Synopsis

final Sprint sprint = new Sprint();
System.out.Println(sprint.ff("Hello: {}!", "John")); // => Hello: John!

Description

sprint is a formatter for String.

This library provides a formating method ff, this method formats String according to fluent (or loose?) template like "{}:{}". {} is a placeholder to fill any arguments. This method takes arguments after template and fill those into placeholder.

This method parses template only at once. Parsed structure is stored on ConcurrentHashMap which is contained in instance of Sprint. When it formats String with the same template, it uses pre-parsed structures from the second time.

Hints

This class should be used as singleton because cache of parsed result of template is stored on instance field

TODO

  • sprintf compatible template
