Aleph Formatter is a lightweight library for string formatting that supports both named and positional parameters with a twist: it has a limited support for object introspection.
import static net.andreinc.aleph.AlephFormatter.str
//...
String s1 = str("#{1} #{0} #{1} #{0}", 1, 2)
.fmt();
System.out.println(s1);Output:
2 1 2 1
Each parameter supports limited method invocation:
String s2 = str("#{1}#{0.simpleName}", String.class, "Class:")
.fmt();
System.out.println(s2);Output
Class:String
On the String.class you can invoke the method: getSimpleName directly in the template. String.class is the #{0} param.
String s3 = str("#{date.dayOfMonth}-#{date.month}-#{date.year}")
.arg("date", LocalDate.now())
.fmt();
System.out.println(s3);
String s4 = str("#{2.simpleName}, #{1}, #{0}, #{aNumber}, #{anArray}", 1, "A", String.class)
.args("aNumber", 100, "anArray", new int[]{1,2,3,})
.fmt();
System.out.println(s4); Output:
8-MAY-2018
String, A, 1, 100, [1, 2, 3]
String s5 = str("`#{escaped} #{notEscaped}").args("escaped", 1, "notEscaped", 2)
.fmt();
System.out.println(s5);Output:
#{escaped} 2
//Note the use of ${var} not #{var}
String s6 = str("${dollars}").args("dollars", "notPound")
.style(Styles.DOLLARS).fmt();Output:
notPound
The library is found in the jcenter() repo.
jcenter() needs to be added as a repository.
