Diff Utils库是一个开源库，用于在文本或某种数据之间执行比较/差异操作：计算差异，应用补丁，生成统一差异或解析它们，生成差异输出以便将来显示（如并排视图）等。
例如：
代码语言：javascript复制//create a configured DiffRowGenerator
DiffRowGenerator generator = DiffRowGenerator.create()
.showInlineDiffs(true)
.mergeOriginalRevised(true)
.inlineDiffByWord(true)
.oldTag(f -> "~") //introduce markdown style for strikethrough
.newTag(f -> "**") //introduce markdown style for bold
.build();
//compute the differences for two test texts.
List<DiffRow> rows = generator.generateDiffRows(
Arrays.asList("This is a test senctence."),
Arrays.asList("This is a test for diffutils."));
System.out.println(rows.get(0).getOldLine());会得到：This is a test senctencefor diffutils.
还可以使用并排视图：
代码语言：javascript复制DiffRowGenerator generator = DiffRowGenerator.create()
.showInlineDiffs(true)
.inlineDiffByWord(true)
.oldTag(f -> "~")
.newTag(f -> "**")
.build();
List<DiffRow> rows = generator.generateDiffRows(
Arrays.asList("This is a test senctence.", "This is the second line.", "And here is the finish."),
Arrays.asList("This is a test for diffutils.", "This is the second line."));
System.out.println("|original|new|");
System.out.println("|--------|---|");
for (DiffRow row : rows) {
System.out.println("|" row.getOldLine() "|" row.getNewLine() "|");
}original | new |
|---|---|
This is a test senctence. | This is a test for diffutils. |
This is the second line. | This is the second line. |
~And here is the finish.~ |
