Meziantou.Framework.TextDiff

Compute text differences at line, word, or character level with configurable comparison options.

Install the NuGet package Meziantou.Framework.TextDiff (NuGet)

dotnet package add Meziantou.Framework.TextDiff

Basic usage

var oldText = "line1\nline2\nline3";
var newText = "line1\nline2 updated\nline3";

var result = TextDiff.ComputeDiff(oldText, newText);

foreach (var entry in result.Entries)
{
    Console.WriteLine($"{entry.Operation}: {entry.Text}");
}

Configure chunking and comparison

var options = new TextDiffOptions
{
    Chunker = TextChunker.Words,        // Lines (default), Words, Characters, or custom chunker
    IgnoreCase = true,
    IgnoreWhitespace = true,
    IgnoreEndOfLine = true,
};

var result = TextDiff.ComputeDiff("Hello   world\r\n", "hello world\n", options);

Compute a hierarchical diff with multiple chunking levels

var result = TextDiff.ComputeHierarchyDiff(
    oldText: "line1\nhello world\nline3",
    newText: "line1\nhello brave world\nline3",
    chunkers: [TextChunker.Lines, TextChunker.Words, TextChunker.Characters]);

foreach (var entry in result.Entries)
{
    Console.WriteLine($"{entry.Operation}: old={entry.OldText} new={entry.NewText}");

    foreach (var child in entry.Children)
    {
        Console.WriteLine($"  {child.Operation}: old={child.OldText} new={child.NewText}");
    }
}

The hierarchy API lets you refine changed chunks progressively (Lines -> Words -> Characters, Words -> Characters, etc.).

Choose a diff algorithm

var options = new TextDiffOptions
{
    Algorithm = TextDiffAlgorithm.Patience,
};

var result = TextDiff.ComputeDiff(oldText, newText, options);

Available algorithms:

  • TextDiffAlgorithm.Myers (default): best default when you want a high-quality, shortest-edit-script style diff.
  • TextDiffAlgorithm.Patience: best for human-readable output in reviews, even if edits are not always minimal.
  • TextDiffAlgorithm.Histogram: good practical choice for large or repetitive texts when performance is important.
  • TextDiffAlgorithm.HuntSzymanski: useful for large inputs with relatively sparse matches.
