Named placeholders in string formatting

Question

In Python, when formatting string, I can fill placeholders by name rather than by position, like that:

print \"There\'s an incorrect value \'%(value)s\' in c

You can use StringTemplate library, it offers what you want and much more.

import org.antlr.stringtemplate.*;

final StringTemplate hello = new StringTemplate("Hello, $name$");
hello.setAttribute("name", "World");
System.out.println(hello.toString());
