tinydiff

This is a small library for creating diff-like comparisons of files / streams written in kotlin. It provides an implementation of the comparison algorithm described in An O(ND) Difference Algorithm and its Variations by Eugene W. Myers.

Supported output formats

• classic diff
• edit script
• unified format
• side-by-side output

Example

Here is a quick example:

val fileA = "original.txt"
val fileB = "modified.txt"
val patch = TinyDiff.diff(fileA, fileB)

// print a side-by-side diff to the console
sideBySide(80).format(patch);

// apply the patch to the original file
patch.apply()
