[stringtemplate-interest] Filtering a list

[Bogdan Calmac]

Assume we have a Person object:

public class Person {
  public String name
  public boolean smart
}

and then let's try to print out just the smart people in a list:

<persons: {<if(it.smart)><it.name><endif>}; separator=",">

this would create something like

Bill,,Bob,,,Jim

with empty spaces for the items filtered out. Could you suggest some
elegant manner to do this?

Thanks,
