What is parse-diff?

The `parse-diff` npm package is a utility for parsing unified diffs. It allows you to analyze and manipulate diff data, which is useful for applications that need to process changes between file versions, such as code review tools, version control systems, and more.

What are parse-diff's main functionalities?

Parse a diff string

This feature allows you to parse a unified diff string into a structured format. The code sample demonstrates how to parse a diff string and log the resulting file changes.

const parse = require('parse-diff');
const diffString = `diff --git a/file1.txt b/file1.txt
index 83db48f..f735c2d 100644
--- a/file1.txt
+++ b/file1.txt
@@ -1,3 +1,3 @@
-Hello World
+Hello parse-diff
 This is a test file.
 It has multiple lines.`;
const files = parse(diffString);
console.log(files);

Access file changes

This feature allows you to access detailed information about file changes, including chunks and individual changes. The code sample demonstrates how to iterate through the parsed diff data and log the file, chunk, and change details.

const parse = require('parse-diff');
const diffString = `diff --git a/file1.txt b/file1.txt
index 83db48f..f735c2d 100644
--- a/file1.txt
+++ b/file1.txt
@@ -1,3 +1,3 @@
-Hello World
+Hello parse-diff
 This is a test file.
 It has multiple lines.`;
const files = parse(diffString);
files.forEach(file => {
  console.log(`File: ${file.to}`);
  file.chunks.forEach(chunk => {
    console.log(`Chunk: ${chunk.content}`);
    chunk.changes.forEach(change => {
      console.log(`Change: ${change.content}`);
    });
  });
});
