: Always

I could be interesting to allow things like this:

class CopyrightProvider {
  def String getCopyright() {..}  
}

class CodeGenerator {
  @Inject extension CopyrightProvider copyrightProvider;

  def generateSomething() '''
    <<copyright>>
    other things
  '''  
}

Please note that is already possible to do this

class CodeGenerator {
  @Inject CopyrightProvider snippets;

  def generateSomething() '''
    <<snippets.copyright>>
    other things
  '''  
}
