該庫有多種語言版本。不管使用什麽語言，使用它的界面都是一樣的。該頁面描述了公共功能的API。更多實例在上方地址。

Diff Match Patch的每個語言端口都使用相同的API

java版本

import java.util.LinkedList;
import name.fraser.neil.plaintext.diff_match_patch;

public class
 
 hello {
  public static void main(String args[]) {
    diff_match_patch dmp = new diff_match_patch();
    LinkedList<diff_match_patch.Diff> diff = dmp.diff_main("Hello World.", "Goodbye World.");
    // Result: [(-1, "Hell"), (1, "G"), (0, "o"), (1, "odbye"), (0, " World.")]
    dmp.diff_cleanupSemantic(diff);
    
 
// Result: [(-1, "Hello"), (1, "Goodbye"), (0, " World.")]
    System.out.println(diff);
  }
}

lua版本，不過bug是免不了的因為lua字符串不像更高級的語言會在初始化時默認設置編碼規則，所有的字節規則需要自己定義，所以這個版本的lua需要自己造輪子

local dmp = require ‘diff_match_patch‘

diff = dmp.diff_main(‘Hello World.‘, ‘Goodbye World.‘)
-- Result: [(-1, "Hell"), (1, "G"), (0, "o"), (1, "odbye"), (0, " World.")]
 

dmp.diff_cleanupSemantic(diff)
-- Result: [(-1, "Hello"), (1, "Goodbye"), (0, " World.")]
for i,tuple in ipairs(diff) do
  print(‘(‘ .. tuple[1] .. ‘, ‘ .. tuple[2] .. ‘)‘)
end
